Sample records for acquisition data

  1. Data acquisition

    From the inception of the International Cooperative Group on Cyclic Crack Growth (ICCGR), it was recognised that its main objective was ultimately to provide a reliable and consistent data base on environmental cracking rates in pressure vessel steels, together with suitable analysis, as a basis for improvements or modification as required of ASME Section XI Appendix A. Therefore, a forum was provided for presentation of new experimental results from corrosion fatigue and stress corrosion crack growth experiments in Task Group I. This enabled early opportunity to peer review, a chance to see how individual laboratory results fitted into the developing international picture, opportunity to redirect national programmes more precisely on to areas of greatest uncertainty and to provide the raw material for the Mechanisms and Applications task groups to work with. Over the last 10 years, there has been a gradual shift of emphasis. In the early years, much effort was devoted to the development of acceptable testing practices such as monitoring techniques for remotely sensing crack extension in specimens contained in autoclaves and for checking the environmental conditions experienced by the test specimens. Latterly, experimental work has been clearly focused on the principal parameters affecting environmental cracking rates, notably steel sulphur content and morphology. The main achievements in these areas are reviewed below, highlighting the main points from earlier reviews and developments since. (author)

  2. Data acquisition system

    The topic of this paper deals with a multi parametric acquisition system developed around a four input Analog to Digital Converter working in CAMAC Standard. The acquisition software is built in MS Visual C++ on a standard PC with a USB interface. It has a visual interface which permits Start/Stop of the acquisition, setting the type of acquisition (True/Live time), the time and various menus for primary data acquisition. The spectrum is dynamically visualized with a moving cursor indicating the content and position. The microcontroller PIC16C765 is used for data transfer from ADC to PC; The microcontroller and the software create an embedded system which emulates the CAMAC protocol programming, the 4 input ADC for operating modes ('zero suppression', 'addressed' and 'sequential') and handling the data transfers from ADC to its internal memory. From its memory the data is transferred into the PC by the USB interface. The work is in progress. (authors)

  6. VERITAS Data Acquisition

    Hays, E

    2007-01-01

    VERITAS employs a multi-stage data acquisition chain that extends from the VME readout of custom 500 MS/s flash ADC electronics to the construction of telescope events and ultimately the compilation of information from each telescope into array level data. These systems provide access to the programming of the channel level triggers and the FADCs. They also ensure the proper synchronization of event information across the array and provide the first level of data quality monitoring. Additionally, the data acquisition includes features to handle the readout of special trigger types and to monitor channel scaler rates. In this paper we describe the software and hardware components of the systems and the protocols used to communicate between the VME, telescope, and array levels. We also discuss the performance of the data acquisition for array operations.

  10. LEGS data acquisition facility

    The data acquisition facility for the LEGS medium energy photonuclear beam line is composed of an auxiliary crate controller (ACC) acting as a front-end processor, loosely coupled to a time-sharing host computer based on a UNIX-like environment. The ACC services all real-time demands in the CAMAC crate: it responds to LAMs generated by data acquisition modules, to keyboard commands, and it refreshes the graphics display at frequent intervals. The host processor is needed only for printing histograms and recording event buffers on magnetic tape. The host also provides the environment for software development. The CAMAC crate is interfaced by a VERSAbus CAMAC branch driver

This paper describes the hardware configuration of the system and the method of task sharing and compares results to the single processor system

  13. MDSplus data acquisition system

    MDSplus, a tree based, distributed data acquisition system, was developed in collaboration with the ZTH Group at Los Alamos National Lab and the RFX Group at CNR in Padua, Italy. It is currently in use at MIT, RFX in Padua, TCV at EPFL in Lausanne, and KBSI in South Korea. MDSplus is made up of a set of X/motif based tools for data acquisition and display, as well as diagnostic configuration and management. It is based on a hierarchical experiment description which completely describes the data acquisition and analysis tasks and contains the results from these operations. These tools were designed to operate in a distributed, client/server environment with multiple concurrent readers and writers to the data store. While usually used over a Local Area Network, these tools can be used over the Internet to provide access for remote diagnosticians and even machine operators. An interface to a relational database is provided for storage and management of processed data. IDL is used as the primary data analysis and visualization tool.

  14. Data Acquisition System

    The Data Acquisition System (DAS) is comprised of a Hewlett-Packard (HP) model 9816, Series 200 Computer System with the appropriate software to acquire, control, and archive data from a Data Acquisition/Control Unit, models HP3497A and HP3498A. The primary storage medium is an HP9153 16-megabyte hard disc. The data is backed-up on three floppy discs. One floppy disc drive is contained in the HP9153 chassis; the other two comprise an HP9122 dual disc drive. An HP82906A line printer supplies hard copy backup. A block diagram of the hardware setup is shown. The HP3497A/3498A Data Acquisition/Control Units read each input channel and transmit the raw voltage reading to the HP9816 CPU via the HPIB bus. The HP9816 converts this voltage to the appropriate engineering units using the calibration curves for the sensor being read. The HP9816 archives both the raw and processed data along with the time and the readings were taken to hard and floppy discs. The processed values and reading time are printed on the line printer. This system is designed to accommodate several types of sensors; each type is discussed in the following sections

  15. Advanced Data Acquisition Systems

    Perotti, J.

    2003-01-01

    Current and future requirements of the aerospace sensors and transducers field make it necessary for the design and development of new data acquisition devices and instrumentation systems. New designs are sought to incorporate self-health, self-calibrating, self-repair capabilities, allowing greater measurement reliability and extended calibration cycles. With the addition of power management schemes, state-of-the-art data acquisition systems allow data to be processed and presented to the users with increased efficiency and accuracy. The design architecture presented in this paper displays an innovative approach to data acquisition systems. The design incorporates: electronic health self-check, device/system self-calibration, electronics and function self-repair, failure detection and prediction, and power management (reduced power consumption). These requirements are driven by the aerospace industry need to reduce operations and maintenance costs, to accelerate processing time and to provide reliable hardware with minimum costs. The project's design architecture incorporates some commercially available components identified during the market research investigation like: Field Programmable Gate Arrays (FPGA) Programmable Analog Integrated Circuits (PAC IC) and Field Programmable Analog Arrays (FPAA); Digital Signal Processing (DSP) electronic/system control and investigation of specific characteristics found in technologies like: Electronic Component Mean Time Between Failure (MTBF); and Radiation Hardened Component Availability. There are three main sections discussed in the design architecture presented in this document. They are the following: (a) Analog Signal Module Section, (b) Digital Signal/Control Module Section and (c) Power Management Module Section. These sections are discussed in detail in the following pages. This approach to data acquisition systems has resulted in the assignment of patent rights to Kennedy Space Center under U.S. patent # 6

  16. Aircraft Data Acquisition

    Elena BALMUS

    2016-03-01

    Full Text Available The introduction of digital systems instead of analog ones has created a major separation in the aviation technology. Although the digital equipment made possible that the increasingly faster controllers take over, we should say that the real world remains essentially analogue [4]. Fly-by-wire designers attempting to control and measure the real feedback of an aircraft were forced to find a way to connect the analogue environment to their digital equipment. In order to manage the implications of this division in aviation, data optimization and comparison has been quite an important task. The interest in using data acquisition boards is being driven by the technology and design standards in the new generation of aircraft and the ongoing efforts of reducing weight and, in some cases addressing the safety risks. This paper presents a sum of technical report data from post processing and diversification of data acquisition from Arinc 429 interface on a research aircraft platform. Arinc 429 is by far the most common data bus in use on civil transport aircraft, regional jets and executive business jets today. Since its introduction on the Boeing 757/767 and Airbus aircraft in the early 1980s hardly any aircraft has been produced without the use of this data bus. It was used widely by the air transport indu

  17. Data acquisition system DAPHNE

    DAPHNE is a data acquisition system which is being created to satisfy the needs of the accelerator based experimental research program of the division in particular the one at ATLAS. It is CAMAC based with a hardware front end consisting of multiple single board processors in a Multibus cage to provide a parallel processing capability. The host computer, a VAX 750, will provide for data logging, histogram memory space, and user interaction. The first DAPHNE system is being designed and constructed for use by ATLAS and is expected to be ready by late spring, 1985

  18. Portable data acquisition system

    Lawrence Livermore National Laboratory (LLNL) has developed a Portable Data Acquisition (DAQ) System that is basically a laboratory-scale of Program Logic Control (PLC). This DAQ system can obtain signals from numerous sensors (e.g., pH, level, pressure, flow meters), open and close valves, and turn on and off pumps. The data can then be saved on a spreadsheet or displayed as a graph/indicator in real-time on a computer screen. The whole DAQ system was designed to be portable so that it could sit on a bench top during laboratory-scale treatability studies, or moved out into the field during larger studies. This DAQ system is also fairly simple to use. All that is required is some working knowledge of LabVIEW 4.1, and how to properly wire the process equipment. The DAQ system has been used during treatability studies on cesium precipitation, controlled hydrolysis of water- reactive wastes, and other waste treatment studies that enable LLNL to comply with the Federal Facility Compliance Act (FFCAct). Improved data acquisition allows the study to be better monitored, and therefore better controlled, and can be used to determine the results of the treatment study more effectively. This also contributes to the design of larger treatment processes

    Gerry Bauer

    The CMS Storage Manager System The tail-end of the CMS Data Acquisition System is the Storage Manger (SM), which collects output from the HLT and stages the data at Cessy for transfer to its ultimate home in the Tier-0 center. A SM system has been used by CMS for several years with the steadily evolving software within the XDAQ framework, but until relatively recently, only with provisional hardware. The SM is well known to much of the collaboration through the ‘MiniDAQ’ system, which served as the central DAQ system in 2007, and lives on in 2008 for dedicated sub-detector commissioning. Since March of 2008 a first phase of the final hardware was commissioned and used in CMS Global Runs. The system originally planned for 2008 aimed at recording ~1MB events at a few hundred Hz. The building blocks to achieve this are based on Nexsan's SATABeast storage array - a device  housing up to 40 disks of 1TB each, and possessing two controllers each capable of almost 200 MB/sec throughput....

    In this report, the authors discuss a data acquisition system, KENSnet, which is newly introduced to the KENS facility. The criteria for the data acquisition system was about 1 MIPS for CPU speed and 150 Mbytes for storage capacity for a computer per spectrometer. VAX computers were chosen with their propreitary operating system, VMS. The Vax computers are connected by a DECnet network mediated by Ethernet. Front-end computers, Apple Macintosh Plus and Macintosh II, were chosen for their user-friendly manipulation and intelligence. New CAMAC-based data acquisition electronics were developed. The data acquisition control program (ICP) and the general data analysis program (Genie) were both developed at ISIS and have been installed. 2 refs., 3 figs., 1 tab

  2. Electronics and data acquisition

    High energy physics detectors span a wide range of applications with greatly differing requirements. Although the detector configurations are very different, the application of only a few basic signal acquisition principles is required. The LHC required novel designs, but built on a wide range of previous developments that had been completed for other experiments. The high luminosity drove up the event rates, but multiple interactions per bunch crossing also made occupancy a major challenge. The large scale of detector subsystems imposed efficient designs where cost was a major consideration, but the difficulty of accessing detector components added reliability to the list of more severe requirements. Radiation damage, especially in the inner detectors, added additional crucial constraints. This paper will discuss electronics requirements, the configurations of major LHC detectors, and the readout systems. After a discussion of front-end implementations and radiation effects, systems with extreme performance requirements are described in more detail, i.e. silicon strip and pixel systems.

    Frans Meijers

    The installation of the 50 kHz DAQ/HLT system has been completed during 2008. The equipment consists of the full detector readout, 8 DAQ slices with a 1 Tbit/s event building capacity, an event filter to run the High Level Trigger (HLT) comprising 720 8-core PCs, and a 16-node storage manager system allowing a write throughput up to 2 GByte/s and a total capacity of 300 TByte. The 50 kHz DAQ system has been commissioned and has been put into service for global cosmics and commissioning data taking. During CRAFT, data was taken with the full detector at ~600 Hz cosmic trigger rate. Often an additional 20 kHz of random triggers were mixed, which were pre-scaled for storage.  The random rate has been increased to ~90 kHz for the commissioning and cosmics runs in 2009, which included all detectors except tracker. The DAQ system is used, in addition to global data taking, for further commissioning and testing of the central DAQ. To this end data emulators are used at the front-end of the central DAQ (in...

    The 200 m meteorological tower of the Karlsruhe Nuclear Research Center has been equipped with 45 instruments measuring the meteorological parameters near the ground level. Frequent inquiry of the instruments implies data acquisition with on-line data reduction. This task is fulfilled by some peripheral units controlled by a PDP-8/I. This report presents details of the hardware configuration and a short description of the software configuration of the meteorological data acquisition system. The report also serves as an instruction for maintenance and repair work to be carried out at the system. (orig.)

  10. Thermochemical data acquisition

    Thermochemical data are required for specific fission product and reactor materials compounds in order to quantify the consequences of a severe accident within a light water reactor. Approximately 40 important compounds/systems have been identified for study for which thermodynamic data did not exist or were inadequate. Work is described on the analysis of approximately half of these systems. Experimental studies have been undertaken to determine the thermodynamic quantities of the following compounds: Cs2MoO4 (g), CsBO2 (g), Cs2RuO4 (c), Cs2RuO4 (g), Cs2MnO4(c), Cs2CrO4 (g), Cs2TeO3 (g), Cs2TeO3 (g), Cs2Te (g), InI (g), InI3 (g), In2I6 (g), In2Te (g), Cd (OH) 2 (c), Cd (OH) 2 (g), TeO (OH) 2 (g), CdI2 (g), Cd2I4 (g), Cs2CdI4 (c), CsCdI3 (g), Cs2CdI4 (g), Cs3 PO4 (c) and Cd-In-Ag. Critical assessments have been made on the following systems: In-I, In-Te, Cd-I, Sr-B-O and Ba-B-O. The thermodynamic quantities of these compounds have been calculated over the temperature range from 298 to 3000 K. (author)

    Attila Racz

    DAQ/On-Line Computing installation status After the installation and commissioning of the DAQ underground elements in 2006 and the first months of 2007, all the efforts are now directed to the installation and commissioning of the On-Line Computing farm (OLC) located on the first floor of SCX5 building at the CMS experimental site. In summer 2007, 640 Readout Unit servers (RUs) have been installed and commissioned along with 160 servers providing general services for the users (DCS, database, RCMS, data storage, etc). Since the global run of November 2007, the event fragments are assembled and processed by the OLC. Thanks to the flexibility of the trapezoidal event builder, some RUs are acting as Filter Units (FUs) and hence provide the full processing chain with a single type of server. With this temporary configuration, all FEDs can be readout at a few kHz. Since the March 08 global run, events are stored on the storage manager SAN in the OLC, and subsequently transferred over the dedicated CDR link (2 x...

  18. WRATS Integrated Data Acquisition System

    Piatak, David J.

    2008-01-01

    The Wing and Rotor Aeroelastic Test System (WRATS) data acquisition system (DAS) is a 64-channel data acquisition display and analysis system specifically designed for use with the WRATS 1/5-scale V-22 tiltrotor model of the Bell Osprey. It is the primary data acquisition system for experimental aeroelastic testing of the WRATS model for the purpose of characterizing the aeromechanical and aeroelastic stability of prototype tiltrotor configurations. The WRATS DAS was also used during aeroelastic testing of Bell Helicopter Textron s Quad-Tiltrotor (QTR) design concept, a test which received international attention. The LabVIEW-based design is portable and capable of powering and conditioning over 64 channels of dynamic data at sampling rates up to 1,000 Hz. The system includes a 60-second circular data archive, an integrated model swashplate excitation system, a moving block damping application for calculation of whirl flutter mode subcritical damping, a loads and safety monitor, a pilot-control console display, data analysis capabilities, and instrumentation calibration functions. Three networked computers running custom-designed LabVIEW software acquire data through National Instruments data acquisition hardware. The aeroelastic model (see figure) was tested with the DAS at two facilities at NASA Langley, the Transonic Dynamics Tunnel (TDT) and the Rotorcraft Hover Test Facility (RHTF). Because of the need for seamless transition between testing at these facilities, DAS is portable. The software is capable of harmonic analysis of periodic time history data, Fast Fourier Transform calculations, power spectral density calculations, and on-line calibration of test instrumentation. DAS has a circular buffer archive to ensure critical data is not lost in event of model failure/incident, as well as a sample-and-hold capability for phase-correct time history data.

    In this paper we describe the design, the construction, the commissioning and the operation of the Data Acquisition (DAQ) and Experiment Control Systems (ECS) of the ALICE experiment at the CERN Large Hadron Collider (LHC). The DAQ and the ECS are the systems used respectively for the acquisition of all physics data and for the overall control of the experiment. They are two computing systems made of hundreds of PCs and data storage units interconnected via two networks. The collection of experimental data from the detectors is performed by several hundreds of high-speed optical links. We describe in detail the design considerations for these systems handling the extreme data throughput resulting from central lead ions collisions at LHC energy. The implementation of the resulting requirements into hardware (custom optical links and commercial computing equipment), infrastructure (racks, cooling, power distribution, control room), and software led to many innovative solutions which are described together with ...

    Hons, Zdenek

    2016-01-01

    DANSS (Detector of the reactor AntiNeutrino based on Solid Scintillator) is a project aiming to measure a spectrum of reactor antineutrinos using inverse beta decay (IBD) in a plastic scintillator. The detector is located close to an industrial nuclear reactor core and is covered by passive and active shielding. It is expected to detect about 15000 IBD events per day. Light from the detector is sensed by PMT and SiPM. This paper describes the data acquisition system used for data readout of the 50 detector PMT channels and active shielding. Theoretical approach to the data acquisition is described and two possible solutions using QDCs and digitizers are discussed. Also described are the results of the DAQ performance during routine data taking operation of the detector.

  1. COLDEX New Data Acquisition Framework

    Grech, Christian

    2015-01-01

    COLDEX (COLD bore EXperiment) is an experiment of the TE-VSC group installed in the Super Proton Synchrotron (SPS) which mimics a LHC type cryogenic vacuum system. In the framework of the High Luminosity upgrade of the LHC (HL-LHC project), COLDEX has been recommissioned in 2014 in order to validate carbon coatings performances at cryogenic temperature with LHC type beams. To achieve this mission, a data acquisition system is needed to retrieve and store information from the different experiment’s systems (vacuum, cryogenics, controls, safety) and perform specific calculations. This work aimed to completely redesign, implement, test and operate a brand new data acquisition framework based on communication with the experiment’s PLCs for the devices potentially available over network. The communication protocol to the PLCs is based on data retrieval both from CERN middleware infrastructures (CMW, JAPC) and on a novel open source Simatic S7 data exchange package over TCP/IP (libnodave).

  3. 4 NCIC Data Acquisition Guide

    U.S. Geological Survey

    1979-01-01

    The National Cartographic Information Center (NCIC) is the information branch of the National Mapping Program. NCIC gathers descriptions of cartographic products held by Federal, State and local agencies, and private companies. Computerized information systems are used to edit, store, and distribute these descriptions.

  7. Data acquisition for sensor systems

    Taylor, H Rosemary

    1997-01-01

    'Data acquisition' is concerned with taking one or more analogue signals and converting them to digital form with sufficient accu­ racy and speed to be ready for processing by a computer. The increasing use of computers makes this an expanding field, and it is important that the conversion process is done correctly because information lost at this stage can never be regained, no matter how good the computation. The old saying - garbage in, garbage out - is very relevant to data acquisition, and so every part of the book contains a discussion of errors: where do they come from, how large are they, and what can be done to reduce them? The book aims to treat the data acquisition process in depth with less detailed chapters on the fundamental principles of measure­ ment, sensors and signal conditioning. There is also a chapter on software packages, which are becoming increasingly popular. This is such a rapidly changing topic that any review of available pro­ grams is bound to be out of date before the book re...

  8. Future data acquisition at ISIS

    Data collection techniques at ISIS are fast reaching the point where the current computer systems will no longer be able to migrate the data to long-term storage, let alone enable their analysis at a speed compatible with continuous use of the ISIS instruments. The current data acquisition electronics (DAE 1) and migration path work effectively but have a number of inherent difficulties: (1) Seven instruments are equipped with VAX computers as their Front End Minicomputers (FEM). Unfortunately these machines usually possess insufficient processor power to perform some of the more complex data reduction. This means that the raw data have necessarily to be networked to the HUB computer before analysis. (2) The size of bulk store memory is restricted to 16 Mbytes by the 24 bit address field of Multibus. (3) The DAE error detection and analysis system of FEM is crude. It is clear that the most effective method to improve on this situation is to reduce the data volume flowing between the DAE and the FEM and to provide facilities to monitor data acquisition within the DAE. For these purposes processing power must be incorporated closer to the point of data collection. It has been decided to implement processing elements within DAE 2 (the next generation of DAE) in the form of intelligent memory boards. 6 figs., 1 tab

  9. SND data acquisition system upgrade

    The data acquisition (DAQ) system of the SND detector successfully operated during four data-taking seasons (2010–2013) at the e+e− collider VEPP-2000. Currently the collider is shut down for planned reconstruction, which is expected to increase the VEPP-2000 luminosity and data flow from the SND detector electronics by up to 10 times. Since current DAQ system implementation (electronics and computer part) does not have enough reserve for selection of events in the new environment without compromising quality, there arose the need for the system upgrade. Here we report on the major SND data acquisition system upgrade which includes developing new electronics for digitization and data transfer, complete redesign of the data network, increasing of the DAQ computer farm processing capacity and making the event building process concurrent. These measures will allow us to collect data flow from the most congested detector subsystems in parallel in contrast to the current situation. We would like to discuss also the possibility to implement full software trigger solution in the future

    In this paper we describe the design, the construction, the commissioning and the operation of the Data Acquisition (DAQ) and Experiment Control Systems (ECS) of the ALICE experiment at the CERN Large Hadron Collider (LHC). The DAQ and the ECS are the systems used respectively for the acquisition of all physics data and for the overall control of the experiment. They are two computing systems made of hundreds of PCs and data storage units interconnected via two networks. The collection of experimental data from the detectors is performed by several hundreds of high-speed optical links. We describe in detail the design considerations for these systems handling the extreme data throughput resulting from central lead ions collisions at LHC energy. The implementation of the resulting requirements into hardware (custom optical links and commercial computing equipment), infrastructure (racks, cooling, power distribution, control room), and software led to many innovative solutions which are described together with a presentation of all the major components of the systems, as currently realized. We also report on the performance achieved during the first period of data taking (from 2009 to 2013) often exceeding those specified in the DAQ Technical Design Report.

    A large array of MicroVAX computers will be used for high-speed data acquisition and online filtering in the D0 experiment at Fermi National Accelerator Laboratory. We discuss new developments related to this system, in hardware and particularly in software. The new hardware includes multiported memory boards for faster and more direct input and output of event data. Most of the software development is related to the crucial role of the event filters, requiring an elaborate mechanism for control and monitoring of the FORTRAN based programs running in each of the MicroVAXes.

  14. Web-based data acquisition

    胡旭东; 俞红; 陈鹰

    2002-01-01

    The research work on Web-based long-distance data acquisition (DAQ) is valuable for application to tele-detection machine faults. With an expert system for machine fault detection, faults in a distantly located machine can be diagnosed through the internet. The distant user logs on to the expert system Web page, fills in the requirements, and starts-up the diagnose process. The system then connects to the DAQ server that is installed in the machine, samples data required for diagnoses through the internet, and sends back diagnose results. In such a long-distance system, Web-based DAQ plays an important role by automatic sampling and transferring of data through the internet. We have built an experimental data acquisition system using a National Instruments AT-MIO-16E-10 board running under Ch language environment. In this experimental example, the user can acquire data online. The principle of this experimental method is introduced in this paper. A detailed programming technique is described with an example.

  15. Classification and data acquisition with incomplete data

    Williams, David P.

    In remote-sensing applications, incomplete data can result when only a subset of sensors (e.g., radar, infrared, acoustic) are deployed at certain regions. The limitations of single sensor systems have spurred interest in employing multiple sensor modalities simultaneously. For example, in land mine detection tasks, different sensor modalities are better-suited to capture different aspects of the underlying physics of the mines. Synthetic aperture radar sensors may be better at detecting surface mines, while infrared sensors may be better at detecting buried mines. By employing multiple sensor modalities to address the detection task, the strengths of the disparate sensors can be exploited in a synergistic manner to improve performance beyond that which would be achievable with either single sensor alone. When multi-sensor approaches are employed, however, incomplete data can be manifested. If each sensor is located on a separate platform ( e.g., aircraft), each sensor may interrogate---and hence collect data over---only partially overlapping areas of land. As a result, some data points may be characterized by data (i.e., features) from only a subset of the possible sensors employed in the task. Equivalently, this scenario implies that some data points will be missing features. Increasing focus in the future on using---and fusing data from---multiple sensors will make such incomplete-data problems commonplace. In many applications involving incomplete data, it is possible to acquire the missing data at a cost. In multi-sensor remote-sensing applications, data is acquired by deploying sensors to data points. Acquiring data is usually an expensive, time-consuming task, a fact that necessitates an intelligent data acquisition process. Incomplete data is not limited to remote-sensing applications, but rather, can arise in virtually any data set. In this dissertation, we address the general problem of classification when faced with incomplete data. We also address the

    DEAP-3600 is a dark matter experiment using liquid argon to detect Weakly Interacting Massive Particles (WIMPs). The DEAP-3600 Data Acquisition (DAQ) has been built using a combination of commercial and custom electronics, organized using the MIDAS framework. The DAQ system needs to suppress a high rate of background events from 39Ar beta decays. This suppression is implemented using a combination of online firmware and software-based event filtering. We will report on progress commissioning the DAQ system, as well as the development of the web-based user interface.

  17. The NIFFTE Data Acquisition System

    Qu, Hai; Niffte Collaboration

    2011-10-01

    The Neutron Induced Fission Fragment Tracking Experiment (NIFFTE) will employ a novel, high granularity, pressurized Time Projection Chamber to measure fission cross-sections of the major actinides to high precision over a wide incident neutron energy range. These results will improve nuclear data accuracy and benefit the fuel cycle in the future. The NIFFTE data acquisition system (DAQ) has been designed and implemented on the prototype TPC. Lessons learned from engineering runs have been incorporated into some design changes that are being implemented before the next run cycle. A fully instrumented sextant of EtherDAQ cards (16 sectors, 496 channels) will be used for the next run cycle. The Maximum Integrated Data Acquisition System (MIDAS) has been chosen and customized to configure and run the experiment. It also meets the requirement for remote control and monitoring of the system. The integration of the MIDAS online database with the persistent PostgreSQL database has been implemented for experiment usage. The detailed design and current status of the DAQ system will be presented.

  18. Data acquisition system for MEGHA

    A multi-channel data acquisition system has been commissioned for the Charissa 'MEGHA' detector array. It is designed to read multiparameter events where there are many potential channels (320) but where only a fraction of these are active in any typical event. Custom-built pre- and main amplifiers process the amplitude (energy) signal from each detector and the system records both amplitude and time of arrival for each signal within an event. The signal amplitude is converted to time using the standard Wilkinson technique and then combined with its time of arrival into a single time trace. These traces are converted by multi-hit TDCs, which only convert the active channels and thus reduce the processing load. Additional custom-built CAMAC modules organise the TDC output into a suitable form for storage and transmission to a network of processor terminals over standard ethernet. This paper presents a description of the data acquisition system from preamplifier through to final storage in a VME-based system and subsequent distribution to a network of Sun terminals over ethernet. The system performance is illustrated with results from heavy-ion elastic scattering recorded with position sensitive strip detectors

  19. CEBAF Distributed Data Acquisition System

    Allison, Trent

    2005-01-01

    There are thousands of signals distributed throughout Jefferson Lab's Continuous Electron Beam Accelerator Facility (CEBAF) that are useful for troubleshooting and identifying instabilities. Many of these signals are only available locally or monitored by systems with small bandwidths that cannot identify fast transients. The Distributed Data Acquisition (Dist DAQ) system will sample and record these signals simultaneously at rates up to 40 Msps. Its primary function will be to provide waveform records from signals throughout CEBAF to the Experimental Physics and Industrial Control System (EPICS). The waveforms will be collected after the occurrence of an event trigger. These triggers will be derived from signals such as periodic timers or accelerator faults. The waveform data can then be processed to quickly identify beam transport issues, thus reducing down time and increasing CEBAF performance. The Dist DAQ system will be comprised of multiple standalone chassis distributed throughout CEBAF. They will be i...

  1. Data acquisition and control network

    We have participated in the construction of the CELLO detector on the PETRA e+e- Collider in Hamburg in order to test some of the current high energy physics theories. Some 60.000 channels collecting the detector informations are connected to the main computer through the CAMAC acquisition system and specialized ROMULUS subsystems. Each of these subsystems is monitored by its dedicated microprocessor using a CAMAC dataway spy module. All these microprocessors are connected to the main computer through a ''STAR'' type network. Data are read out by the main computer (PDP11-45) and concentrated in a circular type buffer. They are then filtered and transfered to a PDP11-55, also in the network, for storing

    2002-01-01

    A fully pipelined and massively parallel data acquisition system has been developed for the COMPASS experiment at CERN. The main requirements are to read 250000 detector channels at a trigger rate of up to 100 kHz. Such high rates are only possible when using a hit selection mechanism on the front-end combined with dead-time free readout. For this purpose, a time-to-digital converter (TDC) chip has been developed and is used for all time measurement applications in COMPASS. Distributed, field programmable gate array (FPGA)-based readout-driver modules handle parallel front-end initialization, synchronous trigger and control-signal distribution, and local event building at a processing speed of 160 Mbyte/s. Each of the 160 readout-driver modules connects to 16 front-end boards through independent twisted pair cables (CAT 7, 600 MHz) or optical fibers using an industrial (ESCON), self synchronizing link at 40 Mbyte/s. Automatic configuration through unique module and link identification ensures the flexibility ...

  5. Multi spectral scaling data acquisition system

    In nuclear spectroscopy applications, it is often desired to acquire data at high rate with high resolution. With the availability of low cost computers, it is possible to make a powerful data acquisition system with minimum hardware and software development, by designing a PC plug-in acquisition board. But in using the PC processor for data acquisition, the PC can not be used as a multitasking node. Keeping this in view, PC plug-in acquisition boards with on-board processor find tremendous applications. Transputer based data acquisition board has been designed which can be configured as a high count rate pulse height MCA or as a Multi Spectral Scaler. Multi Spectral Scaling (MSS) is a new technique, in which multiple spectra are acquired in small time frames and are then analyzed. This paper describes the details of this multi spectral scaling data acquisition system. 2 figs

  6. Electronic Flash In Data Acquisition

    Miller, C. E.

    1982-02-01

    Photographic acquisition of data often may be simplified, or the data quality improved upon by employing electronic flash sources with traditional equipment or techniques. The relatively short flash duration compared to movie camera shutters, or to the long integration time of video camera provides improved spatial resolution through blur reduction, particularly important as image movement becomes a significant fraction of film format dimension. Greater accuracy typically is achieved in velocity and acceleration determinations by using a stroboscopic light source rather than a movie camera frame-rate control as a time standard. Electrical efficiency often is an important advantage of electronic flash sources since almost any necessary light level for exposure may be produced, yet the source typically is "off" most of the time. Various synchronization techniques greatly expand the precise control of exposure. Biomechanical and sports equipment studies may involve velocities up to 200 feet-per-second, and often will have associated very rapid actions of interest. The need for brief exposures increases H.s one "ZOOMS in on the action." In golf, for example, the swing may be examined using 100 microsecond (Us) flashes at rates of 60 or 120 flashes-per-second (FPS). Accurate determination of linear and rotational velocity of the ball requires 10 Us flashes at 500-1,000 FPS, while sub-Us flashes at 20,000-50,000 FPS are required to resolve the interaction of the ball and the club, head. Some seldom. used techniques involving streak photography are described, with enhanced results obtained by combining strobe with the usual continuous light source. The combination of strobe and a fast electro-mechanical shutter is considered for Us photography under daylight conditions.

    Sinquin, Jean-Marc; Sorribas, Jordi; Diviacco, Paolo; Vandenberghe, Thomas; Munoz, Raquel; Garcia, Oscar

    2016-04-01

    The EU FP7 Projects Eurofleets and Eurofleets2 are an European wide alliance of marine research centers that aim to share their research vessels, to improve information sharing on planned, current and completed cruises, on details of ocean-going research vessels and specialized equipment, and to durably improve cost-effectiveness of cruises. Within this context logging of information on how, when and where anything happens on board of the vessel is crucial information for data users in a later stage. This forms a primordial step in the process of data quality control as it could assist in the understanding of anomalies and unexpected trends recorded in the acquired data sets. In this way completeness of the metadata is improved as it is recorded accurately at the origin of the measurement. The collection of this crucial information has been done in very different ways, using different procedures, formats and pieces of software in the context of the European Research Fleet. At the time that the Eurofleets project started, every institution and country had adopted different strategies and approaches, which complicated the task of users that need to log general purpose information and events on-board whenever they access a different platform loosing the opportunity to produce this valuable metadata on-board. Among the many goals the Eurofleets project has, a very important task is the development of an "event log software" called EARS (Eurofleets Automatic Reporting System) that enables scientists and operators to record what happens during a survey. EARS will allow users to fill, in a standardized way, the gap existing at the moment in metadata description that only very seldom links data with its history. Events generated automatically by acquisition instruments will also be handled, enhancing the granularity and precision of the event annotation. The adoption of a common procedure to log survey events and a common terminology to describe them is crucial to provide

    The proposed new data acquisition system architecture takes event fragments off a detector over fiber optics and to a parallel event building switch. The parallel event building switch concept, taken from the telephone communications industry, along with expected technology improvements in fiber-optic data transmission speeds over the next few years, should allow data acquisition system rates to increase dramatically and exceed those rates needed for the SSC. This report briefly describes the switch architecture and fiber optics for a SSC data acquisition system.

  3. A data acquisition backbone core library

    For the new experiments at FAIR new concepts of data acquisition systems have to be developed like the distribution of self-triggered, time stamped data streams over high performance networks for event building. The data acquisition backbone core (DABC) is a general purpose software framework designed for the implementation of such data acquisition systems. It provides the event building over networks like InfiniBand or Gigabit Ethernet. All kinds of data channels (front-end systems) are supported by program plug-ins into functional components of DABC like data input, combiner, scheduler, event builder, analysis and storage components. Commands and parameters of DABC and its application plug-ins are published by DIM servers. A Java based Graphical User Interface provides the dynamic control and visualization of these components. Application specific GUIs can be added. After a testing phase, DABC can be used to develop high performance data acquisition systems. Besides that DABC will be used for the implementation of various test beds needed for the final design of data acquisition systems at FAIR like detector tests, readout components test, and data flow investigations

  10. Data acquisition for high energy physics experiments

    The general scope of Data Acquisition Systems range from the feedthroughs on the actual detectors to the storage racks for the data recording media. The systems are concerned with the conversion of interesting, volatile signals usually to a stable, digitized format. The problems involved are interesting because of the boundary conditions: engineering, economics, required resolution and range, rates, radiation damage, and physical size available for the components. Systems that will be considered here are limited to those for e+e- and hadronic colliding beam problems. Component tasks of a Data Acquisition System are preamplification and signal conditioning, digitization, sparsification, data correction, data reduction, and data recording. Implementation of these tasks require considerations for buffering of the data, multiplexing of the data paths, and triggering systems to control the Data Acquisition System. These lecture develop a conceptual understanding of the building blocks required for these systems and their relationships to each other in real systems. The approach is pedagogic and a variety of data acquisition issues are introduced. An SLD is used for illustration an SSC detector is briefly considered

  15. Thermochemical data acquisition - Part II

    The study was a joint effort of the four laboratories AEA Harwell, Winfrith, ECN Petten and the Free University of Brussels. Thermochemical data have been determined for a number of fission product and reactor material compounds. Critical assessments have also been made of the available thermochemical data on a number of systems. These data complement the results from similar studies conducted in 1990 (see EUR 14004 EN), and can be used in the appropriate computer codes for calculations of the speciation and transport properties of the fission products during a severe reactor accident. The work load was subdivided as follows: experimental studies of Harwell, Winfrith and Petten (Chapters 1 to 7) have focused on the vaporization of tellurium dioxide, caesium ruthenate, strontium and barium borate, indium hydroxide, caesium telluride, caesium phosphate, caesium hydroxide and caesium iodate and on the thermodynamic properties of the condensed phases Cdl2, Cs2Cdl4, Cs2Si4O9, Cs2ZrO3, SrB4O7, and Ba3B2O6. Critical evaluations have been made of a number of tellurides of importance in severe accident assessments, and analysis have been made of the Fe-Te, Ni-Te and Cr-Te systems. Tables of thermodynamic properties over the temperature range 298.15 to 3 000 K are given. The data are believed to predict the fission product species and their transport in case of severe reactor accidents with greater confidence. The Free University of Brussels (Chapter 8) carried out thermodynamic studies of the systems Cs-Te, In-Te and Cs-In-Te using the mass spectrometric Knudsen cell method. The gas phases formed between 800 and 1 300 K were investigated and the partial pressure and relative ionization cross-sections of the system components were determined

  19. Effective GPR Data Acquisition and Imaging

    Sato, M.

    2014-12-01

    We have demonstrated that dense GPR data acquisition typically antenna step increment less than 1/10 wave length can provide clear 3-dimeantiona subsurface images, and we created 3DGPR images. Now we are interested in developing GPR survey methodologies which required less data acquisition time. In order to speed up the data acquisition, we are studying efficient antenna positioning for GPR survey and 3-D imaging algorithm. For example, we have developed a dual sensor "ALIS", which combines GPR with metal detector (Electromagnetic Induction sensor) for humanitarian demining, which acquires GPR data by hand scanning. ALIS is a pulse radar system, which has a frequency range 0.5-3GHz.The sensor position tracking system has accuracy about a few cm, and the data spacing is typically more than a few cm, but it can visualize the mines, which has a diameter about 8cm. 2 systems of ALIS have been deployed by Cambodian Mine Action Center (CMAC) in mine fields in Cambodia since 2009 and have detected more than 80 buried land mines. We are now developing signal processing for an array type GPR "Yakumo". Yakumo is a SFCW radar system which is a multi-static radar, consisted of 8 transmitter antennas and 8 receiver antennas. We have demonstrated that the multi-static data acquisition is not only effective in data acquisition, but at the same time, it can increase the quality of GPR images. Archaeological survey by Yakumo in large areas, which are more than 100m by 100m have been conducted, for promoting recovery from Tsunami attacked East Japan in March 2011. With a conventional GPR system, we are developing an interpolation method of radar signals, and demonstrated that it can increase the quality of the radar images, without increasing the data acquisition points. When we acquire one dimensional GPR profile along a survey line, we can acquire relatively high density data sets. However, when we need to relocate the data sets along a "virtual" survey line, for example a

  4. A Lossless Network for Data Acquisition

    AUTHOR|(SzGeCERN)698154; The ATLAS collaboration; Lehmann Miotto, Giovanna

    2016-01-01

    The planned upgrades of the experiments at the Large Hadron Collider at CERN will require higher bandwidth networks for their data acquisition systems. The network congestion problem arising from the bursty many-to-one communication pattern, typical for these systems, will become more demanding. It is questionable whether commodity TCP/IP and Ethernet technologies in their current form will be still able to effectively adapt to the bursty traffic without losing packets due to the scarcity of buffers in the networking hardware. We continue our study of the idea of lossless switching in software running on commercial-off-the-shelf servers for data acquisition systems, using the ATLAS experiment as a case study. The flexibility of design in software, performance of modern computer platforms, and buffering capabilities constrained solely by the amount of DRAM memory are a strong basis for building a network dedicated to data acquisition with commodity hardware, which can provide reliable transport in congested co...

    Full Text Available Television broadcasting over IP networks (IPTV is one of a number of network applications that are except of media distribution also interested in data acquisition from group of information resources of variable size. IP-TV uses Real-time Transport Protocol (RTP protocol for media streaming and RTP Control Protocol (RTCP protocol for session quality feedback. Other applications, for example sensor networks, have data acquisition as the main task. Current solutions have mostly problem with scalability - how to collect and process information from large amount of end nodes quickly and effectively? The article deals with optimization of hierarchical system of data acquisition. Problem is mathematically described, delay minima are searched and results are proved by simulations.

  6. PC based 8-parameter data acquisition system

    Multiparameter data acquisition (MPA) systems which analyse nuclear events with respect to more than one property of the event are essential tools for the study of some complex nuclear phenomena requiring analysis of time coincident spectra. For better throughput and accuracy each parameter is digitized by its own ADC. A stand alone low cost IBM PC based 8-parameter data acquisition system developed by the authors makes use of Address Recording technique for acquiring data from eight 12 bit ADC's in the PC Memory. Two memory buffers in the PC memory are used in ping-pong fashion so that data acquisition in one bank and dumping of data onto PC disk from the other bank can proceed simultaneously. Data is acquired in the PC memory through DMA mode for realising high throughput and hardware interrupt is used for switching banks for data acquisition. A comprehensive software package developed in Turbo-Pascal offers a set of menu-driven interactive commands to the user for setting-up system parameters and control of the system. The system is to be used with pelletron accelerator. (author). 5 figs

    1997-09-01

    The control and data acquisition systems for Atlas will use a large degree of decentralization. By distributing control points close to the systems being controlled, the authors expect to simplify the task of isolating electronic systems from the large expected EMI pulses, allow connection of the various parts of the system by high-level fiber-optic networks, allow a simple configuration of the control and data acquisition screen rooms, and simplify the software efforts through the resulting modularization. The Atlas control system must control capacitor charging, machine and diagnostic timing and triggering, marx module diagnostics, vacuum systems, gas handling for railgaps, safety interlocks, and oil handling. Many of these tasks will be performed by industrial-style programmable logic controllers (PLCs). Each of 38 Marx bank maintenance units will have a control and diagnostic package which will monitor both charging and discharging current and railgap trigger timing. An unusual feature of digitizers to record each Marx module`s output waveform, plus nanosecond resolution time interval meters to record the firing time of each railgap. The machine data acquisition system for Atlas will be built around an SQL database, use National Instruments LabVIEW software to control data acquisition instruments and provide links for a variety of experimentalists` data analysis packages. World Wide Web access will provide an interface through which users can monitor experimental data and machine status.

  9. An original approach to data acquisition CHADAC

    CERN. Geneva

    1981-01-01

    Many labs try to boost existing data acquisition systems by inserting high performance intelligent devices in the important nodes of the system's structure. This strategy finds its limits in the system's architecture. The CHADAC project proposes a simple and efficient solution to this problem, using a multiprocessor modular architecture. CHADAC main features are: parallel acquisition of data; CHADAC is fast, it dedicates one processor per branch and each processor can read and store one 16 bit word in 800 ns; original structure; each processor can work in its own private memory, in its own shared memory (double access) and in the shared memory of any other processor. Simple and fast communications between processors are also provided by local DMAs; flexibility; each processor is autonomous and may be used as an independent acquisition system for a branch, by connecting local peripherals to it. Adjunction of fast trigger logic is possible. By its architecture and performances, CHADAC is designed to provide a g...

  17. The MAST data acquisition system - system architecture

    A new data acquisition (DA) system has been developed for the MAST experiment at Culham. It has also been implemented on the COMPASS experiment as a replacement for the old PDP-11 based data acquisition system and as a test bed for MAST. The DA system is distributed across a number of computers with a DA process for each distinct diagnostic system. An object-orientated approach is taken to the control and readout of each device in the system. It is designed to be independent of the hardware interfaces used on each diagnostic. The system is flexible enough to cope with diagnostics ranging from those involving simple time evolving signals to complex spectrometers, and will incorporate a new high speed distributed timing system. This system is also being considered as the interface to the real time Plasma Control system on MAST. A distributed scheduling system is used to co-ordinate the activity of each DA process with the Central Control system for each experiment. This paper describes the architecture of this data acquisition system with particular emphasis on the core of the data acquisition system. Aspects of distributed implementation of the system on real diagnostics are discussed in a companion paper

  19. On Shaft Data Acquisition System (OSDAS)

    Pedings, Marc; DeHart, Shawn; Formby, Jason; Naumann, Charles

    2012-01-01

    On Shaft Data Acquisition System (OSDAS) is a rugged, compact, multiple-channel data acquisition computer system that is designed to record data from instrumentation while operating under extreme rotational centrifugal or gravitational acceleration forces. This system, which was developed for the Heritage Fuel Air Turbine Test (HFATT) program, addresses the problem of recording multiple channels of high-sample-rate data on most any rotating test article by mounting the entire acquisition computer onboard with the turbine test article. With the limited availability of slip ring wires for power and communication, OSDAS utilizes its own resources to provide independent power and amplification for each instrument. Since OSDAS utilizes standard PC technology as well as shared code interfaces with the next-generation, real-time health monitoring system (SPARTAA Scalable Parallel Architecture for Real Time Analysis and Acquisition), this system could be expanded beyond its current capabilities, such as providing advanced health monitoring capabilities for the test article. High-conductor-count slip rings are expensive to purchase and maintain, yet only provide a limited number of conductors for routing instrumentation off the article and to a stationary data acquisition system. In addition to being limited to a small number of instruments, slip rings are prone to wear quickly, and introduce noise and other undesirable characteristics to the signal data. This led to the development of a system capable of recording high-density instrumentation, at high sample rates, on the test article itself, all while under extreme rotational stress. OSDAS is a fully functional PC-based system with 48 channels of 24-bit, high-sample-rate input channels, phase synchronized, with an onboard storage capacity of over 1/2-terabyte of solid-state storage. This recording system takes a novel approach to the problem of recording multiple channels of instrumentation, integrated with the test

    2011-05-01

    The Data Acquisition System for the CDMS II dark matter experiment was designed and built when the experiment moved to its new underground installation at the Soudan Lab. The combination of remote operation and increased data load necessitated a completely new design. Elements of the original LabView system remained as stand-alone diagnostic programs, but the main data processing moved to a VME-based system with custom electronics for signal conditioning, trigger formation and buffering. The data rate was increased 100-fold and the automated cryogenic system was linked to the data acquisition. A modular server framework with associated user interfaces was implemented in Java to allow control and monitoring of the entire experiment remotely.

    1999-01-01

    The BaBar experiment at the Stanford Linear Accelerator Center is designed to perform a search for CP violation by ana-lyzing the decays of a very large sample of B and B(Bar) mesons produced at the high luminosity PEP-II accelerator. The data acquisition system must cope with a sustained high event rate, while supporting real time feature extraction and data compression with minimal dead time. The BaBar data acquisition system is based around a common VME interface to the electronics read-out of the separate detec-tor subsystems. Data from the front end electronics is read into commercial VME processors via a custom "Personality Card" and PCI interface. The commercial CPUs run the Tornado operating system to provide a platform for detector subsystem code to perform the necessary data processing. The data is read out via a non-blocking network switch to a farm of commercial UNIX processors. The current implementation of the BaBar data acquisition sys-tem has been shown to sustain a Level 1 trigger rate of 1.3...

  11. Minicomputer evaluation for HEP data acquisition

    In 1978, a comprehensive market survey was carried out to select a computer for on-line data acquisition in a High Energy Physics particle experiment. Working parties consisting of Rutherford Laboratory personnel and UK based minicomputer users at CERN, were set up at RL and CERN to (a) compile a technical specification of the 'ideal' minicomputer for data acquisition, (b) prepare a technical questionnaire based on that specification for issue to computer manufacturers and (c) make recommendations based on the manufacturers' responses to the questionnaire. This paper outlines the criteria used in writing the specification and includes, as appendices, the specification and questionnaire as useful guidelines in any future exercise of this kind. (author)

    2015-10-01

    Neutron energy measurements can be achieved using time-of-flight (ToF) techniques. A digital data acquisition system was developed for reliable ToF measurements with subnanosecond timing resolution based on digitizers with 10 ns and 4 ns sampling periods using pulse shape analysis algorithms. A validation procedure was developed to confirm the reliability. The response of the algorithm to photomultiplier signals was studied using a specially designed experimental system based on fast plastic scintillators. The presented developments enabled digital data acquisition systems to instrument the recently developed Versatile Array of Neutron Detectors at Low-Energy (VANDLE). This research was sponsored in part by the National Nuclear Security Administration under the Stewardship Science Academic Alliances program through DOE Cooperative Agreement No. DE-FG52-08NA28552 and the Office of Nuclear Physics.

  13. Clustered data acquisition for the CMS experiment

    Powerful mainstream computing equipment and the advent of affordable multi-Gigabit communication technology allow us to tackle data acquisition problems with clusters of inexpensive computers. Such networks typically incorporate heterogeneous platforms, real-time partitions and custom devices. Therefore, one must strive for a software infrastructure that efficiently combines the nodes to a single, unified resource for the user. Overall requirements for such middleware are high efficiency and configuration flexibility. Intelligent I/O (I2O) is an industry specification that defines a uniform messaging format and executing model for processor-enabled communication equipment. Mapping this concept to a distributed computing environment and encapsulating the details of the specification into an application-programming framework allow us to provide run-time support for cluster operation. The authors give a brief overview of a framework, XDAQ that we designed and implemented at CERN for the Compact Muon Solenoid experiment's prototype data acquisition system

    AUTHOR|(SzGeCERN)698154; The ATLAS collaboration; Lehmann Miotto, Giovanna

    2016-01-01

    The bursty many-to-one communication pattern, typical for data acquisition systems, is particularly demanding for commodity TCP/IP and Ethernet technologies. We expand the study of lossless switching in software running on commercial-off-the-shelf servers, using the ATLAS experiment as a case study. In this paper we extend the popular software switch, Open vSwitch, with a dedicated, throughput-oriented buffering mechanism for data acquisition. We compare the performance under heavy congestion on typical Ethernet switches to a commodity server acting as a switch. Our results indicate that software switches with large buffers perform significantly better. Next, we evaluate the scalability of the system when building a larger topology of interconnected software switches, exploiting the integration with software-defined networking technologies. We build an IP-only leaf-spine network consisting of eight software switches running on separate physical servers as a demonstrator.

  15. Data acquisition and test system software

    Bourgeois, N.A. Jr.

    1979-03-01

    Sandia Laboratories has been assigned the task by the Base and Installation Security Systems (BISS) Program Office to develop various aspects of perimeter security systems. One part of this effort involves the development of advanced signal processing techniques to reduce the false and nuisance alarms from sensor systems while improving the probability of intrusion detection. The need existed for both data acquisition hardware and software. Also, the hardware is used to implement and test the signal processing algorithms in real time. The hardware developed for this signal processing task is the Data Acquisition and Test System (DATS). The programs developed for use on DATS are described. The descriptions are taken directly from the documentation included within the source programs themselves.

  16. An Alternative Approach to Data Acquisition Using Keyboard Emulation Technique

    Khalid, Shahrukh

    2010-01-01

    A number of data acquisition systems depend on human interface to access computer for measuring, processing and analyzing data and to prepare it for presentation and storage. Data acquisition software is installed on the computer and all intended operations are performed manually. The data acquisition software requires user intervention for operations like selection of measurement setup, acquisition and storage of data to computer. The duty of users becomes laborious if the data acquisition process lasts for a long duration and requires continuous repetition of steps. An appropriate solution to overcome such problem is to replace the physical operator with a virtual user. This software generated simulated user sits at the data acquisition process through out and automate all the intended steps of data acquisition. This paper presents a new approach for data acquisition by using keyboard emulation technique. A keyboard emulation software is developed which runs beside the main data acquisition software and act...

  19. Data Acquisition and Control Systems Laboratory

    Holland, Randy; Jensen, Scott; Burrel, Terrence; Spooner, Richard

    2002-01-01

    The Data Acquisition and Control Systems (DACS) Laboratory is a facility at Stennis Space Center that provides an off test-stand capability to develop data-acquisition and control systems for rocket-engine test stands. It is also used to train new employees in state-of-the-art systems, and provides a controlled environment for troubleshooting existing systems, as well as the ability to evaluate the application of new technologies and process improvements. With the SSC propulsion testing schedules, without the DACS Laboratory, it would have been necessary to perform most of the development work on actual test systems, thereby subjecting both the rocket-engine testing and development programs to substantial interference in the form of delays, restrictions on modifications of equipment, and potentially compromising software configuration control. The DACS Laboratory contains a versatile assortment of computer hardware and software, digital and analog electronic control and data-acquisition equipment, and standard electronic bench test equipment and tools. Recently completed Control System development and software verification projects include support to the joint NASA/Air Force Integrated Powerhead Demonstration (IPD) LOX & LH2 PreBurner and Turbopump ground testing programs. In other recent activities, the DACS Laboratory equipment and expertise have supported the off-stand operation of high-pressure control valves to correct valve leak problems prior to installation on the test stand. Future plans include expanding the Laboratory's capabilities to provide cryogenic control valve characterization prior to installation, thereby reducing test stand activation time.

  20. The ngdp framework for data acquisition systems

    The ngdp framework is intended to provide a base for the data acquisition (DAQ) system software. The ngdp's design key features are: high modularity and scalability; usage of the kernel context (particularly kernel threads) of the operating systems (OS), which allows one to avoid preemptive scheduling and unnecessary memory-to-memory copying between contexts; elimination of intermediate data storages on the media slower than the operating memory like hard disks, etc. The ngdp, having the above properties, is suitable to organize and manage data transportation and processing for needs of essentially distributed DAQ systems

  1. UA1 data-acquisition system

    The data-acquisition system of the UA1 experiment running at the CERN p anti p collider is described. The front-end electronics generates 1.6 Mbytes of raw data for each event. Parallel data-stream processors reduce the typical event data to 60,000 bytes in a time of less than 10 ms. Data are read out by Remus CAMAC branches, formated data streams being read in parallel by buffer units with multi-event storage capability. For test and monitoring, the data flow can be accessed by local processors associated with each detector subsystem. Alternatively, the over-all system can be partitioned off in a set of independent subsystems running their own data acquisition with or without a synchronous trigger. On-line functions are assured by a number of multi-task and dedicated-task 16-bit and 32-bit computers. A variety of microprocessor-based systems with autonomous capabilities control the experimental apparatus

    2015-01-01

    The primary job of an Instrumentation and Data Acquisition System (DAS) Engineer is to properly measure physical phenomenon of hardware using appropriate instrumentation and DAS equipment designed to record data during a specified test of the hardware. A DAS system includes a CPU or processor, a data storage device such as a hard drive, a data communication bus such as Universal Serial Bus, software to control the DAS system processes like calibrations, recording of data and processing of data. It also includes signal conditioning amplifiers, and certain sensors for specified measurements. My internship responsibilities have included testing and adjusting Pacific Instruments Model 9355 signal conditioning amplifiers, writing and performing checkout procedures, writing and performing calibration procedures while learning the basics of instrumentation.

  3. Data-acquisition method for multichannel systems

    An economical method is described for data acquisition from multichannel systems such as multiwire chambers in which the channels are combined into a matrix via analog adders and analog to digital converters. An implementation for a 1024-channel system was considered. The number of channels interrogated was reduced to 127. Simulation shows that the input data may be recovered completely if not more than 10 channels have operated. Recovery performance is shown as a function of number of triggered channels in a 1024-channel systems for two groups and three groups where the numbers on the curves are the tolerances in comparing the signal amplitudes in matrix projections

  8. ISON Data Acquisition and Analysis Software

    Kouprianov, Vladimir

    2013-08-01

    Since the first days of the ISON project, its success was strongly based on using advanced data analysis techniques and their implementation in software. Space debris studies and space surveillance in optical are very unique from the point of view of observation techniques and thus infer extremely specific requirements on sensor design and control and on initial data analysis, dictated mostly by fast apparent motion of space objects being studied. From the point of view of data acquisition and analysis software, this implies support for sophisticated scheduling, complex tracking, accurate timing, large fields of view, and undersampled CCD images with trailed sources. Here we present the historical outline, major goals and design concepts of the standard ISON data acquisition and analysis packages, and how they meet these requirements. Among these packages, the most important are: CHAOS telescope control system (TCS), its recent successor FORTE, and Apex II ‒ a platform for astronomical image analysis with focus on high-precision astrometry and photometry of fast-moving objects and transient phenomena. Development of these packages is supported by ISON, and they are now responsible for most of the raw data produced by the network. They are installed on nearly all sensors and are available to all participants of the ISON collaboration.

  11. Next generation PET data acquisition architectures

    New architectures for higher performance data acquisition in PET are proposed. Improvements are demanded primarily by three areas of advancing PET state of the art. First, larger detector arrays such as the Hammersmith ECAT reg-sign EXACT HR++ exceed the addressing capacity of 32 bit coincidence event words. Second, better scintillators (LSO) make depth-of-interaction (DOI) and time-of-flight (TOF) operation more practical. Third, fully optimized single photon attenuation correction requires higher rates of data collection. New technologies which enable the proposed third generation Real Time Sorter (RTS III) include: (1) 80 M byte/sec Fibre Channel RAID disk systems, (2) PowerPC on both VMEbus and PCI Local bus, and (3) quadruple interleaved DRAM controller designs. Data acquisition flexibility is enhanced through a wider 64 bit coincidence event word. PET methodology support includes DOI (6 bits), TOF (6 bits), multiple energy windows (6 bits), 512 x 512 sinogram indexes (18 bits), and 256 crystal rings (16 bits). Throughput of 10 M events/sec is expected for list-mode data collection as well as both on-line and replay histogramming. Fully efficient list-mode storage for each PET application is provided by real-time bit packing of only the active event word bits. Real-time circuits provide DOI rebinning

  12. Development of the data acquisition system 'MORAINE'

    This publication presents the software development of the data acquisition system 'MORAINE'. The distributed multiprocessor system is designed for the spectrometer SPHERE. The system consists of three VME processor modules, specialized FASTBUS modules, three personal computers (IBM PC) type networked with local Ethernet. The software is developed for three VME processor modules. It controls the reading of event fragments into VME processor modules and uses data block transfer via direct memory access, reconstructs the events, transfers data into the local network for on-line analysis and records data on external media for OFF-line analysis. The usage of the distributed computer system allows one to duplicate the efficiency of the spectrometer due to parallel reading event fragments. (author)

    2010-07-01

    In this paper we describe the data acquisition and control system of the Dark Energy Camera (DECam), which will be the primary instrument used in the Dark Energy Survey (DES). DES is a high precision multibandpath wide area survey of 5000 square degrees of the southern sky. DECam currently under construction at Fermilab will be a 3 square degree mosaic camera mounted at the prime focus of the Blanco 4m telescope at the Cerro-Tololo International Observatory (CTIO). The DECam data acquisition system (SISPI) is implemented as a distributed multi-processor system with a software architecture built on the Client-Server and Publish-Subscribe design patterns. The underlying message passing protocol is based on PYRO, a powerful distributed object technology system written entirely in Python. A distributed shared variable system was added to support exchange of telemetry data and other information between different components of the system. In this paper we discuss the SISPI infrastructure software, the image pipeline, the observer interface and quality monitoring system, and the instrument control system.

  1. Distributed radiation data acquisition system for KAPP

    Increased concern for the safety of personnel working in Nuclear Power Stations demands an efficient centralized Radiation Data Acquisition System (RADAS) to monitor different types of radiation at distributed locations of the plant. The system provides a comprehensive picture of radio-activity level distribution in the reactor building to facilitate prompt and correct decision making to take care of any emergency situation. The system is build around an industrial IBM-PC connected to remote intelligent data acquisition units using serial data communication links. To ensure high system availability and ease of maintenance the mechanical moving disk storage has been replaced by solid state memory storage (RAM Disk). Functional CRT displays have been substituted by the assembly of IBM-PC Mother Board with built-in firmware and standard TV Monitor. The computer handles a variety of processing functions which include the conversion to engineering units, checking of alarms, display/printing of plant radiation level status and system diagnostics. Intelligent terminals have been provided with graphic and text formatting capabilities. A hot standby computer connected to analog and digital inputs takes over the system functions on the failure of the host system. Modular software written in the higher level C-language runs under a standard real-time operating system Kernel. This provides for easy modification and expandability at site. Based on the experience of its commissioning at Kakrapar Power Station a new compact version is being designed for a specific application in another class of reactor. (author). 3 refs., 1 fig

  2. JDAQ, the new TEXTOR data acquisition program

    During the last years many components of the TEXTOR data management system were re-engineered. This new system was successfully used to commission and subsequently to operate TEXTOR following the installation of the Dynamic Ergodic Divertor. This paper gives an overview of one of the main re-engineered components: JDAQ, the Java (or Julich) Data AcQuisition system. JDAQ is based on the design of, and the experiences with the previous TEXTOR data acquisition systems; it was aimed to be an open, distributed and scalable system. It has almost completely been written in the JAVA object-oriented programming language, reflecting many of the code patterns known from modern software engineering. JDAQ is designed as a four-tier layered system, which can be run on a single node or distributed over a TCP/IP network. The TEXTOR operations during the last two years showed the advantage of a highly flexible, platform independent and modular development. The majority of our diagnostic subsystems have been moved to JDAQ and have been reliably operated in the TEXTOR experimental campaigns

  3. The DISTO data acquisition system at SATURNE

    The DISTO collaboration has built a large-acceptance magnetic spectrometer designed to provide broad kinematic coverage of multiparticle final states produced in pp scattering. The spectrometer has been installed in the polarized proton beam of the Saturne accelerator in Saclay to study polarization observables in the rvec pp → pK+rvec Y (Y = Λ, Σ0 or Y*) reaction and vector meson production (ψ, ω and ρ) in pp collisions. The data acquisition system is based on a VME 68030 CPU running the OS/9 operating system, housed in a single VME crate together with the CAMAC interface, the triple port ECL memories, and four RISC R3000 CPU. The digitization of signals from the detectors is made by PCOS III and FERA front-end electronics. Data of several events belonging to a single Saturne extraction are stored in VME triple-port ECL memories using a hardwired fast sequencer. The buffer, optionally filtered by the RISC R3000 CPU, is recorded on a DLT cassette by DAQ CPU using the on-board SCSI interface during the acceleration cycle. Two UNIX workstations are connected to the VME CPUs through a fast parallel bus and the Local Area Network. They analyze a subset of events for on-line monitoring. The data acquisition system is able to read and record 3,500 ev/burst in the present configuration with a dead time of 15%

  4. Data acquisition and control using ETHERNET

    We have developed a distributed computer control system to monitor and control a linear accelerator. This system consists of two PDP-11s and eight LSI 11/23s linked together with ETHERNET. The higher level systems (control consoles, etc.) use the RSX11M operating system, whereas the data acquisition and control is performed using the RSX11S operating system downline loaded from a central host computer. Locally written ETHERNET drivers are used to reduce the CPU overhead and therefore improve system response. The ETHERNET system permits remote file access by means of operator or program interaction, as well as supporting downline system loading. Control-system functions supported are supervisory control, closed-loop control, data monitoring, and data recording. 4 refs., 2 figs., 1 tab

  5. The RD13 data acquisition system

    The RD13 project was originally approved in April 1991 for the study of an LHC oriented data taking system and is now nearing the completion of its third phase of activities. The guiding objectives of the project include the construction of a scalable DAQ framework capable of evolving with detector requirements, the use of a Real-Time UNIX operating system with multiprocessor support, the evaluation and use of commercial products for all aspects of software production and a software engineering approach to software design and implementation. Special attention is also given to the modelling and simulation of full architecture solutions and their demonstration via small scale setups based on different technologies. To assess the viability of RD13 a fully operational data acquisition system fulfilling the initial requirements and based on the selected components has been successfully used as a data taking system of LHC detector prototypes that present interesting and challenging readout problems

    Powerful mainstream computing equipment and the advent of affordable multi-Gigabit communication technology allow us to tackle data acquisition problems with clusters of inexpensive computers.Such networks typically incorporate heterogeneous plat forms,real-time partitions and custom devices.Therefore,one must strive for a software infrastructure that efficiently combines the nodes to a single,unified resource for the user,Overall requirements for such middleware are high efficiency and configuration flexibility. Intelligent I/O(I2O) is an industry specification that defines a unifrom messaging format and executing model for processor-enabled communication equipment.Mapping this concept to a distribulted computing environment and encapsulating the details of the specification into an application-programming framework allow us to provide run-time support for cluster operation.This paper gives a brief overview of a framework.XDAQ that we designed and implemented at CERN for the Compact Muon Solenoid experiment's prototype data acquisition system.

    Traditional radioxenon measurements have been done by ground based fixed systems, however in recent years there has been an increased need for systems capable of quick deployment or even complete mobility. Using the Pixie-4 data acquisition (DAQ) system can help reduce the electronics footprint of both current systems, like the radioxenon Radionuclide Laboratory 16 (RL-16) and the Swedish Automatic Unit for Noble Gas Acquisition (SAUNA), as well as future systems. Pacific Northwest National Laboratory (PNNL) has developed a Linux based Nyx graphical user interface (GUI) for Pixie-4 cards. The Nyx software can be installed on various Linux platforms and is written in C++. This software offers a rich user interface for configuring and operating the Pixie4 card and PNNL designed high voltage (HV) cards. Nyx allows one to quickly get a nuclear detector operational by maintaining the core diagnostic features built into the Pixie-4 cards. First, Nyx maintains the multitude of adjustable parameters accessible in the Pixie-4 cards, which allows one to customize settings to take full advantage of a particular detector. Nyx also maintains an oscilloscope feature which is extremely useful to optimize settings and to verify proper detector behavior and is often the first feature used in Nyx during detector setup. Finally, Nyx allows the user to collect data in several formats including full pulse shapes to basic histograms. Overall, it is the corner stone for the transition of beta-gamma systems to a state-of-the-art digitizing DAQ.

    Imaging station for detecting cracks and flaws in solid materials developed combining both ultrasonic C-scan and eddy-current imaging. Incorporation of both techniques into one system eliminates duplication of computers and of mechanical scanners; unifies acquisition, processing, and storage of data; reduces setup time for repetitious ultrasonic and eddy-current scans; and increases efficiency of system. Same mechanical scanner used to maneuver either ultrasonic or eddy-current probe over specimen and acquire point-by-point data. For ultrasonic scanning, probe linked to ultrasonic pulser/receiver circuit card, while, for eddy-current imaging, probe linked to impedance-analyzer circuit card. Both ultrasonic and eddy-current imaging subsystems share same desktop-computer controller, containing dedicated plug-in circuit boards for each.

  10. Robotic data acquisition of directional reflectance factors

    A data collection platform for rapid and repeatable positioning of a down-looking radiometer was constructed using commercially available instrumentation and hardware. The platform also accommodated a second radiometer to measure irradiance at the same instant the other radiometer measured target radiance. Stepper motors position the down-looking radiometer at programmed view zenith and view azimuth angles. A Polycorder and stepper motor interface control the stepper motors while data acquisition is the sole responsibility of the Polycorder. Less than 15 min is required to measure target radiance from a full set of measurements consisting of 182 combinations of view zenith and view azimuth angles. Positioning accuracy of the viewing radiometer is within ± 0.2° for a nominal 15° angular movement. The system has proven to be dependable, easy to use, highly mobile, and adaptable. (author)

  11. Jefferson Lab Data Acquisition Run Control System

    A general overview of the Jefferson Lab data acquisition run control system is presented. This run control system is designed to operate the configuration, control, and monitoring of all Jefferson Lab experiments. It controls data-taking activities by coordinating the operation of DAQ sub-systems, online software components and third-party software such as external slow control systems. The main, unique feature which sets this system apart from conventional systems is its incorporation of intelligent agent concepts. Intelligent agents are autonomous programs which interact with each other through certain protocols on a peer-to-peer level. In this case, the protocols and standards used come from the domain-independent Foundation for Intelligent Physical Agents (FIPA), and the implementation used is the Java Agent Development Framework (JADE). A lightweight, XML/RDF-based language was developed to standardize the description of the run control system for configuration purposes

    2016-04-01

    The Discovering Australia's Mineral Resources Program of CSIRO is conducting a study to develop novel methods and techniques to reliably define distal footprints of mineral systems under regolith cover in the Capricorn Orogen - the area that lies between two well-known metallogenic provinces of Pilbara and Yilgarn Cratons in Western Australia. The multidisciplinary study goes beyond the boundaries of a specific discipline and aims at developing new methods to integrate heterogeneous datasets to gain insight into the key indicators of mineralisation. The study relies on large regional datasets obtained from previous hydrogeochemical, regolith, and resistate mineral studies around known deposits, as well as new data obtained from the recent field sampling campaigns around areas of interest. With thousands of water, vegetation, rock and soil samples collected over the past years, it has prompted us to look at ways to standardise field sampling procedures and review the data acquisition process. This process has evolved over the years (Golodoniuc et al., 2015; Klump et al., 2015) and has now reached the phase where fast and reliable collection of scientific data in remote areas is possible. The approach is backed by a unified discipline-agnostic platform - the Federated Archaeological Information Management System (FAIMS). FAIMS is an open source framework for mobile field data acquisition, developed at the University of New South Wales for archaeological field data collection. The FAIMS framework can easily be adapted to a diverse range of scenarios, different kinds of samples, each with its own peculiarities, integration with GPS, and the ability to associate photographs taken with the device embedded camera with captured data. Three different modules have been developed so far, dedicated to geochemical water, plant and rock sampling. All modules feature automatic date and position recording, and reproduce the established data recording workflows. The rock sampling

  14. A Data Acquisition System for Medical Imaging

    A data acquisition system for medical imaging applications is presented. Developed at CPPM, it provides high performance generic data acquisition and processing capabilities. The DAQ system is based on the PICMG xTCA standard and is composed of 1 up to 10 cards in a single rack, each one with 2 Altera Stratix IV FPGAs and a Fast Mezzanine Connector (FMC). Several mezzanines have been produced, each one with different functionalities. Some examples are: a mezzanine capable of receiving 36 optical fibres with up to 180 Gbps sustained data rates or a mezzanine with 12 x 5 Gbps input links, 12 x 5 Gbps output links and an SFP+ connector for control purposes. Several rack sizes are also available, thus making the system scalable from a one card desktop system useful for development purpose up to a full featured rack mounted DAQ for high end applications. Depending on the application, boards may exchange data at speeds of up to 25.6 Gbps bidirectional sustained rates in a double star topology through back-plane connections. Also, front panel optical fibres can be used when higher rates are required by the application. The system may be controlled by a standard Ethernet connection, thus providing easy integration with control computers and avoiding the need for drivers. Two control systems are foreseen. A Socket connection provides easy interaction with automation software regardless of the operating system used for the control PC. Moreover a web server may run on the Envision cards and provide an easy intuitive user interface. The system and its different components will be introduced. Some preliminary measurements with high speed signal links will be presented as well as the signal conditioning used to allow these rates. (authors)

  15. E787 data acquisition software architecture

    Brookhaven National Laboratory (BNL) Experiment 787's second generation Unix-based data acquisition system is comprised of several independent programs, each of which controls a specific aspect of the experiment. These programs include packages for reading events from the hardware systems, analyzing and reducing the data, distributing the results to various data consumers, and logging the data to tape or disk. Most of these can be run in stand-alone mode, for ease of development and testing. There are also a number of daemon processes for writing special data records to the data streams, and several monitor programs for evaluating and controlling and progress of the whole. Coordination of these processes is achieved through a combination of pipes, signals, shared memory, and FIFOs, overseen by the user through a Motif graphical user interface. The system runs on a Silicon Graphics 4D/320, interfaced to a Fastbus system through the BNL Fastbus/VME interface (BBFC), and runs under Irix and Motif/X-windows

  16. Supercritical Water Oxidation Data Acquisition Testing

    Supercritical Water Oxidation (SCWO) is a high pressure oxidation process that blends air, water, and organic waste material in an oxidizer in which where the temperature and pressure in the oxidizer are maintained above the critical point of water. Supercritical water mixed with hydrocarbons, which would be insoluble at subcritical conditions, forms a homogeneous phase which possesses properties associated with both a gas and a liquid. Hydrocarbons in contact with oxygen and SCW are readily oxidized. These properties of SCW make it an attractive means for the destruction of waste streams containing organic materials. SCWO technology holds great promise for treating mixed wastes in an environmentally safe and efficient manner. In the spring of 1994 the U.S. Department of Energy (DOE) initiated a Supercritical Water Oxidation Data Acquisition Testing (SCWODAT) program. The SCWODAT program provided further information and operational data on the effectiveness of treating both simulated mixed waste and typical Navy hazardous waste using the SCWO technology. The program concentrated on the acquisition of data through pilot plant testing. The Phase I DOE testing used a simulated waste stream that contained a complex machine cutting oil and metals, that acted as surrogates for radionuclides. The Phase II Navy testing included pilot testing using hazardous waste materials to demonstrate the effectiveness of the SCWO technology. The SCWODAT program demonstrated that the SCWO process oxidized the simulated waste stream containing complex machine cutting oil, selected by DOE as representative of one of the most difficult of the organic waste streams for which SCWO had been applied. The simulated waste stream with surrogate metals in solution was oxidized, with a high destruction efficiency, on the order of 99.97%, in both the neutralized and unneutralized modes of operation

  17. Soudan 2 data acquisition and trigger electronics

    The 1.1 kton Soudan 2 calorimetric drift-chamber detector is read out by 16K anode wires and 32K cathode strips. Preamps from each wire or strip are bussed together in groups of 8 to reduce the number of ADC channels. The resulting 6144 channels of ionization signal are flash-digitized every 200 ns and stored in RAM. The raw data hit patterns are continually compared with programmable trigger multiplicity and adjacency conditions. The data acquisition process is managed in a system of 24 parallel crates each containing an Intel 80C86 microprocessor, which supervises a pipe-lined data compactor, and allows transfer of the compacted data via CAMAC to the host computer. The 80C86's also manage the local trigger conditions and can perform some parallel processing of the data. Due to the scale of the system and multiplicity of identical channels, semi-custom gate array chips are used for much of the logic, utilizing 2.5 micron CMOS technology

  19. Data acquisition system for atmospheric Lidar

    For the purpose of improving the detection range of lidar which is used in atmospheric environmental monitoring, a solution that single photon counter and photomultiplier work together was proposed. The photomultiplier was applied to detect strong signal echoing from a short distance, while single photon counter was used to record remote and weak echo signal. The data acquired in this way were accumulated to increase SRN. According to the requirement of DIAL, A high-speed and high-precision dual-channel data acquisition system was designed and implemented for lidar. The system which was based on FPGA sampled signals with a 14 bits ADC and acquired data in real time through hardware logic as well as transported data to computer via USB2.0 bus. The result of experiments demonstrates that the detection range of atmospheric lidar is improved by this system. The result also shows that the system acquires data promptly, and provides high temporal and spatial resolution, which means that it can satisfy the requirements of atmospheric Liar. (authors)

  20. Data acquisition with fiber optic sensors

    Kist, R.

    The advantages of using fiber optic sensors for data acquisition are discussed, and their present utilization in this area is examined. Because of their high cost, these sensors are not likely to be competitive in general metrological applications in the near future. They do, however, provide important advantages in specific areas such as isolation against high voltage and immunity against electromagnetic fields and explosive and/or corrosive environments. They also offer the possibility of miniaturized and compact packaging of the sensing element an application within a broad temperature range. Multimode fiber optic sensors for parameters such as temperature, pressure, and refractive index have more immediate commercial potential than monomode fiber optic sensors, which have higher costs. The latter allow for high precision solutions of metrological tasks under specific conditions, and will be utilized in the foreseeable future.

  1. Data acquisition and analysis in radiation spectrometry

    Many radiation spectrometers (e.g. for gamma-rays, alpha-particles) produce signals that require pulse height analysis. Because the radiation detectors differ in resolution and range, the task of pulse height analysis needs to be flexible as well as reliable and efficient. A commercially available computer based system which fulfils these requirements is described. It consists of 112 K words of 16-bit solid state memory, dual hard-disk drive, dual flexible disk-drive, line-printer and a general interface. Acquisition of data is by eleven ADCs. The system is multi-user and multi-task based. The supplied package of application programs is described and over a 2 year period, the system has only been inoperative when the disk-drive failed.

  2. A Lossless Switch for Data Acquisition Networks

    Jereczek, Grzegorz Edmund; The ATLAS collaboration

    2015-01-01

    The recent trends in software-defined networking (SDN) and network function virtualization (NFV) are boosting the advance of software-based packet processing and forwarding on commodity servers. Although performance has traditionally been the challenge of this approach, this situation changes with modern server platforms. High performance load balancers, proxies, virtual switches and other network functions can be now implemented in software and not limited to specialized commercial hardware, thus reducing cost and increasing the flexibility. In this paper we design a lossless software-based switch for high bandwidth data acquisition (DAQ) networks, using the ATLAS experiment at CERN as a case study. We prove that it can effectively solve the incast pathology arising from the many-to-one communication pattern present in DAQ networks by providing extremely high buffering capabilities. We evaluate this on a commodity server equipped with twelve 10 Gbps Ethernet interfaces providing a total bandwidth of 120 Gbps...

    2015-01-01

    The Data Acquisition System of the LZ experiment, the 10-tonne dark matter detector to be installed at the Sanford Underground Research Facility (SURF), will collect signals from 788 photomultiplier tubes (PMTs). Because the signals from the time projection chamber PMTs will be passed through dual-gain amplifiers, the DAQ system will collect waveforms from a total of 1276 channels, using custom built, 32-channel, FPGA-based digital signal processors. The appropriately conditioned signals will be digitized at 100 MHz with 14-bit resolution. Based on actual measurements with a small-scale prototype system, the LZ DAQ is expected to be able to handle a maximum sparsified data rate of ~1500 MB/s. During calibrations, it is estimated that only 33% of the system resources are utilized. The digital filters that are used for data selection operate with an aggregate throughput in excess of 595,000 MB/s. Data selection decisions are based on, for example, the amount of scintillation (S1) and photoluminescence S2 light,...

  5. Data transmission and acquisition in NEMO

    A comprehensive system for data transmission and acquisition has been developed for an 'a la NEMO' underwater neutrino telescope based on Cerenkov light detection using photomultipliers (PMTs) as sensors. Signals generated by each sensor are triggered, sampled and tagged by an electronics board, called Front End Module (FEM). Data streams from up to eight FEMs located on one tower floor are collected by a concentration board called Floor Control Module (FCM) and sent to a twin FCM board-located at the onshore station and plugged into an interface machine (FCM Interface, or FCMI) via a PCI bus-through a DWDM-compliant optical fiber and using a self-synchronous serial protocol. All sensor data reach the onshore lab through FCMI where they are made available to subsequent elaboration processes, such as time-wise alignment and muon track event-triggering. To meet requirements of the latter, onshore data unpacking is carried out with respect to their topological origin. The system promised, and keeps on showing, very light charges on power consumption and infrastructure complexity, while having recently proved to behave at high performance levels in its optical part

  7. HERA data acquisition over the Internet

    The next consequent step in the DESY network strategy is done. The large HERA experiments are using IP and the common DESY computer network to push their detector data from the experimental caves to the dedicated datalogging machines residing in the central DESY computer center. The consequences are obvious. No vendor specific hardware for machine interfaces or network components are necessary any longer. The underlying network protocols and hardware can follow the state of the art standard without a change in the transfer logic or software. Professional network monitoring tools based on snmp can be used to figure out malfunctions and potential bottlenecks in the data flow. The general DESY operating can take over the responsibility for the 24 hours availability of the data links as part of the general network, without additional knowledge about the application. To smoothen the step from the former special purpose solution to the new general one, the DESY computer center agreed to provide the necessary software to connect the experiment specific data acquisition systems with the datalogging machines, residing in the central computing center. The last part of this writeup presents the H1 solution which went into production with the start of the 94 run period. (author)

  8. Data acquisition system issues for large experiments

    Siskind, E. J.

    2007-09-01

    This talk consists of personal observations on two classes of data acquisition ("DAQ") systems for Silicon trackers in large experiments with which the author has been concerned over the last three or more years. The first half is a classic "lessons learned" recital based on experience with the high-level debug and configuration of the DAQ system for the GLAST LAT detector. The second half is concerned with a discussion of the promises and pitfalls of using modern (and future) generations of "system-on-a-chip" ("SOC") or "platform" field-programmable gate arrays ("FPGAs") in future large DAQ systems. The DAQ system pipeline for the 864k channels of Si tracker in the GLAST LAT consists of five tiers of hardware buffers which ultimately feed into the main memory of the (two-active-node) level-3 trigger processor farm. The data formats and buffer volumes of these tiers are briefly described, as well as the flow control employed between successive tiers. Lessons learned regarding data formats, buffer volumes, and flow control/data discard policy are discussed. The continued development of platform FPGAs containing large amounts of configurable logic fabric, embedded PowerPC hard processor cores, digital signal processing components, large volumes of on-chip buffer memory, and multi-gigabit serial I/O capability permits DAQ system designers to vastly increase the amount of data preprocessing that can be performed in parallel within the DAQ pipeline for detector systems in large experiments. The capabilities of some currently available FPGA families are reviewed, along with the prospects for next-generation families of announced, but not yet available, platform FPGAs. Some experience with an actual implementation is presented, and reconciliation between advertised and achievable specifications is attempted. The prospects for applying these components to space-borne Si tracker detectors are briefly discussed.

    2013-03-01

    Full Text Available Present launch vehicle integration architecture for avionics uses wired link to transfer data between various sub-systems. Depending on system criticality and complexity, MIL1553 and RS485 are the common protocols that are adopted. These buses have their inherent complexity and failure issues due to harness defects or under adverse flight environments. To mitigate this problem, a prototype wireless, data acquisition system for telemetry applications has been developed and demonstrated. The wireless system simplifies the integration, while reducing weight and costs. Commercial applications of wireless systems are widespread. Few systems have recently been developed for complex and critical environments. Efforts have been underway to make such architectures operational in promising application scenarios. This paper discusses the system concept for adapting a wireless system to the existing bus topology. The protocol involved and the internal implementation of the different modules are described. The test results are presented; some of the issues faced are discussed and the; future course of action is identified.Defence Science Journal, 2013, 63(2, pp.186-191, DOI:http://dx.doi.org/10.14429/dsj.63.4262

    2009-03-01

    Full Text Available Supervisory Control and Data Acquisition (SCADA is a field of constant devel¬opment and research. This project investigates on creating an extremely low cost device which can be adapted to many different SCADA applications via some very basic program¬ming, and plugging in the relevant peripherals. Much of the price in some expensive SCADA applications is a result of using specialized communication infrastructure. The application of infrastructure, in the proposed scheme the cost will come down. Additionally the generic nature of the device will be assured. Wireless SCADA deals with the creation of an inexpensive, yet adaptable and easy to use SCADA device and infrastructure using the mobile telephone network, in particular, the General Packet Radio Service (GPRS. The hardware components making up the device are relatively unsophisticated, yet the custom written software makes it re-programmable over the air, and able to provide a given SCADA application with the ability to send and receive control and data signals at any non predetermined time. GPRS is a packet-based radio service that enables “al¬ways on” connections, eliminating repetitive and time-consuming dial-up connections. It will also provide real throughput in excess of 40 Kbps, about the same speed as an excellent landline analog modem connection.

  14. Data acquisition system of a simulator

    The Nuclear Power Plant Simulator (NPPS) at Nuclear Training Centre (NTC), Rajasthan Atomic Power Station is primarily a training device required to achieve training programme for nuclear power plant operators. It has got a control room which is a replica of RAPS-1 Control Room. A 32 bit super micro computer (Motorala 68020 based) has been used as main simulation computer to simulate the responses of plant as per the input changes initiated by the operator in the form of operation of various hand switches and potentiometers. For achieving real time environment, the scanning of inputs from control panels and updating of information on various displays of control panels is executed every 200 milli seconds so that operator feels normal response of displays due to his actions. For data transaction between main simulator computer and control panels, data acquisition system based on TDC-316 computer manufactured by Electronics Corporation of India Ltd was installed and commissioned. The system is described. Experience and problems encountered in operation and maintenance, improvements and modifications carried out are described. (author)

  15. A prototype switched Ethernet data acquisition system

    A prototype switched Ethernet data acquisition system has been built up and successfully operated in HL-1M tokamak experiments. The system is based on a switched high bandwidth Ethernet network with which the CAMAC crates are directly interfaced. It takes the advanced features of LAN switch and Ethernet CAMAC controller (ECC 1365 MK III, HYTEC product) to avoid the rewriting of CAMAC driver for an individual computer system and to ensure high data transmission rate between CAMAC system and host computers on the network. It is a new approach to DAS system architecture and provides a solution for a well-known bottleneck problem in traditional distributed DAS system for fusion research. An average throughput of the test system reaches over 100 Mbps. The system features also an easy and low cost migration from traditional distributed DAS system. In the paper, the hardware configuration, software structure, performance of the system and the method of migrating from current DAS system are discussed in detail. (orig.)

  16. The DISTO Data Acquisition System at SATURNE

    Maggiora, A

    1997-01-01

    The DISTO collaboration has built a large-acceptance magnetic spectrometer designed to provide broad kinematic coverage of multi-particle final states produced in $pp$ scattering. The spectrometer has been installed in the polarized proton beam of the Saturne accelerator in Saclay to study polarization observables in the $\\vec{p} p \\to p K^{+} \\vec{Y}$ ($Y = \\Lambda, and $\\rho$) in $pp$ collisions. The data acquisition system is based on a VME 68030 CPU running the OS/9 operating system, housed in a single VME crate together with the CAMAC interface, the triple port ECL memories, and four RISC R3000 CPU. The digitization of signals from the detectors is made by PCOS III and FERA front-end electronics. Data of several events belonging to a single Saturne extraction are stored in VME triple-port ECL memories using a hardwired fast sequencer. The buffer, optionally filtered by the RISC R3000 CPU, is recorded on a DLT cassette by DAQ CPU using the on-board SCSI interface during the acceleration cycle. Two UNIX wo...

  17. Hardware upgrade for A2 data acquisition

    The A2 Collaboration uses an energy tagged photon beam which is produced via bremsstrahlung off the MAMI electron beam. The detector system consists of Crystal Ball and TAPS and covers almost the whole solid angle. A frozen-spin polarized target allows to perform high precision measurements of polarization observables in meson photo-production. During the last summer, a major upgrade of the data acquisition system was performed, both on the hardware and the software side. The goal of this upgrade was increased reliability of the system and an improvement in the data rate to disk. By doubling the number of readout CPUs and employing special VME crates with a split backplane, the number of bus accesses per readout cycle and crate was cut by a factor of two, giving almost a factor of two gain in the readout rate. In the course of the upgrade, we also switched most of the detector control system to using the distributed control system EPICS. For the upgraded control system, some new tools were developed to make full use of the capabilities of this decentralised slow control and monitoring system. The poster presents some of the major contributions to this project.

  18. FPGA Flash Memory High Speed Data Acquisition

    Gonzalez, April

    2013-01-01

    The purpose of this research is to design and implement a VHDL ONFI Controller module for a Modular Instrumentation System. The goal of the Modular Instrumentation System will be to have a low power device that will store data and send the data at a low speed to a processor. The benefit of such a system will give an advantage over other purchased binary IP due to the capability of allowing NASA to re-use and modify the memory controller module. To accomplish the performance criteria of a low power system, an in house auxiliary board (Flash/ADC board), FPGA development kit, debug board, and modular instrumentation board will be jointly used for the data acquisition. The Flash/ADC board contains four, 1 MSPS, input channel signals and an Open NAND Flash memory module with an analog to digital converter. The ADC, data bits, and control line signals from the board are sent to an Microsemi/Actel FPGA development kit for VHDL programming of the flash memory WRITE, READ, READ STATUS, ERASE, and RESET operation waveforms using Libero software. The debug board will be used for verification of the analog input signal and be able to communicate via serial interface with the module instrumentation. The scope of the new controller module was to find and develop an ONFI controller with the debug board layout designed and completed for manufacture. Successful flash memory operation waveform test routines were completed, simulated, and tested to work on the FPGA board. Through connection of the Flash/ADC board with the FPGA, it was found that the device specifications were not being meet with Vdd reaching half of its voltage. Further testing showed that it was the manufactured Flash/ADC board that contained a misalignment with the ONFI memory module traces. The errors proved to be too great to fix in the time limit set for the project.

    Zhu, Y.; Balke, K.

    2009-12-01

    For controlling land subsidence caused by groundwater over-exploitation, loading of engineered structures, mining and other anthropogenic activities in this fast changing world, a large variety of different data of various scales of concerning areas are needed for scientific study and administrative operational purposes. The economical, social and environmental impacts of anthropogenic land subsidence have long been recognized by many scientific institutions and management authorities based on results of monitoring and analysis at an interdisciplinary level. The land subsidence information systems composed of the surface and subsurface monitoring nets (monitoring and development wells, GPS stations and other facilities) and local data processing centers as a system management tool in Shanghai City was started with the use of GPS technology to monitor land subsidence in 1998. After years of experiences with a set of initiatives by adopting adequate countermeasures, the particular attention given to new improved methodologies to monitor and model the process of land subsidence in a simple and timely way, this is going to be promoted in the whole Yangtze River Delta region in China, where land subsidence expands in the entire region of urban cluster. The Delta land subsidence monitoring network construction aims to establish an efficient and coordinated water resource management system. The land subsidence monitoring network records "living history" of land subsidence, produces detailed scheduled reports and environmental impact statements. For the different areas with local factors and site characteristics, parallel packages need to be designed for predicting changes, land sensitivity and uncertainty analysis, especially for the risk analysis in the rapid growth of megacities and urban areas. In such cases, the new models with new types of local data and the new ways of data acquisition provide the best information for the decision makers for their mitigating

  5. MIDAS (Master Information and Data Acquisition System)

    Ball, D.L.

    1986-01-01

    The Master Information and Data Acquisition System (MIDAS) is a computerized work control system that provides 24-hour, real-time access to plant equipment information and work package status. It is used in the 400 Area of the Department of Energy (DOE) Hanford Site in Richland, Washington. MIDAS was originally created to aid in the release and control of work at the Fast Flux Test Facility (FFTF), which is operated by the Westinghouse Hanford Company for the DOE. After MIDAS performed that function at FFTF successfully for over two years, its role was expanded to provide similar functions for other facilities supporting the LMR mission. Through its ability to provide online, accurate information on plant components, safety criteria, and work package status, MIDAS reinforces Operations functions and the control and authorization of maintenance activities in the FFTF plant and in other related facilities. Thus, MIDAS enhances the operational safety, as well as the planning and scheduling process for these facilities. MIDAS consists of three parts: The Plant Tracking System (PTS), the Work Control Log (WCL), and the MIDAS Component Indices (MCI).

  8. CODA: A scalable, distributed data acquisition system

    A new data acquisition system has been designed for physics experiments scheduled to run at CEBAF starting in the summer of 1994. This system runs on Unix workstations connected via ethernet, FDDI, or other network hardware to multiple intelligent front end crates -- VME, CAMAC or FASTBUS. CAMAC crates may either contain intelligent processors, or may be interfaced to VME. The system is modular and scalable, from a single front end crate and one workstation linked by ethernet, to as may as 32 clusters of front end crates ultimately connected via a high speed network to a set of analysis workstations. The system includes an extensible, device independent slow controls package with drivers for CAMAC, VME, and high voltage crates, as well as a link to CEBAF accelerator controls. All distributed processes are managed by standard remote procedure calls propagating change-of-state requests, or reading and writing program variables. Custom components may be easily integrated. The system is portable to any front end processor running the VxWorks real-time kernel, and to most workstations supplying a few standard facilities such as rsh and X-windows, and Motif and socket libraries. Sample implementations exist for 2 Unix workstation families connected via ethernet or FDDI to VME (with interfaces to FASTBUS or CAMAC), and via ethernet to FASTBUS or CAMAC

    2000-01-01

    The LHCb experiment is the most recently approved of the 4 experiments under construction at CERNs LHC accelerator. It is a special purpose experiment designed to precisely measure the CP violation parameters in the B-B system. Triggering poses special problems since the interesting events containing B-mesons are immersed in a large background of inelastic p-p reactions. We therefore decided to implement a 4 level triggering scheme. The LHCb Data Acquisition (DAQ) system will have to cope with an average trigger rate of ~40 kHz, after two levels of hardware triggers, and an average event size of ~100 kB. Thus an event-building network which can sustain an average bandwidth of 4 GB/s is required. A powerful software trigger farm will have to be installed to reduce the rate from the 40 kHz to ~100 Hz of events written to permanent storage. In this paper we outline the general architecture of the Trigger and DAQ system and the readout protocols we plan to implement. First results of simulations of the behavior o...

  10. Control, data acquisition, data analysis and remote participation in LHD

    This paper presents the control, data acquisition, data analysis and remote participation facilities of the Large Helical Device (LHD), which is designed to confine the plasma in steady state. In LHD the plasma duration exceeds 3000 s by controlling the plasma position, the density and the ICRF heating. The 'LABCOM' data acquisition system takes both the short-pulse and the steady-state data. A two-layer Mass Storage System with RAIDs and Blu-ray Disk jukeboxes in a storage area network has been developed to increase capacity of storage. The steady-state data can be monitored with a Web browser in real time. A high-level data analysis system with Web interfaces is being developed in order to provide easier usage of LHD data and large FORTRAN codes in a supercomputer. A virtual laboratory system for the Japanese fusion community has been developed with Multi-protocol Label Switching Virtual Private Network Technology. Collaborators at remote sites can join the LHD experiment or use the NIFS supercomputer system as if they were working in the LHD control room

  11. Real-Time Wireless Data Acquisition System

    2007-01-01

    Current and future aerospace requirements demand the creation of a new breed of sensing devices, with emphasis on reduced weight, power consumption, and physical size. This new generation of sensors must possess a high degree of intelligence to provide critical data efficiently and in real-time. Intelligence will include self-calibration, self-health assessment, and pre-processing of raw data at the sensor level. Most of these features are already incorporated in the Wireless Sensors Network (SensorNet(TradeMark)), developed by the Instrumentation Group at Kennedy Space Center (KSC). A system based on the SensorNet(TradeMark) architecture consists of data collection point(s) called Central Stations (CS) and intelligent sensors called Remote Stations (RS) where one or more CSs can be accommodated depending on the specific application. The CS's major function is to establish communications with the Remote Stations and to poll each RS for data and health information. The CS also collects, stores and distributes these data to the appropriate systems requiring the information. The system has the ability to perform point-to-point, multi-point and relay mode communications with an autonomous self-diagnosis of each communications link. Upon detection of a communication failure, the system automatically reconfigures to establish new communication paths. These communication paths are automatically and autonomously selected as the best paths by the system based on the existing operating environment. The data acquisition system currently under development at KSC consists of the SensorNet(TradeMark) wireless sensors as the remote stations and the central station called the Radio Frequency Health Node (RFHN). The RFF1N is the central station which remotely communicates with the SensorNet(TradeMark) sensors to control them and to receive data. The system's salient feature is the ability to provide deterministic sensor data with accurate time stamps for both time critical and non

    Xenbase, the Xenopus model organism database (www.xenbase.org), is a cloud-based, web-accessible resource that integrates the diverse genomic and biological data from Xenopus research. Xenopus frogs are one of the major vertebrate animal models used for biomedical research, and Xenbase is the central repository for the enormous amount of data generated using this model tetrapod. The goal of Xenbase is to accelerate discovery by enabling investigators to make novel connections between molecular pathways in Xenopus and human disease. Our relational database and user-friendly interface make these data easy to query and allows investigators to quickly interrogate and link different data types in ways that would otherwise be difficult, time consuming, or impossible. Xenbase also enhances the value of these data through high-quality gene expression curation and data integration, by providing bioinformatics tools optimized for Xenopus experiments, and by linking Xenopus data to other model organisms and to human data. Xenbase draws in data via pipelines that download data, parse the content, and save them into appropriate files and database tables. Furthermore, Xenbase makes these data accessible to the broader biomedical community by continually providing annotated data updates to organizations such as NCBI, UniProtKB, and Ensembl. Here, we describe our bioinformatics, genome-browsing tools, data acquisition and sharing, our community submitted and literature curation pipelines, text-mining support, gene page features, and the curation of gene nomenclature and gene models.

    1981-01-01

    The nuclear physics program at the Brookhaven National Laboratory High Flux Beam Reactor (HFBR) employs a pair of PDP-11 computers for the dual functions of data acquisition and analysis. The data acquisition is accomplished through CAMAC and features a microprogrammed branch driver to accommodate various experimental inputs. The acquisition computer performs the functions of multi-channel analyzers, multiscaling and time-sequenced multichannel analyzers and gamma-ray coincidence analyzers. The data analysis computer is available for rapid processing of data tapes written by the acquisition computer. The ability to accommodate many users is facilitated by separating the data acquisition and analysis functions, and allowing each user to tailor the analysis to the specific requirements of his own experiment. The system is to be upgraded soon by the introduction of a dual port disk to allow a data base to be available to each computer.

  19. Fourth Data Challenge for the ALICE data acquisition system

    Maximilien Brice

    2003-01-01

    The ALICE experiment will study quark-gluon plasma using beams of heavy ions, such as those of lead. The particles in the beams will collide thousands of times per second in the detector and each collision will generate an event containing thousands of charged particles. Every second, the characteristics of tens of thousands of particles will have to be recorded. Thus, to be effective, the data acquisition system (DAQ) must meet extremely strict performance criteria. To this end, the ALICE Data Challenges entail step-by-step testing of the DAQ with existing equipment that is sufficiently close to the final equipment to provide a reliable indication of performance. During the fourth challenge, in 2002, a data acquisition rate of 1800 megabytes per second was achieved by using some thirty parallel-linked PCs running the specially developed DATE software. During the final week of tests in December 2002, the team also tested the Storage Tek linear magnetic tape drives. Their bandwidth is 30 megabytes per second a...

    Kneuer, E.; Schwartze, S. [Werum Datenverarbeitungssysteme GmbH, Lueneburg (Germany)

    2001-07-01

    This lecture introduces a concept of measurement technology with video integration for commercial vehicles. We would like to present DAVIS-CAR, a system for mobile data acquisition. It enables the simultaneous evaluation of video data and test data and consists of mobile as well as of stationary components in a client/server architecture. The product DAVIS-CAR is suitable not only for testing entire vehicles but for external suppliers developing vehicle components or for analysing a person's driving performance. Even for completely stationary systems DAVIS-CAR provides advantages in situations when video data are recorded to get additional information on tests. The mobile server collects the data of the driving car. The storage of these data can be triggered either manually or by events derived from signal states. The stationary system is capable of administering the measurement data and the associated Meta information from several mobile systems at the same time and of providing this information to the connected clients. The ASAM-ODS interface facilitates the integration of DAVIS-CAR in environments typically found in the automobile industry. The overall architecture also enables the integration of data provided by other measurement systems. (orig.)

    Giuse, D A; Giuse, N B; Bankowitz, R A; Miller, R A

    1991-06-01

    Knowledge acquisition for medical knowledge bases can be aided by programs that suggest possible values for portions of the data. The paper presents an experiment which was used in designing a heuristic to help the process of knowledge acquisition. The heuristic helps to determine numerical data from stylized literature excerpts in the context of knowledge acquisition for the QMR medical knowledge base. Quantitative suggestions from the heuristics are shown to agree substantially with the data incorporated in the final version of the knowledge base. The experiment shows the potential of knowledge base specific heuristics in simplifying the task of knowledge base creation. PMID:1868695

    Bodurka, Jerzy; Ledden, Patrick J; van Gelderen, Peter; Chu, Renxin; de Zwart, Jacco A; Morris, Doug; Duyn, Jeff H

    2004-01-01

    A scalable multichannel digital MRI receiver system was designed to achieve high bandwidth echo-planar imaging (EPI) acquisitions for applications such as BOLD-fMRI. The modular system design allows for easy extension to an arbitrary number of channels. A 16-channel receiver was developed and integrated with a General Electric (GE) Signa 3T VH/3 clinical scanner. Receiver performance was evaluated on phantoms and human volunteers using a custom-built 16-element receive-only brain surface coil array. At an output bandwidth of 1 MHz, a 100% acquisition duty cycle was achieved. Overall system noise figure and dynamic range were better than 0.85 dB and 84 dB, respectively. During repetitive EPI scanning on phantoms, the relative temporal standard deviation of the image intensity time-course was below 0.2%. As compared to the product birdcage head coil, 16-channel reception with the custom array yielded a nearly 6-fold SNR gain in the cerebral cortex and a 1.8-fold SNR gain in the center of the brain. The excellent system stability combined with the increased sensitivity and SENSE capabilities of 16-channel coils are expected to significantly benefit and enhance fMRI applications. PMID:14705057

  2. A novel time stamping technique for distributed data acquisition systems.

    Subramaniam, E T

    2012-12-01

    In this paper, we discuss the design and implementation of a synchronizing technique for data acquisition systems, which can effectively use the normal, standard local area network cables to provide a time stamp, with a range up to 32 days, resolution of 10 ns, and synchronization within ± 5 ns. This system may be used to synchronize data being collected by independent heterogeneous data acquisition modules, that acquire events independently. Such distributed systems are generally designed with a tree-like structure or independent self-triggered acquisition boxes. These leaf edges are connected through branches to the root node, via non-bus based inter-connecting links. The present system has been tested with a set of self-triggered digital signal processing based data acquisition engines, having a 100 MHz analog to digital converter front end. PMID:23277988

  3. Increasing Density and Reducing Costs of Data Acquisition

    Schmalzel, J. L.; Krchnavek, R. R.; Figueroa, J. Fernando; Solano, Wanda

    2001-01-01

    There are a number of reasons why it is important to increase the density of data acquisition functions. Sensor fusion seeks to integrate large numbers of sensors into a decision network. Addition of health monitoring functions may incur additional sensor requirements. But at the same time, it is important to reduce the per-channel costs of data acquisition systems. Often the most significant cost is the management of data acquisition networks, which incurs substantial costs associated with transducer installation, configuration, calibration, and maintenance. Alternatives that lower the cost of the transducer system and reduce the data acquisition system channel count will directly impact initial system costs. Other techniques that affect maintenance and operating costs will contribute to reducing life cycle costs. This paper describes work undertaken to explore alternative architectures for lowering the cost per transducer function using a MEMS-based accelerometer as the model.

  4. Parallel Port Interface ADC for Real Time Data Acquisition

    A parallel port interface ADC for real time data acquisition has been designed and developed indigenously. The ADC has been designed by utilizing the data input capabilities of the computer parallel port. In addition to a basic ADC chip, it has been required to incorporate some additional hardware and software components such as parallel port data bus interface, control bits decoder, driver software and acquisition software to realize this ADC. The data acquisition software has been developed under the Visual Basic (VB) programming language environment. The driver software, to enable the VB of port access capability, has been obtained from the website. The main hardware component of the developed ADC is AD574 IC. The AD574 chip is a complete 12 bit successive approximation analogue to digital converter with 3-state output buffer circuitry for direct interface to a data bus. 8-bit data bus buffer is used to interface the ADC output to the parallel port data lines. The control pulses, as required by AD574, are generated by decoding the control bits C0-C3 of the control register. C5 bit of the control register is set to the proper logic value to determine the direction of data would be appeared on the data bus (D0 - D7) of the parallel port. Standard features, such as on-line acquisition, data display, data save, data retrieve, etc. options, are included in the acquisition software. (author)

    Khan, Fitratullah; Cavalcanti, Marcelo

    1994-05-01

    A data acquisition/controller system was required for gathering data simultaneously from different radars located spatially apart. Problems encountered in the earlier generation of data acquisition systems were to be alleviated. One of the major problems was the corruption of weak signals by noise on long analog signal cables. Some evidence of video display being another source of noise was also found. Another goal was to reduce the amount of cable going from radar sites to the operator's computer.

  10. Data acquisition system in TPE-1RM15

    The data acquisition system for TPE-1RM15 reversed field pinch machine had been developed and has recently been completed. Thd data to be acquired consist of many channels of time series data which come from plasma diagnostics. The newly developed data acquisition system uses CAMAC (Computer Automated Measurement And Control) system as a front end data acquisition system and micro-VAX II for control, file management and analyses. Special computer programs, DAQR/D, have been developed for data acquisition routine. Experimental setting and process controlling items are managed by a parameter database in a shared common region and every task can easily refer to it. The acquired data are stored into a mass storage system (total of 1.3GBytes plus a magnetic tape system) including an optical disk system, which can save storage space and allow quick reference. At present, the CAMAC system has 88 (1MHz sampling) and 64(5kHz sampling) channels corresponding to 1.6 MBytes per shot. The data acquisition system can finish one routine within 5 minutes with 1.6MBytes data depending on the amount of graphic outputs. Hardwares and softwares of the system are specified so that the system can be easily expanded. The computer is connected to the AIST Ethernet and the system can be remotely accessed and the acquired data can be transferred to the mainframes on the network. Details about specifications and performance of the system are given in this report. (author)

    Yang Xuanhui; Yang Shuxin; Zhang Bin; Zhang Guohong; Liu Fusheng; Liu Yanzhi; Wang Yong

    2012-01-01

    A seismometer data acquisition unit has been used in the Changping seismic station to record the output of a strainmeter. The output of a strainmeter was sampled at a rate of l00/sec by seismometer acquisition from the original rate of 1 per minute. Plenty of high frequency sampled data was recorded. The minute value curve calculated from the seismometer acquisition are consistent with that of the original data sampled by the strain acquisition system. More complete waveforms were recorded with a higher sampling rate, and seismic phase parameters calculated by using higher sampling rate strain seismic waves are also in consistency with the results of its predecessors. Spectra of the strain seismic waves are compared with that of seismic waves recorded by a seismometer in the Shisanling seismic station, and their trends are almost the same. Besides, some lower frequency components still exist in strain seismic waves.

    2014-12-01

    As part of a collaborative effort with the Incorporated Research Institutions for Seismology, a virtualized seismic data acquisition and processing system was recently installed at the Centro Sismológical Nacional (CSN) at the Universidad de Chile for use as part of their early warning system. Using lessons learned from the Earthscope Transportable Array project, the design of this system consists of dedicated acquisition, processing and data distribution nodes hosted on a high availability hypervisor cluster. Data is exchanged with the IRIS Data Management Center and the existing processing infrastructure at the CSN. The processing nodes are backed by 20 TB of hybrid Solid State Disk (SSD) and spinning disk storage with automatic tiering of data between the disks. As part of the installation, best practices for station metadata maintenance were discussed and applied to the existing IRIS sponsored stations, as well as over 30 new stations being added to the early warning network. Four virtual machines (VM) were configured with distinctive tasks. Two VMs are dedicated to data acquisition, one to the real-time data processing, and one as relay between data acquisition and processing systems with services for the existing earthquake revision and dissemination infrastructure. The first acquisition system connects directly to Basalt dataloggers and Q330 digitizers, managing them, and acquiring seismic data as well as state-of-health (SOH) information. As newly deployed stations become available (beyond the existing 30), this VM is configured to acquire data from them and incorporate the additonal data. The second acquisition system imports the legacy network of CSN and data streams provided by other data centers. The processing system is connected to the production and archive databases. The relay system merges all incoming data streams and obtains the processing results. Data and processing packets are available for subsequent review and dissemination by the CSN. Such

  14. Multimodal acquisition of articulatory data: Geometrical and temporal registration.

    Aron, Michaël; Berger, Marie-Odile; Kerrien, Erwan; Wrobel-Dautcourt, Brigitte; Potard, Blaise; Laprie, Yves

    2016-02-01

    Acquisition of dynamic articulatory data is of major importance for studying speech production. It turns out that one technique alone often is not enough to get a correct coverage of the whole vocal tract at a sufficient sampling rate. Ultrasound (US) imaging has been proposed as a good acquisition technique for the tongue surface because it offers a good temporal sampling, does not alter speech production, is cheap, and is widely available. However, it cannot be used alone and this paper describes a multimodal acquisition system which uses electromagnetography sensors to locate the US probe. The paper particularly focuses on the calibration of the US modality which is the key point of the system. This approach enables US data to be merged with other data. The use of the system is illustrated via an experiment consisting of measuring the minimal tongue to palate distance in order to evaluate and design Magnetic Resonance Imaging protocols well suited for the acquisition of three-dimensional images of the vocal tract. Compared to manual registration of acquisition modalities which is often used in acquisition of articulatory data, the approach presented relies on automatic techniques well founded from geometrical and mathematical points of view.

  15. An intelligent data acquisition system for fluid mechanics research

    Cantwell, E. R.; Zilliac, G.; Fukunishi, Y.

    1989-01-01

    This paper describes a novel data acquisition system for use with wind-tunnel probe-based measurements, which incorporates a degree of specific fluid dynamics knowledge into a simple expert system-like control program. The concept was developed with a rudimentary expert system coupled to a probe positioning mechanism operating in a small-scale research wind tunnel. The software consisted of two basic elements, a general-purpose data acquisition system and the rulebased control element to take and analyze data and supplying decisions as to where to measure, how many data points to take, and when to stop. The system was validated in an experiment involving a vortical flow field, showing that it was possible to increase the resolution of the experiment or, alternatively, reduce the total number of data points required, to achieve parity with the results of most conventional data acquisition approaches.

    We present a general-purpose, VMEbus based, multiprocessor data acquisition and monitoring system. Events, handled by a master CPU, are kept at the disposal of data storage and monitoring processes which can run on distinct processors. They access either the complete set of data or a fraction of them, minimizing the acquisition dead-time. The system is built with the VxWorks 5.0 real time kernel to which we have added device drivers for data acquisition and monitoring. The acquisition is controlled and the data are displayed on a workstation. The user interface is written in C++ and re-uses the classes of the Interviews and the NIH libraries. The communication between the control workstation and the VMEbus processors is made through SUN RPCs on an Ethernet link. The system will be used for, CAMAC based, data acquisition for nuclear physics experiments as well as for the VXI data taking with the 4π configuration (100 neutron detectors) of the Brussels-Caen-Louvian-Strasbourg DEMON collaboration.

  3. Implementation of High Speed Distributed Data Acquisition System

    Raju, Anju P.; Sekhar, Ambika

    2012-09-01

    This paper introduces a high speed distributed data acquisition system based on a field programmable gate array (FPGA). The aim is to develop a "distributed" data acquisition interface. The development of instruments such as personal computers and engineering workstations based on "standard" platforms is the motivation behind this effort. Using standard platforms as the controlling unit allows independence in hardware from a particular vendor and hardware platform. The distributed approach also has advantages from a functional point of view: acquisition resources become available to multiple instruments; the acquisition front-end can be physically remote from the rest of the instrument. High speed data acquisition system transmits data faster to a remote computer system through Ethernet interface. The data is acquired through 16 analog input channels. The input data commands are multiplexed and digitized and then the data is stored in 1K buffer for each input channel. The main control unit in this design is the 16 bit processor implemented in the FPGA. This 16 bit processor is used to set up and initialize the data source and the Ethernet controller, as well as control the flow of data from the memory element to the NIC. Using this processor we can initialize and control the different configuration registers in the Ethernet controller in a easy manner. Then these data packets are sending to the remote PC through the Ethernet interface. The main advantages of the using FPGA as standard platform are its flexibility, low power consumption, short design duration, fast time to market, programmability and high density. The main advantages of using Ethernet controller AX88796 over others are its non PCI interface, the presence of embedded SRAM where transmit and reception buffers are located and high-performance SRAM-like interface. The paper introduces the implementation of the distributed data acquisition using FPGA by VHDL. The main advantages of this system are high

    A fully implantable neural data acquisition system is a key component of a clinically viable brain-machine interface. This type of system must communicate with the outside world and obtain power without the use of wires that cross through the skin. We present a 96-channel fully implantable neural data acquisition system. This system performs spike detection and extraction within the body and wirelessly transmits data to an external unit. Power is supplied wirelessly through the use of inductively coupled coils. The system was implanted acutely in sheep and successfully recorded, processed and transmitted neural data. Bidirectional communication between the implanted system and an external unit was successful over a range of 2 m. The system is also shown to integrate well into a brain-machine interface. This demonstration of a high channel-count fully implanted neural data acquisition system is a critical step in the development of a clinically viable brain-machine interface. PMID:19255459

    The CMS silicon strip tracker, providing a sensitive area of approximately 200 m2 and comprising 10 million readout channels, has recently been completed at the tracker integration facility at CERN. The strip tracker community is currently working to develop and integrate the online and offline software frameworks, known as XDAQ and CMSSW respectively, for the purposes of data acquisition and detector commissioning and monitoring. Recent developments have seen the integration of many new services and tools within the online data acquisition system, such as event building, online distributed analysis, an online monitoring framework, and data storage management. We review the various software components that comprise the strip tracker data acquisition system, the software architectures used for stand-alone and global data-taking modes. Our experiences in commissioning and operating one of the largest ever silicon micro-strip tracking systems are also reviewed.

  7. SAR: A fast computer for Camac data acquisition

    This paper describes a special data acquisition and processing facility developed for Nuclear Physics experiments at intermediate energy installed at SATURNE (France) and at CERN (Geneva, Switzerland). Previously, we used a PDP 11/45 computer which was connected to the experiments through a Camac Branch highway. In a typical experiment (340 words per event), the computer limited the data acquisition rate at 4 μsec for each 16-bit transfer and the on-line data reduction at 20 events per second only. The initial goal of this project was to increase these two performances. Previous known acquisition processors were limited by the memory capacity these systems could support. Most of the time the data reduction was done on the host mini computer. Higher memory size can be designed with new fast RAM (Intel 2147) and the data processing can now take place on the front end processor

  11. An Overview of the LIGO Control and Data Acquisition System

    Bork, R G; Barker, D; Heefner, J W

    2001-01-01

    The LIGO Control and Data system (CDS) features a tightly coupled and highly integrated control and data acquisition system. Control of the interferometers requires many Multiple Input Multiple Output (MIMO) control loops closed both locally and across the 4-kilometer interferometer arm lengths. In addition to providing the closed loop control, the control systems front end processors act as Data Collection Units (DCU) for the data acquisition system. Data collected by these front ends and the data acquisition system must be collected and time stamped to an accuracy of 1 microsecond and made available to on-line analysis tools such as the Global Diagnostics System (GDS)[1]. Data is also sent to the LIGO Data Analysis System (LDAS)[2] for long-term storage and off-line analysis. Data rates exceed 5 Mbytes per second per interferometer continuous. Connection between the various front end processors and the data acquisition system is achieved using fiber optic reflective memory networks. Both controls and data a...

  12. Auxiliary DCP data acquisition system. [airborne system

    Snyder, R. V.

    1975-01-01

    An airborne DCP Data Aquisition System has been designed to augment the ERTS satellite data recovery system. The DCP's are data collection platforms located at pertinent sites. With the appropriate sensors they are able to collect, digitally encode and transmit environmental parameters to the ERTS satellite. The satellite in turn relays these transmissions to a ground station for processing. The satellite is available for such relay duty a minimum of two times in a 24-hour period. The equipment is to obtain continuous DCP data during periods of unusual environmental activity--storms, floods, etc. Two circumstances contributed to the decision to design such a system; (1) Wallops Station utilizes surveillance aircraft in support of rocket launches and also in support of earth resources activities; (2) the area in which Wallops is located, the Delaware and Chesapeake Bay areas, are fertile areas for DCP usage. Therefore, by developing an airborne DCP receiving station and installing it on aircraft more continuous DCP data can be provided from sites in the surrounding areas at relatively low cost.

  15. Real-time UNIX in HEP data acquisition

    Today's experimentation in high energy physics is characterized by an increasing need for sensitivity to rare phenomena and complex physics signatures, which require the use of huge and sophisticated detectors and consequently a high performance readout and data acquisition. Multi-level triggering, hierarchical data collection and an always increasing amount of processing power, distributed throughout the data acquisition layers, will impose a number of features on the software environment, especially the need for a high level of standardization. Real-time UNIX seems, today, the best solution for the platform independence, operating system interface standards and real-time features necessary for data acquisition in HEP experiments. We present the results of the evaluation, in a realistic application environment, of a Real-Time UNIX operating system: the EP/LX real-time UNIX system. ((orig.))

  16. ISOTDAQ - where students learn about trigger and data acquisition

    CERN Bulletin

    2011-01-01

    Where can students learn to implement a good trigger and to design the data acquisition system for today’s increasingly complex experiments? Universities rarely include classes on such specific topics. The ISOTDAQ School trains students and helps them gain hands-on experience of trigger systems, data-acquisition hardware and software, and data-transfer technologies.   One of the commercially available FPGA development boards from Altera. This was used in one of the practical exercises at ISOTDAQ2011 to teach students the principles of FPGA programming.

    2009-01-01

    New developments in the proton-therapy field for cancer treatments, leaded Italian physics researchers to realize a proton imaging apparatus consisting of a silicon microstrip tracker to reconstruct the proton trajectories and a calorimeter to measure their residual energy. For clinical requirements, the detectors used and the data acquisition system should be able to sustain about 1 MHz proton rate. The tracker read-out, using an ASICs developed by the collaboration, acquires the signals detector and sends data in parallel to an FPGA. The YAG:Ce calorimeter generates also the global trigger. The data acquisition system and the results obtained in the calibration phase are presented and discussed.

  19. CORBA technology in reengineering the FTU data acquisition system

    In its early stages, Frascati tokamak upgrade DAS was essentially devoted to acquiring data from experiments in CAMAC standard, using a software system (code and database) entirely written by domestic professionals. In 15 years of life DAS has been growing in size and complexity, still preserving its original structure; at the same time new standards were introduced (VME, PCI) to take into account users' ever increasing demands for amount of data and acquisition frequency with which the existing code couldn't cope. Moreover, machines were getting old and the maintenance became troublesome. Finally, the data archive porting to Unix has definitely shown that the DAS system was ageing and a thorough redesign was needed. The system we are planning to introduce is founded on a standard CORBA bus: (i) to integrate heterogeneous platforms and define a standard layer for interactions between the different acquisition units; (ii) to grant, with open source tools (MySql) and interfaces (Html and Java), unified access to hardware and software configuration data. So, a dedicated PC server, connected via a suitable PCI serial highway driver card, will perform the CAMAC access for all the clients interacting through the CORBA layer. Up to now we have successfully tested CAMAC access, and we designed an acquisition unit, which will be the building block of the new system. The next step will be migrating to Alpha/VMS the software related to CAMAC data acquisition, which has been so far the cornerstone of the whole DAS; it will be completely redesigned to fit the 'acquisition unit' paradigm we have defined. Finally we will have a fully distributed data acquisition system with VME (at present six such units have been operating since 1999) and PCI stations, an Alpha/VMS client of the CAMAC/PC server and any possible platform interacting through a CORBA bus for getting data configuration, synchronisation and data archiving

  20. Data Management and Acquisition System for INAA

    Instrumental neutron activation analysis (INAA) remains a powerful technique for multielemental trace analysis. In atmospheric aerosol studies, we typically determine 40 elements, including markers of natural and anthropogenic sources, heavy metals, and toxic or nutrient trace elements in aerosol samples. The need for size spectral, spatial, and temporal information requires that hundreds of samples be collected and accurately analyzed. Quality assurance is a primary component of the analytical protocol. The quality of INAA data depends on counting statistics--accurate preparation of standards, positioning of samples above the detector, resolution of interferences, and correction for coincidence effects when counting close to the detector--and on reliable operation of the amplifier and analog-to-digital converters. Furthermore, the analysis of such large numbers of samples by INAA is a complicated endeavor, involving a large number of tasks that, if not recorded or completed properly, can compromise the analysis. To reduce the possibility of operator error in keeping track of a complex array of information and to speed the detection of instrumental faults, we have developed a new analysis protocol and automated sample analysis and management (SAM) software system. The SAM system is a relational database application designed to log data associated with the collection of atmospheric aerosol and associated samples collected with a variety of instruments, assist in choosing samples for analysis by a variety of techniques, schedule irradiation and counting for INAA, interface with the ORTEC Gamma Vision (GV) software, capture the analytical data, calculate elemental masses from activities provided by GV, and prepare first-tier data summaries and manipulations. All the sample and flux monitor counts are initiated through SAM

This information is transmitted through the telephone lines to a remote computer where it is displayed.

  2. A tomograph VMEbus parallel processing data acquisition system

    This paper describes a VME based data acquisition system suitable for the development of Positron Volume Imaging tomographs which use 3-D data for improved image resolution over slice-oriented tomographs. The data acquisition must be flexible enough to accommodate several 3-D reconstruction algorithms; hence, a software-based system is most suitable. Furthermore, because of the increased dimensions and resolution of volume imaging tomographs, the raw data event rate is greater than that of slice-oriented machines. These dual requirements are met by our data acquisition systems. Flexibility is achieved through an array of processors connected over a VMEbus, operating asynchronously and in parallel. High raw data throughput is achieved using a dedicated high speed data transfer device available for the VMEbus. The device can attain a raw data rate of 2.5 million coincidence events per second for raw events per second for raw events which are 64 bits wide. Real-time data acquisition and pre-processing requirements can be met by about forty 20 MHz Motorola 68020/68881 processors

  3. Upgrade of the HADES data acquisition system

    Next years HADES will be moved to the upcoming FAIR accelerator complex. Here, HADES-at-FAIR will continue its experimental program. Due to mentioned future plans, the detector undergoes an upgrade. In order to be able to take the data in the Au+Au collision system at 8 GeV/u with a sustained trigger rate of 20 kHz (in peak 100 kHz) and expected average amount of the data 300 MB/s, our trigger and readout system has to be improved. A major part of the new DAQ system is the general-purpose Trigger and Readout Board (TRB), which serves as a platform for all other subsystems. To broaden the spectrum of possible applications, in the future DAQ-systems, we added a very high data-rate digital interface connector to this board (15 Gbit/s). It gives the possibility to mount an add-on boards to the TRB. The add-on boards then provide the detector-specific interfaces (special connectors) or FEE (like ADCs) and additional computing resources (FPGAs). All required add-on modules for the HADES-at-FAIR upgrade have been built and their basic functionality has been tested. The major steps of the upgrade program are shown in several parts: overview of the general DAQ concept, general readout platform, readout electronics for our detectors (add-ons), new event building concept, slow control, trigger distribution system and moreover also a part of the front-end electronics.

  4. Reliability and maintainability data acquisition in equipment development tests

    The need for collection of reliability, maintainability, and availability data adds a new dimension to the data acquisition requirements of equipment development tests. This report describes the reliability and maintainability data that are considered necessary to ensure that sufficient and high quality data exist for a comprehensive, quantitative evaluation of equipment and system availability. These necessary data are presented as a set of data collection forms. Three data acquisition forms are discussed: an inventory and technical data form, which is filed by the design engineer when the design is finished or the equipment is received; an event report form, which is completed by the senior test operator at each shutdown; and a maintainability report, which is a collaborative effort between senior operators and lead engineers and is completed on restart. In addition, elements of a reliability, maintainability evaluation program are described. Emphasis is placed on the role of data, its storage, and use in such a program

  18. ATLAS Trigger and Data Acquisition Upgrades for High Luminosity LHC

    Allen, Benjamin William; The ATLAS collaboration

    2016-01-01

    The ATLAS experiment at CERN is planning a second phase of upgrades to prepare for the "High Luminosity LHC", a 4th major run due to start in 2026. In order to deliver an order of magnitude more data than previous runs, 14 TeV protons will collide with an instantaneous luminosity of 7.5 × 1034 cm−2s−1, resulting in much higher pileup and data rates than the current experiment was designed to handle. While this extreme scenario is essential to realise the physics programme, it is a huge challenge for the detector, trigger, data acquisition and computing. The detector upgrades themselves also present new requirements and opportunities for the trigger and data acquisition system. Initial upgrade designs for the trigger and data acquisition system are shown, including the real time low latency hardware trigger, hardware-based tracking, the high throughput data acquisition system and the commodity hardware and software-based data handling and event filtering.

  4. Data acquisition for conservation assessments: is the effort worth it?

    Hermoso, Virgilio; Kennard, Mark J; Linke, Simon

    2013-01-01

    When identifying conservation priorities, the accuracy of conservation assessments is constrained by the quality of data available. Despite previous efforts exploring how to deal with imperfect datasets, little is known about how data uncertainty translates into errors in conservation planning outcomes. Here, we evaluate the magnitude of commission and omission error, effectiveness and efficiency of conservation planning outcomes derived from three datasets with increasing data quality. We demonstrate that investing in data acquisition might not always be the best strategy as the magnitude of errors introduced by new sites/species can exceed the benefits gained. There was a trade-off between effectiveness and efficiency due to poorly sampled rare species. Given that data acquisition is limited by the high cost and time required, we recommend focusing on improving the quality of data for those species with the highest level of uncertainty (rare species) when acquiring new data.

    Mohd Najwadi Yusoff

    2015-05-01

    Full Text Available Mozilla Corporation has recently released a Linux-based open source operating system, namely Firefox OS. The arrival of this Firefox OS has created new challenges, concentrations and opportunities for digital investigators. Currently, Firefox OS is still not fully supported by most of the existing mobile forensic tools. Even when the phone is detected as Android, only pictures from removable memory was able to be captured. Furthermore, the internal data acquisition is still not working. Therefore, there are very huge opportunities to explore the Firefox OS on every stages of mobile forensic procedures. This paper will present an approach for mobile forensic data acquisition in a forensically sound manner from a Firefox OS running device. This approach will largely use the UNIX dd command to create a forensic image from the Firefox OS running device. Apart from that, performance measurement will be made to find the best block size for acquisition process in Firefox OS.

    Full Text Available The paper presents a comparison of selected models from area of artificial neural networks and decision trees in relation with actualconditions of foundry processes. The work contains short descriptions of used algorithms, their destination and method of data preparation,which is a domain of work of Data Mining systems. First part concerns data acquisition realized in selected iron foundry, indicating problems to solve in aspect of casting process modeling. Second part is a comparison of selected algorithms: a decision tree and artificial neural network, that is CART (Classification And Regression Trees and BP (Backpropagation in MLP (Multilayer Perceptron networks algorithms.Aim of the paper is to show an aspect of selecting data for modeling, cleaning it and reducing, for example due to too strong correlationbetween some of recorded process parameters. Also, it has been shown what results can be obtained using two different approaches:first when modeling using available commercial software, for example Statistica, second when modeling step by step using Excel spreadsheetbasing on the same algorithm, like BP-MLP. Discrepancy of results obtained from these two approaches originates from a priorimade assumptions. Mentioned earlier Statistica universal software package, when used without awareness of relations of technologicalparameters, i.e. without user having experience in foundry and without scheduling ranks of particular parameters basing on acquisition, can not give credible basis to predict the quality of the castings. Also, a decisive influence of data acquisition method has been clearly indicated, the acquisition should be conducted according to repetitive measurement and control procedures. This paper is based on about 250 records of actual data, for one assortment for 6 month period, where only 12 data sets were complete (including two that were used for validation of neural network and useful for creating a model.

  17. Design choices for control and data acquisition in RFX

    Data acquisition and control were developed in RFX in the late 1980s, by adopting a split hardware approach based on the time characteristics of signals. Industrial-type programmable controllers were used for plant control and monitoring, computers with CAMAC front-end for data acquisition and timing. The shutdown to rebuild the machine power supply and to modify the magnetic structure offers the opportunity to update part of the ageing system to state-of-the-art technology. The concepts and the criteria for the updating of the system are reported and discussed in the paper. First of all, the system will fully exploit the multi-platform approach of the MDSPlus data acquisition package, which allows the use of distributed processors to handle data acquisition locally. CompactPCI has been selected as the hardware standard, due to its high performance, perspectives and low cost. A new timing system is also under development. This is engineered in CompactPCI format and is fully compatible with the existing CAMAC-based timing system. The control and monitoring system will rely, as far as possible, on hardware and software standards established in industrial automation, such as field-buses at cell automation level and industrial Ethernet at factory automation level

  10. Geofencing-Based Localization for 3d Data Acquisition Navigation

    Nakagawa, M.; Kamio, T.; Yasojima, H.; Kobayashi, T.

    2016-06-01

    Users require navigation for many location-based applications using moving sensors, such as autonomous robot control, mapping route navigation and mobile infrastructure inspection. In indoor environments, indoor positioning systems using GNSSs can provide seamless indoor-outdoor positioning and navigation services. However, instabilities in sensor position data acquisition remain, because the indoor environment is more complex than the outdoor environment. On the other hand, simultaneous localization and mapping processing is better than indoor positioning for measurement accuracy and sensor cost. However, it is not easy to estimate position data from a single viewpoint directly. Based on these technical issues, we focus on geofencing techniques to improve position data acquisition. In this research, we propose a methodology to estimate more stable position or location data using unstable position data based on geofencing in indoor environments. We verify our methodology through experiments in indoor environments.

    The LHCb Data Acquisition system reads data from over 300 read-out boards and distributes them to more than 1500 event-filter servers. It uses a simple push-protocol over Gigabit Ethernet. After filtering, the data is consolidated into files for permanent storage using a SAN-based storage system. Since the beginning of data-taking many lessons have been learned and the reliability and robustness of the system has been greatly improved. We report on these changes and improvements, their motivation and how we intend to develop the system for Run 2. We also will report on how we try to optimise the usage of CPU resources during the running of the LHC ('deferred triggering') and the implications on the data acquisition.

  16. Data acquisition backbone core DABC release v1.0

    The new experiments at FAIR require new concepts of data acquisition systems for the distribution of self-triggered, time stamped data streams over high performance networks for event building. The Data Acquisition Backbone Core (DABC) is a general purpose software framework developed for the implementation of such data acquisition systems. A DABC application consists of functional components like data input, combiner, scheduler, event builder, filter, analysis and storage which can be configured at runtime. Application specific code including the support of all kinds of data channels (front-end systems) is implemented by C++ program plug-ins. DABC is also well suited as environment for various detector and readout components test beds. A set of DABC plug-ins has been developed for the FAIR experiment CBM (Compressed Baryonic Matter) at GSI. This DABC application is used as DAQ system for test beamtimes. Front-end boards equipped with n-XYTER ASICs and ADCs are connected to read-out controller boards (ROC). From there the data is sent over Ethernet (UDP), or over optics and PCIe interface cards into Linux PCs. DABC does the controlling, event building, archiving and data serving. The first release of DABC was published in 2009 and is available under GPL license.

  6. 'RADAR': The standard Euratom unattended data acquisition system

    Automatic, unattended data acquisition is becoming an essential and more common part of safeguards. The reasons are the growing number of large plants with automatic handling of material, the rising amount of material and the continuous need to optimize scarce human inspection resources. This paper describes the status of the latest development, the software program package RADAR (Remote Acquisition of Data and Review), which aims at standardizing the unattended NDA systems in use by the Euratom Safeguards Office (ESO). ESO has started to use unattended systems particularly in the large bulk handling facilities more than a decade ago. As a result of the learning process, the Windows NT based RADAR has now been developed in house with close commercial cooperation and has already been successfully installed in facilities in several EU member states. The data acquisition layer of RADAR can deal with a large variety of sensors. The technical review program, Global Surveyor, allows to see the state of health of the system and to check the completeness of acquired data. The generic data analysis program CRISP with its user interface SEAT aids the inspector in finding safeguards conclusions. RADAR also allows the transmission of data remotely, either to a central inspector's office on a large site or to headquarters in Luxembourg. The state of the various components is also discussed in detail. (author)

  7. High speed tomographic optical data acquisition system for combustion research

    Optical tomography provides a means for obtaining spatially resolved measurements from line-of-sight data. Classical flow visualization approaches such as shadowgraphy, schlieren and interferometry provide information about physical observables averaged along the path of the probe beam. Locally resolved measurements cannot be obtained from such data sets, except for axially symmetric or two-dimensional flows. Tomography has been applied to medical and industrial applications. Particularly in medicine, tomographic diagnostics are well developed. Since medical objects tend to be stationary, data acquisition times need not be very rapid and sequential acquisition of projections is sufficient. In fluid mechanics no such luxury is usually allowed, since the most interesting flows are unsteady and rapidly developing. This requires that tomographic data acquisition systems have a very short response time and all projections must be collected in such a short time that the flow is essentially frozen. A new optical architecture is described that is capable providing 36 equally spaced projections about a 180 degree arc in 300 μsec. Each projection passes through a three inch diameter, three inch high cylinder, allowing a full three-dimensional reconstruction of the flow in that region. Holographic interferometry allows direct measurement of optical phase along the pathlength. From these data, the flow may be reconstructed using any of the available reconstruction techniques. The design of the optical apparatus is described, followed by an outline of the experiment, the data reduction scheme and the results obtained with this method

  8. Information management system breadboard data acquisition and control system.

    Mallary, W. E.

    1972-01-01

    Description of a breadboard configuration of an advanced information management system based on requirements for high data rates and local and centralized computation for subsystems and experiments to be housed on a space station. The system is to contain a 10-megabit-per-second digital data bus, remote terminals with preprocessor capabilities, and a central multiprocessor. A concept definition is presented for the data acquisition and control system breadboard, and a detailed account is given of the operation of the bus control unit, the bus itself, and the remote acquisition and control unit. The data bus control unit is capable of operating under control of both its own test panel and the test processor. In either mode it is capable of both single- and multiple-message operation in that it can accept a block of data requests or update commands for transmission to the remote acquisition and control unit, which in turn is capable of three levels of data-handling complexity.

In this concept any data filtering is done behind the network. Therefore the network must achieve up to 1 GByte/s bi-directional data transfer per node. Detailed simulations have been done to optimize scheduling mechanisms for such event building networks. For real performance tests InfiniBand has been chosen as one of the fastest available network technology. The measurements of network event building have been performed on different Linux clusters from four to over hundred nodes. Several InfiniBand libraries have been tested like uDAPL, Verbs, or MPI. The tests have been integrated in the data acquisition backbone core software DABC, a general purpose data acquisition library. Detailed results are presented. In the worst cases (over hundred nodes) 50% of the required bandwidth can be already achieved. It seems possible to improve these results by further investigations

    A package for the transport and long-term storage of irradiated fuel of research reactors is been developed by Argentina, Brazil and Chile through a regional cooperation project. In the scope of this project, a half-scale model of the package was designed, constructed and tested according to the IAEA regulations for the transport of radioactive materials. In order to acquire the temperatures developed during the prescribed thermal test, a dedicated data acquisition system was developed by the Centro de Desenvolvimento da Tecnologia Nuclear. The system was developed using the InduSoft Web Studio, a software platform which allows the development of HMI (Human Machine Interface) applications, and SCADA (Supervisory Control and Data Acquisition), a computer controlled system that monitors and controls industrial processes. The acquisition system's main components are the power supply source, two conversers, and the supervisor software InduSoft Web Studio. The sensors used were 5 m long Type K thermocouples with mineral isolation. Although developed for a specific application, the system can be used for temperature acquisition of diverse industrial processes. (author)

  12. Porting VIRTEX4 data acquisition design to SPARTAN6 FPGA

    Complete text of publication follows. The Atomki's Virtex 4 based 4 channel data acquisition card (LIR) card was used in many applications (miniPET-II, miniPET-III, data acquisition system for the multichannel plate installed at the ECR lab). The goal of the work was to improve the LIR using a higher performance FPGA (Spartan6 Trenz module). The Trenz module based system also supports ADC channels up to 16 channels. This work also implied the porting of the Virtex4 based VHDL code to Spartan 6. Further advantage of the proposed system, besides the improvement in the number of ADC channels, that the Spartan6 FPGA is able to run more complex digital signal processing algorithms than the Virtex 4 FPGA. Easy access to the control parameters (via serial interface or Ethernet), flexibility and high performance were considered during the development. SPARTAN6 FPGA based data acquisition provides more facilities than the VIRTEX4 based. SPARTAN6 is a newer generation of XILINX’s FPGAs, which excellent into the high-speed data acquisition. We ported the HDL code, which runs on LIR module (VIRTEX4 based), to the Trenz module (SPARTAN6 based). The main parts of the whole program code are the command line interpreter, GMII interface, DHCP process, ARP process and the data read out. Those parts were implemented by picoblaze embedded system. Figure 1 shows the command line interpreter process in the Hyper Terminal. The command line interpreter communicates with the PC via serial port. In addition, the AdamIOSetting software also use the serial communication, which was created to the VIRTEX FPGA based data collector. In the Wireshark network analyzer software we examined the DHCP and ARP process and using the AdamIOSettings software we tested the data read out from the flash memory of FPGA board. Figure 2 shows the AdamIOSettings program. Acknowledgements. This work was supported by the ENIAC CSI Project (No.120209).

  14. Multi-channel data acquisition system with absolute time synchronization

    We present a low-cost, stand-alone global-time-synchronized data acquisition system. Our prototype allows recording up to four analog signals with a 16-bit resolution in variable ranges and a maximum sampling rate of 1000 S/s. The system simultaneously acquires readouts of external sensors e.g. magnetometer or thermometer. A complete data set, including a header containing timestamp, is stored on a Secure Digital (SD) card or transmitted to a computer using Universal Serial Bus (USB). The estimated time accuracy of the data acquisition is better than ±200 ns.

  16. Development of data acquisition software for VME based system

    A data acquisition system for VME has been developed for use in accelerator based experiments. The development was motivated by the growing demand for higher throughput in view of the increasing size of experiments. VME based data acquisition system provides a powerful alternative to CAMAC standards on account of higher readout speeds (100 ns/word) resulting in reduced dead time. Further, high density VME modules are capable of providing up to 640 channels in a single VME crate with 21 slots. The software system LAMPS, earlier developed for CAMAC based system and used extensively in our laboratory and elsewhere has been modified for the present VME based system. The system makes use of the VME library to implement Chain Block Transfer Readout (CBLT) and gives the option of both Polling and Interrupt mode to acquire data. Practical throughput of ∼ 250 ns/word in zero suppressed mode has been achieved. (author)

The school, which consists 50% of lectures and 50% of exercises, is a unique opportunity for students to learn how to implement a good trigger and to design a data-acquisition system for today’s increasingly complex experiments. Thanks to the tutored exercises, students can gain hands-on experience of trigger systems, data-acquisition hardware and software, and data-transfer technologies.

  18. Experiment data acquisition and analysis system. Vol. 1

    The Experiment Data Acquisition and Analysis System EDAS was created to acquire and analyze data collected in experiments carried out at the heavy ion accelerator UNILAC. It has been available since 1975 and has become the most frequently used system for evaluating experiments at GSI. EDAS has undergone constant development, and the many enhancements make this completely revised third edition of the EDAS manual necessary. EDAS consists of two sub-systems: GOLDA for experimental data acquisition on PDP-11's and SATAN mainly for off-line analysis in replay mode on large IBM mainframes. The capacity of one IBM 3081 CPU is mainly dedicated to EDAS processing and is almost fully utilized by this application. More than 200 users from GSI as well as from collaborating laboratories and universities use SATAN in more than 100 sessions daily needing 10 to 20 hours of user CPU time. EDAS is designed as an open system. (orig./HSI)

  19. Autonomous data acquisition system for Paks NPP process noise signals

    A prototype of a new concept noise diagnostics data acquisition system has been developed recently to renew the aged present system. This new system is capable of collecting the whole available noise signal set simultaneously. Signal plugging and data acquisition are performed by autonomous systems (installed at each reactor unit) that are controlled through the standard plant network from a central computer installed at a suitable location. Experts can use this central unit to process and archive data series downloaded from the reactor units. This central unit also provides selected noise diagnostics information for other departments. The paper describes the hardware and software architecture of the new system in detail, emphasising the potential benefits of the new approach. (author)

  20. Measured radioactivity data acquisition and evaluation system (REA)

    In Germany, authorities in the Federal States are obliged to monitor the environment for radioactivity. Various institutions run radioactivity measurements for this purpose. The measured results are made available to the competent authorities in a variety of ways. Computer systems are now used for central collection and evaluation of these data. LfU has developed a concept to support by DP technologies also the procedures between the measurement site and the central authority. This facilitates data acquisition and speeds up data transmission. The REA concept will streamline procedures and improve data quality. (orig.)

  3. Modular software for MAST multi-technology data acquisition system

    The MAST (Mega-Amp Spherical Tokamak) data acquisition system is being radically upgraded. New hardware with completely different control interface and logic has been installed on all system levels from front-end devices to plant control. MAST plant control has been moved from VMS to a Windows-based OPC system. Old CAMAC and VME units are being replaced by cPCI and PXI units. A number of CAMAC crates have been upgraded with new Ethernet controllers supporting useful front-end devices. The upgrade is being performed without disturbing operations; the data acquisition units are being replaced gradually. Such an upgrade is possible due to the structure of the MAST data acquisition system which is build as a set of autonomous units, each one controlled by a computer. Modern computers are capable of controlling several units, and this has been the major opportunity and challenge because it radically changes the unit control logic. As a result practically all system components had to be redesigned. The new unit software is a step in system evolution towards greater flexibility and universality. Each unit can now manage multiple data files, possibly with different formats, and many units can be hosted on the same computer. This feature is provided by a message proxy server. Each unit is controlled independently and transparently, exactly like a stand-alone unit. A message interface has been modified for consistent handling of new functions. The unit software supports event-triggered and real-time data acquisition at the system level. New software has been developed for a number of new hardware devices, and the device modules for all usable old devices have been rewritten to operate with the new control interface. The new software allows units to be upgraded even during operations. The system structure and logic provide easy extension. The system as a whole or system design elements could also be used on other fusion facilities.

  4. Research of bunch by bunch data acquisition system in SSRF

    Background: In order to improve the synchrotron performance in the constant current mode, attentions should be paid to problems such as non-linear beam dynamics, broadband beam impedance, and position disturbance, etc. Purpose: To address these problems, a bunch by bunch data acquisition system (BBDAQ) is implemented for real-time bunch position monitoring, as well as the off-line data analysis for the Shanghai Synchrotron Radiation Facility (SSRF) storage ring. It can be applied to optimize new equipment impedance, filling pattern, injection mode, and raise threshold value of current instability. Methods: This BBDAQ developed at SSRF consists a RF front end to filter and expand bunch signal to 2 ns, a data acquisition and processing card to sample bunch signal with four 125-MHz ADCs, which make an equivalent 500-MHz sampling rate, and the EPICS for post-processing to give bunch position and tune value. Results: Online experimental results show that the system can measure bunch by bunch position and tune value successfully. Conclusion: The development of bunch by bunch data acquisition system provides an efficient tool to analyze beam impedance, coupling instability, nonlinear dynamics. It makes further improvement of synchrotron performance visible. (authors)

    2011-01-01

    The Dark Energy Camera (DECam) data acquisition and control system is called the Survey Image System Process Integration (SISPI). Implemented as a distributed multi-processor system, SISPI consists of a set of processes that will coordinate and perform image acquisition and deliver images to the data management system for processing. Separate processes for instrument control, image building and analysis, image acquisition and observatory control are built on top of an infrastructure layer that provides message passing and communications. Additional system components include a flexible configuration system and the facility database. The command protocol is implemented in Python using a client-server design pattern derived from the SML and SCLN communications software developed at CTIO. A publish-subscribe model has been added to support the distribution of telemetry data and alarm messages. The design of the graphical user interfaces follows the Model-View-Controller approach to distinguish between the actual information and the graphical representation of the data. We will present the software architecture of the SISPI system and report on the current status of the project.

  6. A versatile spatial resolution enhancement method for data acquisition

    While acquiring specific physical properties within a targeted area, spatial resolution of hardware is usually one of the major limitations that affects the precision of data acquisition. Though measured results with higher spatial resolution are always desired, adequate configuration of hardware setups sometimes implies higher cost or longer acquisition time. In this study, a versatile resolution enhancement method is proposed to improve the sampling resolution. An efficient algorithm is used to convert the lower-resolution data into higher-resolution approximation. Three different engineering applications are used to verify the effectiveness of the proposed method. From the arithmetic results, the spatial sampling resolution can be greatly improved without trading-off the operating time. (paper)

  7. New data acquisition system for the lujan center

    To meet the data acquisition requirements for six new neutron scattering instruments at the Los Alamos Science Center (LANSCE), we are building systems using Web tools, commercial hardware and software, software developed by the controls community, and custom hardware developed by the neutron scattering community. To service these new instruments as well as seven existing instruments, our data acquisition system needs common software and hardware core capabilities and the means to flexibly integrate them while differentiating the needs of the diverse instrument suite. Neutron events are captured and processed in VXI modules while controls for sample environment and beam line setup are processed with PCs. Typically users access the system through web browsers.

An interprocess communication system (IPCS) allows programs to communicate with one another in a standard manner regardless of program location in the network or of operating system and hardware differences. We discuss the design and implementation of this data acquisition system with particular emphasis on the coordination model and the IPCS. 5 refs., 3 figs

The RPDA development has incorporated multiple high-temperature (225C) electronic components within a compact co-fired ceramic Multi-Chip-Module (MCM) package. This assembly is suitable for use in down-hole oil and gas applications. The RPDA module is programmable to support a wide range of functionality. Specifically this project has demonstrated functional integrity of the RPDA package and internal components, as well as functional integrity of the RPDA configured to operate as a Multi-Channel Data Acquisition Controller. This report reviews the design considerations, electrical hardware design, MCM package design, considerations for manufacturing assembly, test and screening, and results from prototype assembly and characterization testing.

  10. Acquisition of gamma camera and physiological data by computer

    We have designed, implemented, and tested a new Research Data Acquisition System (RDAS) that permits a general purpose digital computer to acquire signals from both gamma camera sources and physiological signal sources concurrently. This system overcomes the limited multi-source, high speed data acquisition capabilities found in most clinically oriented nuclear medicine computers. The RDAS can simultaneously input signals from up to four gamma camera sources with a throughput of 200 kHz per source and from up to eight physiological signal sources with an aggregate throughput of 50 kHz. Rigorous testing has found the RDAS to exhibit acceptable linearity and timing characteristics. In addition, flood images obtained by this system were compared with flood images acquired by a commercial nuclear medicine computer system. National Electrical Manufacturers Association performance standards of the flood images were found to be comparable

    DART is the high speed, Unix based data acquisition system being developed by the Fermilab Computing Division in collaboration with eight High Energy Physics Experiments. This paper describes DART run-control which implements flexible, distributed, extensible and portable paradigms for the control and monitoring of data acquisition systems. We discuss the unique and interesting aspects of the run-control - why we chose the concepts we did, the benefits we have seen from the choices we made, as well as our experiences in deploying and supporting it for experiments during their commissioning and sub-system testing phases. We emphasize the software and techniques we believe are extensible to future use, and potential future modifications and extensions for those we feel are not

  12. ALICE - A computer program for nuclear data acquisition

    This manual contains the users guide and the program documentation for the ALICE data acquisition system. The ALICE Users Guide, which is contained in part 1 of the manual, can be read independently of the program documentation in part 2. The ALICE program is written in the interpretive language NODAL. Due to the inherent slow execution speed of interpreted code time-consuming tasks such as non-linear least squares peak fitting cannot be implemented. On the other hand the special features of the NODAL language have made possible facilities in ALICE which hardly could have been realized by, e.g. a FORTRAN program. The complete system can be divided in two parts, i) the ALICE program written in NODAL, and ii) a data acquisition package which logically represents an extension of the SINTRAN III operating system. The system is thus portable to other NORD- 10/100 installations provided that the floating hardware is 48 bits. (Auth.)

  16. Wireless Data Acquisition of Transient Signals for Mobile Spectrometry Applications.

    Trzcinski, Peter; Weagant, Scott; Karanassios, Vassili

    2016-05-01

    Wireless data acquisition using smartphones or handhelds offers increased mobility, it provides reduced size and weight, it has low electrical power requirements, and (in some cases) it has an ability to access the internet. Thus, it is well suited for mobile spectrometry applications using miniaturized, field-portable spectrometers, or detectors for chemical analysis in the field (i.e., on-site). There are four main wireless communications standards that can be used for wireless data acquisition, namely ZigBee, Bluetooth, Wi-Fi, and UWB (ultra-wide band). These are briefly reviewed and are evaluated for applicability to data acquisition of transient signals (i.e., time-domain) in the field (i.e., on-site) from a miniaturized, field-portable photomultiplier tube detector and from a photodiode array detector installed in a miniaturized, field-portable fiber optic spectrometer. These are two of the most widely used detectors for optical measurements in the ultraviolet-visible range of the spectrum. A miniaturized, 3D-printed, battery-operated microplasma-on-a-chip was used for generation of transient optical emission signals. Elemental analysis from liquid microsamples, a microplasma, and a handheld or a smartphone will be used as examples. Development and potential applicability of wireless data acquisition of transient optical emission signals for taking part of the lab to the sample types of mobile, field-portable spectrometry applications will be discussed. The examples presented are drawn from past and ongoing work in the authors' laboratory. A handheld or a smartphone were used as the mobile computing devices of choice. PMID:27006023

    The MIPP TPC is the largest contributor to the MIPP event size by far. Its readout system and electronics were designed in the 1990's and limit it to a readout rate of 60 Hz in simple events and {approx} 20 Hz in complicated events. With the readout chips designed for the ALICE collaboration at the LHC, we propose a low cost effective scheme of upgrading the MIPP data acquisition speed to 3000 Hz.

  1. Data acquisition system for light-ion irradiation creep experiment

    Software was developed for a PDP11V/03-based data acquisition system to support the Light-Ion Irradiation Creep Experiment installed at the University of Washington Tandem Van de Graaff Accelerator. The software consists of a real-time data acquisition and storage program, DAC04, written in assembly language. This program provides for the acquisition of up to 30 chennels at 100 Hz, data averaging before storage on disk, alarming, data table display, and automatic disk switching. All analog data are acquired via an analog-to-digital converter subsystem having a resolution of 14 bits, a maximum throughput of 20 kHz, and an overall system accuracy of +-0.01%. These specifications are considered essential for the long-term measurement of irradiation creep strains and temperatures during the light-ion bombardment of irradiation creep specimens. The software package developed also contains a collection of FORTRAN programs designed to monitor a test while in progress. These programs use the foreground/background feature of the RT-11 operating system. The background programs provide a variety of services. The program, GRAFTR, allows transient data (i.e., prior to averaging) to be graphed at the graphics terminal. The program, GRAFAV, allows averaged data to be read from disk and displayed graphically at the terminal. The program, TYPAV, reads averaged data from disk and displays it at the terminal in tabular form. Other programs allow text messages to be written to disk, read from disk, and allow access to DAC04 initialization data. 5 figures, 18 tables

  3. A microprocessor-based power control data acquisition system

    The project reported deals with one of the aspects of power plant control and management. In order to perform optimal distribution of power and load switching, one has to solve a specific optimization problem. In order to solve this problem one needs to collect current and power expenditure data from a large number of channels and have them processed. This particular procedure is defined as data acquisition and it constitutes the main topic of this project. A microprocessor-based data acquisition system for power management is investigated and developed. The current and power data of about 100 analog channels are sampled and collected in real-time. These data are subsequently processed to calculate the power factor (cos phi) for each channel and the maximum demand. The data is processed by an AMD 9511 Arithmetic Processing Unit and the whole system is controlled by an Intel 8080A CPU. All this information is then transfered to a universal computer through a synchronized communication channel. The optimization computations would be performed by the high level computer. Different ways of performing the search of data over a large number of channels have been investigated. A particular solution to overcome the gain and offset drift of the A/D converter, using software, has been proposed. The 8080A supervises the collection and routing of data in real time, while the 9511 performs calculation, using these data. (Author)

The key component of the presented solution is a configurable microcontroller-based device with an integrated USB transceiver and a 12-bit analogue-to-digital converter (ADC. The presented embedded DAQ device contains a preloaded program (firmware that enables easy acquisition and generation of analogue and digital signals and data transfer between the device and the application running on a PC via USB bus. This device has been developed as a USB human interface device (HID. This USB class is natively supported by most of the operating systems and therefore any installation of additional USB drivers is unnecessary. The input/output peripheral of the presented device is not static but rather flexible, and could be easily configured to customised needs without changing the firmware. When using the developed configuration utility, a majority of chip pins can be configured as analogue input, digital input/output, PWM output or one of the SPI lines. In addition, LabVIEW drivers have been developed for this device.

  5. CAMAC data acquisition system based on micro VAXII

    The CAMAC data acquisition system based on Micro VAXII Computer provides high-speed, Zero-suppressed, and 256-parameter CAMAC acquisition. It consists of three parts: control logic unit, CAMAC readout system and host computer system. When the control logical unit is triggered by external electronic selection signal, it produces a pilot signal to keep all of the parameters of a particular event together. Event-model data have been collected by using a CAMAC Fast Crate controller. The host computer system, in hard environment, is equipped with certain peripheral device. It includes the following: 1. at least two M990 GCR, 6250B/inch, magnetic tape driver operating at 75 inches per second or faster; 2. a Tektronix 4014 storage scope; 3. a laser printer, LND3-AE or copier which is capable of making hard-copies of Tektronix 4014 screen; 4. a control console device and a line printer; 5. x-press color graphics terminal; 6. DEC network. When the system is in real-time acquisition, it is able, on-line, to handle and analyse data stream, to monitor and control experiment and to display dynamically spectra on the Tektronix 4014

  6. Data acquisition and processing software package for Medipix2

    The semiconductor pixel detector Medipix2 [1] (256x256 square pixels, 55x55 μm2 each) is a superior imaging device in terms of spatial resolution, linearity and dynamic range. This makes it suitable for various applications such as radiography, neutronography, and micro-tomography. The software package for acquisition and data processing has been developed to control and manage complex measurements. The solution features an open and very flexible modular architecture with custom made plugin support. Plugins can control parts of the acquisition system as well as perform real-time data processing and use these results as feedback for controlling further steps of measurements. This allows us to control, e.g. data acquisition, position and rotation of the sample (stepper motors), source parameters, temperature, etc. in a synchronized way. An example is the adaptive tomography plugin which adaptively controls the measurement and benefits from preprocessing performed by other plugins such as the beam-hardening correction of measured projections

    Rosser, Robert S.; Rahman, Hasan H.

    1993-01-01

    Developed for the NASA Johnson Space Center and Life Sciences Directorate by GE Government Services, the Microcomputer Integrated Real-time Acquisition Ground Equipment (MIRAGE) system is a portable ground support system for Spacelab life sciences experiments. The MIRAGE system can acquire digital or analog data. Digital data may be NRZ-formatted telemetry packets of packets from a network interface. Analog signal are digitized and stored in experimental packet format. Data packets from any acquisition source are archived to a disk as they are received. Meta-parameters are generated from the data packet parameters by applying mathematical and logical operators. Parameters are displayed in text and graphical form or output to analog devices. Experiment data packets may be retransmitted through the network interface. Data stream definition, experiment parameter format, parameter displays, and other variables are configured using spreadsheet database. A database can be developed to support virtually any data packet format. The user interface provides menu- and icon-driven program control. The MIRAGE system can be integrated with other workstations to perform a variety of functions. The generic capabilities, adaptability and ease of use make the MIRAGE a cost-effective solution to many experimental data processing requirements.

    Many high energy physics experiments (Auger, IceCube, NEMO, Km3Net) currently taking data or planned in the near future consist of big and sparse detectors that acquire a huge amount of data. This kind of topology requires the ability to acquire physics information in different places of the detector and correlate them using the occurrence time, usually with a sub-ns precision. The architecture described here provides a real-time data transport layer, used to implement the data acquisition system for the NEMO experiment, and consists of a synchronous link with fixed and deterministic latency. The system clock, distributed at every level of the apparatus, has been derived by the signals provided by a GPS receiver during the operating configuration. The aim of this contribution is to give an overview of the NEMO electronic system: the underwater electronics sample signals from photomultipliers and acquires slow-control data from both oceanographic instruments and dedicated sensors, allowing to monitor the operational conditions of the apparatus. The whole data are sent to the laboratory through a fully bi-directional fiber optic link. On-shore the data are received by dedicated boards that distribute them to the first-level trigger and to the slow-control system. A description of the different stages of data acquisition and transport will be given.

  11. A new compiler for the GANIL Data Acquisition description

    An important feature of the GANIL Data Acquisition System is the description of the experiments by means of a language developed at GANIL. The philosophy is to attribute to each element (parameters, spectra, etc) an operational name which will be used at any level of the system. This language references a library of modules to free the user from the technical details of the hardware. This compiler has been recently entirely re-developed using technologies as the object-oriented language (C++) and object-oriented software development method and tool. This enables us to provide a new functionality or to support a new electronic module within a very short delay and without any deep modification of the application. A new Dynamic Library of Modules has been also developed. Its complete description is available on the GANIL WEB site http://ganinfo.in2p3.fr/acquisition/homepage.html. This new compiler brings a lot of new functionalities, among which the most important is the notion of 'register' whatever the module standard is. All the registers described in the module provider's documentation can now be accessed by their names. Another important new feature is the notion of 'function' that can be executed on a module. Also a set of new instructions has been implemented to execute commands on CAMAC crates. Another possibility of this new compiler is to enable the description of specific interfaces with GANIL Data Acquisition System. This has been used to describe the coupling of the CHIMERA Data Acquisition System with the INDRA one through a shared memory in the VME crate. (authors)

  14. Upgrade issues in FTU control, data acquisition and management

    Highlights: • We report the upgrades that have been done in FTU control, data acquisition and management. • The technologies adopted: emulation, virtualization and failover. • New data acquisition systems of FTU diagnostic systems are described. • The issue of large dataset produced by devices like Fast camera is discussed. • Additional hardware/software resources for FTU data handling system are reported. - Abstract: FTU is operating since 1989, thus its hardware and software infrastructure must be continuously updated to preserve its efficiency and reliability. This issue can be addressed by means of two distinct approaches: (i) the migration to an emulated environment enabling the use of modern hardware on virtualized standard servers to keep the operating systems full functionality and the application environment; (ii) the porting of the complete system architecture to new hardware, new operating systems, and new programming languages. This paper reports on the upgrades implemented on FTU in the last two years using both these approaches including the new system to acquire and store the image frames of FTU plasma discharges through a Photron FASTCAM SA4 camera. Regarding data handling, a small Linux high performance computing system (1TFlops) with a high performance data storage system (100 TB) in InfiniBand DDR infrastructure has been installed as data analysis, modelling and archive cluster for the next three years of FTU experimental activities

  15. Floating data acquisition system for microwave calorimeter measurements on MTX

    Sewall, N.R.; Meassick, S. (Lawrence Livermore National Lab., CA (USA))

    1989-09-13

    A microwave calorimeter has been designed for making 140-GHz absorption measurements on the MTX. Measurement of the intensity and spatial distribution of the FEL-generated microwave beam on the inner wall will indicate the absorption characteristics of the plasma when heated with a 140 GHz FEL pulse. The calorimeter works by monitoring changes of temperature in silicon carbide tiles located on the inner wall of the tokamak. Thermistors are used to measure the temperature of each tile. The tiles are located inside the tokamak about 1 cm outside of the limiter radius at machine potential. The success of this measurement depends on our ability to float the data acquisition system near machine potential and isolate it from the rest of the vault ground system. Our data acquisition system has 48 channels of thermistor signal conditioning, a multiplexer and digitizer section, a serial data formatter, and a fiber-optic transmitter to send the data out. Additionally, we bring timing signals to the interface through optical fibers to tell it when to begin measurement, while maintaining isolation. The receiver is an HP 200 series computer with a serial data interface; the computer provides storage and local display for the shot temperature profile. Additionally, the computer provides temporary storage of the data until it can be passed to a shared resource management system for archiving. 2 refs., 6 figs.

  1. The data acquisition system for the aCORN experiment

    Dewey, Maynard; aCORN Collaboration

    2015-10-01

    The aCORN experiment measures the angular correlation between the electron and neutrino emitted in free neutron beta decay, via an electron-proton momentum correlation asymmetry. Doing so requires detecting neutron beta decay protons and electrons in coincidence. Protons are detected with a surface barrier detector while electrons are detected with a large scintillator whose light output is parceled into 19 photomultiplier tubes. Additionally there are eight scintillators that detect backscattered electrons so that these events may be removed from the data stream. This talk will discuss the novel data acquisition system (both hardware and software) that has been developed to handle the high throughput rates observed. NIST, DOE and NSF.

  2. A scalable data acquisition system using the chorus operating system

    A Scalable Data Acquisition System has been designed using Chorus, a modular distributed real-time operating system and serial point-links. The SDAS is based on data-driven clients and servers which allow scability of the software through their distribution and hierarchy. The communication between clients and servers is under-pinned by the Inter Process Communication (IPC) facilities of the Chorus operating system. The IPC offers communication indirection; the communication interface of clients and servers remains constant across a distributed system independent of the placement of process on processors. The scalability of the hardware is achieved using point-to-point serial links. (author)

  4. Analogues between tuning TCP for Data Acquisition and Datacenter Networks

    Jereczek, G; Malone, D

    2015-01-01

    A many-to-one communication pattern is present both in Data Acquisition (DAQ) and datacenter networks. The problem arising from this pattern is widely known in the literature as incast and can be observed as TCP throughput collapse. It is a result of overloading the switch buffers, when a specific node in a network requests data from multiple sources. This paper provides two contributions. First, we confirm that there are strong analogies between the TCP behavior in DAQ and datacenter networks. Second, we evaluate different proposals from datacenter for application in DAQ to improve performance and reduce buffer requirements.

  10. The IAEA universal nondestructive assay data acquisition platform (UNAP)

    The IAEA Department of Safeguards is developing a new series of instruments for safeguarding nuclear material. The Universal NDA Data Acquisition Platform (UNAP) will be the next generation data acquisition system attended and unattended non-destructive assay measurement equipment. The primary goal of the UNAP development is for the new module to become the IAEA standard and replace existing Non-Destructive Assay (NDA) modules such as the JSR-12, the MiniGrand, the Advanced Multiplicity Shift Register (AMSR), and the JSR-14. The inputs to the UNAP will be a super-set of the existing inputs of all these previous modules with flexibility to anticipate future developments. The core measurement capabilities of the UNAP include three multiplicity shift registers clocked at 50 MHz, an eight channel combination scalar-derandomizer with output to one of the shift registers, dual current mode measurement channels with 30 femto-ampere resolution, a list mode channel with 100 nanosecond resolution, four programmable threshold single channel analyzers (SCA), a 4-20 mA channel, and several discrete digital inputs and isolated contact closure outputs. All measurement data is acquired and reduced by a Freescale PowerQUICC processor and is locally stored in a 16 GByte solid state drive. The UNAP will authenticate and encrypt the data for transmission across the 100-BaseT Ethernet interface to the data acquisition system. In this paper the IAEA will provide more detailed information concerning the operational and performance characteristics of the UNAP instrument. We will share knowledge from the rapid-development utilizing the commercial cPCI bus. We will provide a status of the instrument development from Los Alamos and from the processor and commercial UNAP vendors and updates to our target milestones. Finally, we will provide information on how the UNAP will be used with future safeguards systems in large numbers at nuclear facilities

  11. Wireless Data-Acquisition System for Testing Rocket Engines

    Lin, Chujen; Lonske, Ben; Hou, Yalin; Xu, Yingjiu; Gang, Mei

    2007-01-01

    A prototype wireless data-acquisition system has been developed as a potential replacement for a wired data-acquisition system heretofore used in testing rocket engines. The traditional use of wires to connect sensors, signal-conditioning circuits, and data acquisition circuitry is time-consuming and prone to error, especially when, as is often the case, many sensors are used in a test. The system includes one master and multiple slave nodes. The master node communicates with a computer via an Ethernet connection. The slave nodes are powered by rechargeable batteries and are packaged in weatherproof enclosures. The master unit and each of the slave units are equipped with a time-modulated ultra-wide-band (TMUWB) radio transceiver, which spreads its RF energy over several gigahertz by transmitting extremely low-power and super-narrow pulses. In this prototype system, each slave node can be connected to as many as six sensors: two sensors can be connected directly to analog-to-digital converters (ADCs) in the slave node and four sensors can be connected indirectly to the ADCs via signal conditioners. The maximum sampling rate for streaming data from any given sensor is about 5 kHz. The bandwidth of one channel of the TM-UWB radio communication system is sufficient to accommodate streaming of data from five slave nodes when they are fully loaded with data collected through all possible sensor connections. TM-UWB radios have a much higher spatial capacity than traditional sinusoidal wave-based radios. Hence, this TM-UWB wireless data-acquisition can be scaled to cover denser sensor setups for rocket engine test stands. Another advantage of TM-UWB radios is that it will not interfere with existing wireless transmission. The maximum radio-communication range between the master node and a slave node for this prototype system is about 50 ft (15 m) when the master and slave transceivers are equipped with small dipole antennas. The range can be increased by changing to

    The Cathode Strip Chamber (CSC) [1] Data Acquisition (DAQ) system for the CMS [2] experiment at the LHC [3] will be described. The CSC system is large, consisting of 218K cathode channels and 183K anode channels. This leads to a substantial data rate of ~1.5GByte/s at LHC design luminosity (1034cm-2s-1) and the CMS first level trigger (L1A) rate of 100KHz. The DAQ system consists of three parts. The first part is on-chamber Cathode Front End Boards (CFEB)[4], which amplify, shape, store, and digitise chamber cathode signals, and Anode Front End Boards (AFEB)[5], which amplify, shape and discriminate chamber anode signals. The second part is the Peripheral Crate Data Acquisition Motherboards (DAQMB), which control the onchamber electronics and the readout of the chamber. The third part is the off-detector DAQ interface boards, which perform real time error checking, electronics reset requests and data concentration. It passes the resulting data to a CSC local DAQ farm, as well as CMS main DAQ [6]. All electron...

    In order to observe overburden media changes caused by mining processing, we take the fully-mechanized working face of the BLT coal mine in Shendong mine district as an example to develop a 4D seismic data acquisition methodology during coal mining. The 4D seismic data acquisition is implemented to collect 3D seismic data four times in different periods, such as before mining, during the mining process and after mining to observe the changes of the overburden layer during coal mining. The seismic data in the research area demonstrates that seismic waves are stronger in energy, higher in frequency and have better continuous reflectors before coal mining. However, all this is reversed after coal mining because the overburden layer has been mined, the seismic energy and frequency decrease, and reflections have more discontinuities. Comparing the records collected in the survey with those from newly mined areas and other records acquired in the same survey with the same geometry and with a long time for settling after mining, it clearly shows that the seismic reflections have stronger amplitudes and are more continuous because the media have recovered by overburden layer compaction after a long time of settling after mining. By 4D seismic acquisition, the original background investigation of the coal layers can be derived from the first records, then the layer structure changes can be monitored through the records of mining action and compaction action after mining. This method has laid the foundation for further research into the variation principles of the overburden layer under modern coal-mining conditions. (paper)

  18. Computerized system of data acquisition, primary processing and data storage

    The present system was proposed in order to collect and conveniently document data alphanumeric. The application of this system in the nuclear area was motivated by the demand originated by the enviromental monitoring program in nuclear installations. This is possible due to the flexibility offered by the system, which can have a general purpose utilization, with exception of the normalization circuits. In the nuclear area the collected data will be basically meteorological, of use in the development of atmospheric diffusion models. The data will be useful to estimate the radiation doses to the public, resultant of accidental or routine liberation of radioactive material to the atmosphere. The evolution of the potential dose received by the public, resulting from a hypothetic reactor accident, could be calculated from these data, as well. The system, from the electronic point of view, utilizes scale large integration technology, being constitued basically by the following functional blocks: -Transducer, -Normalization circuits, -Analog multiplexer, -Analog digital converter, -Microprocessor, -Interface to cassette records, -Interface to cassette read, -Cassette.

  1. Software upgradation of PXI based data acquisition for Aditya experiments

    Aditya Data Acquisition and Control System is designed to acquire data from diagnostics like Loop Voltage, Rogowski, Magnetic probes, X-rays etc and for control of gas feed, gate valve control, trigger pulse generation etc. CAMAC based data acquisition system was updated with PXI based Multifunction modules. The System is interfaced using optical connectivity with PC using PCI based controller module. Data is acquired using LabVIEW graphical user interface (GUI) and stored in server. The present GUI based application does not have features like module parameters configuration, analysis, webcasting etc. So a new application software using LabVIEW is being developed with features for individual module support considering programmable channel configuration - sampling rate, number of pre and post trigger samples, number of active channel selection etc. It would also have facility of using multi-functionality of timer and counter. The software would be scalable considering more modules, channels and crates along with security of different access level of user privileges. (author)

    Colombo, Tommaso; The ATLAS collaboration; Vandelli, Wainer

    2015-01-01

    The ATLAS detector at CERN records particle collision “events” delivered by the Large Hadron Collider. Its data-acquisition system is a distributed software system that identifies, selects, and stores interesting events in near real-time, with an aggregate throughput of several 10 GB/s. It is a distributed software system executed on a farm of roughly 2000 commodity worker nodes communicating via TCP/IP on an Ethernet network. Event data fragments are received from the many detector readout channels and are buffered, collected together, analyzed and either stored permanently or discarded. This system, and data-acquisition systems in general, are sensitive to the latency of the data transfer from the readout buffers to the worker nodes. Challenges affecting this transfer include the many-to-one communication pattern and the inherently bursty nature of the traffic. In this paper we introduce the main performance issues brought about by this workload, focusing in particular on the so-called TCP incast pathol...

  4. Flexible data acquisition system for experiments at COSY

    For the KFA Juelich COoler SYnchrotron (COSY) a general data acquisition system was developed. Its architecture is based on available standards (VME, FASTBUS, CAMAC, VICbus) and UNIX Workstations forming a distributed processor system. Based on this hardware a flexible and modular data acquisition software was designed allowing the configuration of various experiment arrangements. The software design for run control is arranged according to a client server connectivity model as well as to an object oriented structure. It is logically based on MAP/MMS (ISO9506), a powerful application layer protocol for distributed automation systems in industry. In this application servers are implemented on the mProcessor controller boards at the front end. On the workstation side the experiment control client consists of dedicated processes with access to the configurable experiment data base. The user interface is realized by OSF/Motif. Established software standards for online data analysis high energy physics are employed. The authors discuss the most important design decisions mainly focusing on the software aspects

  5. A PET camera simulator with multispectral data acquisition capabilities

    The Sherbrooke PET simulator was designed and built to investigate parameters which influence the performance of a high resolution PET camera based on avalanche photodiode detectors. The simulator consists of a computer controlled scanning table with 32 detection channels shared between front-end cassettes and FASTBUS boards, and of a PC-based multichannel analyzer (MCA) used as an histogramming memory for multi-parametric data acquisition. Tomographic data are collected by scanning one of two opposite arrays of detectors and by rotating the object in a predetermined sequence to simulate a complete ring of detectors with various sampling schemes. All acquisition parameters, such as detector bias, discriminator noise thresholds, timing delays, energy and coincidence time windows, are programmable through digital-to-analog converters or on-board registers. Data can be acquired in several modes: calibration, where direct or coincident energy spectra from all detectors can be registered simultaneously; standard, where only energy-validated coincident events are histogrammed as lines-of-response (LORs) addresses; and multispectral, where the LOR address is encoded with the energy information to provide a multi-parameter histogram. Data samples obtained in these modes are presented

  6. FASTBUS Readout Controller card for high speed data acquisition

    This article describes a FASTBUS Readout Controller (FRC) for high speed data acquisition in FASTBUS based systems. The controller has two main interfaces: to FASTBUS and to a Readout Port. The FASTBUS interface performs FASTBUS master and slave operations at a maximum transfer rate exceeding 40 MBytes/s. The Readout Port can be adapted for a variety of protocols. Currently, it will be interfaced to a VME bus based processor with a VSB port. The on-board LR33000 embedded processor controls the readout, executing a list of operations download into its memory. It scans the FASTBUS modules and stores the data in a triple port DRAM (TPDRAM), through one of the Serial Access Memory (SAM) ports of the (TPDRAM). Later, it transfers this data to the readout port using the other SAM. The FRC also supports serial communication via RS232 and Ethernet interfaces. This device is intended for use in the data acquisition system at the Collider Detector at Fermilab. 5 refs., 3 figs

  8. Multiple, multi-dimensional data acquisition and analysis system SHINE

    The data acquisition system in the Tandem Accelerator Center, University of Tsukuba, has been built through two large steps of development. The first step development was started in 1976 when the construction of the tandem accelerator was completed, and completed in 1977, preparing 16 bit small computer of PDP11/40-PDP11/50 and 16 NIM type AD converters by CAMAC interface as data front. This system was named ''SHINE'', and has been utilized as a common utilization facility. For the purpose of increasing the capacity of data acquisition and analysis and improving the function of the whole system, the second step development centering around VAX11/750-VAX11/780 32 bit computer was begun in 1984, and took the place of the PDP system in 1986. In the new SHINE system, the easiness of use and the improvement of function were promoted. In this book, the outline of SHINE, the constitution of the system, the method of using the system, program control, the guide for data file processing, SHINE standard CAMAC module, HISS routine, and real time display process are described.

  9. Data acquisition, remote control and equipment monitoring for ISOLDE RILIS

    Highlights: • The requirements for continuous and automated RILIS operation are outlined. • Laser wavelength, power, beam position and pulse timing are continuously monitored. • A network-extended LabVIEW-based equipment operation framework was developed. • The system serves as a foundation for collaborative laser spectroscopy data acquisition. • Example applications have been successfully tested with ISOLDE experiment setups. -- Abstract: With a steadily increasing on-line operation time up to a record 3000 h in the year 2012, the Resonance Ionization Laser Ion Source (RILIS) is one of the key components of the ISOLDE on-line isotope user facility at CERN. Ion beam production using the RILIS is essential for many experiments due to the unmatched combination of ionization efficiency and selectivity. To meet the reliability requirements the RILIS is currently operated in shift duty for continuous maintenance of crucial laser parameters such as wavelength, power, beam position and timing, as well as ensuring swift intervention in case of an equipment malfunction. A recent overhaul of the RILIS included the installation of new pump lasers, commercial dye lasers and a complementary, fully solid-state titanium:sapphire laser system. The framework of the upgrade also required the setup of a network-extended, LabVIEW-based system for data acquisition, remote control and equipment monitoring, to support RILIS operators as well as ISOLDE users. The system contributes to four key aspects of RILIS operation: equipment monitoring, machine protection, automated self-reliance, and collaborative data acquisition. The overall concept, technologies used, implementation status and recent applications during the 2012 on-line operation period will be presented along with a summary of future developments

The EMS framework is based on component technology, graphical assembly of systems, introspection and flexibility to accommodate various data processing and data acquisition components. Core system components, common to many application domains, have been identified and designed together with the domain-specific components for the measurement of accelerator magnets. The EMS employs several modern technologies and the result is a highly portable, configurable, and potentially distributed system, with the capability of parallel signal data processing, parameterized test scripting, and run-time reconfiguration

  11. The data acquisition system for BNL AGS experiment 791

    A high-rate data acquisition system has been developed and used to take physics data for Brookhaven AGS Experiment 791, a search for a rare kaon decays. The system achieves high throughput by using multilevel triggering, 'flash' digitizing, and a highly parallel pipelined readout architecture. Commercial ECL logic is used for the first level trigger, custom-built modules for the second level trigger, and 3081/E processors for the third level trigger. The 'flash' front end electronics digitize signals within 200 nsec of their arrival, and these electronics are implemented in a custom-protocol parallel pipelined readout architecture. This parallel readout of data from the front end to dual-port memory in the 3081/E's is done through a 24 byte wide bus and achieves a transfer rate of 200 Mbyte/sec. A host Micro-VAX handles the transfer of the filtered data from the 3081/E's to magnetic tape

  12. Data acquisition for a medical imaging MWPC detector

    Multiwire proportional chambers, combined with drilled Pb converter stacks, are used as position sensitive gamma-ray detectors for medical imaging at Queen's University. This paper describes novel features of the address readout and data acquisition system. To obtain the interaction position, induced charges from wires in each cathode plane are combined using a three-level encoding scheme into 16 channels for amplification and discrimination, and then decoded within 150 ns using a lookup table in a 64 Kbyte EPROM. A custom interface card in an AT-class personal computer provides handshaking, rate buffering, and diagnostic capabilities for the detector data. Real-time software controls the data transfer and provides extensive monitor and control functions. The data are then transferred through an Ethernet link to a workstation for subsequent image analysis. (orig.)

    The data acquisition hardware and software for a large deep underground nucleon stability detector is described. Such hardware must process the information from an array of greater than 2000 photomultiplier tubes in real time, in the presence of a cosmic-ray background of about three events per second. A hierarchical scheme of processors and memory is used to perform real time pattern recognition and event identification with negligible impact on dead time. Fast, but crude, algorithms have been developed to reduce the offline analysis work load without endangering any of the alternative physics objectives, such as neutrino oscillations or neutrino burst detection.

The system uses the CAN industrial data transmission network and the DeviceNet high-level protocol. The hardware part is the set of controllers, which convert signals of the detecting devices into a frequency and transmit them in the digital form via the CAN network to the host computer. The software realizes the DeviceNet protocol stack, which ensures the data acquisition and transmission. The user interface is based on dynamic WEB pages. The system is used for monitoring dark noises of photomultiplier tubes in the BOREXINO neutrino detector (Italy)

  13. Laser velocimeter data acquisition, processing, and control system

    The use of a mini-computer for data acquisition, processing, and control of a two-velocity-component dual beam laser velocimeter in a low-speed wind tunnel is described in detail. Digital stepping motors were programmed to map the mean-flow and turbulent fluctuating velocities in the test section boundary layer and free stream. The mini-computer interface controlled the operation of the LV processor and the high-speed selection of the photomultiplier tube whose output was to be processed. A statistical analysis of the large amount of data from the LV processor was performed by the computer while the experiment was in progress. The resulting velocities are in good agreement with hot-wire survey data obtained in the same facility

    Zhang Chi; Yu Xiaoqi; Yang Tao

    2005-01-01

    A Data Acquisition System (DAQ) for electron energy loss coincident spectrometers (EELCS) has been developed. The system is composed of a Multiplex Time-Digital Converter (TDC) that measures the flying time of positive and negative ions and a one-dimension positionsensitive detector that records the energy loss of scattering electrons. The experimental data are buffered in a first-in-first-out(FIFO) memory module, then transferred from the FIFO memory to PC by the USB interface. The DAQ system can record the flying time of several ions in one collision, and allows of different data collection modes. The system has been demonstrated at the Electron Energy Loss Coincident Spectrometers at the Laboratory of Atomic and Molecular Physics, USTC. A detail description of the whole system is given and experimental results shown.

  15. A DSP based data acquisition module for colliding beam accelerators

    In 1999, the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory will accelerate and store two beams of gold ions. The ions will then collide head on at a total energy of nearly 40 trillion electron volts. Attaining these conditions necessitates real-time monitoring of beam parameters and for this purpose a flexible data acquisition platform has been developed. By incorporating a floating point digital signal processor (DSP) and standard input/output modules, this system can acquire and process data from a variety of beam diagnostic devices. The DSP performs real time corrections, filtering, and data buffering to greatly reduce control system computation and bandwidth requirements. We will describe the existing hardware and software while emphasizing the compromises required to achieve a flexible yet cost effective system. Applications in several instrumentation systems currently construction will also be presented

  16. Microprocessor event analysis in parallel with Camac data acquisition

    The Plessey MIPROC-16 microprocessor (16 bits, 250 ns execution time) has been connected to a Camac System (GEC-ELLIOTT System Crate) and shares the Camac access with a Nord-1OS computer. Interfaces have been designed and tested for execution of Camac cycles, communication with the Nord-1OS computer and DMA-transfer from Camac to the MIPROC-16 memory. The system is used in the JADE data-acquisition-system at PETRA where it receives the data from the detector in parallel with the Nord-1OS computer via DMA through the indirect-data-channel mode. The microprocessor performs an on-line analysis of events and the result of various checks is appended to the event. In case of spurious triggers or clear beam gas events, the Nord-1OS buffer will be reset and the event omitted from further processing. (orig.)

  17. A 256 channel digital filter for a data acquisition system

    The TRIUMF Central Control System (CCS) employs several data acquisition systems to monitor its operational parameters. Each system multiplexes 256 analog channels into one analog to digital converter. Space constraints on the multiplexer cards prohibit the installation of adequate anti-alias filters which allows 60 Hz and other noise to corrupt the measurements. The new system overcomes this problem by sampling each channel at a 160 samples/second rate and using a DSP microcomputer to lowpass filter the data. The multiplexer and analog-digital converter operate at 256 times the channel sample rate. The channel filter bandwidth is restricted to approximately 1 Hz due to the rate at which the CCS reads the data. One DSP microcomputer is able to filter the 256 channels in a multiplexed system at a cost less than that of the anti-alias filters which would otherwise have been required

  18. Data acquisition system for isochronous mass measurement at CSRe

    Isochronous mass measurement is one of physics research projects at CSRe of HIRFL-CSR. The signals induced by circulating ions are amplified and sampled with a digital oscilloscope Tektronix DPO 71254 at a sampling rate of 50 GSa/s. The record length of one injection is 200 μS. A program based on LabView and TekVISA is developed to automatically save the sampled data and display the time domain waveform. The pro- gram is also designed to on -line analyze the data to get the power spectrum of circulating ions. Principle of isochronous mass measurement at CSRe and the data acquisition system are introduced, and the application results are reported. (authors)

  19. Atlas Data Acquisition: from Run I to Run II

    Panduro Vazquez, J G; The ATLAS collaboration

    2014-01-01

    The experience gained during the first period of very successful data taking of the ATLAS experiment (Run I) has inspired a number of ideas for improvement of the Data AcQuisition (DAQ) system that are being put in place during the so-called Long Shutdown 1 of the Large Hadron Collider (LHC), in 2013/14. We have updated the data-flow architecture, rewritten an important fraction of the software and replaced hardware, profiting from state of the art technologies. This paper summarizes the main changes that have been applied to the ATLAS DAQ system and highlights the expected performance and functional improvements that will be available for the LHC Run II. Particular emphasis will be put on explaining the reasons for our architectural and technical choices, as well as on the simulation and testing approach used to validate this system.

  20. A DSP controlled data acquisition system for CELSIUS

    Bengtsson, M; Ziemann, Volker

    2000-01-01

    We describe a data acquisition system based on two 10 MHz A/D-converters, a SHARC Digital Signal Processor (DSP), and a digital synthesizer used for triggering the A/D-converters. The temporal macrostructure of the data acquisition can be determined by external triggers or by timer interrupts from the DSP. In this way up to two million samples can be stored in DSP external memory. The samples are analyzed by directly fast Fourier transforming blocks of samples. In another mode we use software-based downmixing and filtering techniques to increase the resolution and zoom in on a small frequency band. Spectra of up to 5 MHz can be manipulated and displayed as waterfall plots or spectral maps on the host computer directly. Moreover, signals of up to 70 MHz can be analyzed by undersampling techniques. We use this system to analyze Schottky spectra from electron-cooled ion beams in CELSIUS and report drag rate measurements and observations of instabilities.

  1. Design of the APS RF BPM Data Acquisition Upgrade

    Lill, Robert M; Norum, Eric; Pietryla, Anthony

    2005-01-01

    The Advanced Photon Source (APS) is a third-generation synchrotron light source in its tenth year of operation. The storage ring employs three different types of beam position monitor (BPM) systems to measure and control beam motion. The monopulse radio frequency (rf) BPM is a broadband (10 MHz) system, which is considered to be the backbone of orbit control. The rf BPM system was designed to measure single-turn and multi-turn beam positions. The rf BPMs are presently suffering from an aging data acquisition system. By replacing only the data acquisition we will revitalize this system for another decade and demonstrate a cost-effective approach to improved beam stability, reliability, and enhanced postmortem capabilities. In this paper we present the design of an eight-channel ADC/digitizer VXI board with a sampling rate of 88 MHz (per channel) and 14-bit resolution coupled with a field-programmable gate array and embedded central processing. We will discuss the upgrade system specifications, design, and prot...

  2. Design of a Data Acquisition System for a Flying Laboratory

    2000-01-01

    Full Text Available The University of Glasgow, Department of Aerospace Engineering has been in possession of a Czech manufactured Remotely Piloted Vehicle (RPV airframe 1 since 1996. Significant modifications have been made and will continue to be made in order to render the design functional and airworthy. The name ‘Condor’ was chosen as the moniker for the new aircraft. The latest phase of these modifications is the design and implementation of the Condor’s in-flight data acquisition (DAQ system. The paper will outline the various processes involved and decisions made in the design and implementation of a simple data acquisition system for a RPV. The requirements of the system were first identified, such as those quantities that were deemed essential to the effective operation of the RPV. For example, airspeed, angle of attack, angle of sideslip etc. and the necessary instrumentation for measuring such values chosen and the subsequent signal conditioning needed for the signals to be intelligible to the DAQ Card and computer.

  3. Toward the First Data Acquisition Standard in Synthetic Biology.

    Sainz de Murieta, Iñaki; Bultelle, Matthieu; Kitney, Richard I

    2016-08-19

    This paper describes the development of a new data acquisition standard for synthetic biology. This comprises the creation of a methodology that is designed to capture all the data, metadata, and protocol information associated with biopart characterization experiments. The new standard, called DICOM-SB, is based on the highly successful Digital Imaging and Communications in Medicine (DICOM) standard in medicine. A data model is described which has been specifically developed for synthetic biology. The model is a modular, extensible data model for the experimental process, which can optimize data storage for large amounts of data. DICOM-SB also includes services orientated toward the automatic exchange of data and information between modalities and repositories. DICOM-SB has been developed in the context of systematic design in synthetic biology, which is based on the engineering principles of modularity, standardization, and characterization. The systematic design approach utilizes the design, build, test, and learn design cycle paradigm. DICOM-SB has been designed to be compatible with and complementary to other standards in synthetic biology, including SBOL. In this regard, the software provides effective interoperability. The new standard has been tested by experiments and data exchange between Nanyang Technological University in Singapore and Imperial College London. PMID:26854090

  4. Supercritical water oxidation data acquisition testing. Final report, Volume II

    Supercritical Water Oxidation (SCWO) technology holds great promise for treating mixed wastes, in an environmentally safe and efficient manner. In the spring of 1994 the US Department of Energy (DOE), Idaho Operations Office awarded Stone ampersand Webster Engineering Corporation, of Boston Massachusetts and its sub-contractor MODAR, Inc. of Natick Massachusetts a Supercritical Water Oxidation Data Acquisition Testing (SCWODAT) program. The SCWODAT program was contracted through a Cooperative Agreement that was co-funded by the US Department of Energy and the Strategic Environmental Research and Development Program. The SCWODAT testing scope outlined by the DOE in the original Cooperative Agreement and amendments thereto was initiated in June 1994 and successfully completed in December 1995. The SCWODAT program provided further information and operational data on the effectiveness of treating both simulated mixed waste and typical Navy hazardous waste using the MODAR SCWO technology

  5. Computer simulation of low-frequency electromagnetic data acquisition

    SanFilipo, W.A.; Hohmann, G.W.

    1982-02-01

    Computer simulation of low frequency electromagnetic (LFEM) digital data acquisition in the presence of natural field noise demonstrates several important limitations and considerations. Without the use of a remote reference noise removal scheme it is difficult to obtain an adequate ratio of signal to noise below 0.1 Hz for frequency domain processing and below 0.3 Hz base frequency for time domain processing for a typical source-receiver configuration. A digital high-pass filter substantially facilitates rejection of natural field noise above these frequencies but, at lower frequencies where much longer stacking times are required, it becomes ineffective. Use of a remote reference to subtract natural field noise extends these low-frequency limits a decade, but this technique is limited by the resolution and dynamic range of the instrumentation. Gathering data in short segments so that natural field drift can be offset for each segment allows a higher gain setting to minimize dynamic range problems.

  6. Trigger and data acquisition: The bytes start and stop here!

    The modern trigger and data acquisition systems that instrument discovery experiments at the Large Hadron Collider (LHC) at CERN are very complex digital systems that select, reduce, and process enormous volumes of data in real-time to match the resources of state-of-the-art distributed computing available to researchers. Never before in particle physics have such powerful digital reconstruction and filtering systems been matched to a world-wide distributed system of computing of unprecedented scale. The goal of these massive aggregate computing systems is to extract as much physical information as possible from collision events at the LHC with well understood selection criteria and biases. Current strategies and future challenges in providing these aggregate real-time and offline computing systems are described.

    2010-01-01

    The CMS Data Acquisition cluster, which runs around 10000 applications, is configured dynamically at run time. XML configuration documents determine what applications are executed on each node and over what networks these applications communicate. Through this mechanism the DAQ System may be adapted to the required performance, partitioned in order to perform (test-) runs in parallel, or re-structured in case of hardware faults. This paper presents the CMS DAQ Configurator tool, which is used to generate comprehensive configurations of the CMS DAQ system based on a high-level description given by the user. Using a database of configuration templates and a database containing a detailed model of hardware modules, data and control links, nodes and the network topology, the tool automatically determines which applications are needed, on which nodes they should run, and over which networks the event traffic will flow. The tool computes application parameters and generates the XML configuration documents as well a...

  8. Design of an MRI quadrature-data acquisition card

    2006-01-01

    A design of a quadrature-data acquisition card based on peripheral component interconnect (PCI) bus for mini-type magnetic resonance imaging (MRI) system is reported. It uses two high speed analog-to-digital converters (ADCs) to sample the MRI signals and two static random access memories (SRAMs) to store the data which will be read to the computer by PCI bus after sampling. All the logic control signals on the card are generated by the field programmable gate array (FPGA). The software Foundation3.1 is used to design the FPGA and achieve useful result after simulating and implementing. The card has some merits that normal commercial cards do not have. For example, the sampling parameters can be varied according to different pulse sequences.

  9. Global detector network: data acquisition on the LHC

    The Global Detector Network group is preparing recommendations for future high energy physics experiments to allow to operate detectors from different laboratories around the world. The GDN investigates technical, security, and social aspects involved in remote operation of HEP experiment. The group currently focuses on gaining experience from recent experiments. The ATLAS is one of 2 main experiments on the LHC, and its Data Acquisition System deals with the enormous task to reduce the approximate initial data flow of 1 PB/s to storage suitable value of 300 MB/s. This is achieved by 3 levels of rejection, each of them dealing with tough time constraints and requested rejection factor. Both specially designed hardware components and commercial PCs are used for this task. The safety and environmental issues are addressed, at the ATLAS experiment, by the separate Detector Control System. (author)

  10. Experiences at HERA with the H1 data acquisition system

    The recently commissioned HERA collider provides a significant pointer to the problems that have to be surmounted in data acquisition systems at the next generation of hadron machines. With bunch crossings, between 30 GeV electrons and 820 GeV protons, 96 nanoseconds apart, the H1 experiment illustrates the application of sophisticated pipelining solutions in the readout of several hundred thousand electronic channels. A modular, multiprocessor design structure emphasis the architectural concepts necessary to cope with large data throughput and yet remain flexible enough to exploit ongoing technological advances in both hardware and software. The range of techniques implemented will be surveyed, covering various digitisation solutions at the front-end through to embedded microprocessor arrays in standard busses controlled by graphics-based stations executing object- orientated code. The experiences gained in developing such a system are also discussed. (orig.)

    2011-01-01

    Though constantly evolving and improving, the available network monitoring solutions have limitations when applied to the infrastructure of a high speed real-time data acquisition (DAQ) system. DAQ networks are particular computer networks where experts have to pay attention to both individual subsections as well as system wide traffic flows while monitoring the network. The ATLAS Network at the Large Hadron Collider (LHC) has more than 200 switches interconnecting 3500 hosts and totaling 8500 high speed links. The use of heterogeneous tools for monitoring various infrastructure parameters, in order to assure optimal DAQ system performance, proved to be a tedious and time consuming task for experts. To alleviate this problem we used our networking and DAQ expertise to build a flexible and scalable monitoring system providing an intuitive user interface with the same look and feel irrespective of the data provider that is used. Our system uses custom developed components for critical performance monitoring and...

  12. Development and Integration of a Data Acquisition System for SST-1 Phase-1 Plasma Diagnostics

    Long pulse (of the order of 1000 s or more) SST-1 tokamak experiments demand a data acquisition system that is capable of acquiring data from various diagnostics channels without losing useful data (and hence physics information) while avoiding unnecessary generation of a large volume data. SST-1 Phase-1 tokamak operation has been envisaged with data acquisition of several essential diagnostics channels. These channels demand data acquisition at a sampling rate ranging from 1 kilo samples per second (KSPS) to 1 mega samples per second (MSPS). Considering the technical characteristics and requirements of the diagnostics, a data acquisition system based on PXI and CAMAC has been developed for SST-1 plasma diagnostics. Both these data acquisition systems are scalable. Present data acquisition needs involving slow plasma diagnostics are catered by the PXI based data acquisition system. On the other hand, CAMAC data acquisition hardware meets all requirements of the SST-1 Phase-1 fast plasma diagnostics channels. A graphical user interface for both data acquisition systems (PXI and CAMAC) has been developed using LabVIEW application development software. The collected data on the local hard disk are directly streaming to the central server through a dedicated network for post-shot data analysis. This paper describes the development and integration of the data acquisition system for SST-1 Phase-1 plasma diagnostics. The integrated testing of the developed data acquisition system has been performed using SST-1 central control and diagnostics signal conditioning units. In the absence of plasma shots, the integrated testing of the data acquisition system for the initial diagnostics of SST-1 Phase-1 operation has been performed with simulated physical signals. The primary engineering objective of this integrated testing is to validate the performance of the developed data acquisition system under simulated conditions close to that of actual tokamak operation.

    1986-01-01

    An overview is given of the data acquisition, signal processing, and data analysis techniques that are currently in use with high power MST/ST (mesosphere stratosphere troposphere/stratosphere troposphere) radars. This review supplements the works of Rastogi (1983) and Farley (1984) presented at previous MAP workshops. A general description is given of data acquisition and signal processing operations and they are characterized on the basis of their disparate time scales. Then signal coding, a brief description of frequently used codes, and their limitations are discussed, and finally, several aspects of statistical data processing such as signal statistics, power spectrum and autocovariance analysis, outlier removal techniques are discussed.

  16. Large-bandwidth data acquisition network for XFEL facility, SACLA

    The SACLA (SPring-8 Angstrom Compact Free Electron Laser) facility consists of an accelerator building, an undulator building and an experimental facility. SACLA is designed to produce X-ray with a wavelength as short as 0.06 nm and with a repetition rate of 60 Hz. X-ray Free-Electron Laser (XFEL) experiments demands large bandwidth network for data acquisition (DAQ). At SACLA the experimental data rate is to be up to 5.8 Giga bit per second (Gbps). Some of the experiments demands preprocessing and on-line analysis by high-performance computers. In order to fulfill these requirements, a dedicated network system for DAQ and data analysis has been developed. A DAQ network consists of a dedicated 10 Gbps Ethernet (10 GbE) physical layer to secure the data bandwidth and a 1 GbE layer for instrument controls. The DAQ network is connected to a primary storage and indirectly to a PC cluster for data preprocessing. A fire-wall system with virtual private network (VPN) features is also implemented in order to secure remote access from off-site institutes. The use of a large-bandwidth data transfer technique allows the efficient transfer of pre-processed data from SACLA to an off-site supercomputer

  17. Data acquisition system realization for H1 experiment

    The acquisition and trigger system for H1 liquid argon calorimeter deals with severe constraints which have to be taken into account. We describe the system which results from these constraints, emphasizing the solutions adopted to meet the specificities of the detector and the difficult experimental conditions at HERA: high physical background (104-5 Hz), physics and background events pile up (10%), large crossing frequency of proton and electron bunches (10.4 MHz). Next, we present a detailed description of the acquisition and online control scheme used during the calorimetry tests in SPS beam, at CERN. This test system, prefiguring the final one (which will start to work at the end of 1989), includes a fast frontal processor CAB (taking charge of the electronics read out and sequencing, and furthermore producing simple histograms). The CAB is controlled by a Micro Vax computer which realizes the user interface, allowing a quick visualisation and verification of the acquired data, these functions being performed in multitasking environment

  18. Evolution of the ATLAS Trigger and Data Acquisition System

    Pozo Astigarraga, M E; The ATLAS collaboration

    2014-01-01

    ATLAS is a Physics experiment that explores high-energy particle collisions at the Large Hadron Collider at CERN. It uses tens of millions of electronics channels to capture the outcome of the particle bunches crossing each other every 25 ns. Since reading out and storing the complete information is not feasible (~100 TB/s), ATLAS makes use of a complex and highly distributed Trigger and Data Acquisition (TDAQ) system, in charge of selecting only interesting data and transporting those to permanent mass storage (~1 GB/s) for later analysis. The data reduction is carried out in two stages: first, custom electronics performs an initial level of data rejection for each bunch crossing based on partial and localized information. Only data corresponding to collisions passing this stage of selection will be actually read-out from the on-detector electronics. Then, a large computer farm (~17 k cores) analyses these data in real-time and decides which ones are worth being stored for Physics analysis. A large network a...

  20. Prototype VME data acquisition card for the ZEUS calorimeter

    This paper discusses the design of a prototype data acquisition (DAQ) card for the ZEUS calorimeter. The card accepts two multiplexes analog data streams at a 1 MHz rate, and digitizes and stores the data for subsequent transfer through VME to a host computer. The data is buffered by a high-speed asynchronous FIFO following the A/D converters, and written into Data Memory on the card, either directly or after processing by an on-board digital signal processor (DSP). Each card has a 16-bit control-status register (CSR), the bits of which configure the hardware and define the hardware options. The 1/4 Mbyte of high speed CMOS static RAM appears either as a FIFO, or mapped memory depending upon a bit in the CSR. The card is designed to make use of the 32-bit data and address buses supported by VME, and accordingly can be most efficiently utilized in conjunction with a processor in the VME environment such as the 68020, which supports longword transfers in a 32-bit address space. The card is constructed on a ten layer printed circuit, with almost all components being surface-mount devices. All logic is implemented in PLD's. 5 refs., 4 figs., 3 tabs

  2. S3DACS - SPACE SIMULATOR SYSTEM DATA ACQUISITION AND CONTROL

    De, Freitas Bart F.

    1994-01-01

    The S3 Data Acquisition and Control System, S3DACS, was developed for the Environmental Test Laboratory and Space Simulator at NASA's Jet Propulsion Laboratory. The program is used for monitoring, controlling, and recording information acquired during tests and presenting this information in various formats for easy access by a large number of users. All testing is initiated by a setup procedure that defines what will be tested, limits to be checked, formulas to use, etc. Test results (e.g. temperature, resistance) are then automatically stored in a database for real time display and for future reference.

  3. The Wireless Data Acquisition System for the Vibration Table

    Teng, Y. T.; Hu, X.

    2014-12-01

    The vibration table is a large-scaled tool used for inspecting the performance of seismometers. The output from a seismometer on the table can be directly monitored when the vibration table moves in certain pattern. Compared with other inspection methods, inspecting seismometers' performance indicators (frequency response, degree of linearity, sensitivity, lateral inhibition and dynamic range etc). using vibration tables is more intuitive. Therefore, the vibration tables are an essential testing part in developing new seismometers and seismometer quality control. Whereas, in practice, a cable is needed to connect the seismometer to the ground equipments for its signal outputs and power supply, that means adding a time-varying nonlinear spring between the vibration table and ground. The cable adds nonlinear feature to the table, distorts the table-board movement and bring extra errors to the inspecting work and affected the testing accuracy and precision. In face of this problem, we developed a wireless acquiring system for the vibration table. The system is consisted of a three-channel analog-to-digital conversion, an acquisition control part, local data storage, network interface, wireless router and power management, etc. The analog-to-digital conversion part uses a 24-digit high-precision converter, which has a programmable amplifier at the front end of its artificial circuit, with the function of matching outputs with different amplifier from the vibration table. The acquisition control part uses a 32 bit ARM processor, with low-power dissipation, minute extension and high performance. The application software platform is written in Linux to make the system convenient for multitasking work. Large volume local digital storage is achieved by a 32G SD card, which is used for saving real time acquired data. Data transmission is achieved by network interface and wireless router, which can simplify the application software by the supported TCP/IP protocol. Besides

    1995-12-31

    Packages designed to transport radioactive materials are required to survive exposure to environments defined in Code of Federal Regulations. Cask designers can investigate package designs through structural and thermal testing of full-scale packages, components, or representative models. The acquisition of reliable response data from instrumentation measurement devices is an essential part of this testing activity. Sandia National Laboratories, under the sponsorship of the US Department of Energy (DOE), has developed the Mobile Instrumentation Data Acquisition System (MIDAS) dedicated to the collection and processing of structural and thermal data from regulatory tests.

    2005-01-01

    This paper introduced recent development of data acquisition system(DAS) on the HL-2A tokamak. The existing DAS has to be remodeled because of the evident improvement on HL-2A itself and the increasing amount of corresponding experimental data. First, the experimental network on HL-2A Tokamak as a communication center is described in detail. Secondly,"The File's Format & Criterion of Experimental Data on HL-2A Tokamak" as the core of the new software is also presented. Thirdly, not only a multi-screen image display system on HL-2A is discussed, but also the build-up of a new display wall system is dealt with. Finally, on the graphical WINDOWS platform and on the basis of the new Data File's Format & Criterion, the new software on HL-2A is described, including a new multi-layer database management program,a real-time processing program, a common interactive analytic processing program and a data post-processing program, which is now under development.

  6. Data acquisition system based on the 15 VSM-5 microcomputer

    Data acquisition system based on the programmable 15 vsm-5 microcomputer is described. Data are accepted from transducers and recorded on a magnetic tape for subsequent processing on the BESM-6 computer. The system comprises transducers, signal commutator, analog-to-digital converter (ADC), magnetic tape recorder ''Majak-203'', the ''CONSUL-260'' printer and is controlled by specially developed microprograms placed in a 15 VCM-5, permanent memory device. Magnetic tape recording reading unit and interface are developed through which microprograms control the whole system. Besides transducer data, two control numbers corresponding to ''zero'' and middle of the range of accepted from the ADC numbers are recorded on the magnetic tape. An means of control numbers the ADC reading drift is determined and corrected at processing. For ensuring data reliability the recorded data are controlled. The minimum inquiry period is 5 ms for each transducer. The magnetic tape can be used for recording dode digit binary or hexadigit binary-decimal codes. The measuring accuracy is determined by ADC accuracy and equals 0.2%

    The new data acquisition system of large helical device (LHD) diagnostics, i.e. LABCOM system, has successfully started its operation in March 1998. It has a simple but massive parallel-processing (MPP) structure by means of multiple PC/Windows NT environment, and the most significant methodology adopted for it is the object-oriented (OO) data handling through the whole system. The functions and data substances of the acquisition system are described in autonomous objects with the corresponding C++ class definitions. The object-oriented database management system (ODBMS) will be the only solution to provide a vast and virtual storage space for storing an enormous number of archiving data objects. Commercial ODBMS product 'O2' are installed on each diagnostic acquisition computer. Practical O2 investigations showed 300-400 kB/s as the data storing rate, whereas the data transfer rate from CAMAC digitizers to the computer is up to 700 kB/s in this system. Applying the GNU project's 'zlib' compression library for the data size reduction compensates this rate gap. Through the first and second ({approx} no. 7132) LHD experimental campaigns, the LABCOM system acquired about 400 GB raw data, with maximum 120 MB per shot. These experiences proved that OO technology has great promise for the next generation of the data acquisition and storage system in fusion research experiments.

    We present a complex data handling system for the COMPASS tokamak, operated by IPP ASCR Prague, Czech Republic [1]. The system, called CDB (Compass DataBase), integrates different data sources as an assortment of data acquisition hardware and software from different vendors is used. Based on widely available open source technologies wherever possible, CDB is vendor and platform independent and it can be easily scaled and distributed. The data is directly stored and retrieved using a standard ...

  9. Trigger and data acquisition system for the ANTARES neutrino telescope

    The ANTARES collaboration is building a deep underwater neutrino telescope to be immersed in the Mediterranean Sea 40 km off the French coast. This detector will be able to detect the Cherenkov light emitted by muons produced in neutrino interactions using a three-dimensional matrix of optical sensors. The telescope will be made of nearly 1000 of these elementary units distributed over a wide area of about 0.1 km2 at an average depth of 2400 m. In order to reach a sub-nanosecond resolution on light pulse detection, signals from all OMs are analyzed and digitized locally before being sent to shore through a 50 km electro-optical cable. Front-end electronics, time alignment (clock distribution), triggering and data acquisition for such a large and remote detector represent a real challenge and required considerable R and D studies. The technical solutions adopted by the collaboration will be described and their performances discussed

  10. Data acquisition electronics for NESTOR experiment: project and tests

    The NESTOR detector, at present under construction, is a telescope for high-energy neutrino astronomy. The apparatus, based on Cherenkov light detection, will be deployed in deep sea (about 4000 m) near the S.W. Greek coast. We briefly describe the NESTOR detector, then we describe with more details the electronics for NESTOR data acquisition and transmission. The detector signals are sampled at 200 MHz and all the resulting information are transmitted to the laboratory on 30 km long electro-optical cable. The estimated Mean Time Between Failure of the full electronics system is greater than 20 years. Tests performed on the first prototypes confirm the main characteristics of these electronics: the dynamic range allowed for the signals is bigger than 1000, the pulse shape is reconstructed with an 8 bit ADC accuracy and the resolution in the measurement of the signal 'threshold crossing time' is better than 200 ps

    A new digital-based data acquisition system (DAQ) for Gammasphere has been developed. This system leverages the electronics designed for the GRETINA collaboration. At the center of this development are the GRETINA 10-channel digitizer modules which handle the Ge preamp signals at a 100MHz rate, and master trigger and router modules which allow triggers to be constructed from information obtained from the digitizer channels. The new DAQ increases event throughput significantly over the existing system while addressing multiple repair and maintenance issues. New hardware and firmware to integrate the DAQ with Gammasphere and its suite of ancillary detectors has been developed allowing for a seamless changeover from the analog DAQ to the new digital system. An overview of the system and illustrative results from several recent experiments will be presented. This material is based on work supported by the DOE, Office of Science, Office of Nuclear Physics under Contract No. DE-AC02-06CH11357.

    This paper describes the control and DAQ system of superconducting wigglers with magnetic field range up to 10.3 T. The first version of the system controls a 7 T superconducting wiggler prepared for installation at Bessy-II (Germany). The second one controls a 10 T wiggler which is under testing now at the SPring-8 site (Japan). Both systems are based on VME apparatus. The set of specialized VME modules is elaborated to arrange wiggler power supply control, full time wiggler monitoring, and magnetic field high accuracy measurement and field stabilization. The software for the control of the wigglers is written in C language for VxWorks operation system for a Motorola-162 VME controller. The task initialization, stops and acquisition of the data can be done from the nearest personal computer (FTP host for VME), or from the remote system as well.

  14. A computer program for testing equipment control and data acquisition

    Mostaco-Guidolin, Luiz C B; Galvao, Ricardo M O

    2009-01-01

    The software application described in this work aims to help with one of the main issues in experimental physics, the automation of data acquisition and equipment control. This software application, designated as SCTE, was written in Perl and uses the SCPI language to communicate with test instruments. The communication goes through RS-232 port, also known as serial port, vastly available in current generation PCs and testing equipment. Although the RS-232 port has been used here, SCTE may be easily adapted to work with USB or other kind of ports. SCTE enables the simultaneous control of several test equipment of different kinds, like oscilloscopes and signal generators, in order to automate an entire experiment. This program has been used to calibrate a new set of devices for power determination, part of the Alfven wave heating system of the tokamak TCABR.

  15. A flexible computerized system for environmental data acquisition and transmission

    Zappalà, G.

    2009-04-01

    In recent years increasing importance has been addressed to the knowledge of the marine environment, either to help detecting and understanding global climate change phenomena, or to protect and preserve those coastal areas, where multiple interests converge (linked to the tourism, recreational or productive activities…) and which suffer greater impact from anthropogenic activities; this has in turn stimulated the start of research programs devoted to the monitoring and surveillance of these particular zones, coupling the needs for knowledge, sustainable development and exploitation of natural resources. There is an increasing need to have data available in real time or near real time in order to intervene in emergency situations. Cabled or wireless data transmission can be used. The first allows the transmission of a higher amount of data only in coastal sites, while the second gives a bigger flexibility in terms of application to different environments; more, using mobile phone services (either terrestrial or satellite), it is possible to allocate the data centre in the most convenient place, without any need of proximity to the sea. Traditional oceanographic techniques, based on ship surveys, hardly fit the needs of operational oceanography, because of their high cost and fragmentary nature, both in spatial and temporal domains. To obtain a good synopticity, it is necessary to complement traditional ship observations with measurements from fixed stations (buoys moored in sites chosen to be representative of wider areas, or to constitute a sentinel against the arrival of pollutants), satellite observations, use of ships of opportunity and of newly developed instruments, like the gliders, or towed sliding devices, like the SAVE. Modern instruments rely on an electronic heart; an integrated hardware-software system developed in Messina is here presented, used in various versions to control data acquisition and transmission on buoys or on ship

    A web-base data acquisition and management system for GOSAT (Greenhouse gases Observation SATellite) validation lidar data-analysis has been developed. The system consists of data acquisition sub-system (DAS) and data management sub-system (DMS). DAS written in Perl language acquires AMeDAS (Automated Meteorological Data Acquisition System) ground-level local meteorological data, GPS Radiosonde upper-air meteorological data, ground-level oxidant data, skyradiometer data, skyview camera images, meteorological satellite IR image data and GOSAT validation lidar data. DMS written in PHP language demonstrates satellite-pass date and all acquired data. In this article, we briefly describe some improvement for higher performance and higher data usability. GPS Radiosonde upper-air meteorological data and U.S. standard atmospheric model in DAS automatically calculate molecule number density profiles. Predicted ozone density prole images above Saga city are also calculated by using Meteorological Research Institute (MRI) chemistry-climate model version 2 for comparison to actual ozone DIAL data.

    High energy physics experiments in KEK/Japan rush into over KHz trigger stage. Thus, we need a successor of the data acquisition(DAQ) system that replaces the CAMAC or FASTBUS systems. To meet these needs, we have developed a DAQ system which includes a crate, base-board modules, daughter cards for front-end A/D or T/D conversion, and back-end communication cards for data transfer and timing control. The size of the crate is for the 9U Euro-cards with the standard VME32 bus and extension connectors for power supply. The base-board comprises of a local bus with the sequencer connected to the front-end daughter cards via event buffering FIFOs, and the standard PMC (PCI mezzanine card) bus to be set a PMC processor unit to reduce data size from the front-end daughter cards. A data transfer module, which is connected to the event building system, and a trigger control unit, which communicates with the central timing controller are installed on the back-end communication card connected to the rear end of the base-...

  18. Waste retrieval sluicing system data acquisition system acceptance test report

    This document describes the test procedure for the Project W-320 Tank C-106 Sluicing Data Acquisition System (W-320 DAS). The Software Test portion will test items identified in the WRSS DAS System Description (SD), HNF-2115. Traceability to HNF-2115 will be via a reference that follows in parenthesis, after the test section title. The Field Test portion will test sensor operability, analog to digital conversion, and alarm setpoints for field instrumentation. The W-320 DAS supplies data to assist thermal modeling of tanks 241-C-106 and 241-AY-102. It is designed to be a central repository for information from sources that would otherwise have to be read, recorded, and integrated manually. Thus, completion of the DAS requires communication with several different data collection devices and output to a usable PC data formats. This test procedure will demonstrate that the DAS functions as required by the project requirements stated in Section 3 of the W-320 DAS System Description, HNF-2115

    Purpose: X-ray computed tomography (CT) is widely used, both clinically and preclinically, for fast, high-resolution anatomic imaging; however, compelling opportunities exist to expand its use in functional imaging applications. For instance, spectral information combined with nanoparticle contrast agents enables quantification of tissue perfusion levels, while temporal information details cardiac and respiratory dynamics. The authors propose and demonstrate a projection acquisition and reconstruction strategy for 5D CT (3D + dual energy + time) which recovers spectral and temporal information without substantially increasing radiation dose or sampling time relative to anatomic imaging protocols. Methods: The authors approach the 5D reconstruction problem within the framework of low-rank and sparse matrix decomposition. Unlike previous work on rank-sparsity constrained CT reconstruction, the authors establish an explicit rank-sparse signal model to describe the spectral and temporal dimensions. The spectral dimension is represented as a well-sampled time and energy averaged image plus regularly undersampled principal components describing the spectral contrast. The temporal dimension is represented as the same time and energy averaged reconstruction plus contiguous, spatially sparse, and irregularly sampled temporal contrast images. Using a nonlinear, image domain filtration approach, the authors refer to as rank-sparse kernel regression, the authors transfer image structure from the well-sampled time and energy averaged reconstruction to the spectral and temporal contrast images. This regularization strategy strictly constrains the reconstruction problem while approximately separating the temporal and spectral dimensions. Separability results in a highly compressed representation for the 5D data in which projections are shared between the temporal and spectral reconstruction subproblems, enabling substantial undersampling. The authors solved the 5D reconstruction
