The closure of Fermilab’s Tevatron this autumn will mark the end of an historic era in particle physics. But as physicists continue to comb through data from the Tevatron detectors, the laboratory will continue to pursue a greater understanding of the make-up of the Universe on multiple experimental frontiers.   In August 2010, construction crews began installing the roof over the enclosure that will house the NOvA detector. Photo by Dan Traska of Einarson Flying Service. “We plan to extract every bit of physics we can from this final Tevatron running period,” Fermilab Director Pier Oddone wrote in a column for Fermilab Today. “The Tevatron has already exceeded all expectations and, given the large data sets, we will continue to find new results and discoveries in the Tevatron data for years to come.” This spring, particle astrophysicists at Fermilab will ship to Chile components of a 570-megapixel camera scientists will install on the Blanco tele...

QA at Fermilab

Energy Technology Data Exchange (ETDEWEB)

Bodnarczuk, M.

1988-01-01

This paper opens with a brief overview of the purpose of Fermilab and historical synopsis of the development and current status of quality assurance (QA) at the Laboratory. The paper subsequently addresses some of the more important aspects of interpreting the national standard ANSI/ASME NQA-1 in pure research environments like Fermilab. Highlights of this discussion include, (1) what is hermeneutics and why are hermeneutical considerations relevant for QA, (2) a critical analysis of NQA-1 focussing on teleological aspects of the standard, (3) a description of the hermeneutical approach to NQA-1 used at Fermilab which attempts to capture the true intents of the document without violating the deeply ingrained traditions of quality standards and peer review that have been foundational to the overall success of the paradigms of high-energy physics.

The exploration of the vertically integrated circuits, also commonly known as 3D-IC technology, for applications in radiation detection started at Fermilab in 2006. This paper examines the opportunities that vertical integration offers by looking at various 3D designs that have been completed by Fermilab. The emphasis is on opportunities that are presented by through silicon vias (TSV), wafer and circuit thinning and finally fusion bonding techniques to replace conventional bump bonding. Early work by Fermilab has led to an international consortium for the development of 3D-IC circuits for High Energy Physics. The consortium has submitted over 25 different designs for the Fermilab organized MPW run organized for the first time.

Extruding plastic scintillator at Fermilab

International Nuclear Information System (INIS)

Pla-Dalmau, Anna; Bross, Alain D.; Rykalin, Viktor V.

2003-01-01

An understanding of the costs involved in the production of plastic scintillators and the development of a less expensive material have become necessary with the prospects of building very large plastic scintillation detectors. Several factors contribute to the high cost of plastic scintillating sheets, but the principal reason is the labor-intensive nature of the manufacturing process. In order to significantly lower the costs, the current casting procedures had to be abandoned. Since polystyrene is widely used in the consumer industry, the logical path was to investigate the extrusion of commercial-grade polystyrene pellets with dopants to yield high quality plastic scintillator. This concept was tested and high quality extruded plastic scintillator was produced. The D0 and MINOS experiments are already using extruded scintillator strips in their detectors. An extrusion line has recently been installed at Fermilab in collaboration with NICADD (Northern Illinois Center for Accelerator and Detector Development). This new facility will serve to further develop and improve extruded plastic scintillator. This paper will discuss the characteristics of extruded plastic scintillator and its raw materials, the different manufacturing techniques and the current R andD program at Fermilab

1991-06-01

In the past few years, ASIC (Application Specific Integrated Circuit) design has become important at Fermilab. The purpose of this paper is to present an overview of the in-house ASIC design activity which has taken place. This design effort has added much value to the high energy physics program and physics capability at Fermilab. The two approaches to ASIC development being pursued at Fermilab are examined by looking at some of the types of projects where ASICs are being used or contemplated. To help estimate the cost of future designs, a cost comparison is given to show the relative development and production expenses for these two ASIC approaches. 5 refs., 14 figs., 7 tabs

CPS and the Fermilab farms

Cooperative Processes Software (CPS) is a parallel programming toolkit developed at the Fermi National Accelerator Laboratory. It is the most recent product in an evolution of systems aimed at finding a cost-effective solution to the enormous computing requirements in experimental high energy physics. Parallel programs written with CPS are large-grained, which means that the parallelism occurs at the subroutine level, rather than at the traditional single line of code level. This fits the requirements of high energy physics applications, such as event reconstruction, or detector simulations, quite well. It also satisfies the requirements of applications in many other fields. One example is in the pharmaceutical industry. In the field of computational chemistry, the process of drug design may be accelerated with this approach. CPS programs run as a collection of processes distributed over many computers. CPS currently supports a mixture of heterogeneous UNIX-based workstations which communicate over networks with TCP/IR CPS is most suited for jobs with relatively low I/O requirements compared to CPU. The CPS toolkit supports message passing remote subroutine calls, process synchronization, bulk data transfers, and a mechanism called process queues, by which one process can find another which has reached a particular state. The CPS software supports both batch processing and computer center operations. The system is currently running in production mode on two farms of processors at Fermilab. One farm consists of approximately 90 IBM RS/6000 model 320 workstations, and the other has 85 Silicon Graphics 4D/35 workstations. This paper first briefly describes the history of parallel processing at Fermilab which lead to the development of CPS. Then the CPS software and the CPS Batch queueing system are described. Finally, the experiences of using CPS in production on the Fermilab processor farms are described.

Fermilab — originally called the National Accelerator Laboratory — began operations in Illinois on June 15, 1967. Operated and managed by The University of Chicago and Universities Research Association, LLC for the US Department of Energy, it has the distinction of being the only US national laboratory solely dedicated to the advancement of high-energy particle physics, astrophysics and cosmology. It has been the site of major discoveries and observations: the top and bottom quarks; the tau neutrino; direct CP violation in kaon decays; a quasar 27 billion light years away from us; origin of high-energy cosmic rays; and confirmation of the evidence of dark energy, among others. For 25 years it operated the world's highest energy particle collider, the Tevatron. Fermilab contributed collaboratively to the Tevatron's successor, the Large Hadron Collider, which discovered the Higgs boson in 2012. Fermilab's core competencies in accelerators, superconducting technologies, detectors and computing have positione...

FERMILAB: Main Injector

1993-01-01

The Fermilab Main Injector (FMI) project is the centerpiece of the Laboratory's Fermilab III programme for the 1990s. Designed to support a luminosity of at least 5x10 31 cm -2 s -1 in the Tevatron collider, it will also provide new capabilities for rare neutral kaon decay and neutrino oscillation studies. The Fermilab Main Injector 8-150 GeV synchrotron is designed to replace the existing Main Ring which seriously limits beam intensities for the Tevatron and the antiproton production target. The project has passed several significant milestones and is now proceeding rapidly towards construction. The project received a $11.65M appropriation in 1992 and has been given $15M for the current fiscal year. Through the Energy Systems Acquisition Advisory Board (ESAAB) process, the US Department of Energy (DoE) has authorized funds for construction of the underground enclosure and service building where the Main Injector will touch the Tevatron, and to the preparation of bids for remaining project construction

Report of the Fermilab Committee for Site Studies

2001-09-10

Fermilab is the flagship laboratory of the U.S. high-energy physics program. The Fermilab accelerator complex has occupied the energy frontier nearly continuously since its construction in the early 1970s. It will remain at the frontier until the Large Hadron Collider at CERN begins operating in 2006-7. A healthy future for Fermilab will likely require construction of a new accelerator in the post-LHC era. The process of identifying, constructing and operating a future forefront facility will require the support of the world high-energy-physics community, the governments and funding agencies of many nations and the people of surrounding communities. This report explores options for construction of a new facility on or near the existing Fermilab site. We began the study that forms the basis of this report with the idea that Fermilab, and the surrounding area of northeastern Illinois, possesses attributes that make it an attractive candidate for a new accelerator construction project: excellent geology; a Fermilab staff and local contractors who are experienced in subsurface construction; abundant energy supplies; good access to transportation networks; the presence of local universities with strong interest and participation in the Fermilab research program; Fermilab's demonstrated ability to mount large accelerator construction projects and operate complex accelerator facilities; and a surrounding community that is largely supportive of Fermilab's presence. Our report largely confirms these perceptions.

Fermilab and Latin America

International Nuclear Information System (INIS)

Lederman, Leon M.

2006-01-01

As Director of Fermilab, starting in 1979, I began a series of meetings with scientists in Latin America. The motivation was to stir collaboration in the field of high energy particle physics, the central focus of Fermilab. In the next 13 years, these Pan American Symposia stirred much discussion of the use of modern physics, created several groups to do collaborative research at Fermilab, and often centralized facilities and, today, still provides the possibility for much more productive North-South collaboration in research and education. In 1992, I handed these activities over to the AAAS, as President. This would, I hoped, broaden areas of collaboration. Such collaboration is unfortunately very sensitive to political events. In a rational world, it would be the rewards, cultural and economic, of collaboration that would modulate political relations. We are not there yet

LCLS-II is an upgrade project for the linear coherent light source (LCLS) at SLAC. The LCLS-II linac will consist of thirty-five 1.3 GHz and two 3.9 GHz superconducting RF continuous wave (CW) cryomodules that Fermilab and Jefferson Lab (JLab) will assemble in collaboration with SLAC. The LCLS-II 1.3 GHz cryomodule design is based on the European XFEL pulsed-mode cryomodule design with modifications needed for CW operation. Fermilab and JLab will each assemble and test a prototype 1.3 GHz cryomodule to assess the results of the CW modifications, in advance of 16 and 17 production 1.3 GHz cryomodules, respectively. Fermilab is solely responsible for the 3.9 GHz cryomodules. After the prototype cryomodule tests are complete and lessons learned incorporated, both laboratories will increase their cryomodule production rates to meet the challenging LCLS-II project requirement of approximately one cryomodule per month per laboratory. This paper presents the Fermilab Cryomodule Assembly Facility (CAF) infrastructure for LCLS-II cryomodule production, the Fermilab prototype 1.3 GHz CW cryomodule (pCM) assembly and readiness for production assembly.

Fermilab-Latin America collaboration

International Nuclear Information System (INIS)

Rubinstein, R.

1994-01-01

Fermilab's program of collaboration with Latin America was initiated by then-Director Leon Lederman about 1980. His goal was to aid Latin American physics, and particularly its particle physics; this latter aim is in keeping with the Laboratory's particle physics mission. The reasons for collaboration between institutions in the US and Latin America are many, including geographic and cultural, together with the existence of many talented scientists and many centers of excellence in the region. There are also broader reasons; for example, it has been stated frequently that physics is the basis of much technology, and advanced technology is a necessity for a country's development. There is nothing unique about Fermilab's program; other US institutions can carry out similar activities, and some have carried out individual items in the past. On the Latin American side, such collaboration enables institutions there to carry out forefront physics research, and also to have the advantages of particle physics spin-offs, both in expertise in related technologies and in scientist training. In addition to particle physics, collaboration is possible in many other related areas. Although particle physics is frequently viewed as open-quotes big scienceclose quotes, all of the large research groups in the field are composed of many small university groups, each of which contributes to the experiment, the analysis and the physics. Fermilab is an international laboratory, open to all users; a research proposal is accepted on scientific merit and technical competence, not on the country of origin of the scientists making the proposal. Currently, of Fermilab's approximately 1400 users, about 30% are from non-US institutions. It should be noted here that Fermilab's funds, which come from the US government, are for particle physics only; however, there is some flexibility in interpretation of this

The Fermilab control system, ACNET, is used for controlling the Tevatron and all of its pre-accelerators. However, other smaller experiments at Fermilab have been using different controls systems, in particular DOOCS and EPICS. This paper reports some of the steps taken at Fermilab to integrate support for these outside systems. We will describe specific tools that we have built or adapted to facilitate interaction between the architectures. We also examine some of the difficulties that arise from managing this heterogeneous environment. Incompatibilities as well as common elements will be described.

The promise for great discoveries is huge, and many of the plans for our future depend on LHC results. Those of us planning national programmes in anticipation of data from the LHC face formidable challenges to develop future facilities that are complementary to the LHC, whatever the physics discoveries may be. At Fermilab, this has led us to move forcefully with a programme at the intensity frontier, where experiments with neutrinos and rare decays open a complementary window into nature.

The Fermilab antihydrogen program

CERN Document Server

Mandelkern, M A

1999-01-01

The antihydrogen atom, the bound state of an antiproton and a positron, is the antiparticle of the hydrogen stem. Until very recently no antimatter atoms had been observed. Experiments at CERN and Fermilab have reported observations of small amounts of antihydrogen but are in sharp disagreement. At Fermilab we have produced a background-free sample of 66 atoms. CPT invariance predicts that the spectrum and the lifetimes of antihydrogen states are identical to those of hydrogen. This fundamental symmetry has not been tested in atoms. Experiments for the further study of antihydrogen are planned for both laboratories. At CERN a new antiproton accumulator is expected to facilitate the trapping of cold antihydrogen, followed by high precision spectroscopic measurements. At Fermilab an interferometric technique analogous to measurement of the K/sub S/K/sub L/ mass difference will be used to determine the n =2 antihydrogen spectrum using a beam of high momentum antihydrogen atoms.

Control system for Fermilab`s low temperature upgrade

Energy Technology Data Exchange (ETDEWEB)

Norris, B.L.

1996-09-01

Fermilab recently upgraded the Tevatron Cryogenic Systems to allow for lower temperature operation. This Lower Temperature Upgrade grew out of a desire to increase the Colliding Beam Physics energy from 900 GeV to 1000 GeV. A key element in achieving this goal is the new cryogenic control system designed at Fermilab and installed in 24 satellite refrigerators and 8 compressor buildings. The cryogenic improvements and addition hardware like cold compressors exceeded the capability of the original distributed controls package. The new distributed controls package uses a Multibus II platform and Intel`s 80386 microprocessor. Token Ring is used as the link to the systems 6 primary crate locations with Arcnet used as the connection to the systems numerous I/O crates. I/0 capabilities are double the capabilities of the original system. Software has also been upgraded with the introduction of more flexible control loop strategies and Finite State Machines used for automatic sequential control, like quench recovery or cold compressor pump down.

The FabrIc for Frontier Experiments (FIFE) project is an initiative within the Fermilab Scientific Computing Division designed to steer the computing model for non-LHC Fermilab experiments across multiple physics areas. FIFE is a collaborative effort between experimenters and computing professionals to design and develop integrated computing models for experiments of varying size, needs, and infrastructure. The major focus of the FIFE project is the development, deployment, and integration of solutions for high throughput computing, data management, database access and collaboration management within an experiment. To accomplish this goal, FIFE has developed workflows that utilize Open Science Grid compute sites along with dedicated and commercial cloud resources. The FIFE project has made significant progress integrating into experiment computing operations several services including a common job submission service, software and reference data distribution through CVMFS repositories, flexible and robust data transfer clients, and access to opportunistic resources on the Open Science Grid. The progress with current experiments and plans for expansion with additional projects will be discussed. FIFE has taken the leading role in defining the computing model for Fermilab experiments, aided in the design of experiments beyond those hosted at Fermilab, and will continue to define the future direction of high throughput computing for future physics experiments worldwide.

Physics at a New Fermilab Proton Driver

2005-01-01

In 2004 the Fermilab Long Range Planning Committee identified a new high intensity Proton Driver as an attractive option for the future, primarily motivated by the recent exciting developments in neutrino physics. The Fermilab Director has requested further development of the physics case for a new Fermilab Proton Driver, exploring both its ability to support a World class neutrino program, and the other physics opportunities it would provide. A physics study has been ongoing for the last 6 months. The emerging physics case will be presented.

Fermilab is a basic research high-energy physics laboratory operated by Universities Research Association, Inc. under contract to the U.S. Department of Energy. Fermilab researchers utilize the Tevatron particle accelerator (currently the worlds most powerful accelerator) to better understand subatomic particles as they exist now and as they existed near the birth of the universe. A collection review of the Fermilab Library monographs was conducted during the summers of 1998 and 1999. While some items were identified for deselection, the review proved most fruitful in highlighting some of the strengths of the Fermilab monograph collection. One of these strengths is history of physics, including biographies and astrophysics. A bibliography of the physics history books in the collection as of Summer, 1999 follows, arranged by author. Note that the call numbers are Library of Congress classification

The Muon g-2 experiment at Fermilab

Energy Technology Data Exchange (ETDEWEB)

Chapelain, Antoine [Cornell U., Phys. Dept.

2017-01-01

The upcoming Fermilab E989 experiment will measure the muon anomalous magnetic moment aμ. This measurement is motivated by the previous measurement performed in 2001 by the BNL E821 experiment that reported a 3-4 standard deviation discrepancy between the measured value and the Standard Model prediction. The new measurement at Fermilab aims to improve the precision by a factor of four reducing the total uncertainty from 540 parts per billion (BNL E821) to 140 parts per billion (Fermilab E989). This paper gives the status of the experiment.

2015 Fermilab Laboratory Directed Research & Development Annual Report

The Fermi National Accelerator Laboratory (FNAL) is conducting a Laboratory Directed Research and Development (LDRD) program. Fiscal year 2015 represents the first full year of LDRD at Fermilab and includes seven projects approved mid-year in FY14 and six projects approved in FY15. One of the seven original projects has been completed just after the beginning of FY15. The implementation of LDRD at Fermilab is captured in the approved Fermilab 2015 LDRD Annual Program Plan. In FY15, the LDRD program represents 0.64% of Laboratory funding. The scope of the LDRD program at Fermilab will be established over the next couple of years where a portfolio of about 20 on-going projects representing approximately between 1% and 1.5% of the Laboratory funding is anticipated. This Annual Report focuses on the status of the current projects and provides an overview of the current status of LDRD at Fermilab.

2014 Fermilab Laboratory Directoed Research & Development Annual Report

Wester, W. [Fermi National Accelerator Lab. (FNAL), Batavia, IL (United States)

2016-05-26

After initiation by the Fermilab Laboratory Director, a team from the senior Laboratory leadership and a Laboratory Directed Research and Development (LDRD) Advisory Committee developed an implementation plan for LDRD at Fermilab for the first time. This implementation was captured in the approved Fermilab 2014 LDRD Program Plan and followed directions and guidance from the Department of Energy (DOE) order, DOE O 413.2B, a “Roles, Responsibilities, and Guidelines, …” document, and examples of best practices at other DOE Office of Science Laboratories. At Fermilab, a FY14 midyear Call for Proposals was issued. A LDRD Selection Committee evaluated those proposals that were received and provided a recommendation to the Laboratory Director who approved seven LDRD projects. This Annual Report focuses on the status of those seven projects and provides an overview of the current status of LDRD at Fermilab. The seven FY14 LDRD approved projects had a date of initiation late in FY14 such that this report reflects approximately six months of effort approximately through January 2015. The progress of these seven projects, the subsequent award of six additional new projects beginning in FY15, and preparations for the issuance of the FY16 Call for Proposals indicates that LDRD is now integrated into the overall annual program at Fermilab. All indications are that LDRD is improving the scientific and technical vitality of the Laboratory and providing new, novel, or cutting edge projects carried out at the forefront of science and technology and aligned with the mission and strategic visions of Fermilab and the Department of Energy.

Fermilab research program workbook

Rubinstein, R.

1983-05-01

The Fermilab Research Program Workbook has been produced annually for the past several years, with the original motivation of assisting the Physics Advisory Committee in its yearly program review conducted during its summer meeting. While this is still the primary goal, the Workbook is increasingly used by others needing information on the current status of Fermilab experiments, properties of beams, and short summaries of approved experiments. At the present time, considerable changes are taking place in the facilities at Fermilab. We have come to the end of the physics program using the 400 GeV Main Ring, which is now relegated to be just an injector for the soon-to-be commissioned Tevatron. In addition, the experimental areas are in the midst of a several-year program of upgrading to 1000 GeV capability. Several new beam lines will be built in the next few years; some indications can be given of their properties, although with the caveat that designs for some are by no means final. Already there is considerable activity leading to experiments studying anti p p collisions at √s = 2000 GeV

DART is the new data acquisition system designed and implemented for six Fermilab experiments by the Fermilab Computing Division and the experiments themselves. The complexity of the experiments varies greatly. Their data taking throughput and event filtering requirements range from a few (2-5) to tens (80) of CAMAC, FASTBUS and home built front end crates; from a few 100 KByte/sec to 160 MByte/sec front end data collection rates; and from 0-3000 Mips of level 3 processing. The authors report on the architecture and implementation of DART to this date, and the hardware and software components that are being developed and supported

CERN-Fermilab summer school is smash hit

CERN Multimedia

2006-01-01

A new joint CERN-Fermilab summer school is proving more popular than the organizers ever imagined. Interest in the first CERN-Fermilab Hadron Collider Physics Summer School, to be held at Fermilab on 9-18 August, has proved far greater than anyone anticipated, with 300 applications for the planned 100 places. In response, the Organizing Committee, led by Fermilab's Jeffrey Appel and Bogdan Dobrescu, has had to increase the class size to nearly 150 participants. 'The success of this initiative, with an unexpectedly large number of applications, shows both the great anticipation that exists in the world for the start up of the LHC, and the need for greater educational support to enable the hundreds of young researchers to get ready for a full and prompt exploitation of the LHC data,' explains CERN's Michelangelo Mangano, who is a member of the International Advisory Committee (IAC) for the school. 'Fulfilling the expectations of the students will be a great challenge, which we are all eager to tackle.' Fabiol...

Proposed Fermilab upgrade main injector project

International Nuclear Information System (INIS)

1992-04-01

The US Department of Energy (DOE) proposes to construct and operate a ''Fermilab Main Injector'' (FMI), a 150 GeV proton injector accelerator, at the Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois. The purpose and need for this action are given of this Environmental Assessment (EA). A description of the proposed FMI and construction activities are also given. The proposed FMI would be housed in an underground tunnel with a circumference of approximately 2.1 miles (3.4 kilometers), and the construction would affect approximately 135 acres of the 6,800 acre Fermilab site. The purpose of the proposed FMI is to construct and bring into operation a new 150 GeV proton injector accelerator. This addition to Fermilab's Tevatron would enable scientists to penetrate ever more deeply into the subatomic world through the detection of the super massive particles that can be created when a proton and antiproton collide head-on. The conversion of energy into matter in these collisions makes it possible to create particles that existed only an instant after the beginning of time. The proposed FMI would significantly extend the scientific reach of the Tevatron, the world's first superconducting accelerator and highest energy proton-antiproton collider

A review of the Fermilab fixed-target program

Energy Technology Data Exchange (ETDEWEB)

Rameika, R. [Fermi National Accelerator Lab., Batavia, IL (United States)

1994-12-01

All eyes are now on the Fermilab collider program as the intense search for the top quark continues. Nevertheless, Fermilab`s long tradition of operating a strong, diverse physics program depends not only on collider physics but also on effective use of the facilities the Laboratory was founded on, the fixed-target beamlines. In this talk the author presents highlights of the Fermilab fixed-target program from its (not too distant) past, (soon to be) present, and (hopefully, not too distant) future program. The author concentrates on those experiments which are unique to the fixed-target program, in particular hadron structure measurements which use the varied beams and targets available in this mode and the physics results from kaon, hyperon and high statistics charm experiments which are not easily accessible in high p{sub T} hadron collider detectors.

As part of the Fermilab/KISTI cooperative research project, Fermilab has successfully run an experimental simulation workflow at scale on a federation of Amazon Web Services (AWS), FermiCloud, and local FermiGrid resources. We used the CernVM-FS (CVMFS) file system to deliver the application software. We established Squid caching servers in AWS as well, using the Shoal system to let each individual virtual machine find the closest squid server. We also developed an automatic virtual machine conversion system so that we could transition virtual machines made on FermiCloud to Amazon Web Services. We used this system to successfully run a cosmic ray simulation of the NOvA detector at Fermilab, making use of both AWS spot pricing and network bandwidth discounts to minimize the cost. On FermiCloud we also were able to run the workflow at the scale of 1000 virtual machines, using a private network routable inside of Fermilab. We present in detail the technological improvements that were used to make this work a reality. (paper)

A focusing lens R&D program is close to completion and industrial production of magnets has begun. Two types of magnets are being built for use in the room temperature RF section at the front end of a superconducting H-minus linac of a High Intensity Neutrino Source. All of the magnets are designed as a solenoid with bucking coils to cancel the field in the vicinity of adjacent RF cavities, and one type incorporates steering dipole corrector coils. We present a summary of the predicted and measured quench and magnetic properties for both R&D and production device samples that have been tested at Fermilab.

Strategic directions of computing at Fermilab

Wolbers, Stephen

1998-05-01

Fermilab computing has changed a great deal over the years, driven by the demands of the Fermilab experimental community to record and analyze larger and larger datasets, by the desire to take advantage of advances in computing hardware and software, and by the advances coming from the R&D efforts of the Fermilab Computing Division. The strategic directions of Fermilab Computing continue to be driven by the needs of the experimental program. The current fixed-target run will produce over 100 TBytes of raw data and systems must be in place to allow the timely analysis of the data. The collider run II, beginning in 1999, is projected to produce of order 1 PByte of data per year. There will be a major change in methodology and software language as the experiments move away from FORTRAN and into object-oriented languages. Increased use of automation and the reduction of operator-assisted tape mounts will be required to meet the needs of the large experiments and large data sets. Work will continue on higher-rate data acquisition systems for future experiments and projects. R&D projects will be pursued as necessary to provide software, tools, or systems which cannot be purchased or acquired elsewhere. A closer working relation with other high energy laboratories will be pursued to reduce duplication of effort and to allow effective collaboration on many aspects of HEP computing.

Neutrino experimentation at higher energies was among the justifications for the construction of Fermilab and the earliest studies utilized these new beams produced with 350-400 GeV protons. This pre-Tevatron period used both electronic counters and the new 15-foot cryogenic bubble chamber. The counter experimental programme was basically divided into two generations. The first covered the discovery of new phenomena and confirmation of the parton model using high rate wide-band and the first dichromatic narrow-band neutrino beams. The second concentrated on precision measurements with dichromatic beams. One flagship experiment, designated ''E1 A'', was originally a collaboration of Harvard, Pennsylvania and Wisconsin, and was the prototype of large neutrino calorimeters: a target/ calorimeter followed by a large set of iron toroidal magnets. E1A and its successor, E310 (which included Rutgers), ran for a total of 6,650 hours from 1972 through 1978. Contemporary with these experiments was another large counter experiment by CalTech and Fermilab, designated originally as E21 A. Along with its successors, E262, E320, and E356 (which collected data* over some 4,600h) it took part in the first generation programme, and subsequently spearheaded the second generation with precision measurements of both charged current structure functions and the weak mixing angle. Finally, this latter collaboration extended its participation into the early Tevatron era, and will continue through the 1990s

Fully operational in June of 1994, the Fermilab ISDN Pilot Project was started to gain insight into the costs and benefits of providing ISDN service to the homes of Fermilab researchers. Fourteen users were chosen from throughout Fermilab, but the number of Fermilab-employed spouses pushed the total user count to 20. Each home was equipped with a basic rate ISDN (BRI) line, a BRI Ethernet half-bridge, and an NT-1. An inter-departmental team coordinated the project. Usage at each home was tracked and frequent surveys were attempted. Lessons learned include: working with Ameritech can be difficult; careful monitoring is essential; and configuration of home computing equipment is very time consuming. Plans include moving entirely to primary rate ISDN hubs, support for different home ISDN equipment and better usage and performance tracking.

Two decades of Mexican particle physics at Fermilab

2002-01-01

This report is a view from Fermilab of Mexican particle physics at the Laboratory since about 1980; it is not intended to be a history of Mexican particle physics: that topic is outside the expertise of the writer. The period 1980 to the present coincides with the growth of Mexican experimental particle physics from essentially no activity to its current state where Mexican groups take part in experiments at several of the world's major laboratories. Soon after becoming Fermilab director in 1979, Leon Lederman initiated a program to encourage experimental physics, especially experimental particle physics, in Latin America. At the time, Mexico had significant theoretical particle physics activity, but none in experiment. Following a visit by Lederman to UNAM in 1981, a conference ''Panamerican Symposium on Particle Physics and Technology'' was held in January 1982 at Cocoyoc, Mexico, with about 50 attendees from Europe, North America, and Latin America; these included Lederman, M. Moshinsky, J. Flores, S. Glashow, J. Bjorken, and G. Charpak. Among the conference outcomes were four subsequent similar symposia over the next decade, and a formal Fermilab program to aid Latin American physics (particularly particle physics); it also influenced a decision by Mexican physicist Clicerio Avilez to switch from theoretical to experimental particle physics. The first physics collaboration between Fermilab and Mexico was in particle theory. Post-docs Rodrigo Huerta and Jose Luis Lucio spent 1-2 years at Fermilab starting in 1981, and other theorists (including Augusto Garcia, Arnulfo Zepeda, Matias Moreno and Miguel Angel Perez) also spent time at the Laboratory in the 1980s

Design Considerations for Proposed Fermilab Integrable RCS

Energy Technology Data Exchange (ETDEWEB)

Eldred, Jeffrey [Fermilab; Valishev, Alexander

2017-03-02

Integrable optics is an innovation in particle accelerator design that provides strong nonlinear focusing while avoiding parametric resonances. One promising application of integrable optics is to overcome the traditional limits on accelerator intensity imposed by betatron tune-spread and collective instabilities. The efficacy of high-intensity integrable accelerators will be undergo comprehensive testing over the next several years at the Fermilab Integrable Optics Test Accelerator (IOTA) and the University of Maryland Electron Ring (UMER). We propose an integrable Rapid-Cycling Synchrotron (iRCS) as a replacement for the Fermilab Booster to achieve multi-MW beam power for the Fermilab high-energy neutrino program. We provide a overview of the machine parameters and discuss an approach to lattice optimization. Integrable optics requires arcs with integer-pi phase advance followed by drifts with matched beta functions. We provide an example integrable lattice with features of a modern RCS - long dispersion-free drifts, low momentum compaction, superperiodicity, chromaticity correction, separate-function magnets, and bounded beta functions.

The Fermilab central computing facility architectural model

Nicholls, J.

1989-01-01

The goal of the current Central Computing Upgrade at Fermilab is to create a computing environment that maximizes total productivity, particularly for high energy physics analysis. The Computing Department and the Next Computer Acquisition Committee decided upon a model which includes five components: an interactive front-end, a Large-Scale Scientific Computer (LSSC, a mainframe computing engine), a microprocessor farm system, a file server, and workstations. With the exception of the file server, all segments of this model are currently in production: a VAX/VMS cluster interactive front-end, an Amdahl VM Computing engine, ACP farms, and (primarily) VMS workstations. This paper will discuss the implementation of the Fermilab Central Computing Facility Architectural Model. Implications for Code Management in such a heterogeneous environment, including issues such as modularity and centrality, will be considered. Special emphasis will be placed on connectivity and communications between the front-end, LSSC, and workstations, as practiced at Fermilab. (orig.)

Wester, W. [Fermi National Accelerator Lab. (FNAL), Batavia, IL (United States)

2016-05-25

Fermilab is executing Laboratory Directed Research and Development (LDRD) as outlined by order DOE O 413.2B in order to enhance and realize the mission of the laboratory in a manner that also supports the laboratory’s strategic objectives and the mission of the Department of Energy. LDRD funds enable scientific creativity, allow for exploration of “high risk, high payoff” research, and allow for the demonstration of new ideas, technical concepts, and devices. LDRD also has an objective of maintaining and enhancing the scientific and technical vitality of Fermilab. LDRD is able to fund employee-initiated proposals that address the current strategic objectives and better position Fermilab for future mission needs. The request for such funds is made in consideration of the investment needs, affordability, and directives from DOE and Congress. Review procedures of the proposals will insure that those proposals which most address the strategic goals of the DOE and the Laboratory or which best position Fermilab for the future will be recommended to the Laboratory Director who has responsibility for approval. The execution of each approved project will be the responsibility of the Principal Investigator, PI, who will follow existing Laboratory guidelines to ensure compliance with safety, environmental, and quality assurance practices. A Laboratory Director-appointed LDRD Coordinator will work with Committees, Laboratory Management, other Fermilab Staff, and the PI’s to oversee the implementation of policies and procedures of LDRD and provide the management and execution of this Annual Program Plan. FY16 represents third fiscal year in which LDRD has existed at Fermilab. The number of preliminary proposals (117) submitted in response to the LDRD Call for Proposals indicates very strong interest of the program within the Fermilab community. The first two Calls have resulted in thirteen active LDRD projects – and it is expected that between five and seven new

Review of programmable systems associated with Fermilab experiments

Nash, T.

1981-05-01

The design and application of programmable systems for Fermilab experiments are reviewed. The high luminosity fixed target environment at Fermilab has been a very fertile ground for the development of sophisticated, powerful triggering systems. A few of these are integrated systems designed to be flexible and to have broad application. Many are dedicated triggers taking advantage of large scale integrated circuits to focus on the specific needs of one experiment. In addition, the data acquisition requirements of large detectors, existing and planned, are being met with programmable systems to process the data. Offline reconstruction of data places a very heavy load on large general purpose computers. This offers a potentially very fruitful area for new developments involving programmable dedicated systems. Some of the present thinking at Fermilab regarding offline reconstruction processors will be described

Fermilab supports a scientific program that includes experiments and scientists located across the globe. To better serve this community, in 2004, the (then) Computing Division undertook the strategy of placing all of the High Throughput Computing (HTC) resources in a Campus Grid known as FermiGrid, supported by common shared services. In 2007, the FermiGrid Services group deployed a service infrastructure that utilized Xen virtualization, LVS network routing and MySQL circular replication to deliver highly available services that offered significant performance, reliability and serviceability improvements. This deployment was further enhanced through the deployment of a distributed redundant network core architecture and the physical distribution of the systems that host the virtual machines across multiple buildings on the Fermilab Campus. In 2010, building on the experience pioneered by FermiGrid in delivering production services in a virtual infrastructure, the Computing Sector commissioned the FermiCloud, General Physics Computing Facility and Virtual Services projects to serve as platforms for support of scientific computing (FermiCloud 6 GPCF) and core computing (Virtual Services). This work will present the evolution of the Fermilab Campus Grid, Virtualization and Cloud Computing infrastructure together with plans for the future.

The Strategic Value of Affiliation Partnerships in Securing Future Relevance.

Science.gov (United States)

Saunders, Ninfa M

2017-01-01

Finding the best route to navigate the changing landscape of healthcare has become an obsession for many organizations. Their quest to stay competitive, significant, and ultimately relevant is a continuous discovery process. Many hospitals and health systems have considered affiliations and partnerships as important tactical options. Partnerships can range from loose arrangements, such as nonequity collaborations and management agreements, to total affiliation, as in a merger and acquisition. Whichever option an organization decides to pursue, a comprehensive assessment is necessary to find the best partner-the right fit. Addressing the "why," "when," "how," and "with whom" questions is fundamental. Having the depth and breadth of resources to manage the discovery process is equally important.Learning from others who have experienced this journey is helpful, as is the support of industry experts. However, one task that cannot be delegated is discerning whether affiliation is right for an organization. That is the responsibility of an organization's leadership team, which must consider the dynamic forces in play when evaluating an affiliation partnership. Many of the suggested modalities revolve around how the affiliation partnership can provide a value proposition for the entities involved. Furthermore, inevitable challenges emerge when fiercely independent and successful organizations come together at different levels of need and readiness. Anticipating and providing for the potential exit of any member are matters that the partnership must accept and prepare for, and the ability to execute can make or break the trajectory toward a value proposition. A strong resolve to monitor, measure, calibrate, and recalibrate can give a partnership the agility to pivot toward relevance and sustainability.Stratus Healthcare applied principles of alignment and affiliation in creating the largest collaborative partnership of hospitals in the southeastern United States.

Board affiliation and pay gap

Directory of Open Access Journals (Sweden)

Shenglan Chen

2014-06-01

Full Text Available This paper examines the effects of board affiliation on the corporate pay gap. Using a sample of Chinese listed firms from 2005 to 2011, we find that boards with a greater presence of directors appointed by block shareholders have lower pay gaps. Furthermore, the governance effects of board affiliation with and without pay are distinguished. The empirical results show that board affiliation without pay is negatively related to the pay gap, while board affiliation with pay is positively related to the pay gap. Overall, the results shed light on how block shareholders affect their companies’ pay gaps through board affiliation.

Report of the Fermilab ILC Citizens' Task Force

2008-06-01

Fermi National Accelerator Laboratory convened the ILC Citizens' Task Force to provide guidance and advice to the laboratory to ensure that community concerns and ideas are included in all public aspects of planning and design for a proposed future accelerator, the International Linear Collider. In this report, the members of the Task Force describe the process they used to gather and analyze information on all aspects of the proposed accelerator and its potential location at Fermilab in northern Illinois. They present the conclusions and recommendations they reached as a result of the learning process and their subsequent discussions and deliberations. While the Task Force was charged to provide guidance on the ILC, it became clear during the process that the high cost of the proposed accelerator made a near-term start for the project at Fermilab unlikely. Nevertheless, based on a year of extensive learning and dialogue, the Task Force developed a series of recommendations for Fermilab to consider as the laboratory develops all successor projects to the Tevatron. The Task Force recognizes that bringing a next-generation particle physics project to Fermilab will require both a large international effort and the support of the local community. While the Task Force developed its recommendations in response to the parameters of a future ILC, the principles they set forth apply directly to any large project that may be conceived at Fermilab, or at other laboratories, in the future. With this report, the Task Force fulfills its task of guiding Fermilab from the perspective of the local community on how to move forward with a large-scale project while building positive relationships with surrounding communities. The report summarizes the benefits, concerns and potential impacts of bringing a large-scale scientific project to northern Illinois.

Dedicating Fermilab's Collider

It was a bold move to have a fullscale dedication ceremony for the new proton-antiproton Collider at the Fermilab Tevatron on 13 October, two days before the first collisions were seen. However the particles dutifully behaved as required, and over the following weekend the Collider delivered its goods at a total energy of 1600 GeV, significantly boosting the world record for laboratory collisions.

Religiosity and the Motivation for Social Affiliation.

Science.gov (United States)

Van Cappellen, Patty; Fredrickson, Barbara L; Saroglou, Vassilis; Corneille, Olivier

2017-07-15

Although universal, the motivation to affiliate can vary as a function of individual differences and of the characteristics of the target. Three studies explored the extent to which religious beliefs and identity are related to social affiliation motivation. Because most religions advocate affiliation and provide opportunities for frequent experiences of affiliation, we reasoned that religious people might show greater affiliation motivation in everyday attitudes and behaviors. We found that religiosity was positively related to implicit and behavioral measures of general social affiliation (Studies 1 and 2). However, manipulating the identity of the affiliation target revealed that when affiliating might not lead to positive outcomes, the relation between religiosity and social affiliation disappeared (but did not reverse). In Studies 2 and 3, when the target of the affiliation was explicitly identified as a member of a threatening out-group (atheist), religiosity did not predict affiliation behaviors. We discuss the mechanisms by which religiosity motivates and constrains social affiliation and the potential implications for social influence and intergroup processes.

Conrad, J.

1994-11-01

This paper highlights the results of the Fermilab Fixed Target Program that were announced between October, 1993 and October, 1994. These results are drawn from 18 experiments that took data in the 1985, 1987 and 1990/91 fixed target running periods. For this discussion, the Fermilab Fixed Target Program is divided into 5 major topics: hadron structure, precision electroweak measurements, heavy quark production, polarization and magnetic moments, and searches for new phenomena. However, it should be noted that most experiments span several subtopics. Also, measurements within each subtopic often affect the results in other subtopics. For example, parton distributions from hadron structure measurements are used in the studies of heavy quark production

The models run on Unix workstations, communicating with legacy controls software through a front end redirection mechanism (the open access server), a relational database and a simple text-based protocol over TCP/IP. The clients and the server are implemented in object-oriented C++. We discuss limitations of our approach and the difficulties that arise from it. Some of the obstacles may be overcome by introducing a new layer of abstraction. To maintain compatibility with the next generation of accelerator control software currently under development at the laboratory, this layer would be implemented in Java.

Berman, E.F.

1998-01-01

Because of the critical nature of DA/Online software it is important to commission software which is correct, usable, reliable, and maintainable, i.e., has the highest quality possible. In order to help meet these goals Fermi National Accelerator Laboratory (Fermilab) has begun implementing a formal software inspection process. Formal Inspections are used to reduce the number of defects in software at as early a stage as possible. These Inspections, in use at a wide variety of institutions (e.g., NASA, Motorola), implement a well-defined procedure that can be used to improve the quality of many different types of deliverables. The inspection process, initially designed by Michael Fagan, will be described as it was developed and as it is currently implemented at Fermilab where it has been used to improve the quality of a variety of different experiment DA/Online software. Benefits of applying inspections at many points in the software life-cycle and benefits to the people involved will be investigated. Experience with many different types of Inspections and the lessons learned about the inspection process itself will be detailed. Finally, the future of Inspections at Fermilab will be given

The development of the Fermilab accelerator complex during the past two decades from its concept as the ''200 BeV accelerator'' to that of the present tevatron, designed to operate at energies as high as 1 TeV, has required a coincidental refinement and development in methods of shielding design. In this paper I describe these methods as used by the radiation protection staff of Fermilab. This description will review experimental measurements which substantiate these techniques in realistic situations. Along the way, observations will be stated which likely are applicable to other protron accelerators in the multi-hundred GeV energy region, including larger ones yet to be constructed

2013-03-22

The antiproton source for a proton-antiproton collider at Fermilab was proposed in 1976 [1]. The proposal argued that the requisite luminosity (~10²⁹ cm^-2sec^-1) could be achieved with a facility that would produce and cool approximately 10¹¹ antiprotons per day. Funding for the Tevatron I project (to construct the Antiproton source) was initiated in 1981 and the Tevatron ring itself was completed, as a fixed target accelerator, in the summer of 1983 and the Antiproton Source was completed in 1985. At the end of its operations in 2011, the Fermilab antiproton production complex consisted of a sophisticated target system, three 8-GeV storage rings (namely the Debuncher, Accumulator and Recycler), 25 independent multi-GHz stochastic cooling systems, the world’s only relativistic electron cooling system and a team of technical experts equal to none. Sustained accumulation of antiprotons was possible at the rate of greater than 2.5×10¹¹ per hour. Record-size stacks of antiprotons in excess of 3×10¹² were accumulated in the Accumulator ring and 6×10¹² in the Recycler. In some special cases, the antiprotons were stored in rings for more than 50 days. Note, that over the years, some 10¹⁶ antiprotons were produced and accumulated at Fermilab, which is about 17 nanograms and more than 90% of the world’s total man-made quantity of nuclear antimatter. The accelerator complex at Fermilab supported a broad physics program including the Tevatron Collider Run II [2], neutrino experiments using 8 GeV and 120 GeV proton beams, as well as a test beam facility and other fixed target experiments using 120 GeV primary proton beams. The following sections provide a brief description of Fermilab accelerators as they operated at the end of the Collider Run II (2011).

CERN-Fermilab Hadron Collider Physics Summer School 2013 open for applications

CERN Multimedia

2013-01-01

Mark your calendar for 28 August - 6 September 2013, when CERN will welcome students to the eighth CERN-Fermilab Hadron Collider Physics Summer School.   Experiments at hadron colliders will continue to provide our best tools for exploring physics at the TeV scale for some time. With the completion of the 7-8 TeV runs of the LHC, and the final results from the full Tevatron data sample becoming available, a new era in particle physics is beginning, heralded by the Higgs-like particle recently discovered at 125 GeV. To realize the full potential of these developments, CERN and Fermilab are jointly offering a series of "Hadron Collider Physics Summer Schools", to prepare young researchers for these exciting times. The school has alternated between CERN and Fermilab, and will return to CERN for the eighth edition, from 28 August to 6 September 2013. The CERN-Fermilab Hadron Collider Physics Summer School is an advanced school which particularly targets young postdocs in exper...

Check Mate! The CERN vs Fermilab Chess Competition

CERN Multimedia

2001-01-01

7,000 kilometers and a 7 hour time difference had no impact upon the enthusiasm that pervaded the chess competition between CERN and Fermilab. In spite of the computer era, one game was played over a real wooden board.  Tomas Davidek and Irwin Gaines took advantage of Irwin's momentary presence at CERN. Several chess servers span the world and they are used by all sorts of people from many walks of life. However in mid-November on freechess.org there was a sudden influx of physicists as CERN and Fermilab faced off in their first online chess match. While technically a competition, the aim of the match was above all a 'friendly' contest between the two sister labs.  Usually, in serious chess competitions, each team plays in its strongest available constellation at the moment of the match.  But both CERN and Fermilab did quite the opposite and made getting all interested players involved the top priority. 'This was all put together for the purpose of having good fun' said Tibor Sim...

Contribution of company affiliation and social contacts to risk estimates of between-farm transmission of avian influenza.

Science.gov (United States)

Leibler, Jessica H; Carone, Marco; Silbergeld, Ellen K

2010-03-25

Models of between-farm transmission of pathogens have identified service vehicles and social groups as risk factors mediating the spread of infection. Because of high levels of economic organization in much of the poultry industry, we examined the importance of company affiliation, as distinct from social contacts, in a model of the potential spread of avian influenza among broiler poultry farms in a poultry-dense region in the United States. The contribution of company affiliation to risk of between-farm disease transmission has not been previously studied. We obtained data on the nature and frequency of business and social contacts through a national survey of broiler poultry growers in the United States. Daily rates of contact were estimated using Monte Carlo analysis. Stochastic modeling techniques were used to estimate the exposure risk posed by a single infectious farm to other farms in the region and relative risk of exposure for farms under different scenarios. The mean daily rate of vehicular contact was 0.82 vehicles/day. The magnitude of exposure risk ranged from company affiliation, with farms in the same company group as the index farm facing as much as a 5-fold increase in risk compared to farms contracted with different companies. Employment of part-time workers contributed to significant increases in risk in most scenarios, notably for farms who hired day-laborers. Social visits were significantly less important in determining risk. Biosecurity interventions should be based on information on industry structure and company affiliation, and include part-time workers as potentially unrecognized sources of viral transmission. Modeling efforts to understand pathogen transmission in the context of industrial food animal production should consider company affiliation in addition to geospatial factors and pathogen characteristics. Restriction of social contacts among farmers may be less useful in reducing between-farm transmission.

2017-01-01

Starting this summer, Fermilab will host a key experiment dedicated to the search for signals of new physics: The Fermilab Muon g-2 Experiment. Its aim is to precisely measure the anomalous magnetic moment of the muon. In full operation, in order to avoid contamination, the newly born secondary beam is injected into a 505 m long Delivery Ring (DR) wherein it makes several revolutions before being sent to the experiment. Part of the commissioning scenario will execute a running mode wherein the passage from the DR will be skipped. With the aid of numerical simulations, we provide estimates of the expected performance.

Fermilab is investigating the use of PC's for HEP computing. As a first step we have built a full offline environment under Linux on a set of Pentium (P5) and Pentium Pro (P6) machines (the ''PC Farm''). The Pythia simulation has been ported to run serially and in parallel (using CPS) on the PC Farm. Fermilab software products and CDF offline packages have also been ported to Linux. Run 1 CDF data has been analyzed on both Linux and SGI (Irix) with essentially identical results. The performance of the system is compared to results with commercial UNIX systems

Fermilab Recycler Ring: Technical design report. Revision 1.1

International Nuclear Information System (INIS)

Jackson, G.

1996-07-01

This report describes the technical design of the Fermilab Recycler Ring. The purpose of the Recycler is to augment the luminosity increase anticipated from the implementation of the Fermi III upgrade project, which has as its main component the Fermilab Main Injector construction project. The Recycler is a fixed 8 GeV kinetic energy storage ring. It is located in the Main Injector tunnel directly above the Main Injector beamline, near the ceiling. The construction schedule calls for the installation of the Recycler ring before the installation shutdown of the Main Injector. This aggressive construction schedule is made possible by the exclusive use of permanent magnets in the ring lattice, removing the need for expensive conventional iron/copper magnet construction along with the related power supplies, cooling water system, and electrical safety systems. The location, operating energy, and mode of construction are chosen to minimize operational impacts on both Fermilab's ongoing High Energy Physics program and the Main Injector construction project

2015-03-12

Since 1984 Fermilab has been hosting a two-month summer training program for selected undergraduate and graduate Italian students in physics and engineering. Building on the traditional close collaboration between the Italian National Institute of Nuclear Physics (INFN) and Fermilab, the program is supported by INFN, by the DOE and by the Scuola Superiore di Sant`Anna of Pisa (SSSA), and is run by the Cultural Association of Italians at Fermilab (CAIF). This year the University of Pisa has qualified it as a “University of Pisa Summer School”, and will grant successful students with European Supplementary Credits. Physics students join the Fermilab HEP research groups, while engineers join the Particle Physics, Accelerator, Technical, and Computing Divisions. Some students have also been sent to other U.S. laboratories and universities for special trainings. The programs cover topics of great interest for science and for social applications in general, like advanced computing, distributed data analysis, nanoelectronics, particle detectors for earth and space experiments, high precision mechanics, applied superconductivity. In the years, over 350 students have been trained and are now employed in the most diverse fields in Italy, Europe, and the U.S. In addition, the existing Laurea Program in Fermilab Technical Division was extended to the whole laboratory, with presently two students in Master’s thesis programs on neutrino physics and detectors in the Neutrino Division. And finally, a joint venture with the Italian Scientists and Scholars North-America Foundation (ISSNAF) provided this year 4 professional engineers free of charge for Fermilab. More details on all of the above can be found below.

Integrable RCS as a Proposed Replacement for Fermilab Booster

Energy Technology Data Exchange (ETDEWEB)

Eldred, Jeffrey [Fermilab; Valishev, Alexander [Fermilab

2017-03-07

Integrable optics is an innovation in particle accelerator design that potentially enables a greater betatron tune spread and damps collective instabilities. An integrable rapid-cycling synchrotron (RCS) would be an effective replacement for the Fermilab Booster, as part of a plan to reach multi-MW beam power at 120 GeV for the Fermilab high-energy neutrino program. We provide an example integrable lattice with features of a modern RCS - dispersion-free drifts, low momentum compaction factor, superperiodicity, chromaticity correction, bounded beta functions, and separate-function magnets.

The article reports on achievements of various people, staff changes and position opportunities within the CERN organization and contains news updates on upcoming or past events. The detail of the LEP electron-positron storage ring project continues to be studied so as to optimize the machine parameters from the point of view of performance and of cost. The Weizmann Institute of Science in Israel has established the Albert Einstein Centre for Theoretical Physics with an endowment fund from the Federal Republic of Germany. Aimed at strengthening the ties and exchange of ideas between theoretical physicists from Israel and abroad the Centre plans to host postdoctoral fellows and visiting senior theorists. After several years of planning, a major upgrade has now been decided for the central computer system at SLAC, presently based on IBM 360/91 and 370/168 machines. Fermilab has established an Industrial Affiliate Programme designed to foster improved communication between the basic research carried out at Fermilab and in industry. The affiliate programme will acquaint the Industrial Associates with work at Fermilab through special seminars and publications. A further indication of the commitment of Stanford to the linear collider project (SLC) is the organization of a meeting on 25-27 March to inform the US high energy physics community of the progress of the project, to promote involvement in machine design and to indicate the experimental possibilities it will provide. Although now firmly established as part of particle physics dogma, the quark model has had a somewhat chequered history. Before the discovery of the omega minus baryon in 1964, it had a particularly rough time. In an invited talk at last year's Baryon Conference in Toronto, George Zweig of Caltech reminisced about the early years of the model

Prospects for antiproton experiments at Fermilab

International Nuclear Information System (INIS)

Kaplan, Daniel M.

2012-01-01

Fermilab operates the world’s most intense antiproton source. Newly proposed experiments can use those antiprotons either parasitically during Tevatron Collider running or after the end of the Tevatron Collider program. For example, the annihilation of 5 to 8 GeV antiprotons is expected to yield world-leading sensitivities to hyperon rare decays and CP violation. It could also provide the world’s most intense source of tagged D 0 mesons, and thus the best near-term opportunity to study charm mixing and, via CP violation, to search for new physics. Other measurements that could be made include properties of the X(3872) and the charmonium system. An experiment using a Penning trap and an atom interferometer could make the world’s most precise measurement of the gravitational force on antimatter. These and other potential measurements using antiprotons offer a great opportunity for a broad and exciting physics program at Fermilab in the post-Tevatron era.

Fermilab turns up the heat on electron cooling

CERN Document Server

Riesselmann, K

2002-01-01

A technique that was first proposed by Gersh Budker in 1966 is being injected with new life by a team of physicists at Fermilab in the US. Working on an ambitious electron-cooling project, the team set a new world record for DC beam power, they maintained a continuous 3.5 MeV electron beam with a current of more than 500 mA for up to 8 h with only short interruptions. They use an electron beam to cool antiprotons inside Fermilab's 3 km Recycler antiproton storage ring and boost the luminosity of the laboratory's Tevatron collider. When the electron-cooling system is complete, electrons and antiprotons will travel side by side in the Recycler.

Lending behavior of multinational bank affiliates

Directory of Open Access Journals (Sweden)

Alexis Derviz

2011-03-01

Full Text Available We study the parent influence on lending by affiliates of a multinational bank. In the proposed theoretical model, local lending is influenced by shareholder-affiliate manager delegation and precautionary motives. The outcome is either contagion (the loan volume in the affiliate follows the direction of the parent bank country shock or performance-based reallocation of funds (substitution, depending on the degree of manager delegation in the affiliate and the liquidity-sensitivity in theparent bank. Empirical investigation, deliberately conducted on a sample not covering the latest financial crisis, shows that also in “normal” times, multinational banks that are likely to delegate lending decisions or be more liquidity-sensitive are more inclined towards contagionist behavior.

Gaps in affiliation indexing in Scopus and PubMed.

Science.gov (United States)

Schmidt, Cynthia M; Cox, Roxanne; Fial, Alissa V; Hartman, Teresa L; Magee, Martha L

2016-04-01

The authors sought to determine whether unexpected gaps existed in Scopus's author affiliation indexing of publications written by the University of Nebraska Medical Center or Nebraska Medicine (UNMC/NM) authors during 2014. First, we compared Scopus affiliation identifier search results to PubMed affiliation keyword search results. Then, we searched Scopus using affiliation keywords (UNMC, etc.) and compared the results to PubMed affiliation keyword and Scopus affiliation identifier searches. We found that Scopus's records for approximately 7% of UNMC/NM authors' publications lacked appropriate UNMC/NM author affiliation identifiers, and many journals' publishers were supplying incomplete author affiliation information to PubMed. Institutions relying on Scopus to track their impact should determine whether Scopus's affiliation identifiers will, in fact, identify all articles published by their authors and investigators.

Fermilab Muon Campus g-2 Cryogenic Distribution Remote Control System

Energy Technology Data Exchange (ETDEWEB)

Pei, L.; Theilacker, J.; Klebaner, A.; Soyars, W.; Bossert, R.

2015-11-05

The Muon Campus (MC) is able to measure Muon g-2 with high precision and comparing its value to the theoretical prediction. The MC has four 300 KW screw compressors and four liquid helium refrigerators. The centerpiece of the Muon g-2 experiment at Fermilab is a large, 50-foot-diameter superconducting muon storage ring. This one-of-a-kind ring, made of steel, aluminum and superconducting wire, was built for the previous g-2 experiment at Brookhaven. Due to each subsystem has to be far away from each other and be placed in the distant location, therefore, Siemens Process Control System PCS7-400, Automation Direct DL205 & DL05 PLC, Synoptic and Fermilab ACNET HMI are the ideal choices as the MC g-2 cryogenic distribution real-time and on-Line remote control system. This paper presents a method which has been successfully used by many Fermilab distribution cryogenic real-time and On-Line remote control systems.

It is based on six commercial 150 kW Power Energy Industries power supply modules and the following in-house modules: six 720 Hz filters, two 15 kA/1kV dc solid-state dump switch, and a 3 MJ/30 kA/1 kV dc dump resistor. Additional inhouse electronic components were designed and built to provide precise current regulation and distribution of current and current rate of change. An industrial-type Programmable Logic Controller system was used to provide equipment interlocks and monitoring. This paper summarizes studies on the influence of characteristics of this new power system--such as ripple current--on the performance of High Field Superconducting magnets.

Fermilab has adopted the Source Evaluation Board (SEB) method for procuring certain major technical components of the Fermilab Main Injector. The SEB procedure is designed to ensure the efficient and effective expenditure of Government funds at the same time that it optimizes the opportunity for attainment of project objectives. A qualitative trade-off is allowed between price and technical factors. The process involves a large amount of work and is only justified for a very limited number of procurements. Fermilab has gained experience with the SEB process in awarding subcontracts for major subassemblies of the Fermilab Main Injector dipoles

Fermilab's SC Accelerator Magnet Program for Future U.S. HEP Facilities

International Nuclear Information System (INIS)

Lamm, Michael; Zlobin, Alexander

2010-01-01

The invention of SC accelerator magnets in the 1970s opened wide the possibilities for advancing the energy frontier of particle accelerators, while limiting the machine circumference and reducing their energy consumption. The successful development of SC accelerator magnets based on NbTi superconductor have made possible a proton-antiproton collider (Tevatron) at Fermilab, an electron-proton collider (HERA) at DESY, a relativistic heavy ion collider (RHIC) at BNL and recently a proton-proton collider (LHC) at CERN. Further technological innovations and inventions are required as the US HEP looks forward towards the post-LHC energy or/and intensity frontiers. A strong, goal oriented national SC accelerator magnet program must take on this challenge to provide a strong base for the future of HEP in the U.S. The results and experience obtained by Fermilab during the past 30 years will allow us to play a leadership role in the SC accelerator magnet development in the U.S., in particular, focusing on magnets for a Muon Collider/Neutrino Factory (1)-(2). In this paper, we summarize the required Muon Collider magnet needs and challenges, summarize the technology advances in the Fermilab accelerator magnet development over the past few years, and present and discuss our vision and long-term plans for these Fermilab-supported accelerator initiatives.

Etude Experimentale du Photo-Injecteur de Fermilab

Energy Technology Data Exchange (ETDEWEB)

Carneiro, Jean-Paul [Orsay

2001-01-01

TESLA (TeV Superconducting Linear Accelerator) is an international collaboration which is studying the feasibility of an $e^+e^-$ collider of energy 0.8 TeV in the center of mass. One of the first goals of this collaboration was to construct a prototype linear accelerator at the DESY Laboratory in Hamburg, the TESLA Test Facility (TTF), in order to establish the technical basis for the collider. Two injectors were developed for TTF: a thermionic injector (developed by LAL-Orsay, IPN-Orsay, and CEA-Saclay) and a photo-injector (developed by Fermilab). The thermionic injector was used from February 1997 to October 1998, and then it was replaced by the photo-injector, which was first operated in December 1998. Another photo-injector, identical to the one delivered to TTF, was installed at Fermilab in the $A{\\emptyset}$ Building. The first beam from the latter was produced on 3 March 1999. The photo-injector consists of an RF gun, followed by a superconducting cavity. The RF gun is a 1.625-cell copper cavity with a resonant frequency of 1.3 GHz. The gun contains a cesium telluride ($C_{s_2}$Te) photo-cathode, which is illuminated by UV pulses from a Nd:YLF laser. The system can produce trains of 800 bunches of photo-electrons of charge 8 nC per bunch with spacing between bunches of 1$\\mu$s and 10 Hz repetition rate. Upon emerging from the RF gun, the beam energy is 4 to 5 MeV; the beam is then rapidly accelerated by the superconducting cavity to an energy of 17 to 20 MeV. Finally, a magnetic chicane, consisting of 4 dipoles, produces longitudinal compression of the electron bunches. This thesis describes the installation of the photo-injector at Fermilab and presents the experimentally-measured characteristics of the injector. The principal measurements were quantum eciency, dark current, transverse emittance, and bunch length. The conclusion from these studies is that the quality of the photo-injector beam fullls the design goals. The photo-injector at Fermilab is

CDF, the Collider Detector at Fermilab, is a collaboration of almost 180 physicists from ten US universities (University of Chicago, Brandeis University, Harvard University, University of Illinois, University of Pennsylvania, Purdue University, Rockefeller University, Rutgers University, Texas A and M University, and University of Wisconsin), three US DOE supported national laboratories (Fermilab, Argonne National Laboratory, and Lawrence Berkeley Laboratory), Italy (Frascati National Laboratory and University of Pisa), and Japan (KEK National Laboratory and University of Tsukuba). The primary physics goal for CDF is to study the general features of proton-antiproton collisions at 2 TeV center-of-mass energy. On general grounds, we expect that parton subenergies in the range 50 to 500 GeV will provide the most interesting physics at this energy. Work at the present CERN Collider has already demonstrated the richness of the 100 GeV scale in parton subenergies. 7 refs., 14 figs

Seismic studies for Fermilab future collider projects

International Nuclear Information System (INIS)

Lauh, J.; Shiltsev, V.

1997-11-01

Ground motion can cause significant beam emittance growth and orbit oscillations in large hadron colliders due to a vibration of numerous focusing magnets. Larger accelerator ring circumference leads to smaller revolution frequency and, e.g. for the Fermilab Very Large Hadron Collider(VLHC) 50-150 Hz vibrations are of particular interest as they are resonant with the beam betatron frequency. Seismic measurements at an existing large accelerator under operation can help to estimate the vibrations generated by the technical systems in future machines. Comparison of noisy and quiet microseismic conditions might be useful for proper choice of technical solutions for future colliders. This article presents results of wide-band seismic measurements at the Fermilab site, namely, in the tunnel of the Tevatron and on the surface nearby, and in two deep tunnels in the Illinois dolomite which is though to be a possible geological environment of the future accelerators

Today vertically integrated circuits, (a.k.a. 3D integrated circuits) is a popular topic in many trade journals. The many advantages of these circuits have been described such as higher speed due to shorter trace lenghts, the ability to reduce cross talk by placing analog and digital circuits on different levels, higher circuit density without the going to smaller feature sizes, lower interconnect capacitance leading to lower power, reduced chip size, and different processing for the various layers to optimize performance. There are some added advantages specifically for MAPS (Monolithic Active Pixel Sensors) in High Energy Physics: four side buttable pixel arrays, 100% diode fill factor, the ability to move PMOS transistors out of the diode sensing layer, and a increase in channel density. Fermilab began investigating 3D circuits in 2006. Many different bonding processes have been described for fabricating 3D circuits [1]. Fermilab has used three different processes to fabricate several circuits for specific applications in High Energy Physics and X-ray imaging. This paper covers some of the early 3D work at Fermilab and then moves to more recent activities. The major processes we have used are discussed and some of the problems encountered are described. An overview of pertinent 3D circuit designs is presented along with test results thus far.

Spin Tracking of Polarized Protons in the Main Injector at Fermilab

2016-07-01

The Main Injector (MI) at Fermilab currently produces high-intensity beams of protons at energies of 120 GeV for a variety of physics experiments. Acceleration of polarized protons in the MI would provide opportunities for a rich spin physics program at Fermilab. To achieve polarized proton beams in the Fermilab accelerator complex, shown in Fig.1.1, detailed spin tracking simulations with realistic parameters based on the existing facility are required. This report presents studies at the MI using a single 4-twist Si-berian snake to determine the depolarizing spin resonances for the relevant synchrotrons. Results will be presented first for a perfect MI lattice, followed by a lattice that includes the real MI imperfections, such as the measured magnet field errors and quadrupole misalignments. The tolerances of each of these factors in maintaining polariza-tion in the Main Injector will be discussed.

Several hundred physicists attended a special Fermilab 'All Experimenter's Meeting' on November 20 to hear Director John Peoples call for new Tevatron Collider proposals for the years 2000-2005, when the new Main Injector will be complete. At the Tevatron proton-antiproton collider, the CDF and DO experiments are currently completing improvements for Run II to use the Tevatron when the Main Injector is complete later in this decade. New proposals would be aimed at a Collider Run III to follow these CDF and DO efforts

Preliminary report on the utilization of the Fermilab site for a future accelerator

International Nuclear Information System (INIS)

1996-10-01

This report is a preliminary assessment of the utility of the Fermilab site for future accelerator projects. It responds to a request from the Director to evaluate how the Fermilab site and infrastructure may be relevant to future accelerator projects in the U.S. The SSC experience suggests that any major new project will have to be based on the existing infrastructure at one of the National Laboratories. This work presents only the technical issues and the benefits of the Fermilab site and infrastructure. The projects treated are: (1) A really large hadron collider based on the ''Pipetron'' vision of low-field (2 Tesla) magnets in a small diameter tunnel. Another option, not treated in detail, is a hadron collider using high field magnets. (2) Muon Colliders with 250 GeV and 2 TeV per beam. (3) A linear electron collider with 250 to 500 GeV per beam. The infrastructure of the state of Illinois - geology, hydrology, power and surface water- seems remarkably well suited to any of these projects. The geology of most of Illinois, including Fermilab, contains a dolomite layer that: has low seismic activity, is at an appropriate depth to provide radiation protection, is essentially impervious to water movement and thus satisfies hydrology requirements. There is adequate electrical power - both locally and statewide. We first give brief overviews of the Fermilab and Illinois infrastructure - geology, hydrology, power, and water - and then a summary of each project. On the basis of what we have learned, we feel that Fermilab must be considered seriously as a site for any of these projects. Beyond this point, however site-specific plans will need to be developed for each of the projects

Sex differences in cortisol's regulation of affiliative behavior.

A contribution to a special issue on Hormones and Human Competition. A stress perspective is used to illuminate how competitive defeat and victory shape biology and behavior. We report a field study examining how change in cortisol following perceived defeat (vs. victory) in a competition-in this case, a dog agility competition-relates to affiliative behavior. Following competition, we measured cortisol change and the extent to which dog handlers directed affiliative behaviors toward their dogs. We found striking sex differences in affiliation. First, men were more affiliative toward their dogs after victory, whereas women were more affiliative after defeat. Second, the greater a female competitor's increase in cortisol, the more time she spent affiliating with her dog, whereas for men, the pattern was the exact opposite: the greater a male competitor's increase in cortisol, the less time he spent affiliating with his dog. This pattern suggests that, in the wake of competition, men and women's affiliative behavior may serve different functions-shared celebration for men; shared consolation for women. These sex differences show not only that men and women react very differently to victory and defeat, but also that equivalent changes in cortisol across the sexes are associated with strikingly different behavioral consequences for men and women.

A development plan for the Fermilab proton source

International Nuclear Information System (INIS)

Holmes, S. D.

1997-01-01

The present Fermilab Proton Source is composed of a 750 KV ion source, a 400 MeV Linac, and an 8 GeV Booster synchrotron. This facility currently provides proton beams at intensities up to 5 x 10 10 protons/bunch for injection into the Main Ring in support of the current Tevatron fixed target run. Following completion of the Main Injector project in 1999, the Proton Source is expected to provide protons to the Main Injector at an intensity of 6 x 10 10 protons/bunch as required to meet established performance goals for Tevatron Collider Run II. With the advent of the Main Injector the demand for protons in support of a diverse physics research program at Fermilab will grow. This is because the Main Injector creates a new capability for simultaneous operation of the collider and fixed target programs at 120 GeV. It has also been recently appreciated that a physics program based on the utilization of unallocated 8 GeV Booster cycles is potentially very attractive. A variety of experiments are either approved or under consideration including the Neutrinos at the Main Injector (NUMI) project, Kaons at the Main Injector (KAMI), and an rf separated K + beam for CPT tests, all utilizing 120 GeV protons, and a low energy neutrino (MiniBooNe) or muon program based on 8 GeV protons from the Booster. In addition significant effort is now being invested in defining paths to a factor of five improvement in Tevatron collider luminosity beyond those expected in Run II and in understanding the possible future siting of either a very large hadron collider or a modest energy ''First Muon Collider'' (FMC) at Fermilab. Support for these varied activities is beyond the capabilities of the current Proton Source--in the case of the FMC by about a factor of ten as measured in delivered protons per second. The purpose of this document is to describe a possible evolution of the Fermilab Proton Source over the next ten years. The goal is to outline a staged plan, with significant

Operating experience with the Fermilab 500-GeV accelerator

International Nuclear Information System (INIS)

Urban, G.S.; Gannon, J.C.

1977-01-01

The Fermilab accelerator has been operating for more than four years. It has been improved so that it is now capable of operating at an energy of 500 GeV and an intensity in excess of 2.0 x 10 13 protons per pulse. The accelerator is manned on a 24 hour a day basis by an operating team of five persons. This is possible in part, because almost all of the hardware systems have status monitoring and control through an advanced computer control system. A discussion is given of the operation of the accelerator with emphasis on person to machine interface, operator training techniques used at Fermilab, and the keeping of records and reliability information

Control system for Fermilab's low temperature upgrade

International Nuclear Information System (INIS)

Norris, B.L.

1996-09-01

Fermilab recently upgraded the Tevatron Cryogenic Systems to allow for lower temperature operation. This Lower Temperature Upgrade grew out of a desire to increase the Colliding Beam Physics energy from 900 GeV to 1000 GeV. A key element in achieving this goal is the new cryogenic control system designed at Fermilab and installed in 24 satellite refrigerators and 8 compressor buildings. The cryogenic improvements and addition hardware like cold compressors exceeded the capability of the original distributed controls package. The new distributed controls package uses a Multibus II platform and Intel's 80386 microprocessor. Token Ring is used as the link to the systems 6 primary crate locations with Arcnet used as the connection to the systems numerous I/O crates. I/0 capabilities are double the capabilities of the original system. Software has also been upgraded with the introduction of more flexible control loop strategies and Finite State Machines used for automatic sequential control, like quench recovery or cold compressor pump down

In this new survey, patients ranked religious affiliation low in importance when choosing among hospitals. However, hospitals of a particular religious affiliation were more likely to be recalled, preferred, and selected by people of the same religious affiliation. Furthermore, on quality-of-care measures, religious affiliation influenced hospital evaluations.

Mediation of Family Alcoholism Risk by Religious Affiliation Types*

Science.gov (United States)

Haber, Jon Randolph; Jacob, Theodore

2009-01-01

Objective: Religious affiliation is inversely associated with alcohol dependence (AD). Our previous findings indicated that when a religious affiliation differentiated itself from cultural norms, then high-risk adolescents (those having parents with alcoholism history) raised with these affiliations exhibited fewer AD symptoms compared with adolescents of other religious affiliations and nonreligious adolescents. The first of two studies reported here provides a needed replication of our previous findings for childhood religious affiliation using a different sample, and the second study extends examination to current religious affiliation. Method: A national sample of male and female adolescents/young adults (N = 1,329; mean age = 19.6 years) was selected who were the offspring of members of the Vietnam Era Twin Registry. Parental alcoholism, religious affiliation types, and their interactions were examined as predictors of offspring AD symptoms. Results: (1) Offspring reared with a differentiating religious affiliation during childhood exhibited significantly fewer AD symptoms as young adults; (2) offspring with current differentiating religious affiliation also exhibited fewer AD symptoms; this main effect was not weakened by adding other measures of religiousness to the model; (3) differentiating religious affiliation was correlated with both family alcoholism risk and offspring outcome, and removed the association between family alcoholism risk and offspring outcome, thus indicating that differentiating religious affiliation was at least a partial mediator of the association between family AD history risk and offspring AD outcome. Conclusions: Current results indicate that religious differentiation is an inverse mediator of alcoholism risk for offspring with or without parental AD history and regardless of the influence of other religion variables. Results replicated our previous report on religious upbringing between ages 6 and 13 years and indicated an even

Overview of the next generation of Fermilab collider software

International Nuclear Information System (INIS)

Hendricks, B.; Joshel, R.

1992-01-01

Fermilab is entering an era of operating a more complex collider facility. In addition, new operator workstations are available that have increased capabilities. The task of providing updated software in this new environment precipitated a project called Colliding Beam Software (CBS). It was soon evident that a new approach was needed for developing console software. Hence CBS, although a common acronym, is too narrow a description. A new generation of the application program subroutine library has been created to enhance the existing programming environment with a set of value added tools. Several key Collider applications were written that exploit CBS tools. This paper will discuss the new tools and the underlying change in methodology in application program development for accelerator control at Fermilab. (author)

The stripline BPMs are estimated to have an average signal output of between -110 dBm and -80 dBm, with an estimated peak output of -70 dBm. The external resonant circuit is tuned to the SY machine frequency of 53.10348 MHz. Both the digitizer and transition boards have variable gain in order to accommodate the large dynamic range and irregularity of the resonant extraction spill. These BPMs will aid in auto-tuning of the SY beamline as well as enabling operators to monitor beam position through the spill.

The Fermilab Antiproton Source is the world's most intense source of antimatter. With the Tevatron program now behind us, this unique facility can help make the case for Fermilab's continued accelerator operations. The Antiproton Source can be used for unique, dedicated antimatter studies, including medium-energy {bar p}-annihilation experiments. We propose to assemble a powerful, yet cost-effective, solenoidal magnetic spectrometer for antiproton-annihilation events, and to use it at the Fermilab Antiproton Accumulator to measure the charm production cross section, study rare hyperon decays, search for hyperon CP asymmetry, precisely measure the properties of several charmonium and nearby states, and make the first measurements of the Drell-Yan continuum in medium-energy antiproton annihilation. Should the charm production cross section be as large as some have proposed, we will also be able to measure D{sup 0}-{bar D}{sup 0} mixing with high precision and discover (or sensitively limit) charm CP violation. The observation of charm or hyperon CP violation would be evidence for physics beyond the Standard Model, with possible implications for the origin of the baryon asymmetry of the universe - the question of what happened to all the antimatter that must have been produced in the Big Bang. The experiment will be carried out by an international collaboration and will require some four years of running time. As possibly the sole hadron experiment in progress at Fermilab during that time, it will play an important role in maintaining a broad particle physics program at Fermilab and in the U.S. It will thus help us to continue attracting creative and capable young people into science and technology, and introducing them to the important technologies of accelerators, detectors, and data acquisition and analysis - key roles in society that accelerator-based particle physics has historically played.

The Cryomodule Test Facility (CMTF) is able to provide the necessary test bed for measuring the performance of Superconducting Radio Frequency (SRF) cavities in a cryomodule (CM). The CMTF have seven 300 KW screw compressors, two liquid helium refrigerators, and two Cryomodule Test Stands (CMTS). CMTS1 is designed for 1.3 GHz cryomodule operating in a pulsed mode (PM) and CMTS2 is for cryomodule operating in Half-Wave (HW) and Continuous Wave (CW) mode. Based on the design requirement, each subsystem has to be far away from each other and be placed in distant locations. Therefore choosing Siemens Process Control System 7-400, DL205 PLC, Synoptic and Fermilab ACNET are the ideal choices for CMTF cryogenic distribution real-time remote control system. This paper presents a method which has been successfully used by many Fermilab distribution cryogenic real-time remote control systems.

Status of the Fermilab Energy Doubler/Saver project

Energy Technology Data Exchange (ETDEWEB)

1977-01-01

The possibility of building a ring of superconducting magnets was considered very early in the design of the Fermilab main accelerator. It was concluded that the technology of superconducting magnets was not at that time, sufficiently advanced. Therefore, the main ring was designed and built with conventional magnets. However, space was left in the main-ring tunnel for a future ring of superconducting magnets. The Energy Doubler/Saver (ED/S) was initiated in 1972 as a project to build a ring of superconducting magnets with the objective of dramatically increasing the research potential of the Fermilab accelerators. This was to be accomplished at a moderate cost and in such a manner as to make possible a significant saving of electrical energy. A description is given of the evolution of this program as well as give a status report of the Ed/S research and development program.

Tunneling beyond the Fermilab site

International Nuclear Information System (INIS)

Baker, S.; Elwyn, A.; Lach, J.; Read, A.

1983-01-01

An accelerator that crosses the Fermilab site boundary must have a minimum effect on the surrounding environment and the people residing in the area. Unobstructed public access should be allowed above the ring except in relatively few areas such as the injection, dump, and experimental regions. The accelerator should be a benign and unobtrusive neighbor not only when it is completed but also in the construction period. For these reasons underground tunneling for all or most of the ring seems attractive. In this note we look into some questions raised by tunneling beyond the Fermilab site. Most of our discussion is of general applicability. However, we will use as examples two specific ring configurations. The examples have not been optimized from the point of view of physics output or accelerator technology but are just specific examples which allow us to study questions of tunneling. One is a ring of 5 km radius (5 TeV) tangent to the Tevatron and entirely east of the Fox River and fed by a beam from the Tevatron which crosses under the river. We assume that each of these machines will have 100 beam fills per year and we scale the maximum intensities with the accelerator radii. Thus we assume that there will be 1.0 E14 protons in each beam of the 20 TeV machine and 2.5 E13 for the 5 TeV machine

Energy Doubler/Saver at Fermilab: a status report

International Nuclear Information System (INIS)

Fowler, W.B.

1977-01-01

Guided, as in the past, by close attention to the developing theoretical and experimental evidence for new phenomena (for example, the discoveries of weak neutral currents, charm, J/psi and the Upsilon) Fermilab has devoted considerable effort to pushing on to higher energies. This seems particularly appropriate since other phenomena is suggested, such as intermediate vector bosons (W + and Z 0 ) etc. The TeV Project at Fermilab pursues both increases in the available energy via doubling the energy of the present accelerator as a fixed target, high intensity proton synchrotron and via colliding beams. These ways are complementary to one another. High energy physics with fixed targets cannot match the energy available in the center of mass system that can be achieved in colliding beams, whereas physics with colliding beams cannot match the intensities or the variety of bombarding particles that can be achieved with fixed targets. Some of the aspects of each technique are given

Fermilab Plan with a High Intensity Proton Source

CERN Multimedia

CERN. Geneva

2008-01-01

Fermilab, the US’s primary laboratory for particle physics, proposes a plan to maintain leadership for the laboratory and U.S. particle physics in the quest to discover the fundamental nature of the physical universe in the decades ahead. Discoveries of the physics of the Quantum Universe would come from powerful next generation particle accelerators. Fermilab’s Tevatron, currently the world’s most powerful particle accelerator, will shut down by the end of this decade after the LHC at CERN begins operations. At the LHC, U.S. physicists will join scientists from around the world in the exploration of the physics of the Terascale. To follow the LHC, physicists propose the International Linear Collider, a globally funded and operated accelerator to build on LHC results and illuminate Terascale science. Fermilab will work to host the proposed ILC in the U.S. as soon as possible, maintaining the nation’s historic leadership of frontier particle physics. Should events postpone the start of the ILC, Ferm...

Electronic Information Systems Use in Residential Care Facilities: The Differential Effect of Ownership Status and Chain Affiliation.

Science.gov (United States)

Davis, Jullet A; Zakoscielna, Karolina; Jacobs, Lindsey

2016-03-01

The use of electronic information systems (EISs) including electronic health records continues to increase in all sectors of the health care industry. Research shows that EISs may be useful for improving care delivery and decreasing medical errors. The purpose of this project is twofold: First, we describe the prevalence of EIS use among residential care facilities (RCFs), and second, we explore utilization differences by ownership status and chain affiliation. We anticipate that RCFs that are non-profit and non-chain will use more EIS than other categories of RCFs. Data for this project come from the 2010 National Survey of Residential Care Facilities. The sample consists of 2,300 facilities. Overall use of EIS was greatest among RCFs that are non-profit and chain-affiliated. Conversely, the use was lowest among for-profit RCFs that were also non-chain affiliated. This may suggest that these facilities lack the necessary resources or motivation to invest in information systems. © The Author(s) 2014.

Attitudes towards active voluntary euthanasia (AVE) and physician-assisted suicide (PAS) among 1,238 doctors on the medical register of New South Wales varied significantly with self-identified religious affiliation. More doctors without formal religious affiliation ('non-theists') were sympathetic to AVE, and acknowledged that they had practised AVE, than were doctors who gave any religious affiliation ('theists'). Of those identifying with a religion, those who reported a Protestant affiliation were intermediate in their attitudes and practices between the agnostic/atheist and the Catholic groups. Catholics recorded attitudes most opposed to AVE, but even so, 18 per cent of Catholic medical respondents who had been so requested, recorded that they had taken active steps to bring about the death of patients.

Fermilab is preparing to mount a variety of new experiments at the Intensity Frontier, all of which require infrastructure software including a framework, an event data model, persistency, run-time configuration, management of singleton-like entities such as the geometry and conditions data, integration with Geant4 (G4), build and release management, and integration with GRID based work-flow management systems. In order to maximize the return on both past and future effort invested in supporting CMS, the Fermilab Computing Division (CD) has extracted the core of the CMS framework plus many parts of its associated infrastructure software; CD is supporting this infrastructure for use by the new Intensity Frontier experiments. This talk will present the plans for and status of this infrastructure software including points of view from both the developers and the physicist-clients working on the Mu2e experiment.

A facility for accelerator research and education at Fermilab

International Nuclear Information System (INIS)

Church, Mike; Nagaitsev, Sergei

2009-01-01

Fermilab is currently constructing the 'SRF Test Accelerator at the New Muon Lab' (NML). NML consists of a photo-emitted RF electron gun, followed by a bunch compressor, low energy test beamlines, SCRF accelerating structures, and high energy test beamlines. The initial primary purpose of NML will be to test superconducting RF accelerating modules for the ILC and for Fermilab's 'Project X' - a proposal for a high intensity proton source. The unique capability of NML will be to test these modules under conditions of high intensity electron beams with ILC-like beam parameters. In addition NML incorporates a photoinjector which offers significant tunability and especially the possibility to generate a bright electron beam with brightness comparable to state-of-the-art accelerators. This opens the exciting possibility of also using NML for fundamental beams research and tests of new concepts in beam manipulations and acceleration, instrumentation, and the applications of beams.

It is intended to supplement the variety of detectors known in the vernacular as SWICS that are used to obtain profiles for beam tuning. The new detector, described in this report, operates in the limited proportional mode and allows experimenters to use a standard, lab supported device for associating trajectories of individual beam particles with events triggering their own experiment's apparatus. A completed triple plane module is shown

The current generation of UNIX farms at Fermilab are rapidly approaching the end of their useful life. The workstations were purchased during the years 1991-1992 and represented the most cost-effective computing available at that time. Acquisition of new workstations is being made to upgrade the UNIX farms for the purpose of providing large amounts of computing for reconstruction of data being collected at the 1996-1997 fixed-target run, as well as to provide simulation computing for CMS, the Auger project, accelerator calculations and other projects that require massive amounts of CPU. 4 refs., 1 fig., 2 tabs

Big Data over a 100 G network at Fermilab

Garzoglio, Gabriele; Mhashilkar, Parag; Kim, Hyunwoo; Dykstra, Dave; Slyz, Marko

2014-01-01

As the need for Big Data in science becomes ever more relevant, networks around the world are upgrading their infrastructure to support high-speed interconnections. To support its mission, the high-energy physics community as a pioneer in Big Data has always been relying on the Fermi National Accelerator Laboratory to be at the forefront of storage and data movement. This need was reiterated in recent years with the data-taking rate of the major LHC experiments reaching tens of petabytes per year. At Fermilab, this resulted regularly in peaks of data movement on the Wide area network (WAN) in and out of the laboratory of about 30 Gbit/s and on the Local area network (LAN) between storage and computational farms of 160 Gbit/s. To address these ever increasing needs, as of this year Fermilab is connected to the Energy Sciences Network (ESnet) through a 100 Gb/s link. To understand the optimal system-and application-level configuration to interface computational systems with the new highspeed interconnect, Fermilab has deployed a Network Research and Development facility connected to the ESnet 100 G Testbed. For the past two years, the High Throughput Data Program (HTDP) has been using the Testbed to identify gaps in data movement middleware [5] when transferring data at these high-speeds. The program has published evaluations of technologies typically used in High Energy Physics, such as GridFTP [4], XrootD [9], and Squid [8]. This work presents the new R and D facility and the continuation of the evaluation program.

Nash, T.; Areti, H.; Atac, R.

1986-09-01

The Advanced Computer Program at Fermilab has developed a multiprocessor system which is easy to use and uniquely cost effective for many high energy physics problems. The system is based on single board computers which cost under $2000 each to build including 2 Mbytes of on board memory. These standard VME modules each run experiment reconstruction code in Fortran at speeds approaching that of a VAX 11/780. Two versions have been developed: one uses Motorola's 68020 32 bit microprocessor, the other runs with AT and T's 32100. both include the corresponding floating point coprocessor chip. The first system, when fully configured, uses 70 each of the two types of processors. A 53 processor system has been operated for several months with essentially no down time by computer operators in the Fermilab Computer Center, performing at nearly the capacity of 6 CDC Cyber 175 mainframe computers. The VME crates in which the processing ''nodes'' sit are connected via a high speed ''Branch Bus'' to one or more MicroVAX computers which act as hosts handling system resource management and all I/O in offline applications. An interface from Fastbus to the Branch Bus has been developed for online use which has been tested error free at 20 Mbytes/sec for 48 hours. ACP hardware modules are now available commercially. A major package of software, including a simulator that runs on any VAX, has been developed. It allows easy migration of existing programs to this multiprocessor environment. This paper describes the ACP Multiprocessor System and early experience with it at Fermilab and elsewhere

Analyzing terabytes of data at Fermilab

Computing demands of High Energy Physics are increasing steadily due to the demands of larger datasets and increasingly sophisticated detector systems and analysis techniques. Fermilab has been meeting these demands by the use of many different computing techniques. Most of these techniques attempt to utilized the most cost-effective computing resources while providing effective solutions to the problems that are created by multi-Terabyte data samples and large collaborations. New strategies are being developed to allow improved access to the data

Testing of the superconducting solenoid for the Fermilab collider detector

International Nuclear Information System (INIS)

Fast, R.W.; Holmes, C.N.; Kephart, R.D.

1985-07-01

The 3 m phi x 5 m long x 1.5 T superconducting solenoid for the Fermilab Collider Detector has been installed at Fermilab and was tested in early 1985 with a dedicated refrigeration system. The refrigerator and 5.6-Mg magnet cold mass were cooled to 5 K in 210 hours. After testing at low currents, the magnet was charged to the design current of 5 kA in 5-MJ steps. During a 390 A/min charge a spontaneous quench occurred at 4.5 kA due to insufficient liquid helium flow. Three other quenches occurred during ''slow'' discharges which were nevertheless fast enough to cause high eddy current heating in the outer support cylinder. Quench behavior is well understood and the magnet is now quite reliable

Emittance measurement and modeling for the Fermilab Booster

Directory of Open Access Journals (Sweden)

Xiaobiao Huang

2006-01-01

Full Text Available Turn-by-turn beam profile data measured at the Fermilab Booster are studied. Lattice models with experimental accelerator ramping parameters are used to obtain the lattice functions for data analysis. We studied the horizontal and vertical emittance growth behavior in different stages of a booster ramping cycle and its relation to the beam intensity. The transverse and longitudinal components in the horizontal beam width are separated by a fitting model which makes use of the different scaling rules of the beam momentum. We analyze the post-transition horizontal beam size oscillation based on a model where the longitudinal phase-space mismatch has resulted from rf voltage mismatch during the transition-energy crossing. We carried out systematic multiparticle simulation to show that the source of the vertical emittance growth is a combination of the random errors in skew-quadrupole and dipole fields, and the systematic Montague resonance. The effect of random quadrupole field is small for the Fermilab Booster because the betatron envelope tunes are reasonably far away from the half-integer stop band.

The fabric for frontier experiments project at Fermilab

Kirby, Michael

2014-01-01

The FabrIc for Frontier Experiments (FIFE) project is a new, far-reaching initiative within the Fermilab Scientific Computing Division to drive the future of computing services for experiments at FNAL and elsewhere. It is a collaborative effort between computing professionals and experiment scientists to produce an end-to-end, fully integrated set of services for computing on the grid and clouds, managing data, accessing databases, and collaborating within experiments. FIFE includes 1) easy to use job submission services for processing physics tasks on the Open Science Grid and elsewhere; 2) an extensive data management system for managing local and remote caches, cataloging, querying, moving, and tracking the use of data; 3) custom and generic database applications for calibrations, beam information, and other purposes; 4) collaboration tools including an electronic log book, speakers bureau database, and experiment membership database. All of these aspects will be discussed in detail. FIFE sets the direction of computing at Fermilab experiments now and in the future, and therefore is a major driver in the design of computing services worldwide.

Fermilab experiment E-687: Recent results on charm

International Nuclear Information System (INIS)

Shephard, W.D.

1990-12-01

About 10 4 charm decays have been reconstructed from first-run data of Fermilab experiment E687 using the Fermilab Wide-Band Photon Spectrometer with the world's highest energy photon beam. Charm selection strategies and preliminary results are discussed. Lifetime values are (.50 ± .06 ± .03)ps for the D s + and (.20 ± .03 ± .03)ps for the Λ c + . Preliminary D + and D 0 lifetimes are consistent with current world averages. Signals for charm baryon and Cabibbo-suppressed charm meson decays are shown. Preliminary branching ratios are: B(D 0 → π + π - π + π - )/B(D 0 → K - π + π + π - ) = .10 ± .02 ± .02; B(D 0 → bar K 0 K + K - )/B(D 0 → bar K 0 π + π - ) = .20 ± .06(stat); B(D 0 → bar K 0 φ)/B(D 0 → bar K 0 π + π - ) = .16 ± .06(stat). Preliminary results are given on D* ± and D ±,0 photoproduction for photon energies from 100 to 350 GeV. 13 refs., 3 figs

This paper describes an experimental search for antiproton decay at the Fermilab Antiproton Accumulator. The E868 (APEX) experimental setup is described. The APEX data is expected to be sensitive to antiproton decay if the antiproton lifetimes is less than a few times 100,000 years

Remote manipulator experience in target train maintenance at Fermilab

International Nuclear Information System (INIS)

Butala, S.W.

1984-01-01

When Fermilab was designed in the late 1960's and early 1970's, it was anticipated that Neutrino target train servicing could be costly in terms of personnel radiation exposure. This was based in part on the expectation that target intensities of at least 1E13 protons/pulse would be required to produce several neutrino interactions in a large bubble chamber detector. This was indeed later proven to be the case and historically the Neutrino beamline has been targeted with about one half of the protons available from the Main Ring. It was believed that much of the occupational radiation dose from the Neutrino Area could be spared by utilization of a remote manipulator system, which was eventually installed. It is the purpose of this report to examine the use of the Fermilab remote manipulator system and evaluate its cost effectiveness and success as an ALARA (As Low As Reasonably Achievable) tool. 16 references, 11 figures

2016-06-01

In a partnership with SLAC National Accelerator Laboratory (SLAC) and Jefferson Lab, Fermilab will assemble and test 17 of the 35 total 1.3 GHz cryomodules for the Linac Coherent Light Source II (LCLS-II) Project. These devices will be tested at Fermilab's Cryomodule Test Facility (CMTF) within the Cryomodule Test Stand (CMTS-1) cave. The problem of magnetic pollution became one of major issues during design stage of the LCLS-II cryomodule as the average quality factor of the accelerating cavities is specified to be 2.7 x 10¹⁰. One of the possible ways to mitigate the effect of stray magnetic fields and to keep it below the goal of 5 mGauss involves the application of low permeable materials. Initial permeability and magnetic measurement studies regarding the use of 316L stainless steel material indicated that cold work (machining) and heat affected zones from welding would be acceptable.

Dilepton Production at Fermilab and RHIC

International Nuclear Information System (INIS)

Peng, J.C.; McGaughey, P.L.; Moss, J.M.

1999-01-01

Some recent results from several fixed-target dimuon production experiments at Fermilab are presented. In particular, we discuss the use of Drell-Yan data to determine the flavor structure of the nucleon sea, as well as to deduce the energy-loss of partons traversing nuclear medium. Future dilepton experiments at RHIC could shed more light on the flavor asymmetry and possible charge-symmetry-violation of the nucleon sea. Clear evidence for scaling violation in the Drell-Yan process could also be revealed at RHIC

Motivation, affect, and hemispheric asymmetry: power versus affiliation.

Science.gov (United States)

Kuhl, Julius; Kazén, Miguel

2008-08-01

In 4 experiments, the authors examined to what extent information related to different social needs (i.e., power vs. affiliation) is associated with hemispheric laterality. Response latencies to a lateralized dot-probe task following lateralized pictures or verbal labels that were associated with positive or negative episodes related to power, affiliation, or achievement revealed clear-cut laterality effects. These effects were a function of need content rather than of valence: Power-related stimuli were associated with right visual field (left hemisphere) superiority, whereas affiliation-related stimuli were associated with left visual field (right hemisphere) superiority. Additional results demonstrated that in contrast to power, affiliation primes were associated with better discrimination between coherent word triads (e.g., goat, pass, and green, all related to mountain) and noncoherent triads, a remote associate task known to activate areas of the right hemisphere.

Fermilab enters the Tevatron era

International Nuclear Information System (INIS)

Southworth, B.

1985-01-01

The advent of the world's first superconducting accelerator/storage ring has transformed the physics programme at the Fermi National Accelerator Laboratory. The primary and secondary beam energies (and the coming colliding beam energies) are double those previously available at Fermilab and at the CERN SPS. There is heavy investment in the fixed target programme to use these beam energies and, at present, even more pressure is driving the preparations for proton-antiproton colliding beam operation at energies up to 1 TeV per beam. Since it is the revitalized machine which is making all this possible, we begin with news on machine performance and development. (orig.).

Post-conflict affiliation as conflict management in captive bottlenose dolphins (Tursiops truncatus).

2015-09-22

Post-conflict affiliation between former opponents or between one of the former opponents and bystanders might have the function of conflict management, which reduces the costs associated with aggressions. One of the suggested functions of post-conflict affiliation is decreased renewed aggressions directed from aggressors to victims. However, the effect of post-conflict affiliation on renewed aggressions by victims has not been investigated. We examined whether post-conflict affiliations decreased the number of renewed aggressions initiated by winners or losers in captive bottlenose dolphins. Both winners and losers initiated renewed aggressions. However, these aggressions decreased after post-conflict affiliation between former opponents, initiated by bystanders to winners, initiated by losers to bystanders, and initiated by bystanders to losers. Post-conflict affiliation between former opponents is suggested to function as reconciliation. Post-conflict affiliation initiated by losers to bystanders is suggested to function as the protection of losers. Post-conflict affiliations initiated by bystanders to one of former opponents are suggested to function as both appeasement and protection of the opponent who affiliates with bystanders.

Investigation of hadronic matter at the Fermilab Tevatron Collider. Technical progress report

International Nuclear Information System (INIS)

Anderson, E.W.

1985-01-01

Hadronic matter at very high energy densities is investigated. The present experimental effort is focused on a search for a new quark-gluon plasma phase expected to occur when temperatures of 240 MeV are achieved. Instrumentation for several unique signatures is being developed to exploit the first operation of the Fermilab Tevatron Collider in 1986. The capital projects funded under this contract are a 240-element trigger hodoscope array, and in phase II a segmented photon detector. For these projects $172K are requested for the period 1986 February 1 through 1987 January 31 to complete the trigger hodoscope, and $160K for the period 1987 February 1 through 1988 January 31 to construct a portion of the photon detector. These figures are as presented in the original proposal. Due to budget constraints on the Fermilab experimental support program, we will not be able to receive the full complement of necessary electronics from the Fermilab PREP pool in the required period. Consequently, an additional $35K is requested for the period 1986 February 1 through 1987 January 31 for a portion of the electronics for the 240-channel trigger hodoscope. For the same reasons, Fermilab cannot provide the required magnet on schedule; a one year delay is proposed. As this would seriously impact our physics goals, the collaboration is attempting to fund the magnet without delay through the universities. Efforts to date have concentrated on the design and testing of the hodoscope. Extensive measurements on the radiation levels and effects during the various accelerator cycles have been made. These data are essential to the proper selection of scintillator and design of electronics. These tests are now complete, and final construction is beginning. 11 refs

Experiment E769 at Fermilab obtained charm hadroproduction data during the 1987-88 Fixed Target running period with a 250 GeV hadron beam incident on thin target foils of Be, Al, Cu, and W. From an analysis of 25% of the recorded 400M trigger sample we have explored the Feynman x, p t 2 and the atomic number dependence of charm quark production using samples of D + and D 0 mesons. 7 refs., 4 figs

Impedances and beam stability issues of the Fermilab recycler ring

International Nuclear Information System (INIS)

Ng, King-Yuen.

1996-04-01

The Fermilab Recycler Ring (permanent magnets) will be built on top of the Fermilab Main Injector sharing the same tunnel; its main function is to recycle the anti-protons after a store in the Tevatron and to provide storage for them after after accumulation and cooling in the Accumulator. Estimates of coupling impedances show domination by space charge. Examination of longitudinal instabilities shows that microwave instability will not occur if there are only N = 2.53 x 10 12 anti-protons in the beam. Longitudinal coupling-bunch instability during injection stacking does not appear possible because of long bunch lengths/short bunch gaps and lack of sharp resonances. Transverse instability, on the other hand, cannot be Landau damped by the momentum spread in the beam, but it can be cured by a small spread in the betatron tunes (either from space charge or an octupole)

Future prospects of KL -> π0νanti-ν experiment at Fermilab

International Nuclear Information System (INIS)

Hsiung, Yee B.

2000-01-01

The authors reviewed the current status of a proposed KAMI (Kaon at Main Injector) experiment at Fermilab to measure the direct CP-violating K L (r a rrow) π 0 νanti-ν decay. Good progress and encouraging results have been made in the past two years for measuring the required photon veto inefficiencies for both CsI and lead-scintillator detectors in a test beam at INS-KEK Japan. New beam test with 150 GeV Main Injector protons has also been scheduled in January 2000 at Fermilab using the existing KTeV detector with two new beam calorimeters. Prospects of a feasible KAMI experiment in the future is discussed here

Brief summary of staffing levels at Fermilab during initial construction years

International Nuclear Information System (INIS)

Livdahl, P.V.

1983-11-01

This paper very briefly summarizes the work of the various groups that were involved from the beginning through the end of the initial construction phase of the Fermilab project (defined here to be July 1, 1972) and the final construction or completion phase which is here defined as December 31, 1973. The numbers in this report have been gathered by examining the personnel records of Fermilab with the research being done by Chuck Marofske, the Head of Laboratory Services and his staff and by assembling information from the memories of people still with the laboratory in 1983. Since there was much mobility within the laboratory during the construction years and frequent reorganizations were the norm, the numbers presented herein can not be considered to be more accurate than about +- 5%

QA [Quality Assurance] role in advanced energy activities: Towards an /open quotes/orthodox/close quotes/ Quality Program: Canonizing the traditions at Fermilab

International Nuclear Information System (INIS)

Bodnarczuk, M.W.

1988-02-01

After a brief description of the goal of Fermi National Accelerator Laboratory (Fermilab) this paper poses and answers three questions related to Quality Assurance (QA) at the Laboratory. First, what is the difference between 'orthodox' and 'unorthodox' QA and is there a place for 'orthodox' QA at a laboratory like Fermilab? Second, are the deeper philosophical and cultural frameworks of high-energy physics acommodating or antagonistic to an 'orthodox' QA Program? Finally, faced with the task of developing an institutional QA program for Fermilab where does one begin? The paper is based on experience with the on-going development and implementation of an institutional QA Program at Fermilab. 10 refs

Rare KL decays at Fermilab

Schnetzer, St.

1997-01-01

Recent results and the future prospects for rare K L decay at Fermilab are described. A summary of all rare decay results from E799 Phase I (the 1991 run) are presented. Three new results: K L → e + e - μ + μ - , K L → π 0 μe, and π 0 → e + e - e + e - are discussed in detail. Improvements for KTeV (the 1996-1997 run) are discussed and the expected sensitivities listed. Finally, the KAMI program for rare decays with the Main Injector (2000 and beyond) is presented with emphasis on a search for the decay K L → π 0 νν-bar at O(10 -12 ) single-event-sensitivity.

2017-12-22

The Fermilab muon g-2 experiment will measure the muon anomalous magnetic moment $a_{\\mu}$ to 140 ppb – a four-fold improvement over the earlier Brookhaven experiment. The measurement of $a_{\\mu}$ is well known as a unique test of the standard model with broad sensitivity to new interactions, particles and phenomena. The goal of 140 ppb is commensurate with ongoing improvements in the SM prediction of the anomalous moment and addresses the longstanding 3.5$\\sigma$ discrepancy between the BNL result and the SM prediction. In this article I discuss the physics motivation and experimental technique for measuring $a_{\\mu}$, and the current status and the future work for the project.

The Fabric for Frontier Experiments (FIFE) project is a major initiative within the Fermilab Scientific Computing Division charged with leading the computing model for Fermilab experiments. Work within the FIFE project creates close collaboration between experimenters and computing professionals to serve high-energy physics experiments of differing size, scope, and physics area. The FIFE project has worked to develop common tools for job submission, certificate management, software and reference data distribution through CVMFS repositories, robust data transfer, job monitoring, and databases for project tracking. Since the projects inception the experiments under the FIFE umbrella have significantly matured, and present an increasingly complex list of requirements to service providers. To meet these requirements, the FIFE project has been involved in transitioning the Fermilab General Purpose Grid cluster to support a partitionable slot model, expanding the resources available to experiments via the Open Science Grid, assisting with commissioning dedicated high-throughput computing resources for individual experiments, supporting the efforts of the HEP Cloud projects to provision a variety of back end resources, including public clouds and high performance computers, and developing rapid onboarding procedures for new experiments and collaborations. The larger demands also require enhanced job monitoring tools, which the project has developed using such tools as ElasticSearch and Grafana. in helping experiments manage their large-scale production workflows. This group in turn requires a structured service to facilitate smooth management of experiment requests, which FIFE provides in the form of the Production Operations Management Service (POMS). POMS is designed to track and manage requests from the FIFE experiments to run particular workflows, and support troubleshooting and triage in case of problems. Recently a new certificate management infrastructure called

Social affiliation in same-class and cross-class interactions.

Côté, Stéphane; Kraus, Michael W; Carpenter, Nichelle C; Piff, Paul K; Beermann, Ursula; Keltner, Dacher

2017-02-01

Historically high levels of economic inequality likely have important consequences for relationships between people of the same and different social class backgrounds. Here, we test the prediction that social affiliation among same-class partners is stronger at the extremes of the class spectrum, given that these groups are highly distinctive and most separated from others by institutional and economic forces. An internal meta-analysis of 4 studies (N = 723) provided support for this hypothesis. Participant and partner social class were interactively, rather than additively, associated with social affiliation, indexed by affiliative behaviors and emotions during structured laboratory interactions and in daily life. Further, response surface analyses revealed that paired upper or lower class partners generally affiliated more than average-class pairs. Analyses with separate class indices suggested that these patterns are driven more by parental income and subjective social class than by parental education. The findings illuminate the dynamics of same- and cross-class interactions, revealing that not all same-class interactions feature the same degree of affiliation. They also reveal the importance of studying social class from an intergroup perspective. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Fermilab has tested two compressors for possible installation in the satellite refrigerator buildings of the Tevatron cryogenic system. Both Creare Inc. and Cryogenic Consultants Inc. have supplied units for evaluation. The Creare machine, a high speed centrifugal pump/compressor, yielded 60% adiabatic efficiency but had difficulty withstanding two-phase flow. Cryogenic Consultants provided a reciprocating unit which achieved 59% efficiency and, although lacking the operating characteristics of the turbomachine, endured throughout testing and was insensitive to two-phase flow.

The Fermilab ACNET upgrade

International Nuclear Information System (INIS)

Briegel, C.; Johnson, G.; Winterowd, L.

1990-01-01

The Fermilab Accelerator Controls Network (ACNET) upgrade consists of a new physical medium (IEEE 802.5 token ring), additions to the calling sequence and added processor support. ACNET is the accelerator control backbone network for all data communication. A proprietary network was replaced by an IEEE standard enabling an open network with excellent characteristics for the control system. The calling sequence was enhanced for the added capabilities of the token-ring interface such as 'gather-read' and 'scatter-write'. In addition to prior support of DEC PDP11s under RS11M and VAXs under VMS, the ACNET calling sequence was implemented in the language C for the IBM PC with MS-DOS and Motorola 680x0 with MTOS using VME bus. Additional support is in progress for Intel 80x86 with MTOS using Multibus II. (orig.)

As the Fermilab Tevatron Collider program draws to a close, a strategy has emerged of an experimental program built around the high intensity frontier. The centerpiece of this program is a superconducting H- linac that will support world leading programs in long baseline neutrino experimentation and the study of rare processes. Based on technology shared with the International Linear Collider, Project X will provide multi-MW beams at 60-120 GeV from the Main Injector, simultaneous with very high intensity beams at lower energies. Project X also supports development of a Muon Collider as a future facility at the energy frontier.

Because of their sensitivity and high level of discrimination, short tandem repeat (STR) maker systems are currently the method of choice in routine forensic casework and data banking, usually in multiplexes up to 15-17 loci. Constraints related to sample amount and quality, frequently encountered in forensic casework, will not allow to change this picture in the near future, notwithstanding the technological developments. In this study, we present a free online calculator named PopAffiliator ( http://cracs.fc.up.pt/popaffiliator ) for individual population affiliation in the three main population groups, Eurasian, East Asian and sub-Saharan African, based on genotype profiles for the common set of STRs used in forensics. This calculator performs affiliation based on a model constructed using machine learning techniques. The model was constructed using a data set of approximately fifteen thousand individuals collected for this work. The accuracy of individual population affiliation is approximately 86%, showing that the common set of STRs routinely used in forensics provide a considerable amount of information for population assignment, in addition to being excellent for individual identification.

Self-protective function of post-conflict bystander affiliation in mandrills.

Directory of Open Access Journals (Sweden)

Gabriele Schino

Full Text Available BACKGROUND: Affiliative interactions exchanged between victims of aggression and individuals not involved in the original aggression (bystanders have been observed in various species. Three hypothetical functions have been proposed for these interactions: consolation, self-protection and substitute reconciliation, but data to test them are scanty. METHODOLOGY/PRINCIPAL FINDINGS: We conducted post-conflict and matched control observations on a captive group of mandrills (Mandrillus sphinx. We found that victims often redirected aggression to bystanders, that they received most affiliation from those bystanders that were frequently the target of redirection, and that bystander affiliation reduced the likelihood of redirection. Bystander affiliation did not reduce the victim's distress (as measured by its scratching rates and was not received primarily from kin/friends. Finally, bystander affiliation did not reduce the likelihood of renewed aggression from the original aggressor. CONCLUSIONS/SIGNIFICANCE: These results provide support for the self-protection hypothesis but not for the consolation and substitute reconciliation hypotheses.

In July 1988 a small working group was formed to develop a conceptual design for a high field superconducting dipole magnet suitable for use in the Phase III upgrade at Fermilab. The Phase III upgrade calls for replacement of the existing Tevatron with higher field magnets to boost the energy of the fixed target program to 1.5 TeV and to add a 1.8 TeV collider program. As the work of this group evolved it became clear that the resulting design might be applicable to more than just the proposed upgrade. In particular, it seemed plausible that the work might be applicable to the high energy booster (HEB) for the SSC. At the Breckenridge Workshop in August 1989 interest in a third project began to surface, namely the revamping of an earlier proposal for a dedicated collider at Fermilab. We refer to this proposal as the FNAL Independent Collider. The requirements for the dipole magnets for this independent collider appear to be remarkably similar to those proposed for the Phase III upgrade and the SSC HEB. The purpose of this report is to compare the conceptual design of the dipoles developed for the Phase III proposal with the requirements of those for the SSC HEB, the FNAL Independent Collider, and a hybrid design which could serve the needs of both. The Phase III design will be used as the reference point for parameter scaling. 4 figs., 3 tabs

Fermilab is developing and investigating different high-field magnets (HFM) for present and future accelerators. The HFM R&D program focused on the 10-12 T magnets based on Nb/sub 3/Sn superconductor and explored both basic magnet technologies for brittle superconductors-wind-and-react and react-and-wind. Magnet design studies in support of LHC upgrades and VLHC were conducted. A series of 1-m long cos-theta dipole models based on the wind-and-react technique was fabricated and tested. Three 1-m long flat racetracks and the common coil dipole model, based on a single-layer coil and react-and-wind technique, were also fabricated and tested. Extensive theoretical and experimental studies of electro-magnetic instabilities in Nb/sub 3/Sn strands, cables and magnets were performed and led to a successful 10 T dipole model. This paper presents the details of Fermilab's HFM program, reports its status and major results, and formulates the next steps for the program.

The Short-Baseline Neutrino (SBN) physics program will involve three LAr-TPC detectors located along the Booster Neutrino Beam (BNB) at Fermilab. This new SBN Program will deliver a rich and compelling physics opportunity, including the ability to resolve a class of experimental anomalies in neutrino physics and to perform the most sensitive search to date for sterile neutrinos at the eV mass-scale through both appearance and disappearance oscillation channels. The Program will be composed of an existing and operational detector known as Micro Boone (170 ton LAr mass) plus two new experiments known as the SBN Near Detector (SBND, ~ 260 ton) and the SBN Far Detector (SBN-FD, ~ 600 tons). Fermilab is now building two new facilities to house the experiments and incorporate all cryogenic and process systems to operate these detectors beginning in the 2018-2019 time frame. The SBN cryogenics are a collaborative effort between Fermilab and CERN. The SBN cryogenic systems for both detectors are composed of several s...

A lithium-lens focusing device will be used for the collection of 8-GeV antiprotons in the Fermilab Tevatron I Project. The details of the mechanical and electrical design of the Fermilab lens and its associated toroidal transformer are discussed. The lens, with a radium of 1 cm and length 15 cm, is expected to achieve gradients of 1000 T/m for a focal distance of 0.225 m. The gradient requires a current on the order of 5 x 10 5 A, resulting in large electromagnetic and thermal stresses. The power-supply discharge current and the effect of the inductance of the power leads and connections are minimized by the use of a toroidal matching transformer surrounding the lens itself

This study examined parents' perceptions/awareness and internalization of public courtesy stigma (affiliate stigma) about their children's inattentive and hyperactive/impulsive symptoms, and associations between parental affiliate stigma, parental negativity expressed toward the child, and child social functioning. Participants were families of 63 children (ages 6-10; 42 boys) with attention-deficit/hyperactivity disorder, assessed in a cross-sectional design. After statistical control of children's severity of inattentive and hyperactive/impulsive symptoms (as reported by parents and teachers), parents' self-reports of greater affiliate stigma were associated with more observed negative parenting. The associations between high parental affiliate stigma and children's poorer adult informant-rated social skills and greater observed aggression were partially mediated by increased parental negativity. As well, the positive association between children's adult informant-rated aggressive behavior and parental negativity was partially mediated by parents' increased affiliate stigma. Parental affiliate stigma about their children's inattentive and hyperactive/impulsive symptoms may have negative ramifications for parent-child interactions and children's social functioning. Clinical implications for parent training interventions are discussed.

In this paper the technique used to control the relative timing and synchronization of the major accelerator systems at Fermilab is described. The various operating modes of the injector accelerators include fixed target and colliding beam operation in conjunction with simultaneous machine studies. For example, in a 60 second interval the conventional main Ring may be called upon to: (a) load the Tevatron with 12 high intensity Booster batches each containing 82 rf bunches at 150 GeV, (b) transfer a Booster batch at 8 GeV with 8 rf bunches to the Debuncher or Accumulator, (c) accelerate high intensity beam several times to 120 GeV for antiproton production, and (d) accelerate beam to 150 GeV for Main Ring studies. In the case of colliding beam operation, the different tasks can be even more varied. All this requires a simple, flexible means of coordination

Beam Based RF Voltage Measurements and Longitudinal Beam Tomography at the Fermilab Booster

Energy Technology Data Exchange (ETDEWEB)

Bhat, C. M. [Fermilab; Bhat, S. [Fermilab

2017-10-19

Increasing proton beam power on neutrino production targets is one of the major goals of the Fermilab long term accelerator programs. In this effort, the Fermilab 8 GeV Booster synchrotron plays a critical role for at least the next two decades. Therefore, understanding the Booster in great detail is important as we continue to improve its performance. For example, it is important to know accurately the available RF power in the Booster by carrying out beam-based measurements in order to specify the needed upgrades to the Booster RF system. Since the Booster magnetic field is changing continuously measuring/calibrating the RF voltage is not a trivial task. Here, we present a beam based method for the RF voltage measurements. Data analysis is carried out using computer programs developed in Python and MATLAB. The method presented here is applicable to any RCS which do not have flat-bottom and flat-top in the acceleration magnetic ramps. We have also carried out longitudinal beam tomography at injection and extraction energies with the data used for RF voltage measurements. Beam based RF voltage measurements and beam tomography were never done before for the Fermilab Booster. The results from these investigations will be very useful in future intensity upgrades.

Thousands of analog signals are monitored in different areas of the Fermilab accelerator complex. For general purposes, analog signals are sent over coaxial or twinaxial cables with varying lengths, collected at fan-in boxes and digitized with 12 bit multiplexed ADCs. For higher resolution requirements, analog signals are digitized at sources and are serially sent to the control system. This paper surveys ADC subsystems that are used with the accelerator control systems and discusses practical problems and solutions, and it describes how analog data are presented on the console system

We explore an alternative strategy to determine the neutrino mass hierarchy by making use of possible future neutrino facilities at Fermilab. Here, we use CPT-conjugate neutrino channels, exploiting a ν μ beam from the NuMI beamline and a ν e beam from a beta-beam experimental setup. Both experiments are performed at approximately the same /L. We present different possible accelerator scenarios for the beta-beam neutrino setup and fluxes. This CPT-conjugate neutrino channel scenario can extract the neutrino mass hierarchy down to sin 2 2θ 13 ≅0.02.

Postdoctoral pharmacy industry fellowship programs and the employment of fellowship graduates are described. A list of postgraduate industry fellowships was gathered from the 2009 ASHP Midyear Clinical Meeting. Data regarding program characteristics were collected using the Personnel Placement Service database and program-specific brochures. After data compilation, a standardized survey was sent in January 2010 via e-mail to the point of contact for all programs to confirm the accuracy of the program's characteristics. Only academically affiliated industry fellowship programs were analyzed. Retrospective data were collected regarding the first position of employment for all fellows who graduated from the program between 2005 and 2009 and the position of those same individuals at the time of survey completion. Surveys were sent to 64 postgraduate industry fellowship programs affiliated with a school of pharmacy, 56 (87.5%) of whom responded. The departmental breakdown for positions offered (n = 75) across all academically affiliated industry fellowship programs (including nonresponders) was as follows: medical affairs (38.7%, n = 29), clinical research (32.0%, n = 24), regulatory affairs (9.3%, n = 7), commercial (8.0%, n = 6), health economics and outcomes research (8.0%, n = 6), and pharmacovigilance (4.0%, n = 3). Data from fellows during years 1-5 after completion of the industry fellowship indicated that 90.5% of former fellows remained in the industry (n = 238). The postgraduate industry fellowship programs surveyed indicated that the majority of fellowship graduates continued to hold positions in industry after program completion. The majority of industry fellowships and subsequent job placements occurred in the areas of medical affairs, clinical research, and regulatory affairs.

1994-01-01

This paper reports the results of an exploratory study that investigated the influence of technical uncertainty on the use of information and information sources by U.S. industry-affiliated aerospace engineers and scientists in completing or solving a project, task, or problem. Data were collected through a self-administered questionnaire. Survey participants were U.S. aerospace engineers and scientists whose names appeared on the Society of Automotive Engineers (SAE) mailing list. The results support the findings of previous research and the following study assumptions. Information and information-source use differ for projects, problems, and tasks with high and low technical uncertainty. As technical uncertainty increases, information-source use changes from internal to external and from informal to formal sources. As technical uncertainty increases, so too does the use of federally funded aerospace research and development (R&D). The use of formal information sources to learn about federally funded aerospace R&D differs for projects, problems, and tasks with high and low technical uncertainty.

Emergent patterns of social affiliation in primates, a model.

Directory of Open Access Journals (Sweden)

Ivan Puga-Gonzalez

2009-12-01

Full Text Available Many patterns of affiliative behaviour have been described for primates, for instance: reciprocation and exchange of grooming, grooming others of similar rank, reconciliation of fights, and preferential reconciliation with more valuable partners. For these patterns several functions and underlying cognitive processes have been suggested. It is, however, difficult to imagine how animals may combine these diverse considerations in their mind. Although the co-variation hypothesis, by limiting the social possibilities an individual has, constrains the number of cognitive considerations an individual has to take, it does not present an integrated theory of affiliative patterns either. In the present paper, after surveying patterns of affiliation in egalitarian and despotic macaques, we use an individual-based model with a high potential for self-organisation as a starting point for such an integrative approach. In our model, called GrooFiWorld, individuals group and, upon meeting each other, may perform a dominance interaction of which the outcomes of winning and losing are self-reinforcing. Besides, if individuals think they will be defeated, they consider grooming others. Here, the greater their anxiety is, the greater their "motivation" to groom others. Our model generates patterns similar to many affiliative patterns of empirical data. By merely increasing the intensity of aggression, affiliative patterns in the model change from those resembling egalitarian macaques to those resembling despotic ones. Our model produces such patterns without assuming in the mind of the individual the specific cognitive processes that are usually thought to underlie these patterns (such as recordkeeping of the acts given and received, a tendency to exchange, memory of the former fight, selective attraction to the former opponent, and estimation of the value of a relationship. Our model can be used as a null model to increase our understanding of affiliative

Despite the generous allotment of time it was not possible to do more than scratch the surface of some subjects. The collider experiments, using the measurements of the W mass and with top search and mass limits, are approaching the situation where a statement about the Higgs mass, or a sensitive test of the consistency of the standard model become a possibility. Subjects discussed were: (1) cross-sections, QCD measurements; (2) decay physics; (3) W/Z physics; (4) searches for new physics; and (5) search for top quark

Why electric utilities and affiliates are handicapped in a partly regulated and partly competitive environment

Energy Technology Data Exchange (ETDEWEB)

St.Marie, S.M.

1999-11-01

As the electric utility industry continues to go through the process of restructuring, utilities are finding themselves operating not only as regulated entities but also as firms that compete for customers and sales. Some services, including services associated with distribution, are being unbundled or peeled off from the core of operations and, where possible, are being opened to competition. But these partly regulated and partly competitive areas are treacherous for utilities and their affiliates, who will be handicapped in their competitive efforts and subject to constraints not placed on their competitors. There are good reasons why such difficulties should be expected. And there are guidelines for pricing and competitive positioning that can assist in avoiding the worst problems. The first step is to recognize the archetypes of the regulated electric distribution utility and the competitive firm. In plotting their deregulation strategies, utilities and their affiliates must recognize that they will continue to be disadvantaged by regulators who are more concerned with keeping them in check than freeing them to compete.

2005-01-01

The Fermilab/NICADD photoinjector incorporates an L-band rf-gun capable of generating 1-10 nC bunches. The bunches are then accelerated to 16 MeV with a TESLA superconducting cavity. In the present paper we present parametric studies of transverse emittances and energy spread for a various operating points of the electron source (RF-gun E-field, laser length and spot size, and solenoid settings). We especially study the impact, on transverse emittance, of Gaussian and Plateau temporal distribution of the photocathode drive-laser.

Microprocessor based beam intensity and efficiency display system for the Fermilab accelerator

International Nuclear Information System (INIS)

Biwer, R.

1979-01-01

The Main Accelerator display system for the Fermilab accelerator gathers charge data and displays it including processed transfer efficiencies of each of the accelerators. To accomplish this, strategically located charge converters monitor the circulating internal beam of each of the Fermilab accelerators. Their outputs are processed via an asynchronously triggered, multiplexed analog-to-digital converter. The data is converted into a digital byte containing address code and data, then stores it into two 16-bit memories. One memory outputs the interleaved data as a data pulse train while the other interfaces directly to a local host computer for further analysis. The microprocessor based display unit synchronizes displayed data during normal operation as well as special storage modes. The display unit outputs data to the fron panel in the form of a numeric value and also makes digital-to-analog conversions of displayed data for external peripheral devices. 5 refs

How to make an affiliate model work--a case history.

Science.gov (United States)

Baumgartner, A J; Berns, A; Stedman, T W

1984-01-01

The North Shore Community Mental Health Center has an unusual mental health delivery system. "Out-stationed" staff work in affiliated agencies, yet are employees of the NSCMHC. This service configuration is the result of an arduous planning process which weighed the advantages of several organizational models. On one extreme was a "Centralized" model, wherein one organization was solely responsible for delivering mental health services. On the other extreme was an "Umbrella" model, wherein the organization acted as a fiscal conduit to several service providers. Somewhere in the middle a compromise was found with a "Lead Agency" model. Here, an organization provides the administrative structure, provides some services, and subcontracts the remaining services. The North Shore Community Mental Health Center adapted this system one step further. Rather than subcontracting services, it outstationed CMHC staff to affiliate agencies. United Cerebral Palsy Association of the North Shore is one of the CMHC's affiliates. The service need for family and play therapists resulted in two CMHC therapists being outstationed at UCP. The affiliation agreement between the two organizations specify the responsibilities and roles each have. The hiring process between the two organizations is an example of the duality of the system. Both agencies had interviewing roles, yet the final hiring decision was the affiliate's, since the employee would spend the majority of his/her time outstationed at the affiliate side. Outstationed staff integration to the North Shore Community Mental Health Center presented problems, however. Since these were new staff hired with federal funds, and since their visibility at the Center was minimal, they had some difficulty being identified as Center staff by existing employees.(ABSTRACT TRUNCATED AT 250 WORDS)

Religious affiliation at time of death - Global estimates and projections.

Science.gov (United States)

Skirbekk, Vegard; Todd, Megan; Stonawski, Marcin

2018-03-01

Religious affiliation influences societal practices regarding death and dying, including palliative care, religiously acceptable health service procedures, funeral rites and beliefs about an afterlife. We aimed to estimate and project religious affiliation at the time of death globally, as this information has been lacking. We compiled data on demographic information and religious affiliation from more than 2500 surveys, registers and censuses covering 198 nations/territories. We present estimates of religious affiliation at the time of death as of 2010, projections up to and including 2060, taking into account trends in mortality, religious conversion, intergenerational transmission of religion, differential fertility, and gross migration flows, by age and sex. We find that Christianity continues to be the most common religion at death, although its share will fall from 37% to 31% of global deaths between 2010 and 2060. The share of individuals identifying as Muslim at the time of death increases from 21% to 24%. The share of religiously unaffiliated will peak at 17% in 2035 followed by a slight decline thereafter. In specific regions, such as Europe, the unaffiliated share will continue to rises from 14% to 21% throughout the period. Religious affiliation at the time of death is changing globally, with distinct regional patterns. This could affect spatial variation in healthcare and social customs relating to death and dying.

2016-10-01

perpendicularly biased 2nd harmonic cavity is being designed and built for the Fermilab Booster. Its purpose is to flatten the bucket at injection and thus change the longitudinal beam distribution to decrease space charge effects. It can also help at extraction. The cavity frequency range is 76 – 106 MHz. The power amplifier will be built using the Y567B tetrode, which is also used for the fundamental mode cavities in the Fermilab Booster. We discuss recent progress on the cavity, the biasing solenoid design and plans for testing the tuner's garnet material

Bunch coalescing and bunch rotation in the Fermilab Main Ring: Operational experience and comparison with simulations

International Nuclear Information System (INIS)

Martin, P.S.; Wildman, D.W.

1988-01-01

The Fermilab Tevatron I proton-antiproton collider project requires that the Fermilab Main Ring produce intense bunches of protons and antiprotons for injection into the Tevatron. The process of coalescing a small number of harmonic number h=1113 bunches into a single bunch by bunch-rotating in a lower harmonic rf system is described.The Main Ring is also required to extract onto the antiproton production target bunches with as narrow a time spread as possible. This operation is also discussed. The operation of the bunch coalescing and bunch rotation are compared with simulations using the computer program ESME. 2 refs., 8 figs

Performance of 3.9 GHz SRF cavities at Fermilab's ILCTA_MDB nhorizontal test stand

2008-08-01

Fermilab is building a cryomodule containing four 3.9 GHz superconducting radio frequency (SRF) cavities for the Free electron LASer in Hamburg (FLASH) facility at the Deutsches Elektronen-SYnchrotron (DESY) laboratory. Before assembling the cavities into the cryomodule, each individual cavity is tested at Fermilab's Horizontal Test Stand (HTS). The HTS provides the capability to test fully-dressed SRF cavities at 1.8 K with high-power pulsed RF in order to verify that the cavities achieve performance requirements under these conditions. The performance at the HTS of the 3.9 GHz cavities built for FLASH is presented here.

Radiation skyshine calculation with MARS15 for the Mu2e Experiment at Fermilab

International Nuclear Information System (INIS)

Leveling, A.F.

2015-01-01

The Fermilab Antiproton source is to be re-purposed to provide an 8 kW proton beam to the Mu2e experiment by 1/3 integer, slow resonant extraction. Shielding provided by the existing facility must be supplemented with in-tunnel shielding to limit the radiation effective dose rate above the shield in the AP30 service building. In addition to the nominal radiation shield calculations, radiation skyshine calculations were required to ensure compliance with Fermilab Radiological Controls Manual. A complete model of the slow resonant extraction system including magnets, electrostatic septa, magnetic fields, tunnel enclosure with shield, and a nearby exit stairway are included in the model. The skyshine model extends above the beam enclosure surface to 10 km vertically and 5 km radially. (authors)

We have divided this description of our plans for the Laboratory program into seven parts. The first five sections describe the ongoing technical work and the broad range of physics opportunities available at Fermilab. These are organized into: our plans for the accelerator complex; our plans for facilities for performing experiments; the program of experiments we presently foresee; our plans for involvement with the LHC; and our plans for R ampersand D towards a future facility which recaptures the energy frontier. The final sections summarize: our priorities and our planning strategy for making choices for the future, and our budget request to support the Fermilab program as we approach the fundamental challenges of elementary particle physics over the next ten years

Operational experience with the Fermilab Linac

International Nuclear Information System (INIS)

Allen, L.J.; Lennox, A.J.; Schmidt, C.W.

1992-01-01

The Fermilab 200-MeV Linac has been in operation for nearly 22 years as a proton injector to the Booster synchrotron. It presently accelerates H - ions to 200 MeV for charge-exchange injection into the Booster and to 66 MeV for the production of neutrons at the Neutron Therapy Facility (NTF). The beam intensity is typically 35 mA with pulse widths of 30 μsec for the Booster for high energy physics and 57 μsec for NTF at a maximum of 15 pulses per sec. During a typical physics run of nine to twelve months, beam is available for greater than 98% of the scheduled time. The Linac history, operation, tuning, stability and reliability will be discussed.

2017-01-01

The Short-Baseline Neutrino (SBN) physics program at Fermilab and Neutrino Platform (NP) at CERN are part of the international Neutrino Program leading to the development of Long-Baseline Neutrino Facility/Deep Underground Neutrino Experiment (LBNF/DUNE) science project. The SBN program consisting of three Liquid Argon Time Projection Chamber (LAr-TPC) detectors positioned along the Booster Neutrino Beam (BNB) at Fermilab includes an existing detector known as MicroBooNE (170-ton LAr-TPC) plus two new experiments known as SBN’s Near Detector (SBND, ~260 tons) and SBN’s Far Detector (SBN-FD, ~760 tons). All three detectors have distinctly different design of their cryostats thus defining specific requirements for the cryogenic systems. Fermilab has already built two new facilities to house SBND and SBN-FD detectors. The cryogenic systems for these detectors are in various stages of design and construction with CERN and Fermilab being responsible for delivery of specific sub-systems. This contribution prese...

Overview of the Fermilab Muon g-2 Experiment

Energy Technology Data Exchange (ETDEWEB)

Kim, SeungCheon [Cornell U., Phys. Dept.

2015-01-01

The measurement of the anomalous magnetic moment of muon provides a precision test of the Standard Model. The Brookhaven muon g-2 experiment (E821) measured the muon magnetic moment anomaly with 0.54 ppm precision, a more than 3 deviation from the Standard Model predictions, spurring speculation about the possibility of new physics. The new g-2 experiment at Fermilab (E989) will reduce the combined statistical and systematic error of the BNL experiment by a factor of 4. An overview of the new experiment is described in this article.

Feasibility of short-lived radionuclide production at Fermilab

International Nuclear Information System (INIS)

Ten Haken, R.K.; Awschalom, M.; Rosenberg, I.

1985-01-01

The requirements for establishing a short-lived radionuclide production program at Fermilab are explored. Such a program would utilize beam from the linac portion of the injector much like the present Neutron Therapy Facility. It should be possible to use approximately 10 to 20 μA of 66-MeV protons for iodine-123 production. Several additional magnets would need to be acquired and a shielded target facility would need to be constructed. However, the feasibility of establishing such a program hinges upon its harmonious operation with the high energy physics program

Review of calorimetry in Fermilab fixed-target experiments

International Nuclear Information System (INIS)

Crisler, M.B.

1995-04-01

The fixed-target program at Fermilab comprises as many as thirteen simultaneous experiments in ten separate beamlines using beams of primary protons, pions, kaons, electrons, neutrinos, and muons. The fixed target beamlines were last in operation in the latter half of 1991, shutting down in 1992. The next fixed target run is scheduled for early 1996. This article describes some of the wide variety of calorimetric devices that were in use in the past run or to be used in the coming run. Special attention is devoted to the new devices currently under construction

Post-conflict affiliation by chimpanzees with aggressors: other-oriented versus selfish political strategy.

Directory of Open Access Journals (Sweden)

Teresa Romero

Full Text Available Consolation, i.e., post-conflict affiliation directed from bystanders to recent victims of aggression, has recently acquired an important role in the debate about empathy in great apes. Although similar contacts have been also described for aggressors, i.e., appeasement, they have received far less attention and their function and underlying mechanisms remain largely unknown. An exceptionally large database of spontaneous conflict and post-conflict interactions in two outdoor-housed groups of chimpanzees lends support to the notion that affiliation toward aggressors reduces the latter's aggressive tendencies in that further aggression was less frequent after the occurrence of the affiliation. However, bystander affiliation toward aggressors occurred disproportionally between individuals that were socially close (i.e., affiliation partners which suggest that it did not function to protect the actor itself against redirected aggression. Contrary to consolation behavior, it was provided most often by adult males and directed toward high ranking males, whereas females engaged less often in this behavior both as actors and recipients, suggesting that affiliation with aggressors is unlikely to be a reaction to the distress of others. We propose that bystander affiliation toward aggressors may function to strengthen bonds between valuable partners, probably as part of political strategies. Our findings also suggest that this post-conflict behavior may act as an alternative to reconciliation, i.e., post-conflict affiliation between opponents, in that it is more common when opponents fail to reconcile.

A kaon physics program at the Fermilab Main Injector

International Nuclear Information System (INIS)

Cooper, Peter

1997-11-01

In this paper we describe a triad of kaon experiments which will form the foundation of a kaon physics program at Fermilab in the Main Injector era. These three experiments; KAMI, CKM and CPT, span the range of experiment types discussed above. KAMI will use the existing neutral kaon beam and the KTeV detector as the basis of a search for the Standard Model ultra rare decay K L → π 0 ν anti ν decay mode is by far the theoretically cleanest measurement of the Standard Model parameter responsible for CP violation. CKM will measure the analogous charged kaon decay mode. Together these two experiments will determine the Standard Model contribution to CP violation independent of the B meson sector. The Standard Model parameters controlling CP violation must be observed to be the same in the K and B meson sectors in order to confirm the Standard Model as the sole source of CP violation in nature. CPT is a hybrid beam experiment using a high purity K + beam to produce a pure K 0 beam in order to search for violation of CPT symmetry at a mass scale up to the Planck mass. CPT also will measure new CP violation parameters to test the Standard Model and search for rare K S decays. The Fermilab infrastructure for such a physics program largely already exists. The Main Injector will be an existing accelerator by late 1998 with beam properties comparable to any of the previous ''kaon factory'' proposals. The KTeV detector and neutral kaon beamline are unsurpassed in the world and were originally designed to also operate with the 120 GeV Main Injector beam as KAMI. The Fermilab Meson laboratory was originally designed as an area for fixed target experiments using 200 GeV proton beams. The charged kaon beam experiments will naturally find a home there. Both charged kaon experiments, CKM and CPT, will share a new high purity RF separated charged kaon beam based on superconducting RF technology which will provide the highest intensity and purity charged kaon beam in the world

Getting along and getting ahead: Affiliation and dominance predict ambulatory blood pressure.

Science.gov (United States)

Baron, Carolynne E; Smith, Timothy W; Uchino, Bert N; Baucom, Brian R; Birmingham, Wendy C

2016-03-01

Based in interpersonal theory, the present study tested associations of trait affiliation (i.e., warmth vs. hostility) and control (i.e., dominance vs. submissiveness) with ambulatory blood pressure (ABP) and momentary affective experiences. Ninety-four married couples (mean age 29.6) completed trait affiliation and control measures, and a 1-day protocol with random interval-contingent measurements of ABP and affective experience. Higher trait control (i.e., dominance) predicted higher systolic and diastolic blood pressure (SBP, DBP) in men, but not in women. For both men and women, high affiliation predicted lower SBP. These associations occurred within individuals (i.e., actor effects) but not between spouses (i.e., partner effects). Dominance and affiliation also predicted momentary affect. Associations of dominance and affiliation with ABP may indicate a mechanism by which trait social behavior influences CVD risk. These findings also illustrate the interpersonal perspective as an integrative framework for research on psychosocial risk for CVD. (c) 2016 APA, all rights reserved).

A variety of current and voltage regulation systems have been installed in the Fermilab large magnet system. The four major systems employ different methods to achieve the desired degree of regulation. The methods include computer control and feedback, adaptive learning, precision (10ppm) current monitoring, and the use of feed-forward signals. This paper will explain each method used and present the measured regulation of the above systems. Also an overview of planned upgrades and improvements will be presented.

Simple model of electron cloud is developed in the paper to explain e-cloud instability of bunched proton beam in the Fermilab Recycler. The cloud is presented as an immobile snake in strong vertical magnetic field. The instability is treated as an amplification of the bunch injection errors from the batch head to its tail. Nonlinearity of the e-cloud field is taken into account. Results of calculations are compared with experimental data demonstrating good correlation.

Bunch coalescing in the Fermilab Main Ring

International Nuclear Information System (INIS)

Wildman, D.; Martin, P.; Meisner, K.; Miller, H.W.

1987-01-01

A new RF system has been installed in the Fermilab Main Ring to coalesce up to 13 individual bunches of protons or antiprotons into a single high-intensity bunch. The coalescing process consists of adiabatically reducing the h=1113 Main Ring RF voltage from 1 MV to less than 1 kV, capturing the debunched beam in a linearized h=53 and h=106 bucket, rotating for a quarter of a synchrotron oscillation period, and then recapturing the beam in a single h=1113 bucket. The new system is described and the results of recent coalescing experiments are compared with computer-generated particle tracking simulations

To examine the psychometrics of the Affiliate Stigma Scale using rigorous psychometric analysis: classical test theory (CTT) (traditional) and Rasch analysis (modern). Differential item functioning (DIF) items were also tested using Rasch analysis. Caregivers of relatives with mental illness (n = 453; mean age: 53.29 ± 13.50 years) were recruited from southern Taiwan. Each participant filled out four questionnaires: Affiliate Stigma Scale, Rosenberg Self-Esteem Scale, Beck Anxiety Inventory, and one background information sheet. CTT analyses showed that the Affiliate Stigma Scale had satisfactory internal consistency (α = 0.85-0.94) and concurrent validity (Rosenberg Self-Esteem Scale: r = -0.52 to -0.46; Beck Anxiety Inventory: r = 0.27-0.34). Rasch analyses supported the unidimensionality of three domains in the Affiliate Stigma Scale and indicated four DIF items (affect domain: 1; cognitive domain: 3) across gender. Our findings, based on rigorous statistical analysis, verified the psychometrics of the Affiliate Stigma Scale and reported its DIF items. We conclude that the three domains of the Affiliate Stigma Scale can be separately used and are suitable for measuring the affiliate stigma of caregivers of relatives with mental illness.

Use of an INR-style bunch-length detector in the Fermilab Linac

International Nuclear Information System (INIS)

McCrory, E.S.; Schmidt, C.W.; Feschenko, A.V.

1993-01-01

Device to accurately measure the phase extent of a linac beam is being developed for use in the Fermilab 400 MeV Linac Upgrade. Prototypes have been and are being tested. We have attempted to improve the original design from the Institute for Nuclear Research in Moscow (INR) to increase the resolution for adequate operation at 805 MHz. The device incorporating a new arrangement of lens and deflector, reported previously, cannot achieve the desired resolution. This paper describes the operation and the strengths and weaknesses of the three types of bunch-length detectors (BLDs) and the measurements made at this time. The differences among these devices is delineated by the relative position of the rf deflector and the electrostatic einsel lens, as follows: INR--Lens before deflector; Fermilab--Lens after deflector; H- beam; and FNAL/INR--Lens and deflector combined. To satisfy the goals of commissioning the new linac, a resolution of about 5 picoseconds (1 degree at 805 MHz) is desired

THE IMPACT OF AUDITOR AFFILIATION ON FINANCIAL STATEMENT RELEVANCE

Directory of Open Access Journals (Sweden)

Radu-Daniel LOGHIN

2017-12-01

Full Text Available The role of the audit report is to provide a level of trust to the professional judgment behind the financial statements of a company. The market for audit services is not a homogenous one, and large audit partners known as the Big 4 dominate with their partner networks in both developed and emerging markets. The scientific literature provides a rich background of studies linking auditor affiliation and auditor independence. The current exploratory paper tries to approach the issue of auditor independence and affiliation by drawing on the Ohlson model for a sample of 552 firm-year observations from the Borsa Istanbul, covering the 2014 and 2015 financial periods. The results reveal a strong correlation for the year 2015 between the Big 4 affiliation and the value of the equities, possibly suggesting a correlation between auditor independence and financial statement relevance.

Quirin, Markus; Meyer, Frank; Heise, Nils; Kuhl, Julius; Küstermann, Ekkehard; Strüber, Daniel; Cacioppo, John T

2013-06-01

Power versus affiliation motivations refer to two different strivings relevant in the context of social relationships. We used functional magnetic resonance imaging (fMRI) to determine neural structures involved in power versus affiliation motivation based on an individual differences approach. Seventeen participants provided self-reports of power and affiliation motives and were presented with love, power-related, and control movie clips. The power motive predicted activity in four clusters within the left prefrontal cortex (PFC), while participants viewed power-related film clips. The affiliation motive predicted activity in the right putamen/pallidum while participants viewed love stories. The present findings extend previous research on social motivations to the level of neural functioning and suggest differential networks for power-related versus affiliation-related social motivations.

Limits on the transverse phase space density in the Fermilab Booster

International Nuclear Information System (INIS)

Ankenbrandt, C.; Holmes, S.D.

1987-09-01

Recent results on intensity and transverse density limitations in the Fermilab 8-GeV Booster are presented. The evidence suggests that the limits are set by incoherent space-charge effects at low energy. Data are interpreted in terms of the space-charge tune shift and possible means of improving performance further are discussed. 8 refs., 3 figs

2017-08-01

The planned neutrino program at Fermilab requires large proton beam intensities in excess of 2 MW. Measuring the transverse profiles of these high intensity beams is challenging and often depends on non-invasive techniques. One such technique involves measuring the deflection of a probe beam of electrons with a trajectory perpendicular to the proton beam. A device such as this is already in use at the Spallation Neutron Source at ORNL and a similar device has been installed in the Main Injector at Fermilab. Commissioning of the device is in progress with the goal of having it operational by the end of the year. The status of the commissioning and initial results will be presented

The role of political affiliation in employment decisions: A model and research agenda.

Science.gov (United States)

Roth, Philip L; Goldberg, Caren B; Thatcher, Jason B

2017-09-01

Organizational researchers have studied how individuals identify with groups and organizations and how this affiliation influences behavior for decades (e.g., Tajfel, 1982). Interestingly, investigation into political affiliation and political affiliation similarity in the organizational sciences is extremely rare. This is striking, given the deep political divides that exist between groups of individuals described in the political science literature. We draw from theories based on similarity, organizational identification, and person-environment fit, as well as theoretical notions related to individuating information, to develop a model, the political affiliation model (PAM), which describes the implications of political affiliation and political similarity for employment decisions. We set forth a number of propositions based on PAM, to spur future research in the organizational sciences for a timely topic which has received little attention.

Fermilab is building a Vertical Cavity Test Facility (VCTF) to provide for R and D and pre-production testing of bare 9-cell, 1.3-GHz superconducting RF (SRF) cavities for the International Linear Collider (ILC) program. This facility is located in the existing Industrial Building 1 (IB1) where the Magnet Test Facility (MTF) also resides. Helium and nitrogen cryogenics are shared between the VCTF and MTF including the existing 1500-W at 4.5-K helium refrigerator with vacuum pumping for super-fluid operation (125-W capacity at 2-K). The VCTF is being constructed in multiple phases. The first phase is scheduled for completion in mid 2007, and includes modifications to the IB1 cryogenic infrastructure to allow helium cooling to be directed to either the VCTF or MTF as scheduling demands require. At this stage, the VCTF consists of one Vertical Test Stand (VTS) cryostat for the testing of one cavity in a 2-K helium bath. Planning is underway to provide a total of three Vertical Test Stands at VCTF, each capable of accommodating two cavities. Cryogenic infrastructure improvements necessary to support these additional VCTF test stands include a dedicated ambient temperature vacuum pump, a new helium purification skid, and the addition of helium gas storage. This paper describes the system design and initial cryogenic operation results for the first VCTF phase, and outlines future cryogenic infrastructure upgrade plans for expanding to three Vertical Test Stands

Redesign of the low energy section of the Fermilab linac to improve beam brightness

International Nuclear Information System (INIS)

Schmidt, C.; Noble, R.; Palkovic, J.; Mills, F.E.

1988-10-01

The critical parameters which limit the luminosity of the Fermilab Tevatron Collider are the beam emittances, both longitudinal and transverse, at each stage in the acceleration sequence. Improvements to reduce invariant emittance growth at earlier acceleration stages necessarily encourage improvements in all downstream stages. Recent advances in linac technology should permit a significant increase in the beam brightness of the Fermilab linac. A redesign of the low energy section of the linac is envisioned to include a circular aperture H/sup /minus// source, a short 30-keV transport line (solenoids, Gabor lenses or einzel lenses) for matching to a radio frequency quadrupole linac (RFQ), and injection at approximately 2 MeV into a new 200 MHz Alvarez linac tank for acceleration to 10 MeV. 9 refs., 1 fig

Global warming phenomena are increasingly serious, the El Niño and La Niña continue to occur repeatedly, causing the irregular drought and flood problem repeatedly. Mountain form of Taiwan is steep and storage ability of rainwater is insufficient to supply the livelihood of people and usage of industry which need to rely on rainwater reservoir. Thus, to ensure the water supply and self-reliance energy supply, one of ways to keep water resource is to build reservoir. Nevertheless, Taiwan is located on Pacific seismic belt; additionally, geological conditions are not fine, over-developed in the hills lead to more natural disasters in the future. Thus, strong shakes and typhoons which caused a degree of severe landslides around dam lead to reduce catchment of dam to result in affecting the safety of dam. Otherwise, the cracks and rusts in dam, induced by the defects of material, bad construction and seismic excitation respectively, thus, the mechanics phenomena of dam and its affiliated structures with crack are probing into the cause of stress concentration, induced high crack increase rate, affect the safety and usage of dam. This research is aimed at the safety evaluation technique of dam and its affiliated structures to develop three dimensional digital image correlation techniques for monitoring the safety of dam and its affiliated structures. Namely, developing the unmanned mobile on two axis of digital image correlation method is to detect the digital images from geometric scanning techniques for dam structure. This developed technique combined with Unmanned Aerial Vehicle (UAV) to develop the near filed scanning and monitoring techniques for local deformation and cracks on dam and its affiliated structures.

The SeaQuest Spectrometer at Fermilab

Energy Technology Data Exchange (ETDEWEB)

Aidala, C.A.; et al.

2017-06-29

The SeaQuest spectrometer at Fermilab was designed to detect oppositely-charged pairs of muons (dimuons) produced by interactions between a 120 GeV proton beam and liquid hydrogen, liquid deuterium and solid nuclear targets. The primary physics program uses the Drell-Yan process to probe antiquark distributions in the target nucleon. The spectrometer consists of a target system, two dipole magnets and four detector stations. The upstream magnet is a closed-aperture solid iron magnet which also serves as the beam dump, while the second magnet is an open aperture magnet. Each of the detector stations consists of scintillator hodoscopes and a high-resolution tracking device. The FPGA-based trigger compares the hodoscope signals to a set of pre-programmed roads to determine if the event contains oppositely-signed, high-mass muon pairs.

Proton Beam Intensity Upgrades for the Neutrino Program at Fermilab

Energy Technology Data Exchange (ETDEWEB)

Bhat, C. M. [Fermilab

2016-12-15

Fermilab is committed to upgrading its accelerator complex towards the intensity frontier to pursue HEP research in the neutrino sector and beyond. The upgrade has two steps: 1) the Proton Improvement Plan (PIP), which is underway, has its primary goal to start providing 700 kW beam power on NOvA target by the end of 2017 and 2) the foreseen PIP–II will replace the existing LINAC, a 400 MeV injector to the Booster, by an 800 MeV superconducting LINAC by the middle of next decade, with output beam intensity from the Booster increased significantly and the beam power on the NOvA target increased to <1.2 MW. In any case, the Fermilab Booster is going to play a very significant role for the next two decades. In this context, we have recently developed and commissioned an innovative beam injection scheme for the Booster called "early injection scheme". This scheme is already in operation and has a potential to increase the Booster beam intensity from the PIP design goal by a considerable amount with a reduced beam emittance and beam loss. In this paper, we will present results from our experience from the new scheme in operation, current status and future plans.

The Short-Baseline Neutrino (SBN) physics program at Fermilab and Neutrino Platform (NP) at CERN are part of the international Neutrino Program leading to the development of Long-Baseline Neutrino Facility/Deep Underground Neutrino Experiment (LBNF/DUNE) science project. The SBN program consisting of three Liquid Argon Time Projection Chamber (LAr-TPC) detectors positioned along the Booster Neutrino Beam (BNB) at Fermilab includes an existing detector known as MicroBooNE (170-ton LAr-TPC) plus two new experiments known as SBN’s Near Detector (SBND, ~260 tons) and SBN’s Far Detector (SBN-FD, ~760 tons). All three detectors have distinctly different design of their cryostats thus defining specific requirements for the cryogenic systems. Fermilab has already built two new facilities to house SBND and SBN-FD detectors. The cryogenic systems for these detectors are in various stages of design and construction with CERN and Fermilab being responsible for delivery of specific sub-systems. This contribution presents specific design requirements and typical implementation solutions for each sub-system of the SBND and SBN-FD cryogenic systems.

The experiment might commence data-taking as early as 1999. In addition to programmatic charm physics such as spectroscopy, lifetimes, and QCD tests, it will have significant new-physics reach in the areas of CP violation, flavor-changing neutral-current and lepton-number-violating decays, and D o bar D bar o mixing, and should observe direct CP violation in Cabibbo-suppressed D decays if it occurs at the level predicted by the Standard Model

1985-06-01

Fermilab's Advanced Computer Program is constructing a powerful 128 node multi-microprocessor system for data analysis in high-energy physics. The system will use commercial 32-bit microprocessors programmed in Fortran-77. Extensive software supports easy migration of user applications from a uniprocessor environment to the multiprocessor and provides sophisticated program development, debugging, and error handling and recovery tools. This system is designed to be readily copied, providing computing cost effectiveness of below $2200 per VAX 11/780 equivalent. The low cost, commercial availability, compatibility with off-line analysis programs, and high data bandwidths (up to 160 MByte/sec) make the system an ideal choice for applications to on-line triggers as well as an offline data processor

The High Energy Physics (HEP) group at Prairie View A ampersand M University is a collaborator with Fermi National Accelerator Laboratory (Fermilab), and the universities listed below. The purpose of this collaboration is to contribute to the understanding of heavy quark hadroproduction. Our efforts began in the early 1980's at Fermilab with the study of the charmonium states, J/ψ and χ, (DE-FG-86ER-40297) and presently with the continued studies of the charmonium system and direct photon production (Fermilab experiment E705) and new studies on bottom production (Fermilab experiment E771) in the High Intensity Laboratory (Proton-West Area) of Fermilab. The Prairie View group will, as a part of their task, be directly responsible for a major part of the PWC system upgrade by developing the electronics for the readouts of the PWC pad chambers. Six in all, these chambers, are a part of new multilevel triggering scheme and represents a departure from the triggering methodology of the previous trigger processors in earlier experiments. The Prairie View group is also involved with the Bottom Collider Detector (BCD) Collaboration which is proposing to study bottom production at the Fermilab Collider and at the Superconducting Super Collider (SSC)

Understanding Group/Party Affiliation Using Social Networks and Agent-Based Modeling

Science.gov (United States)

Campbell, Kenyth

2012-01-01

The dynamics of group affiliation and group dispersion is a concept that is most often studied in order for political candidates to better understand the most efficient way to conduct their campaigns. While political campaigning in the United States is a very hot topic that most politicians analyze and study, the concept of group/party affiliation presents its own area of study that producers very interesting results. One tool for examining party affiliation on a large scale is agent-based modeling (ABM), a paradigm in the modeling and simulation (M&S) field perfectly suited for aggregating individual behaviors to observe large swaths of a population. For this study agent based modeling was used in order to look at a community of agents and determine what factors can affect the group/party affiliation patterns that are present. In the agent-based model that was used for this experiment many factors were present but two main factors were used to determine the results. The results of this study show that it is possible to use agent-based modeling to explore group/party affiliation and construct a model that can mimic real world events. More importantly, the model in the study allows for the results found in a smaller community to be translated into larger experiments to determine if the results will remain present on a much larger scale.

Y2K affiliation, immediate pedestrian density, and helping responses to lost letters.

Bridges, F S; Thompson, P C

2001-06-01

Of 75 letters "lost" in Florida, 41 were returned in the mail (the helpful response). Immediate pedestrian density was significantly related to nonhelping responses. The greater the number of subjects passing by a lost letter, the less likely any one of them would respond to it. The rates of return did vary with the addressees' affiliations. Returned responses for the affiliates, Y2K Arkbuilders and the Believers of God's Judgement Against Homosexuals: Y2K Millennium Bug, were substantially lower than for the affiliate, Y2K Computer Repair & Programming, Inc. Returns for the Believers of God's Judgement Against Homosexuals: Y2K Millennium Bug affiliate were significantly lower than for the Y2K Arkbuilders affiliate. Variables such as sex, race, and estimated age of subjects were not associated with helping to return a lost letter. The rate of return of lost letters is not the only important measure to be examined in studies using lost letters.

The discovery of the b quark at Fermilab in 1977: The experiment coordinator's story

International Nuclear Information System (INIS)

Yoh, J.

1997-12-01

I present the history of the discovery of the Upsilon (Υ) particle (the first member of the b-quark family to be observed) at Fermilab in 1977 by the CFS (Columbia-Fermilab-Stony Brook collaboration) E288 experiment headed by Leon Lederman. We found the first evidence of the Υ in November 1976 in an early phase of E288. The subsequent discovery in the spring of 1977 resulted from an upgraded E288 the μμII phase, optimized for dimuons, with about 100 times the sensitivity of the previous investigatory dimuon phase (which had been optimized for dielectrons).

The Discovery of the b Quark at Fermilab in 1977: The Experiment Coordinator's Story

Science.gov (United States)

Yoh, J.

1997-12-01

I present the history of the discovery of the Upsilon ({Upsilon}) particle (the first member of the b-quark family to be observed) at Fermilab in 1977 by the CFS (Columbia-Fermilab-Stony Brook collaboration) E288 experiment headed by Leon Lederman. We found the first evidence of the {Upsilon} in November 1976 in an early phase of E288. The subsequent discovery in the spring of 1977 resulted from an upgraded E288 the {mu}{mu}II phase, optimized for dimuons, with about 100 times the sensitivity of the previous investigatory dimuon phase (which had been optimized for dielectrons). The events leading to the discovery, the planning of {mu}{mu}II and the running, including a misadventure (the infamous Shunt Fire of May 1977), are described. Some discussions of the aftermath, a summary, and an acknowledgement list end this brief historical note.

The family caregivers of people with mental illness may internalize the public stereotypes into the affiliate stigma (i.e., the self-stigma of family members). This study aimed to compare the affiliate stigma across schizophrenia, bipolar disorder, and major depressive disorder, and to investigate potential factors associated with affiliate stigma. Each caregiver of family members with schizophrenia (n = 215), bipolar disorder (n = 85), and major depressive disorder (n = 159) completed the Affiliate Stigma Scale, Rosenberg Self-Esteem Scale, Caregiver Burden Inventory, Taiwanese Depression Questionnaire, and Beck Anxiety Inventory. After controlling for potential confounders, the hierarchical regression models showed that caregivers of a family member with schizophrenia had a higher level of affiliate stigma than those of bipolar disorder (β = -0.109; p stigma. The affiliate stigma of caregivers is associated with their self-esteem, caregiver burden, and by the diagnosis.

Some recent results from a two-arm calorimeter experiment performed at Fermilab are presented. The properties of high P/sub t/ jets produced in hydrogen from incident pions and protons were studied. These studies lead to several important results: the high P/sub t/ jet events observed are produced by parton--parton (quark or gluon) scattering, and therefore: an effective parton structure function for the pion and the internal transverse momentum of these partons could be measured. 16 references

Political party affiliation, political ideology and mortality.

Science.gov (United States)

Pabayo, Roman; Kawachi, Ichiro; Muennig, Peter

2015-05-01

Ecological and cross-sectional studies have indicated that conservative political ideology is associated with better health. Longitudinal analyses of mortality are needed because subjective assessments of ideology may confound subjective assessments of health, particularly in cross-sectional analyses. Data were derived from the 2008 General Social Survey-National Death Index data set. Cox proportional analysis models were used to determine whether political party affiliation or political ideology was associated with time to death. Also, we attempted to identify whether self-reported happiness and self-rated health acted as mediators between political beliefs and time to death. In this analysis of 32,830 participants and a total follow-up time of 498,845 person-years, we find that political party affiliation and political ideology are associated with mortality. However, with the exception of independents (adjusted HR (AHR)=0.93, 95% CI 0.90 to 0.97), political party differences are explained by the participants' underlying sociodemographic characteristics. With respect to ideology, conservatives (AHR=1.06, 95% CI 1.01 to 1.12) and moderates (AHR=1.06, 95% CI 1.01 to 1.11) are at greater risk for mortality during follow-up than liberals. Political party affiliation and political ideology appear to be different predictors of mortality. Published by the BMJ Publishing Group Limited.

Siberian snakes for the Fermilab Main Injector

International Nuclear Information System (INIS)

Anferov, V.A.; Baiod, R.; Courant, E.D.

1993-01-01

Appropriate Siberian snakes were designed to maintain the proton beam polarization during acceleration in the Fermilab Main Injector from 8 to 150 GeV. Various snake designs were investigated to find one fitting into the 14 m straight section spaces with the required spin rotation axis and the minimum orbit excursion. The authors studied both cold and warm discrete magnet snakes as well as warm snakes with helical magnets. For the warm discrete magnet snake, obtaining small orbit excursions required a nearly longitudinal snake axis, while axes near ±45 degrees are needed when using two snakes in a ring. The authors found acceptable snakes either by using superconducting magnets or by using warm magnets with a helical dipole field

Abort kicker power supply systems at Fermilab

International Nuclear Information System (INIS)

Krafczyk, G.; Dugan, G.; Harrison, M.; Koepke, K.; Tilles, E.

1985-01-01

Over the past several years, Fermilab has been operating with a single turn proton abort system in both the superconducting Tevatron and the conventional Main Ring. The abort kicker power supply for this system discharges a lumped capacitance into the inductive magnet load, causing the beam to enter the abort channel. A unique feature of this design is the high voltage, high current diode assembly used to clip the recharge of the capacitor bank. This allows the current to decay slowly with the L/R time constant of the magnet and diode series combination. Special attention will be given to the diode characteristics needed for this passive switching element. Operational experience and proposed upgrades will be given for the two operational systems

Numerically controlled oscillator for the Fermilab Booster

International Nuclear Information System (INIS)

Crisp, J.L.; Ducar, R.J.

1989-01-01

In order to improve the stability of the Fermilab Booster low level rf system, a numerically controlled oscillator system is being constructed. Although the system has not been implemented to date, the design is outlined in this paper. The heart of the new system consists of a numerically synthesized frequency generator manufactured by the Sciteq Company. The 3 GHz/sec rate and 30 to 53 MHz range of the Booster frequency program required the design of a CAMAC based, fast-cycling (1 MHz), 65K x 32 bit, digital function generator. A 1 MHz digital adder and 12 bit analog to digital converter will be used to correct small program errors by phase locking the oscillator to the beam. 6 refs., 1 fig

The New Muon g-2 Experiment at Fermilab

Energy Technology Data Exchange (ETDEWEB)

Grange, Joseph [Argonne

2015-01-13

Precision measurements of fundamental quantities have played a key role in pointing the way forward in developing our understanding of the universe. Though the enormously successful Standard Model (SM) describes the breadth of both historical and modern experimental particle physics data, it is necessarily incomplete. The muon $g-2$ experiment executed at Brookhaven concluded in 2001 and measured a discrepancy of more than three standard deviations compared to the Standard Model calculation. Arguably, this remains the strongest hint of physics beyond the SM. A new initiative at Fermilab is under construction to improve the experimental accuracy four-fold. The current status is presented here.

1994-07-01

The superconducting Tevatron accelerator at Fermilab has reached its eleventh year of operation since being commissioned in 1983. Last summer, four significant upgrades to the cryogenic system became operational which allow Tevatron operation at higher energy. This came after many years of R ampersand D, power testing in sectors (one sixth) of the Tevatron, and final system installation. The improvements include the addition of cold helium vapor compressors, supporting hardware for subatmospheric operation, a new satellite refrigerator control system, and a higher capacity central helium liquefier. A description of each cryogenic upgrade, commissioning experience, and attempts to increase the energy of the Tevatron are presented

Grigoriev, Maxim; Fermilab; Cottrell, Les; Logg, Connie; SLAC

2004-01-01

Large, distributed High Energy Physics (HEP) collaborations, such as D0, CDF and US-CMS, depend on stable and robust network paths between major world research centres. The evolving emphasis on data and compute Grids increases the reliance on network performance. Fermilab's experimental groups and network support personnel identified a critical need for WAN monitoring to ensure the quality and efficient utilization of such network paths. This has led to the development of the Network Monitoring system we will present in this paper. The system evolved from the IEPM-BW project, started at SLAC three years ago. At Fermilab this system has developed into a fully functional infrastructure with bi-directional active network probes and path characterizations. It is based on the Iperf achievable throughput tool, Ping and Synack to test ICMP/TCP connectivity. It uses Pipechar and Traceroute to test, compare and report hop-by-hop network path characterization. It also measures real file transfer performance by BBFTP and GridFTP. The Monitoring system has an extensive web-interface and all the data is available through standalone SOAP web services or by a MonaLISA client. Also in this paper we will present a case study of network path asymmetry and abnormal performance between FNAL and SDSC, which was discovered and resolved by utilizing the Network Monitoring system

Need for Affiliation as a Motivational Add-On for Leadership Behaviors and Managerial Success.

Science.gov (United States)

Steinmann, Barbara; Ötting, Sonja K; Maier, Günter W

2016-01-01

In a sample of 70 leader-follower dyads, this study examines the separate and interactive effects of the leaders' implicit needs for power, achievement, and affiliation on leadership behaviors and outcomes. Results show that whereas the need for achievement was marginally associated with follower-rated passive leadership, the need for affiliation was significantly related to ratings of the leaders' concern for the needs of their followers. Analyzing motive combinations in terms of interactive effects and accounting for the growing evidence on the value of affiliative concerns in leadership, we assumed the need for affiliation would channel the interplay among the needs for power and achievement in such a way that the leaders would become more effective in leading others. As expected, based on high need for achievement, the followers were more satisfied with their jobs and with their leaders and perceived more transformational leadership behavior if power-motivated leaders equally had a high need for affiliation. Moreover, the leaders indicated higher career success when this was the case. However, in indicators of followers' performance, the three-way interaction among the needs for power, achievement, and affiliation did not account for additional variance.

Oxytocin and social affiliation in humans.

Science.gov (United States)

Feldman, Ruth

2012-03-01

A conceptual model detailing the process of bio-behavioral synchrony between the online physiological and behavioral responses of attachment partners during social contact is presented as a theoretical and empirical framework for the study of affiliative bonds. Guided by an ethological behavior-based approach, we suggest that micro-level social behaviors in the gaze, vocal, affective, and touch modalities are dynamically integrated with online physiological processes and hormonal response to create dyad-specific affiliations. Studies across multiple attachments throughout life are presented and demonstrate that the extended oxytocin (OT) system provides the neurohormonal substrate for parental, romantic, and filial attachment in humans; that the three prototypes of affiliation are expressed in similar constellations of social behavior; and that OT is stable over time within individuals, is mutually-influencing among partners, and that mechanisms of cross-generation and inter-couple transmission relate to coordinated social behavior. Research showing links between peripheral and genetic markers of OT with concurrent parenting and memories of parental care; between administration of OT to parent and infant's physiological readiness for social engagement; and between neuropeptides and the online synchrony of maternal and paternal brain response in social-cognitive and empathy networks support the hypothesis that human attachment develops within the matrix of biological attunement and close behavioral synchrony. The findings have conceptual implications for the study of inter-subjectivity as well as translational implications for the treatment of social disorders originating in early childhood, such as autism spectrum disorders, or those associated with disruptions to early bonding, such as postpartum depression or child abuse and neglect.

Competing Claims: Religious Affiliation and African Americans' Intolerance of Homosexuals.

Science.gov (United States)

Ledet, Richard

2017-01-01

Literature on religion and political intolerance indicates competing expectations about how Black Protestant church affiliation affects African Americans' attitudes about civil liberties. On the one hand, Black Protestant theology emphasizes personal freedom and social justice, factors generally linked to more tolerant attitudes. On the other hand, Black Protestants tend to be conservative on family and social issues, factors often linked to intolerance of gays and lesbians. Data from the General Social Survey are used to examine the influence of religious group identification, as well as other relevant aspects of religiosity, on political intolerance among African Americans. Results indicate that although other aspects of religion (beliefs and behaviors) help explain variation in political intolerance, Black Protestant church affiliation has no relationship with attitudes about the civil liberties of homosexuals. However, additional tests show that Black Protestant church affiliation significantly predicts intolerance of other target groups (atheists and racists).

FERMILAB: More antiprotons

International Nuclear Information System (INIS)

Visnjic, Vladimir

1993-01-01

The excellent performance of the Fermilab antiproton complex during the recent Collider run and its future potential are the cumulative result of many improvements over the past few years, ranging from major projects like upgrading the stack-tail stochastic cooling system in the Accumulator to minor improvements like automating tuning procedures. The antiprotons are created when the 120 GeV proton beam from the Main Ring hits the target. A good target should have high yield of antiprotons, should not melt, and should not crack due to shock waves. The old copper target has been replaced by a new one made of nickel. The yield into the Debuncher is 2 x 10 -5 antiprotons/proton. While this is only marginally better than for copper, the nickel target has high melting point energy (1070 J/g) and a low rate of increase in pressure with deposited energy, making it the target of choice for the proton intensities expected in the Main Injector era (June, page 10). Of the broad spectrum of all kinds of secondaries, only a tiny fraction are 8 GeV antiprotons. The 8 GeV negative charge secondaries are bent through 3° by a new pulsed magnet. Instead of a 200-turn magnet with coils separated by epoxy as in the past, the new magnet has one turn carrying 45.5 kA of current. This single turn pulsed magnet uses radiation hard ceramic and is much more robust

The Fermilab computing farms in 2000

International Nuclear Information System (INIS)

Troy Dawson

2001-01-01

The year 2000 was a year of evolutionary change for the Fermilab computer farms. Additional compute capacity was acquired by the addition of PCs for the CDF, D0 and CMS farms. This was done in preparation for Run 2 production and for CMS Monte Carlo production. Additional I/O capacity was added for all the farms. This continues the trend to standardize the I/O systems on the SGI O2x00 architecture. Strong authentication was installed on the CDF and D0 farms. The farms continue to provide large CPU resources for experiments and those users whose calculations benefit from large CPU/low IO resources. The user community will change in 2001 now that the 1999 fixed-target experiments have almost finished processing and Run 2, SDSS, miniBooNE, MINOS, BTeV, and other future experiments and projects will be the major users in the future

Experiments at Fermilab require an ongoing program of development for high speed, distributed data acquisition systems. The physics program at the lab has recently started the operation of a Fixed Target run in which experiments are running the DART[1] data acquisition system. The CDF and D experiments are preparing for the start of the next Collider run in mid 2000. Each will read out on the order of 1 million detector channels. In parallel, future experiments such as BTeV R ampersand D and Minos have already started prototype and test beam work. BTeV in particular has challenging data acquisition system requirements with an input rate of 1500 Gbytes/sec into Level 1 buffers and a logging rate of 200 Mbytes/sec. This paper will present a general overview of these data acquisition systems on three fronts those currently in use, those to be deployed for the Collider Run in 2000, and those proposed for future experiments.

The E731 experiment at Fermilab has searched for ''direct'' CP violation in K 0 → ππ, which is parametrized by var-epsilon '/var-epsilon. For the first time, in 20% of the data set, all four modes of the K L,S → π + π - (π 0 π 0 ) were collected simultaneously, providing a great check on the systematic uncertainty. The result is Re(var-epsilon '/var-epsilon) = -0.0004 ± 0.0014 (stat) ± 0.0006(syst), which provides no evidence for ''direct'' CP violation. The CPT symmetry has also been tested by measuring the phase difference Δφ = φ 00 - φ ± between the two CP violating parameters η 00 and η ± . We fine Δφ = -0.3 degrees ± 2.4 degree(stat) ± 1.2 degree(syst). Using this together with the world average φ ± , we fine that the phase of the K 0 -bar K 0 mixing parameter var-epsilon is 44.5 degree ± 1.5 degree. Both of these results agree well with the predictions of CPT symmetry. 17 refs., 10 figs

Promoting Physical Activity With Group Pictures. Affiliation-Based Visual Communication for High-Risk Populations.

Reifegerste, Doreen; Rossmann, Constanze

2017-02-01

Past research in social and health psychology has shown that affiliation motivation is associated with health behavior, especially for high-risk populations, suggesting that targeting this motivation could be a promising strategy to promote physical activity. However, the effects that affiliation appeals (e.g., pictures depicting companionship during physical activities) and accompanying slogans have on motivating physical activity have been largely unexplored. Hence, our two studies experimentally tested the effects of exposure to affiliation-based pictures for overweight or less active people, as well as the moderating effect of affiliation motivation. The results of these two studies give some indication that group pictures (with or without an accompanying slogan) can be an effective strategy to improve high-risk populations' attitudes, self-efficacy, and intentions to engage in physical activity. Affiliation motivation as a personality trait did not interact with these effects, but was positively associated with attitudes, independent of the group picture effect.

Cross-Cultural Sex Differences in Post-Conflict Affiliation following Sports Matches.

The nature of ancestral human social structure and the circumstances in which men or women tend to be more cooperative are subjects of intense debate. The male warrior hypothesis proposes that success in intergroup contests has been vital in human evolution and that men therefore must engage in maximally effective intragroup cooperation [1-3]. Post-conflict affiliation between opponents is further proposed to facilitate future cooperation [4], which has been demonstrated in non-human primates [5] and humans [6]. The sex that invests more in post-conflict affiliation, therefore, should cooperate more. Supportive evidence comes from chimpanzees, a close genetic relative to humans that also engages in male intergroup aggression [7]. Here we apply this principle to humans by testing the hypothesis that among members of a large community, following a conflict, males are predisposed to be more ready than females to repair their relationship via friendly contact. We took high-level sports matches as a proxy for intragroup conflict, because they occur within a large organization and constitute semi-naturalistic, standardized, aggressive, and intense confrontations. Duration or frequency of peaceful physical contacts served as the measure of post-conflict affiliation because they are strongly associated with pro-social intentions [8, 9]. Across tennis, table tennis, badminton, and boxing, with participants from 44 countries, duration of post-conflict affiliation was longer for males than females. Our results indicate that unrelated human males are more predisposed than females to invest in a behavior, post-conflict affiliation, that is expected to facilitate future intragroup cooperation.

Cahill, K.; Smedinghoff, J.

1992-01-01

The Fermilab accelerator operator workstation of choice is now the Digital VAX station running VMS and X-Window software. This new platform provides an easy to learn programming environment while support routines are expanding in number and power. The X-Window environment is exploited to provide remote consoles to users across long haul networks and to support multiple consoles on a single workstation. The integration of imaging systems, local datalogging, commercial and Physics community's software, and development facilities on the operator workstation adds functionality to the system. The locally engineered knob/pointer/keyboard interface solves the multiple keyboard and mouse problems of a multi-screen console. This paper will address these issues of Fermilab's accelerator operator workstations. (author)

Genetic and Environmental Influences on Affiliation with Deviant Peers during Adolescence and Early Adulthood

Adolescence and early adulthood is a time when peer groups become increasingly influential in the lives of young people. Youth exposed to deviant peers risk susceptibility to externalizing behaviors and related psychopathology. In addition to environmental correlates of deviant peer affiliation, a growing body of evidence suggests that affiliation with deviant peers is heritable. This study examined the magnitude of genetic and environmental influences on affiliation with deviant peers, chang...

The discovery of the b quark at Fermilab in 1977: The experiment coordinator`s story

Energy Technology Data Exchange (ETDEWEB)

Yoh, J.

1997-12-01

I present the history of the discovery of the Upsilon ({Upsilon}) particle (the first member of the b-quark family to be observed) at Fermilab in 1977 by the CFS (Columbia-Fermilab-Stony Brook collaboration) E288 experiment headed by Leon Lederman. We found the first evidence of the {Upsilon} in November 1976 in an early phase of E288. The subsequent discovery in the spring of 1977 resulted from an upgraded E288 the {mu}{mu}II phase, optimized for dimuons, with about 100 times the sensitivity of the previous investigatory dimuon phase (which had been optimized for dielectrons). The events leading to the discovery, the planning of {mu}{mu}II and the running, including a misadventure (the infamous Shunt Fire of May 1977), are described. Some discussions of the aftermath, a summary, and an acknowledgement list end this brief historical note.

From Environmental Connectedness to Sustainable Futures: Topophilia and Human Affiliation with Nature

Directory of Open Access Journals (Sweden)

Thomas Beery

2015-07-01

Full Text Available Human affiliation with nonhuman nature is an important dimension of environmental concern and support for pro-environmental attitudes. A significant theory of human connectedness with nature, the Biophilia Hypothesis, suggests that there exists a genetically based inclination for human affiliation with the biological world. Both support and challenge to the Biophilia Hypothesis are abundant in the literature of environmental psychology. One response that both challenges and builds upon the Biophilia Hypothesis is the Topophilia Hypothesis. The Topophilia Hypothesis has extended the ideas of biophilia to incorporate a broader conception of nonhuman nature and a co-evolutionary theory of genetic response and cultural learning. While the Topophilia Hypothesis is a new idea, it is built upon long-standing scholarship from humanistic geography and theories in human evolution. The Topophilia Hypothesis expands previous theory and provides a multidisciplinary consideration of how biological selection and cultural learning may have interacted during human evolution to promote adaptive mechanisms for human affiliation with nonhuman nature via specific place attachment. Support for this possible co-evolutionary foundation for place-based human affiliation with nonhuman nature is explored from multiple vantage points. We raise the question of whether this affiliation may have implications for multifunctional landscape management. Ultimately, we propose that nurturing potential topophilic tendencies may be a useful method to promote sustainable efforts at the local level with implications for the global.

2009-09-01

Accelerator R&D has played a crucial role in enabling scientific discovery in the past century and will continue to play this role in the years to come. In the U.S., the Office of High Energy Physics of DOE's Office of Science is developing a plan for national accelerator R&D stewardship. Fermilab undertakes accelerator research, design, and development focused on superconducting radio-frequency (RF), superconducting magnet, beam cooling, and high intensity proton technologies. In addition, the Lab pursues comprehensive integrated theoretical concepts and simulations of complete future facilities on both the energy and intensity frontiers. At present, Fermilab (1) supplies integrated design concept and technology development for a multi-MW proton source (Project X) to support world-leading programs in long baseline neutrino and rare processes experiments; (2) plays a leading role in the development of ionization cooling technologies required for muon storage ring facilities at the energy (multi-TeV Muon Collider) and intensity (Neutrino Factory) frontiers, and supplies integrated design concepts for these facilities; and (3) carries out a program of advanced accelerator R&D (AARD) in the field of high quality beam sources, and novel beam manipulation techniques.

1977-01-01

A control system for the Fermilab Master-Slave servo manipulator was developed. This new system offers a significant improvement in operational performance over the extant servo design with additional emphasis on simplicity of operation and maintainability. The servo manipulator is force-reflecting in each of the seven independent bilateral motions. Master force multiplication is automatically increased as the slave force is increased to its fifty pound capacity. The design incorporates triac control of the low inertia two-phase servomotors and makes extensive use of digital circuits in the servo loops. The manipulator is utilized in servicing radioactive beam-line targeting equipment

After about 40 years of operation the RF accelerating cavities in Fermilab Booster need an upgrade to improve their reliability and to increase the repetition rate in order to support a future experimental program. An increase in the repetition rate from 7 to 15 Hz entails increasing the power dissipation in the RF cavities, their ferrite loaded tuners, and HOM dampers. The increased duty factor requires careful modelling for the RF heating effects in the cavity. A multi-physic analysis investigating both the RF and thermal properties of Booster cavity under various operating conditions is presented in this paper.

The electrostatic particle-in-cell codeWARP is currently being expanded in order to study electron cloud effects on the dynamics of the beam in storage rings. Results for the Fermilab main injector (MI) show the existence of a threshold in the electron density beyond which there is rapid emittance growth. The Fermilab MI is being considered for an upgrade as part of the high intensity neutrino source (HINS) effort, which will result in a significant increasing of the bunch intensity relative to its present value, placing it in a regime where electron-cloud effects are expected to become important. Various results from the simulations using WARP are discussed here
