    An accelerator laboratory is presently under construction in Sofia at the Institute for Nuclear Research and Nuclear Energy. The laboratory will use a TR24 type of cyclotron, which provides a possibility to accelerate a proton beam with an energy of 15 to 24 MeV and current of up to 0.4 mA. An accelerator with such parameters allows to produce a large variety of radioisotopes for development of radiopharmaceuticals. The most common radioisotopes that can be produced with such a cyclotron are PET isotopes like: 11C, 13N, 15O, 18F, 124I, 64Cu, 68Ge/68Ga, and SPECT isotopes like: 123I, 111In, 67Ga, 57Co, 99mTc. Our aim is to use the cyclotron facility for research in the fields of radiopharmacy, radiochemistry, radiobiology, nuclear physics, materials sciences, applied research, new materials and for education in all these fields including nuclear energy. Presently we perform investigations in the fields of target design for production of radioisotopes, shielding and radioprotection, new ion sources etc.

    Full text: The Cyclotron U-150-II of Institute of Nuclear Physics was projected in middle of the last century for nuclear-physical researches in a scientific research institute of electro physical equipment in Leningrad. The Cyclotron can accelerate positive ions with beam energy of the protons 18 MeV, deuterons 20 MeV, alpha particles 40 MeV. Intensity of a beam a little some microampere. The building of a Cyclotron represents an impressive three-floor construction in volume of 2000 m 3 . The capital equipment, the high-frequency generator, sources of power supplies, vacuum pumps and other technological units are placed on the first and socle floors of a building. The second and third floors served for accommodation of scientific laboratories. A building of a Cyclotron has three experimental halls, where it was possible to carry out physical researches. They have divided from each other, and the main thing from the accelerator, concrete walls with the purpose of reduction of the big radiating background at the working accelerator, preventing realization of experiments. It provided also biological protection of the on duty personnel. The first some years of operation of the Cyclotron have revealed a line of lacks of this machine. For example, for change of energy of a beam of a Cyclotron it took 2-3 weeks. Also, for transition of acceleration of one particles to others it take same time. Time parameters of a beam were unstable. In 1968 reconstruction of the Cyclotron has been started that has allowed to bring in basic changes to parameters U-150-II. The time took on change of an operating mode of a Cyclotron was sharply reduced, and it was possible to reduce it till 10-20 hours, to improve the energy and time resolution of a beam many times over, to reduce angular straggling of particles in a beam. And, all this enormous amount of works was spent by forces of institute. In 70 th years the big development was received with works on radiating stability of materials

    The computer control system for the C-30 Medical Small Cyclotron, which is currently under construction at the Institute of Nuclear Studies will be presented. The features of this simple and secure system are briefly discussed. Some efforts have been done to make a conversational system easily understandable for operators. The keystone of the control system is an fibre optical link (wireless) between the cyclotron and the computer. The control system is based on the use of an extended configuration of the IBM PC/AT computer. A new system software is used to execute multitask hierarchical programs to control the cyclotron. The comercial adapters for control and data aquisition, connected with the fibre optic communication channels are used to transmit data and control codes. Two colour graphic CRT displays the ongoing status and function of each controlled units so that the operator can monitor the whole system conditions at a glance. The paper gives a general description of the programs which are executed on the computer. It also shows how the cyclotron is controlled by dedicated computer practically without special electronic equipment except of the hardware safety cutout switch. The cyclotron is protected against operating incidents and mistakes by a complex system of interlocks. (author)

    1982-01-01

    The system of cyclotron nuclear medicine consists of ''RI-production by using the cyclotron'', ''production of radio-pharmaceuticals labeled with RI'', ''positron tomography''. On the other hand, Ultra compact cyclotron (Baby cyclotron) itself, RI production technique and positron tomography have been rapidly developed and advanced. We think that these three functions must be balance in the development in order to spread this system into the routine work in the hospital. However, since the technology of the synthesis for the labeled compounds is not so developed so far, more advance can be strongly expected. In this report, construction of the cyclotron nuclear medicine, utility for the practical use of RI produced by using the cyclotron, technique of RI production, and the studies on automated and efficient productions of radio-pharmaceuticals labeled with short-lived positron emitters for medical diagnostic use are described.

    Radium Institute cyclotron MGC-20 is used since 1990. There are four cyclotrons of such type in Russia and four abroad: in Finland, in Hungary, in North Korea and in Egypt. The Radium institute cyclotron was used in different fields, such as radioisotope production, nuclear physics, physics and engineering. For ten years some improvements of the Radium Institute cyclotron operation have been made. Those are: creation of the automatic control system based on IBM PC, development of a new power supply for the ion source, creation of the deflector electronic protection from discharges, change of the main elements of the cyclotron with high induced radioactivity. Moreover we investigated the possibility of the negative ions acceleration at the MGC-20 cyclotron without ion source exchange. The maximum value of the proton beam current reached was about 30 μA for 10 MeV H - beam energy. To extract the proton beam from the cyclotron after the stripping foil we made an additional output beam line. It was used for determination of the horizontal and vertical emittance. A special device was constructed and used for measurements of emittance. The latter amounted 30 π mm mrad for horizontal direction and 16 π mm mrad for vertical direction

    Vera Ruiz, H.; Lambrecht, R.M.

    1999-01-01

    The IAEA recently concluded a worldwide survey of the cyclotrons used for radionuclide production. Most of the institutions responded to the questionnaire. The responses identified technical, utilisation and administrative information for 206 cyclotrons. Compiled data includes the characteristics, performance and popularity of each of the different commercial cyclotrons. Over 20 cyclotrons are scheduled for installation in 1998. The expansion in the number of cyclotron installations during the last decade was driven by the advent of advances in medical imaging instrumentation (namely, positron emission tomography (PET), and more recently by 511 KeV emission tomography); introduction of user friendly compact medical cyclotrons; and recent governmental decisions that permit reimbursement for cyclotron radiopharmaceutical studies by the government or insurance companies. The priorities for the production of clinical, commercial and research radionuclides were identified. The emphasis is on radionuclides used for medical diagnosis with SPET (e.g. 123 I, 201 Tl) and PET (e.g. 11 C, 13 N, 15 O, 18 F) radiopharmaceuticals, and for individualized patient radiation treatment planning (e.g. 64 Cu, 86 Y, 124 I) with PET. There is an emerging trend to advance the cyclotron as an alternative method to nuclear reactors for the production of neutron-rich radionuclides (e.g. 64 Cu, 103 Pd, 186 Re) needed for therapeutic applications.

    This study was aimed at establishing a list of radionuclides of interest for nuclear medicine that can be produced in a high-intensity and high-energy cyclotron. We have considered both therapeutic and positron emission tomography radionuclides that can be produced using a high-energy and a high-intensity cyclotron such as ARRONAX, which will be operating in Nantes (France) by the end of 2008. Novel radionuclides or radionuclides of current limited availability have been selected according to the following criteria: emission of positrons, low-energy beta or alpha particles, stable or short half-life daughters, half-life between 3 h and 10 days or generator-produced, favourable dosimetry, production from stable isotopes with reasonable cross sections. Three radionuclides appear well suited to targeted radionuclide therapy using beta ( 67 Cu, 47 Sc) or alpha ( 211 At) particles. Positron emitters allowing dosimetry studies prior to radionuclide therapy ( 64 Cu, 124 I, 44 Sc), or that can be generator-produced ( 82 Rb, 68 Ga) or providing the opportunity of a new imaging modality ( 44 Sc) are considered to have a great interest at short term whereas 86 Y, 52 Fe, 55 Co, 76 Br or 89 Zr are considered to have a potential interest at middle term. Several radionuclides not currently used in routine nuclear medicine or not available in sufficient amount for clinical research have been selected for future production. High-energy, high-intensity cyclotrons are necessary to produce some of the selected radionuclides and make possible future clinical developments in nuclear medicine. Associated with appropriate carriers, these radionuclides will respond to a maximum of unmet clinical needs. (orig.) 5

    This report contains descriptions of research programs carried out by Institute staff, as well as progress on new instrumentation during the period, April 1, 1990, to March 31, 1991. The K500 cyclotron and ECR source provided beam for 4140 hours during the period. The beam was actually available for experiments 1927.50 hours and 1110.50 hours was devoted to developing new beams and exploring cyclotron performance. A wide range of beams from protons to Xe with energies from 2.4 MeV/u to 60 MeV/U have been used in experiments. The highest total energy beam accelerated was 35 MeV/u 63 Cu. The ECR source, made a tremendous improvement in accelerator performance and reliability. Substantial amounts of beam time were devoted to investigations of hot nuclei, electron-positron, giant resonances, atomic effects of high velocity ion beams, astrophysics related reactions and proton and alpha bremsstrahlung. Scientific accomplishments included determination of the heat capacity of nuclei through new insight into the level densities and establishing a lower limit for electron positron resonances a factor of ten better than previous measurements. The proton spectrometer, constructed for studies of the Gamow-Teller interaction is complete, and initial physics measurements will be made in the next few months. All of the BaF 2 crystals have been delivered and acceptance tests are underway. A K=315 MDM spectrometer has been obtained from Oxford University and is scheduled for installation in Spring 1992, after removal of the K=150 Enge split pole spectrometer.

    With the acquisition of RDS-111 particle accelerator, the Institute of Nuclear Engineering in Rio de Janeiro city (IEN) operates a new cyclotron to produce 1 8F to obtain the fluorodeoxyglucose (FDG), a radiopharmaceutical used in positron emission tomography (PET), a technique well advanced which allows obtaining images with high resolution for diagnoses in medicine. To evaluate and detect the gamma exposure during 1 8F production, in the routine operation, i.e. current of 30 μA and the operating time 120 minutes, it was used a portable detector hyperpure germanium (HPGe) coupled to an electronic system for acquisition of 4096 data channels. To obtain a wide energy spectrum from 0.1 to 20 MeV were performed measurements with different gains of amplification. The energy average of gamma radiation, calculated from the energy spectra of gamma rays obtained, was 1.59 ± 0.05 MeV. Meanwhile, measurements were made with a MIR 7026 monitor and with thermoluminescent detectors (TLD) of LiF: Mg, Cu, P to calculate the dose equivalent rates H * (10) of the installation

    This report contains descriptions of research programs at the Institute, progress on construction of the K500 cyclotron, and descriptions of new experimental devices being built to take advantage of new beams that will be available. Several milestones were reached in construction of the new cyclotron during the period. In early summer, 1986, the magnet was completed with all trim coils and shimming iron in place. During July and August, the final field maps were made, which will be used for calculations of run parameters. In the spring, one rf amplifier was completed and tested over the full frequency and power range. Also in the spring, the computer control system successfully operated positioning controls and trim coil power supplies. Final assembly of the rf system including the dees, resonators and other 2 rf amplifiers is now underway. Initial attempts at getting beam are expected in September. The design of the ECR source was completed in the fall. A beam line configuration has been designed for the K500 cyclotron which will result initially in 3 lines, with a fourth to be added in 1988. With the eminent completion of the K500, there has been considerable instrumentation development. A 4π neutron calorimeter is under construction for heavy ion reaction studies, construction is beginning on a proton spectrometer for studies of Gamow-Teller matrix elements with the (d, 2 He) reaction, and several detector systems are being developed. During the year, the 88 inch cyclotron operated 4845 hours for research and beam development. Research programs in nuclear science scheduled 57% of the time. Atomic physics programs used 19% of the time, and a program in trace analysis scheduled 6%. An industrial testing laboratory used 18 hours. The remainder of the time was used for beam development, primarily for increasing the energy and/or intensity of heavy ion beams

    The Cyclotron Center of the Slovak Republic was established at the beginning of August 1999 - within the Slovak-Office of Standards, Metrology and Testing (SOSMT), in Bratislava, Slovak Republic. It will have two cyclotrons - a large heavy and light cyclotron DC-72, which will be constructed by the Joint Institute for Nuclear Research (JINR), Dubna, Russian Federation, and a small commercial light ion cyclotron IBA 18/9. The heavy ion source of the electron resonance type (DECRS-2M) will be used for low and medium energy experiments in physics. The small electron accelerator is planned for different applications, including improving the properties of plastics, increasing the resistance of cables to fire and temperature, the sterilization of medical disposables in the CC SR. The main purpose of the Cyclotron Center of the Slovak Republic (CC SR) is to catch the present approach and trends in the area of improving of inhabitants life and health quality using the progressive technology, which is introduced by bringing into practice of the physical equipment - accelerators, producing beams of high energy particles. Experts of nuclear physics and of the related branches have no experimental basis in Slovakia, as after dissolution of the former the Czech and Slovak Federal Republic all bigger nuclear equipment were left in the Czech Republic. The Slovak Republic is one of the European countries where cancer and cardiovascular diseases have a rapidly increasing tendency (the rate of new oncological cases is approximately 20,000/year at the population of 5 million inhabitants) - early diagnostics of population is necessary to be updated urgently. The Slovak Republic use a great part of electricity (about 60 %) from its own nuclear power stations and thus it is in need of education of rising generations of experts from different nuclear fields. The Government of the Slovak republic on June 18, 1996 approved the strategic aim of building up the Cyclotron Laboratory at the

    This Institute annual report for the period 1 April 1992--31 March 1993 covers a period which has seen the initial runs of three new spectrometers which constitute a major portion of the new detection capabilities developed for this facility. These devices are the Proton Spectrometer (PSP), the Mass Achromat Recoil Mass Spectrometer (MARS), and the Multipole dipole Multipole (MDM) Particle Spectrometer. These devices are now available to pursue the studies of Gamow Teller states, reactions of astrophysical interest, and giant resonance studies for which they were constructed, as well as for other experiments. A beam analysis system which will deliver high resolution beams to the MDM spectrometer is currently under construction. With the completion of these spectrometer projects, the facility emphasis is now focused on the development of the full capabilities of the K500 cyclotron and on the research program. During the report period, the ECR-K500 cyclotron combination operated 5,849 hours. Theoretical work reported in this document ranges from nuclear structure calculations using the IBM-2 model to calculations of kaon production and the in-medium properties of the rho and phi mesons, the latter as a probe of the QCD phase transition. Nuclear dynamics and exotic shapes and fragmentation modes of hot nuclei are also addressed. In atomic physics, new measurements of x-ray emission from highly ionized ions, of molecular dissociation and of surface interactions are reported.

    Radiopharmaceutical (RP) produced by cyclotrons are widely used for the in vivo diagnosis of various diseases such as cancer, cerebral vascular disorders and cardiac diseases. The nuclides used as RPs and their nuclear reactions, and the quantity of RPs supplied in Japan in the last five years are shown. These RPs are delivered to about 1,100 hospitals in Japan. Thallium-201 and iodine-123 showed very high growth rate. Recently, two new I-123 RPs, BMIPP and MIBG which are heart-imaging agents, have been supplied. It suggests that the quantity of I-123 will increase much more in future. The image diagnostic method using RPs is called in vivo nuclear medicine, and has become the indispensable means for medical institutions together with X-ray CT, nuclear magnetic resonance imaging and ultrasonic diagnosis. The RPs for in vivo diagnosis generally used at present are classified into those labeled with the RIs produced with cyclotrons and those labeled with Tc-99m formed by the decay of Mo-99. The quantity being used is overwhelmingly more in the latter, but the former shows the tendency of growth. The commercial production of cyclotron RIs for medical use, the chemical forms and the diagnostic purposes of the RPs using cyclotron RIs, and the state of use of the cyclotron-produced RPs are reported.

    The importance of radio frequency waves has been increasing in the area of nuclear fusion since they are indispensable for heating of plasma, etc. This report outlines radio frequency techniques used for nuclear fusion and describes the development of radio frequency systems (radio frequency plasma heating system and current drive system). Presently, in-depth studies are underway at various research institutes to achieve plasma heating by injection of radio frequency electric power. Three ranges of frequencies, ICRF (ion cyclotron range of frequency), LHRF (lower hybrid range of frequency) and ECRF (electron cyclotron range of frequency), are considered promissing for radio frequency heating. Candidate waves for plasma current driving include ECW (electron cyclotron wave), LHW (lower hybrid wave), MSW (magnetic sound wave), ICW (ion cyclotron wave) with minority component, and FW (fast wave). FW is the greatest in terms of current drive efficiency. In general, a radio frequency system for nuclear fusion consists of a radio frequency power source, transmission/matching circuit component and plasma connection component. (Nogami, K.)

    The production of radioisotopes to be used mainly for nuclear medicine and biology is studied with an AVF cyclotron in TIARA. A production method of no-carrier-added {sup 186}Re with the {sup 186}W(p,n){sup 186}Re reaction has been developed; this product may be used as a therapeutic agent in radioimmunotherapy due to the adequate nuclear and chemical properties. For the study of the function of plants using a positron-emitter two-dimensional imaging system, a simple method of producing the positron emitter {sup 18}F in water was developed by taking advantage of a highly-energetic {alpha} beam from the AVF cyclotron.

    The period 1 April 1992--31 March 1993 saw the initial runs of three new spectrometers, which constitute a major portion of the new detection capabilities developed for this facility. These devices are the Proton Spectrometer (PSP) (data from which are shown on the cover of this document), the Mass Achroniat Recoil Mass Spectrometer (MARS), and the Multipole Dipole Multipole (MDM) Particle Spectrometer. The ECR-K500 cyclotron combination operated 5,849 hours. The beam was on target 39% of this time. Studies of nuclear dynamics and nuclear thermodynamics using the neutron ball have come to fruition. A critical re-evaluation of the available data on the giant monopole resonance indicated that the incompressibility is not specified to a range smaller than 200--350 MeV by those data. New systematic experiments using the MDM spectrometer are now underway. The MEGA collaboration obtained the first data on the μ → eγ decay rate and determination of the Michel parameter in normal μ decay. Experiments appear to confirm the existence of monoenergetic pair peaks even for relatively low Z projectile -- Z target combinations. Studies of the (α,2α) knockout reaction indicate that this reaction may prove to be a valuable tool for determination of reaction rates of astrophysical interest. Theoretical work reported in this document ranges from nuclear structure calculations using the IBM-2 model to calculations of kaon production and the in-medium properties of the rho and phi mesons. Nuclear dynamics and exotic shapes and fragmentation modes of hot nuclei are also addressed. New measurements of x-ray emission from highly ionized ions, of molecular dissociation and of surface interactions are reported. The research is presented in nearly 50 brief summaries usually including data and references

    The main task of the Cyclotron Department is to operate the ATOMKI MGC-20E cyclotron, to support the research in different scientific fields and to use the accelerator in practice related applications. The Cyclotron Laboratory has been installed in a research institute so research is the most important task. Considering that some results of the basic research can be used in different routine applications, the second important task is to help developing systems for this reason. The capacity of the accelerator usually allows making routine applications to ensure the financial background for the service and for the development of the cyclotron. The cyclotron is applied directly for basic nuclear physics research and it indirectly helps the research in other fields via interdisciplinary studies. It is used in broad scale for different practical applications which have direct results in basic sciences in many cases therefore the classification sometimes is not simple. The irradiations at the cyclotron are dedicated to basic research in the field of nuclear structure and nuclear reaction studies and from other side to the so-called practical applications. The cyclotron has been in operation in ATOMKI since 1985. Since then the cyclotron has been reliably running with very short undesired breakdowns and it has been used for a wide range of research and application programs. This overview gives a short summary of the status of cyclotron operation and the practical applications and gives some indications on the future plans. (author)

    The IUCF cyclotrons ceased delivering particle beams for physics research and became dedicated medical proton beam accelerators in 1999. Removal of the beam lines and nuclear research facilities associated with the cyclotrons to make room for the new medical beam delivery systems was completed in October, 2000. A new achromatic beam line was completed, extending from the main stage cyclotron and ending at a temporary research platform. This beam line is being commissioned during ongoing applied research. The achromatic line will deliver 0.5 {mu}A of 205 MeV protons from which the treatment room technician may draw current at any time via fast switching, laminated magnets located at the entrances to the energy selection systems upstream of each of the treatment rooms. Three treatment rooms are planned, one containing two fixed horizontal lines and two gantry rooms. The cyclotrons will also support full time research in radiation effects, single event upset, radiation biology and pre-clinical research. This contribution describes the status of the medical construction project.

    Since 2003 the Institute of Nuclear Engineering in Rio de Janeiro city, Brazil, operates a new cyclotron, RDS-111, to produce {sup 18}F-Fluorodeoxyglucose to be used in nuclear medicine. Additionally, the IEN radioactive waste repository has been enlarged during the past last years, receiving a considerable amount of radioactive materials. Therefore, it became necessary to evaluate a possible increase of the environmental gamma exposure rates at the institute site due to the operation of the new accelerator and the enlargement of the institute waste repository as well. LiF:Mg,Cu,P, TLD-100H, and TL detectors were employed for environmental kerma rate evaluation and the results were compared with previous results obtained before the RDS-111 operation initialisation and the enlargement of IEN waste repository. No significant contribution for the enhancement of environmental gamma kerma rates was detected.

Tests were done demonstrating to be an instrument of great assistance in proton beam position along beam transport line and target port. Nowadays the XY-type current monitor has been widely used in {sup 18}F-FDG routine productions, employing irradiation system which were originally designed for productions on 18 MeV cyclotron accelerator only, however, applying the XY-type current monitor the target port may be exchanged between the 30 MeV and 18 MeV cyclotrons and the observed results are in perfect agreement with expected.

The directory contains technical, utilization and administrative information supplied to the IAEA as of October 1997. The directory was prepared through information collected by questionnaires sent to institutions that either have a cyclotron, or that were identified to be in the process of installation of a cyclotron. The directory contains 206 entries for cyclotrons operating in 34 Member States. The largest concentration of cyclotrons for radionuclide production are located in the United States of America (66), Japan (33) and Germany (22). The largest number of cyclotrons for a single country is the United States of America. The expansion in number of cyclotrons during the last decade has been driven by the advent of advances in medical imaging instrumentation (PET, SPET and more recently 511 KeV emission tomography); introduction of user friendly compact medical cyclotrons from several companies that manufacture cyclotrons; and recent decisions that 15 O-oxygen PET studies in Japan, and 18 F-FDG PET studies in Germany are eligible for reimbursement by government or insurance companies

    The problem of high efficient extraction (η ≥ 50%) from isochronous cyclotrons (with the exception of the stripping method) is not completely solved up to this day. This problem is specifically important, because these cyclotrons are being also applied in the production of medical radioisotopes, labeled pharmaceuticals as well as in neutron therapy (oncology), machine industry, agriculture (plant mutagenesis), etc. The aim of the proposed topic is to solve this problem on the AIC-144 isochronous cyclotron in the INP (Institute of Nuclear Physics). Lately, a beam of 20 MeV deuterons with an efficiency of ca. 15% was extracted from this cyclotron. (author). 25 refs, 14 figs

    Full text: The Institute of Nuclear Physics in Almaty is the only Kazakhstan institution with a significant activity at the national level in the field of physics of accelerators, their application and associated technology. Three accelerators of different type are being used in the Institute: high power electron beam accelerator, isochronous cyclotron and heavy ion electrostatic tandem. Electron beam accelerator ELV-4 - This high power machine is only electron beam irradiation facility of industrial scale in the Republic. It was produced by Budker Institute of Nuclear Physics, Novosibirsk, Russia and installed in Almaty in 1991 for development of radiation technology in Kazakhstan. The accelerator generates electron beams of following parameters: Energy range (MeV) 1.0-1.5; Max. beam power (kW) 40; Max. beam current (mA) 40. The machine is equipped with beam scanning system, extraction device with output window 980x75 mm 2 and chain conveyer for irradiated material supply. Tn the time being the accelerator is regularly used for radiation cross-linking technology and for sterilization. Cross-linking technology is the base of high quality roof material production for building industry. Raw ethylene-propylene rubber mixture is rolled as strip of 50 m length, 1 m width, 1 mm thickness and then irradiated by dose of about 120 kGy. The final product is waterproof flexible material, very stable in hard atmospheric conditions and non sensitive to sun UV radiation. Sterilization of medical materials and items is not traditional application of such low energy installations but due to uniqueness of this accelerator in Kazakhstan and high actuality of the task for the Republic this technology was developed in INP. Hermetically packed items (medical cotton , bandages, syringes, surgical gloves, small plastic bottles) with thickness less than penetration range of 1.5 MeV electrons are put at the conveyer as mono-layer and irradiated by sterilizing dose of 25 kGy.

    In the widespread use of some medical nuclear facilities, such as cyclotrons for isotope production, Life cycle analyzis, including decommissioning, was not taken into account. The structural materials of an accelerator and the concrete shielding of the bunker are activated by neutrons. This could yield a considerable volume of nuclear waste and needs radiation protection concern for occupational workers and the environment during some decennia. At the university of Brussels (WB) a prospective radiation protection and waste analyzis is being made for the later decommissioning of their cyclotron. Only few similar studies have been published. In Belgium future nuclear dismantling operations will be submitted to a radiation protection authorization procedure. Meanwhile the nuclear waste authorities insist on dismantling planning, including financial provisioning. An optimization exercise was made at the VUB-cyclotron, taking into account international trends to clearance levels for low level nuclear waste. Conceptual prevention opportunities e.g. selective material choice could be identified for future accelerator constructions. (author)

    An 18 GHz superconducting electron cyclotron resonance ion source is installed to increase beam currents and to extend the variety of ions especially for highly charged heavy ions which can be accelerated by cyclotrons of Research Center for Nuclear Physics (RCNP), Osaka University. The beam production developments of several ions from B to Xe have been already done [T. Yorita, K. Hatanaka, M. Fukuda, M. Kibayashi, S. Morinobu, H.Okamura, and A. Tamii, Rev. Sci. Instrum. 79, 02A311 (2008) and T. Yorita, K. Hatanaka, M. Fukuda, M. Kibayashi, S. Morinobu, H.Okamura, and A. Tamii, Rev. Sci. Instrum. 81, 02A332 (2010)] and the further studies for those beam extraction and its transport have been done in order to increase the beam current more. The plasma electrode, extraction electrode, and einzel lens are modified. Especially extraction electrode can be applied minus voltage for the beam extraction and it works well to improve the extracted beam current. The extraction voltage dependences of transmission and emittance also have been studied for beam current improvement which is injected into azimuthally varying field cyclotron at RCNP.

  1. Directory of cyclotrons used for radionuclide production in Member States [2006 update

    International Nuclear Information System (INIS)

    2006-10-01

    The present directory of cyclotron facilities used for the production of radionuclides in Member States is an update of the one compiled by the International Atomic Energy Agency (IAEA) in late 2001 and published in 2002. This directory was prepared through information collected by questionnaires that the IAEA sent to known institutions operating cyclotrons for radionuclide production. Technical as well as administrative data supplied to the IAEA as of November 2005 were taken into account. The directory is considered to include most of the cyclotrons of the world that are used at least partially for radionuclide production. There are 262 entries for cyclotrons operating in 39 Member States of the IAEA. This is an increase of 7% over the 246 reported in the 2002 cyclotron directory. This can be compared to the 350 or so cyclotrons believed to be presently operating in the world, which are involved in some aspects of radionuclide production. The increase has been in the number of cyclotrons in developed countries, but even more so in the developing countries. The increase in number during the last four years was driven by several factors, i.e. advent of advances in medical imaging, introduction of compact, user friendly medical cyclotron, and a recent decision that costs for 15 O-oxygen position emission tomography (PET) studies in Japan and 18 F-FDG PET studies in Germany and the United States of America are eligible for reimbursement by government or health insurance companies. There is no doubt that the fastest growing segment of the market is in the commercial distribution of FDG to local hospitals. The IAEA is promoting cyclotron technology as applied to nuclear medicine. Requests for cyclotron technology is steadily increasing; many developing Member States are interested in this technology. There is need to stimulate, build and maintain consulting capability in interested developing Member States. There are good reasons to believe that the number of cyclotron

    A cyclotron is a kind of particle accelerator that produces a beam of charged particles for the production of medical, industrial, and research radioisotopes. More than 30 cyclotrons are operated in Korea to produce 18F, an FDG synthesis at hospitals. A 30-MeV cyclotron was installed at ARTI (Advanced Radiation Technology Institute, KAERI) mainly for research regarding isotope production. In this study, we analyze and estimate the items of risk such as the problems in the main components of the cyclotron, the loss of radioactive materials, the leakage of coolant, and the malfunction of utilities, fres and earthquakes. To estimate the occurrence frequency in an accident risk assessment, five levels, i.e., Almost certain, Likely, Possible, Unlikely, and Rare, are applied. The accident consequence level is classified under four grades based on the annual permissible dose for radiation workers and the public in the nuclear safety law. The analysis of the accident effect is focused on the radioactive contamination caused by radioisotope leakage and radioactive material leakage of a ventilation filter due to a free. To analyze the risks, Occupation Safety and Health Acts is applied. In addition, action plans against an accident were prepared after a deep discussion among relevant researchers. In this acts, we will search for hazard and introduce the risk assessment for the research 30-MeV cyclotron facilities of ARTI.

    Sub-Saharan Africa is not a place where one will look first when radioactivity or nuclear physics is mentioned. Conducting forefront research at the international stage at US national facilities such as the Thomas Jefferson National Accelerator Facility in Virginia or the National Superconducting Cyclotron Facility/Facility for Rare Isotope Beams in Michigan does not point to Historically Black Colleges either. The two are actually intrinsically connected as my personal journey from my early exposure to radiation at the Curie Institute at the LeDantec Hospital in Senegal lead me to Hampton University. The former, through one of my uncles, catapulted me into a nuclear physics PhD while the latter houses the only nuclear physics program at an HBCU to date that has established itself as one of the premier programs in the nation. This talk will review the impact of Marie Curie in my life as a nuclear physicist.

    In-house cyclotron produced radioisotopes and positron computed tomography provide a unique technique which gives cross-sectional bodyimages of various kinds of physiological activities of living human body. Applications of the technique to clinical study might throw a new light on the etiologically unknown disorders of human central nervous system and etc. However, some difficulties should be settled before the establishment of this technique as an useful research and diagnostic tool. One of them was spatial resolution of positron computed tomography, and another was selection and development of really effective labeled compounds for the disease in question. A rotary positron emission computed tomography device was developed by our physicist team, and our chemist team developed various kinds of radiopharmaceuticals. Clinical applications of the technique started in our institute in November 1979, using the positron computed tomography machine named Positrologica I and the pharmaceuticals, 13sup( n h3, )11sup( C o and )18 F-2-fluoro-deoxy-glucose.

    In this paper the financial aspects of construction of the Cyclotron Centre of the Slovak Republic (CC SR) are analysed. This building represents the problems of exploitation of commodity deblocation of Russian Federation debt to Slovakia. The estimated expenses have risen from original planned 2 billion Slovak crowns to 6 billion Slovak crowns. Devices which should be part of centre - a cyclotron used for radiopharmaceuticals production for oncological purposes and a big cyclotron for industrial purposes, a centre of positron emissive tomography (PET), a laboratory of nano-technologies, a source of heavy ions - they indicates that the oncological institutes, departments of health service, of education, of economy, of defence, of environment, also Nuclear Regulatory Authority of Slovak Republic and Slovak Academy of Sciences should become the customers principally. Around 2.2 billion of Slovak crowns from deblocation have been spent for a construction of Cyclotron Centre of SR yet. The national budget has contributed by 95 million Slovak crowns; 90.5 million USD will be obtained from deblocation of Russian debt yet. IAEA has supported this centre by grant of almost 800 thousand USD. Budget of Cyclotron Centre of SR is still rising also because of rising of VAT from 10 percent to 19 percent. VAT will be paid also for goods imported within the framework of deblocation after integration of Slovak Republic to European Union; besides also 10 percent duty is paid. Project of CC SR has not passed the state expert opinion. Agreement for construction of Cyclotron Centre of SR was issued by State Health Institute of Bratislava, therefore it was confirmed also by the main hygienist of Slovak Republic

    The paper focuses on the role of institutional arrangements in developing a consensus in international nuclear cooperation. Institutional arrangements are defined as undertakings and activities by governments or private entities to facilitate the efficient and secure functioning of the nuclear fuel cycle. The first two sections of the paper explore the historical role of cooperative arrangements, suggest criteria for evaluating the usefulness of institutional arrangements, and review the status of the discussion of institutional arrangements in INFCE Working Groups as of December 1978. The final section of the paper, explores potential relationships between various institutional arrangements and suggests that certain areas such as, the standardization of nuclear practices, joint commercial and development undertakings, nuclear supply assurances, and the settlement of disputes may have broad application for several stages of the fuel cycle and merit further study

    This report is a compilation of the research activities and operations of the Research Center For Nuclear Physics (RCNP), Osaka University, during the period of the academic year 1994, April 1994 to March 1995. RCNP is the national laboratory for nuclear physics in Japan. The AVF cyclotron with K = 0.14GeV and the ring cyclotron with K = 0.4GeV and E P = 0.4GeV are the major user facilities at RCNP. They have been extensively used for studying nuclear nucleon-meson systems. All facilities are open for users from universities and research institutes in Japan as well as those in foreign countries. The research activities at the RCNP cyclotron laboratory include studies of nuclear interactions and nuclear potentials, spin isospin excitations and decays nuclear reaction dynamics and others. Studies of solid state and atomic physics and medical applications were carried out also at the cyclotron laboratory. New external ion sources have been instaled for the injector cyclotron. New extensions of the RCNP research activities are under progress. One is the possible use of the 8 GeV electron storage ring built at the synchrotron radiation laboratory SPring-8. It is located 100 Km west of Osaka. It is expected to start its operation in 1997. The Compton back-scattering of laser photons from the 8 GeV electron beam provides 1-3.5 GeV γ-rays, which are very promising for studying nuclear quark and meson systems. Other is the non-accelerator physics for ultra-rare nuclear processes at the new under ground laboratory 'Ohto Cosmo Observatory'. It is located 100 km south of Osaka. Neutrino studies by investigating double beta decays, dark matter studies by investigating nuclear responses to them, and studies of other weak processes are planned to be studied there. (J.P.N.)

    Presently Bulgaria has no research nuclear facility, neither a research reactor, nor an accelerator. With the new cyclotron laboratory in Sofia the Institute for Nuclear Research and Nuclear Energy at the Bulgarian Academy of Sciences will restart the experimental research program not only in the fi eld of nuclear physics, but also in many interdisciplinary fields related to nuclear physics. The cornerstone of the cyclotron laboratory is a cyclotron TR24, which provides a proton beam with a variable energy between 15 and 24 MeV and current of up to 0.4 mA. The TR24 accelerator allows for the production of a large variety of radioisotopes for medical applications and development of radiopharmaceuticals. The new cyclotron facility will be used for research in radiopharmacy, radiochemistry, radiobiology, nuclear physics, solid state physics, applied research, new materials and for education in all these fields including especially nuclear energy.

    Since 1974 a variable energy isochronous cyclotron (CV-28) is operating at Instituto de Engenharia Nuclear in Rio de Janeiro, with the main purpose of producing radioisotopes for medical diagnosis. To accomplish this, besides the conventional chemical laboratories and related facilities, hot chemistry laboratories with their specific equipment and remote handling devices had to be designed and constructed at this Institute, and are still being developed, due to a lack of engineering companies working in this field. Other equipment, intrinsically related to cyclotrons like high power density target holders, collimators etc. were also conceived and constructed. Among the produced raioisotopes, high purity gallium-67 and indium-111 have been periodically sent to hospitals and some efforts are still being made in order to improve and simplify the chemical processing as well as the operational procedures. Some work has also been devoted to the development and improvement of methods for the production of iodine-123, bromine-77 and thallium-201. (Author) [pt

    The operation of the Karlsruhe Isochronous Cyclotron in 1975 is briefly surveyed. The main reasons for a very short period for maintenance, repair and installation, and several additional efforts to improve the reliability of the accelerator installation, are discussed. The status and the results of several technical developments for the cyclotron are described: 1) the axial injection system; 2) computer aided cyclotron operation; 3) ion source development; 4) capacitive current measurement at the external beam; 5) new correction coils for the cyclotron; 6) improvement of the neutron time-of-flight spectrometer. As there is an increasing interest in using this type of accelerator for research in fields other than nuclear physics, it was felt appropriate to present short surveys on investigations at our cyclotron in 1975 in the fields of: 1) solid state physics; 2) engineering; 3) materials research; 4) nuclear medicine; 5) nuclear chemistry.

    2016-09-01

    The increase in use of radioisotopes for medical imaging has led to the development of new accelerator targetry and separation techniques for isotope production. For example, the development of longer-lived position emitting radionuclides has been explored to allow for nuclear imaging agents based on peptides, antibodies and nanoparticles. These isotopes (64Cu, 89Zr, 86Y) are typically produced via irradiation of solid targets on smaller cyclotrons (10-25 MeV) at academic or hospital based facilities. Recent research has further expanded the toolbox of PET tracers to include additional isotopes such as 52Mn, 55Co, 76Br and others. The smaller scale of these types of facilities can enable the straightforward involvement of students, thus adding to the next generation of nuclear science leaders. Research pertaining to development of robust and larger scale production technologies including solid target systems and remote systems for transport and purification of these isotopes has enabled both preclinical and clinical imaging research for many diseases. In particular, our group has focused on the use of radiolabeled antibodies for imaging of receptor expression in preclinical models and in a clinical trial of metastatic breast cancer patients.

    Egan, G.F.; Lagunas-Solar, M.C.

    1994-01-01

    The role of technetium-99m in nuclear medicine is well established with 80 per cent to 90 per cent of all nuclear medicine studies utilising this isotope. Technetium-99m is currently produced from nuclear reactors via production of the parent radionuclide molybdenum-99. The reactor production of 99m Tc has both significant financial and environmental costs, with unresolved problems in the areas of radioactive waste disposal and reactor decommissioning. Recent scientific publications have indicated that medical quality 99m Tc may be produced using cyclotrons without having the associated problems of waste disposal and decommissioning. Further scientific research is now required to demonstrate the feasibility of this cyclotron production technique. A collaboration between the Cyclotron and PET Centre, Austin Hospital, the National Medical Cyclotron, ANSTO, Sydney, and the Crocker Nuclear Laboratory, University of California, Davis, USA has been proposed. The general objective of the proposed collaboration is to acquire additional scientific data to evaluate the 99m Tc cyclotron production method and to determine the feasibility of cyclotron technology for Australian nuclear medicine. 16 refs., 2 tabs

    Simple and effective method of generation of tellurium nuclear isomers from irradiated on cyclotron metallic antimony is suggested. Basically this method consists in consideration of the big difference in volatilities of metallic forms of antimony, tin and tellurium. Heating of the tin-antimony alloy at 1200 K permits to separate about 90 % of produced quantity of 121m Te and 123m Te (in this case impurity of antimony radionuclides is not more than 1 % on activity) [ru

    Proton therapy is an effective method of treating oncologic diseases. In Russia, construction of several centers for proton and ion therapy is slated for the years to come. A proton therapy center in Dimitrovgrad will be the first. The Joint Institute for Nuclear Research (Russia) in collaboration with Ion Beam Application (IBA) (Belgium) has designed an C235-V3 medical proton cyclotron for this center. It outperforms previous versions of commercial IBA cyclotrons, which have already been installed in 11 oncologic hospital centers in different countries. Experimental and calculation data for the beam dynamics in the C235-V3 medical cyclotron are presented. Reasons for beam losses during acceleration are considered, the influence of the magnetic field radial component in the midplane of the accelerator and main resonances is studied, and a beam extraction system is designed. In 2011-2012 in Dubna, the cyclotron was mounted, its magnetic field was properly configured, acceleration conditions were optimized, and beam extraction tests were carried out after which it was supplied to Dimitrovgrad. In the C235-V3 cyclotron, an acceleration efficiency of 72% and an extraction efficiency of 62% have been achieved without diaphragming to form a vertical profile of the beam.

    As an upgrade project of the existing HI-13 tandem accelerator facility, the Beijing Radioactive Ion-beam Facility (BRIF) is being constructed in China Institute of Atomic Energy (CIAE). This project consists of an 100 MeV proton compact cyclotron, a two-stage ISOL system, a superconducting linac booster and various experimental terminals. The beam commissioning of the cyclotron was launched by the end of 2013 and on July 4, 2014 the first 100 MeV proton beam was received on a temporary target which was positioned at the outlet of the cyclotron. The beam current was stably maintained at above 25 μA for about 9 h on July 25, 2014 and the cyclotron is now ready for providing CW proton beam on target-source for RIB production. The beam current is expected to be increased to 200–500 μA in the coming years. The installation of the ISOL system is finished and the stable ion beam test shows it can reach a mass resolution better than 10,000. It is expected to generate dozens of RIB by 100 MeV proton beam. In addition, this paper also introduces the recent progress of the pre-study of an 800 MeV, 3–4 MW separate-sector proton cyclotron, which is aimed to provide high power proton beam for various applications, such as neutron and neutrino physics, proton radiography and nuclear data measurement and ADS system.

    This study is part of a series of analytical studies on nuclear legislation in OECD Member countries, prepared with the co-operation of the countries concerned. Each study has been organised on the basis of a standardised format for all countries, thus facilitating the comparison of information. The studies are intended to be updated periodically, taking into account modifications to the nuclear legislation in each country. This is the first update to the 1995 Edition. Unfortunately, due to the constraints of the OECD Publications Service, it covers only those legislative and institutional changes which, in our view, are of the greatest significance for our readers. Thus, you will find new chapters on Finland, Greece, Italy, Japan, Mexico, the Netherlands, Portugal and the United States. Changes to the nuclear legislation and institutions of the remaining countries will be incorporated into the next Update which is expected to be published at the end of 1997. (author)

    Kyoto University Research Reactor Institute (KURRI) and Sumitomo Heavy Industries, Ltd. (SHI) have developed a cyclotron-based neutron source for Boron Neutron Capture Therapy (BNCT). It was installed at KURRI in Osaka prefecture. The neutron source consists of a proton cyclotron named HM-30, a beam transport system and an irradiation and treatment system. In the cyclotron, H- ions are accelerated and extracted as 30 MeV proton beams of 1 mA. The proton beams is transported to the neutron production target made by a beryllium plate. Emitted neutrons are moderated by lead, iron, aluminum and calcium fluoride. The aperture diameter of neutron collimator is in the range from 100 mm to 250 mm. The peak neutron flux in the water phantom is 1.8 Multiplication-Sign 109 neutrons/cm{sup 2}/sec at 20 mm from the surface at 1 mA proton beam. The neutron source have been stably operated for 3 years with 30 kW proton beam. Various pre-clinical tests including animal tests have been done by using the cyclotron-based neutron source with {sup 10}B-p-Borono-phenylalanine. Clinical trials of malignant brain tumors will be started in this year.

    1999-01-01

    The design of targets for production of radioisotopes and radiopharmaceuticals of cyclotron to medical applications requires a detailed analysis of several variables such as: cyclotron operation conditions, choice of used materials as target and their physicochemical characteristics, activity calculation, the yielding of each radioisotope by irradiation, the competition of nuclear reactions in function of the projectiles energy and the collision processes amongst others. The objective of this work is to determine the equations for the calculation for yielding of solid targets at the end of the proton irradiation. (Author)

    In the last years, the technology for producing the important medical radionuclide technetium-99m by cyclotrons has become sufficiently mature to justify its introduction as an alternative source of the starting precursor [ 99m Tc][TcO 4 ] - ubiquitously employed for the production of 99m Tc-radiopharmaceuticals in hospitals. These technologies make use almost exclusively of the nuclear reaction 100 Mo(p,2n) 99m Tc that allows direct production of Tc-99m. In this study, it is conjectured that this alternative production route will not replace the current supply chain based on the distribution of 99 Mo/ 99m Tc generators, but could become a convenient emergency source of Tc-99m only for in-house hospitals equipped with a conventional, low-energy, medical cyclotron. On this ground, an outline of the essential steps that should be implemented for setting up a hospital radiopharmacy aimed at the occasional production of Tc-99m by a small cyclotron is discussed. These include (1) target production, (2) irradiation conditions, (3) separation/purification procedures, (4) terminal sterilization, (5) quality control, and (6) Mo-100 recovery. To address these issues, a comprehensive technology for cyclotron-production of Tc-99m, developed at the Legnaro National Laboratories of the Italian National Institute of Nuclear Physics (LNL-INFN), will be used as a reference example.

    In June of 1960 the US Atomic Energy Commission authorized the construction of a modern variable energy cyclotron facility at The University of Michigan to be used for research in nuclear spectroscopy. The Legislature of the State of Michigan made available funds for construction of a building to house the 83-inch cyclotron and auxiliary equipment as well as the University's remodeled 42-inch cyclotron. The research program centered around the 83-inch cyclotron was funded by the AEC and its successors, the Energy Research and Development Administration (ERDA) and the Department of Energy (DOE), from September 1964 through March 1977. The program represented a continuation of the research effort using the 42-inch cyclotron facility which had been supported continuously by the AEC since February 1950. This final report to DOE briefly describes the research facility, the research program, and highlights the principal accomplishments of the effort. It begins with a historical note to place this effort within the context of nuclear physics research in the Department of Physics of the University of Michigan

    2011-02-01

    Radioactive isotopes are used in a wide range of medical, biological, environmental and industrial applications. Cyclotrons are the primary tool for producing the shorter-lived, proton-rich radioisotopes currently used in a variety of medical applications. Although the primary use of the cyclotron-produced short-lived radioisotopes is in PET/CT (positron emission tomography/computed tomography) and SPECT (single photon emission computed tomography) diagnostic medical procedures, cyclotrons are also producing longer-lived isotopes for therapeutic procedures as well as for other industrial and applied science applications. Commercial suppliers of cyclotrons are responding by providing a range of cyclotrons in the energy range of 3-70MeV for the differing needs of the various applications. These cyclotrons generally have multiple beams servicing multiple targets. This review article presents some of the applications of the radioisotopes and provides a comparison of some of the capabilities of the various current cyclotrons. The use of nuclear medicine and the number of cyclotrons supplying the needed isotopes are increasing. It is expected that there will soon be a new generation of small "tabletop" cyclotrons providing patient doses on demand.

    More than 3000 nuclides are known, of which approximately 2700 are radioactive, and rest are stable. The majority of radionuclides are artificially produced in the reactor and cyclotron. In a cyclotron, Charge particle such as proton, Deuteron, á (Alpha) particle, 3 He particles and so forth are accelerated in circular paths within the Dees under vacuum by means of an electromagnetic field. These accelerated particles can possess few KeV to several BeV of kinetic energy depending on the design of the cyclotron. At our setup we have an 11 MeV dual beam multi target cyclotron which is capable producing 11 C, 13 N, 15 O, 18 F and 2 F radioisotopes and all have been successfully produced and tested in our lab. Earlier cyclotrons were the best source of high-energy beams for nuclear physics experiments; several cyclotrons are still in use for this type of research. Cyclotrons can be used to treat cancer. Ion beams from cyclotrons can be used, as in proton therapy. The positron emitting isotopes are suitable for PET imaging. As discussed we are producing mainly Carbon-11, Nitrogen-13, Oxygen-15, and Fluorine-18: These are positron emitters used in PET for studying brain physiology and pathology, in particular for localizing epileptic focus, and in dementia, psychiatry and neuropharmacology studies. So these are having significant role in diagnosis of Oncological, Neurological and Cardiological disorder. More than ninety percent we are producing 18 F in FDG. 18 F in FDG (Flouro-Deoxy-glucose) has become very important in detection of cancers and the monitoring of progress in their treatment, using PET. Medical cyclotron is complex equipment requiring delicate handling by highly trained personnel. The aim of this article is to highlight few finer aspects of Medical cyclotron operation, including precautions for safety and smooth functioning of this sophisticated equipment. (author)

    This article comments the creation of the World Institute for Nuclear Security (WINS) in September 2008 in Vienna. The creation of this institution is the result of a project initiated by the USA in 2004. The author recalls the process which leaded to this creation: workshops organised by the Nuclear Threat Initiative (NTI) and the Institute for Nuclear Materials Management (INMM), creation of a coordination committee, and expert meeting in Baden. He indicates how the WINS is financed (by the NTI, the US DoE, and Norway) and its future costs. He briefly describes its structure and operation, its mission, scope and activities (11 fields of activity have been defined). He recalls the various international instruments (conventions, resolutions, institutions, initiatives) related to nuclear security and to the struggle against nuclear threat and terrorism, and indicates how the WINS considers them (an insufficient and inefficient, but existing support). He finally indicates issues to be addressed to better define the WINS' role

    Cyclotron accelerators are prolific sources of charged particle for the production of radionuclides and have become an essential tool in the practice of modern nuclear medicine by providing reliably radiotracers for SPECT and PET studies. In a recent survey conducted by the IAEA in 2001 (1) , the growth in the number of cyclotron facilities installed in laboratories and hospitals in developed as well as developing nations was put into evidence This trend, which started in the late 70's, continues up to the present time, and all indications are that it will continue in the next future. The reasons for this growth are several, amongst them it can be mentioned the fact that the technology involved has became more user or 'hospital friendly', third party reimbursement for several of clinical studies based on F-18 PET radiopharmaceuticals at least in some of the advanced countries starting with F-18FDG in 1998, and above all, the clear, irrefutable and demonstrable Conclusion of the positive cost/benefit outcomes of PET studies in the field of oncology and to a lesser degree, thus far, for cardiology and neurology. It is however recognized that the overall financial cost of the technology, which comprises the premises to house the facility, the cyclotron accelerator, the corresponding radiochemistry and quality control equipment and the PET camera can nevertheless be an expensive proposition that requires careful advance planning. This fact is even more relevant when the facility is planed for installation in a developing country which frequently, in addition to having a lack of sufficient financial resources, do have shortages of qualify human resources for advance planning and later, to run efficiently the facility. Several are the steps that needs consideration when planning a cyclotron facility, the most critical ones are a careful definition of the mission and scope of the facility including the utilization programme of the facility as a whole, followed by a

    44 Sc is a promising positron emission tomography (PET) radionuclide (T 1/2  = 4.04 hours, E β+average  = 632 keV) and can be made available, using a cyclotron production route, in substantial quantities as a highly pure product. Herein, the authors report on a first-in-human PET/CT study using 44 Sc-DOTATOC prepared with cyclotron-produced 44 Sc. The production of 44 Sc was carried out through the 44 Ca(p,n) 44 Sc nuclear reaction at Paul Scherrer Institut, Switzerland. After separation, 44 Sc was shipped to Zentralklinik Bad Berka, Germany, where radiolabeling was performed, yielding radiochemically pure 44 Sc-DOTATOC. Two patients, currently followed up after peptide receptor radionuclide therapy of metastatic neuroendocrine neoplasms, participated in this proof-of-concept study. Blood sampling was performed before and after application of 44 Sc-DOTATOC. PET/CT acquisitions, performed at different time points after injection of 44 Sc-DOTATOC, allowed detection of even very small lesions on delayed scans. No clinical adverse effects were observed and the laboratory hematological, renal, and hepatic profiles remained unchanged. In this study, cyclotron-produced 44 Sc was used in the clinic for the first time. It is attractive for theranostic application with 177 Lu, 90 Y, or 47 Sc as therapeutic counterparts. 44 Sc-based radiopharmaceuticals will be of particular value for PET facilities without radiopharmacy, to which they can be shipped from a centralized production site.

    The central region of the VINCY Cyclotron, the main part of the TESLA Accelerator Installation, is designed to operate with two external ion sources: an ECR ion source for heavy ions, and a multicusp ion source for H - and D - ions. A tilted spiral inflector with an electric bending radius of 25 mm is used to bend the beams into the median plane of the Cyclotron at the magnetic radius of 16 mm. The optical properties of the inflector were studied, and an effort to minimize the inflector fringe field, using the RELAX3D code, for the calculation of the electric potential distribution, was made.

    1991-01-01

    The albedo neutron dosimeter is calibrated directly at the work place due to its high energy dependence. This thesis deals with the study, analysis and application of neutron measurement techniques in order to obtain information about the neutron spectrum and neutron dose equivalent at several representative working places of the cyclotron laboratory of the Nuclear Engineering Institute (IEN). These data are employed mainly in the calibration of the brazilian albedo neutron dosimeter. Bonner spheres and foil activation were used in neutron spectra measurements and the neutron dose equivalents were measured with the single sphere albedo technique. BF 3 and 3 He proportional detectors and 6 LiI scintillation detector were also used in these measurements. The single sphere technique turned out to be more appropriate for neutron dosimetry for calibrating the albedo dosimeter in the varying fields of the cyclotron. Calibration the albedo dosimeter in the varying fields of the cyclotron. Calibration factors were found for routine applications, when the workers are protected by shielding and for radiological accident applications, in the case that a worker is exposed inside the cyclotron room. In all situations the performance of the brazilian albedo dosimeter is compared with that of the german albedo dosimeters. (author)

    2018-05-01

    Full Text Available The U-120M cyclotron at the Nuclear Physics Institute (NPI of the Czech Academy of Sciences in Rez is used for radiation hardness tests of electronics for high-energy physics experiments. These tests are usually carried out with proton fluxes of the order of 105–109 proton·cm−2·s−1. Some tests done for the upgrade of the Inner Tracking System of the ALICE experiment at CERN, however, required proton beam intensities several orders of magnitude lower. This paper presents a method which has been developed to achieve the proton beam flux of the order of 1 proton · cm−2·s−1. The method is mainly based on reduction of the discharge current in the cyclotron internal Penning type ion source. Influence of this new operation mode on the lifetime of ion source cathodes is discussed.

    Nuclear Forensics capability has been developed under the international collaborations. For its effective function, technical development in analysis of seized nuclear materials as well as the institutional development in comprehensive response framework are required under individual national responsibility. In order to keep the “chain of custody” in the proper operation of sample collection at the event scene, radiological analysis at the laboratory, storage of the samples, and further inspection and trial, close cooperation and information sharing between relevant organisations are essential. IAEA issues the Implementing Guide to provide the model action plan and assists individual national development. Some countries at the advancing stage of national response framework, promote the international cooperation for the technical improvement and awareness cultivation. Examples in such national developments will be introduced and prospective technical/institutional prerequisite for nuclear forensics response framework will be studied. (author)

    A 14 MeV high intensity compact cyclotron, CYCIAE-14, was built at China Institute of Atomic Energy (CIAE). An injection system based on the external H- ion source was used on CYCIAE-14 so as to provide high intensity beam, while most positron emission tomography cyclotrons adopt internal ion source. A beam intensity of 100 μA/14 MeV was extracted from the cyclotron with a small multi-cusp H- ion source (CIAE-CH-I type) and a short injection line, which the H- ion source of 3 mA/25 keV H- beam with emittance of 0.3π mm mrad and the injection line of with only 1.2 m from the extraction of ion source to the medial plane of the cyclotron. To increase the extracted beam intensity of the cyclotron, a new ion source (CIAE-CH-II type) of 9.1 mA was used, with maximum of 500 μA was achieved from the cyclotron. The design and test results of the ion source and injection line optimized for high intensity acceleration will be given in this paper.

    Here we present results of the computer design of the structural elements of a compact cyclotron by the example of HITFiL cyclotron selected as the driving accelerator that is under construction at the Institute of Modern Physics (Lanzhou, China). In the article a complex approach to modeling of the compact cyclotron, including calculation of electromagnetic fields of the structural elements and beam dynamics calculations, is described. The existing design data on the axial injection, magnetic, acceleration and extraction systems of the cyclotron are used as a starting point in the simulation. Some of the upgrades of the cyclotron structural elements were proposed, which led to substantial improvement of the beam quality and transmission

  7. Feasibility Study for a Two-Energy Compact Medical Cyclotron Controlled by Two Pairs of Main Coils

    2013-01-01

    At Paul Scherrer Institute, Villigen, Switzerland, protons are accelerated for the proton therapy by a 250 MeV isochronous cyclotron. As for radiotherapy less energy is required (about 70 MeV) a carbon degrader reduces the extracted beam energy. This involves the increase of emittance, decrease of transmission, more activated components and a higher dose for the staff. By extracting a lower energy beam from the cyclotron, less degrade would be necessary and the above mentioned side-effects could be minimized. A possible solution could be to extract two energies from the cyclotron, 250 MeV for very deep located tumours and 230-235 MeV for others. A technically easy and affordable solution for this problem might be a two-energy cyclotron controlled by just two pairs of main coils. The feasibility of this solution has been analysed in this study. The compounded magnetic flux density B is the sum of the coil's and the iron's flux density. The amount caused by a coil is mainly responsible for the shape of the compounded flux density. Therefore a split of the coil pair was simulated to obtain more possibilities in the adjustment of a lower-energy beam to its ideal isochronous shape. The result is a simulated isochronous 240 MeV beam which was found with an tangential split of the coil pair, their repositioning and the increasing of current in the first coil pair and decreasing in the other one. The tangential split seemed to reduce the problem of the irons linear share of B. This feasibility study is seen as a first step before using 3D-capable software which considers a higher spatial resolution and the influence of temperature.(author)

    The increasing concentration of Pt, Pd and Rh in the environment is mainly due to the release of these elements from the catalytic converters of the motorvehicles. This situation makes it necessary to carry out metallotoxicological experiments on both cell cultures and laboratory animals, in order to assess their impact on living organisms after a Long Term and Low Level Exposure (LLE). Both nuclear reactions nat Ir(p,xn) and nat Os(α,xn) were investigated in the energy range up to 45 MeV for protons and 38 MeV for alpha-particles, in order to optimize the irradiation parameters for the production of 188,189,191 Pt. Several sets of thin- and thick-target excitation functions were determined experimentally by cyclotron irradiation at both Milano and Ispra cyclotrons. This paper reports the irradiation parameters studied and adopted and two radiochemical procedures for the separation of radio-Pt from an Os target, as well as from ruthenium, iridium and gold impurities. These procedures were used to obtain very high specific activity Pt radionuclides in No Carrier Added (NCA) form. Radionuclidic, radiochemical and chemical purity measurements were carried out by the use of several techniques like γ-spectrometry, ion-exchange radio-chromatography, atomic absorption spectrometry and neutron activation analysis.

    Several cyclotron development projects were recently realized by Ion Beam Applications S.A. (IBA). This contribution presents three of them: (i) the intensity enhancement of the Cyclone 30 cyclotron, a machine mainly used for the production of SPECT isotopes. This project is related with the increased demand for {sup 201}Tl because of the shortage of Mo/Tc generators from nuclear reactors, (ii) development of a new versatile multiple-particle K = 30 isotope-production cyclotron (the Cyclone 30XP) being able to accelerate H{sup -}, D{sup -} and also {alpha}-particles. The {alpha}-beam of this cyclotron will allow the production of new therapeutic isotopes (e.g. {sup 211}At) and (iii) commissioning of the Cyclone 70 cyclotron installed for Arronax in France. This machine is similar to the C30XP but provides higher energy (K = 70) and allows research on new types of medical isotopes.

    The CV-17 cyclotron, isochronous, compact, of variable energy is an accelerator of charged particles and is applied in several situations such as: radioisotopes production, neutron production, irradiation damage analysis, activation analysis. During the production of the particle beams, the parts components of the interior of the cyclotron are irradiated and become radioactive. Due the fact of the cyclotron require maintenance, the knowledgement of the radionuclides present is of primordial importance of the view point of the radioprotection. Taking the excitation function of a nuclear reaction is observed that determined reaction may happen and produce a radionuclide. The radionuclides formed in the parts components by charged particles are presented. (V.R.B.)

    This report covers the activities in 1978 at the Research Institute of Physics, Stockholm, Sweden. During this year the construction work on the caves for nuclear physics research in the new experimental hall has been completed. The cyclotron has been started up again after a shut-down of about 15 months. A new mini-computer system has been bought and installed at the institute which will be used for on-line data aquisition as well as for off-line computations and analysis. The experimental nuclear physics program has naturally been hampered by the shut-down of the cyclotron. During the main part of the year, experiments with participation of nuclear physicists from the institute have been carried out at laboratories in Uppsala, Aabo, Risoe, Darmstadt and Orsay. The collaboration with the CERN group studying exotic atoms has continued. The activities of the group working in the field of atomic physics at the 400kV accelerator show a clear trend towards the studies of reaction phenomena occuring in collisions of ions with solids and gases. The construction of the new high-power electron accelerator for research in time-resolved precision spectroscopy of atoms and molecules has been completed. The fusion-related experimental program of the surface physics group has continued with an emphasis on the work done in collaboration with the Institut fur Plasmaphysik, KFA, Julich. In order to be able to perform in situ sputtering and thin film migration studies, a new ultra-high-vacuum chamber is being connected simultaneously to the new 100V-10kV low-energy accelerator and the 2MV Van de Graaff accelerator.

    2009-01-01

    Two half-wave RF systems with vertical resonators tanks located in a yoke of a magnet will be used for acceleration of charged particles in range from H- to Xe +1 8 with energy 72 - 2 MeV/u. The range of frequency from 18.25 MHz up to 32 MHz is provided by changing of the length of resonators. The calculated quality-factor of RF system is equal from 5000 to 6000. At a voltage rating of 60 kV on two dees it is necessary to use the HF generator with an output power about 25 kW. The basic parameters of a HF system of a cyclotron DC - 72 are shown in the given article. The results are obtained on the basis of numerical calculations conducted with the software package POISSON SUPERFISH and MicroCap and they were checked by the series of measurements using the cyclotron built in Joint Institute for Nuclear Research. Measurements of the resonance system confirm the correctness of the new calculation methods and procedures for designing and optimizing various parts of HF circuits used in accelerators technology. By using of these methods it is possible to create a complete model of the entire accelerator HF system. The HF system consists of power generator, transmission lines, resonant system and monitoring and controlling system. (Author)

    This research discuss about basic design and systems of medical cyclotron that Malaysia currently have, its applications in radionuclide production and upcoming technologies of cyclotron. Surveys have been carried out on cyclotron facilities at Hospital Putrajaya and Wijaya International Medical Center, WIMC as well as reactor facility at Malaysia Nuclear Agency. The sources in this research also involves on-line and library searches. Information obtained are recorded, categorized, synthesized and discussed. systems of cyclotron of Hospital Putrajaya are further discussed in details. Based from the surveys carried out, it is found out that cyclotron facilities both in Hospital Putrajaya and WIMC only produce ( 18 F)FDG with radioactivity of 18 F produced in 2007 are 16479 mCi and 92546 mCi respectively. Survey also revealed that radioisotope production at Nuclear Malaysia has had its operation been ceased. A new radiopharmaceutical, namely CHOL is suggested to be synthesized by both facilities as a new PET tracer. Latest developments concerning technologies of cyclotron as well as other accelerators such as laser for future medical accelerator, prospect of boron neutron capture and the potential of hadron therapy in Malaysia are discussed here. Radioisotope production in Malaysia is expected to keep booming in future due to increase in usage of PET techniques and the construction of more compact, easy to handle and less costly cyclotrons.

  3. Cyclotrons in developing countries

    Cyclotron accelerators are prolific sources of charged particle for the production of radionuclides and have become an essential tool in the practice of modern nuclear medicine by providing reliable radiotracers for SPECT and PET studies. In a recent survey conducted by the IAEA in 2001, the growth in the number of cyclotron facilities installed in laboratories and hospitals in developed as well as developing countries was recorded. This trend, which started in the late 70's, continues in the present time also and all indications are that it will continue in the next five to ten years. The reasons for this growth are several: technology involved has become more user or 'hospital friendly', third party reimbursement for several clinical studies based on F-18 PET radiopharmaceuticals at least in some of the advanced countries started in 1998 and above all, the clear irrefutable and demonstrable conclusion of the positive cost/benefit outcomes of PET studies in the field of oncology to a lesser degree, thus far, for cardiology and neurology. It is however recognizable that the overall financial cost of the technology, which comprises the premises to house the facility, the cyclotron accelerator, the corresponding radiochemistry and quality control equipment and the PET cameras can be nevertheless an expensive proposition that requires careful advance planning. This fact is even more relevant when the facility is planned for installation in a developing country, which, frequently, in addition to having a lack of sufficient financial resources, do have shortage of qualified human resources to efficiently run the facility. In spite of the above, it is fact that more and more public as well as private organizations in the developing countries are setting up cyclotron/PET programmes or are seriously considering the installation of such a facility

    Development of a Cyclotron manufacturing facility begins with a business plan. Geographics, the size and activity of the medical community, the growth potential of the modality being served, and other business connections are all considered. This business used the customer base established by NuTech, Inc., an independent centralized nuclear pharmacy founded by Danny Allen. With two pharmacies in operation in Tyler and College Station and a customer base of 47 hospitals and clinics the existing delivery system and pharmacist staff is used for the cyclotron facility. We then added cyclotron products to contracts with these customers to guarantee a supply. We partnered with a company in the process of developing PET imaging centers. We then built an independent imaging center attached to the cyclotron facility to allow for the use of short-lived isotopes.

  7. Injection and extraction for cyclotrons

    Heikkinen, P.

    1994-01-01

    External ion sources for cyclotrons are needed for polarised and heavy ions. This calls for injection systems, either radial or axial. Radial injection is also needed when a cyclotron works as a booster after another cyclotron or a linear accelerator (usually tandem). Requirements for injection differ from separated sector cyclotrons where there is plenty of room to house inflectors and/or strippers, to superconducting cyclotrons where the space is limited by a small magnet gap, and high magnetic field puts other limitations to the inflectors. Several extraction schemes are used in cyclotrons. Stripping injection is used for H - and also for heavy ions where the q/m ratio is usually doubled. For other cases, electric and magnetic deflection has to be used. To increase the turn separation before the first deflector, both resonant and non-resonant schemes are used. In this lecture, external injection systems are surveyed and some rules to thumb for injection parameters are given. Extraction schemes are also reviewed. (orig.)

    The establishment of the National Medical Cyclotron (NMC) in the early 1990`s was the practical outcome of a vision, held by nuclear medicine professionals, to complement the available neutron-rich radionuclides produced in Australia, with neutron-deficient radionuclides. The NMC is operated by the Australian Nuclear Science and Technology Organisation (ANSTO) in collaboration with the Royal Prince Alfred Hospital (RPAH) in Sydney where the PET department is able to use the short-lived radiotracers to good advantage. Neutron-deficient radionuclides, are also produced by the NMC laboratories. The cyclotron-generated radionuclides are used in over 70,000 patient studies per year. 7 refs., 1 tab.

    1993-01-01

    The US nuclear electric utility industry established the Institute of Nuclear Power Operations (INPO) in 1979 to promote the highest levels of safety and reliability -- to promote excellence -- in the operation of its nuclear plants. After its formation, the Institute grew from a handful of on-loan personnel in late 1979 to an established work force of more than 400 permanent and on-loan personnel. INPO's early years were marked by growth and evolution of its programs and organization. The Institute now focuses primarily on the effectiveness and enhancement of established programs and activities. For INPO to carry out its role, it must have the support of its members and participants and a cooperative but independent relationship with the NRC. A basis for that support and cooperation is an understanding of INPO's role. This Institutional Plan is intended to provide that understanding by defining the Institute's role and its major programs. This plan considers the existing and projected needs of the industry and the overall environment in which INPO and its members and participants operate

  11. Oblique electron cyclotron emission for electron distribution studies (invited)

    International Nuclear Information System (INIS)

    Preische, S.; Efthimion, P.C.; Kaye, S.M.

    1997-01-01

    Electron cyclotron emission (ECE) at an oblique angle to the magnetic field provides a means of probing the electron distribution function both in energy and physical space through changes in and constraints on the relativistic electron cyclotron resonance condition. Diagnostics based on this Doppler shifted resonance are able to study a variety of electron distributions through changes in the location of the resonance in physical or energy space accomplished by changes in the viewing angle and frequency, and the magnetic field. For the case of observation across a changing magnetic field, such as across the tokamak midplane, the constraint on the resonance condition for real solutions to the dispersion relation can constrain the physical location of optically thin emission. A new Oblique ECE diagnostic was installed and operated on the PBX-M tokamak for the study of energetic electrons during lower hybrid current drive. It has a view 33 degree with respect to perpendicular in the tokamak midplane, receives second harmonic X-mode emission, and is constrained to receive single pass emission by SiC viewing dumps on the tokamak walls. Spatial localization of optically thin emission from superthermal electrons (50 endash 100 keV) was obtained by observation of emission upshifted from a thermal cyclotron harmonic. The localized measurements of the electron energy distribution and the superthermal density profile made by this diagnostic demonstrate its potential to study the spatial transport of energetic electrons on fast magnetohydrodynamic time scales or anomalous diffusion time scales. Oblique ECE can also be used to study electron distributions that may have a slight deviation from a Maxwellian by localizing the emission in energy space. (Abstract Truncated)

    Dielectric-loaded cylindrical waveguide configurations with an injected electron beam in which the growth rate of the cyclotron-Cherenkov instability surpasses that of the Cherenkov instability were sought by numerical treatment, and one configuration of this kind was found. This configuration consists of a metallic core and an outer metallic cylinder with a dielectric liner on the inner surface. Based on the calculations, an experimental device was designed and assembled to investigate experimentally radiation due to the cyclotron-Cherenkov instability. Beam propagation in the dielectric-loaded coaxial waveguide and microwave radiation due to the cyclotron-Cherenkov instability and the Cherenkov instability were studied. (author). 6 figs., 10 refs.

    Cyclotrons continue to be efficient accelerators for radioisotope production. In recent years, developments in the accelerator technology have greatly increased the practical beam current in these machines while also improving the overall system reliability. These developments combined with the development of new isotopes for medicine and industry, and a retiring of older machines indicates a strong future for commercial cyclotrons. In this paper we will survey recent developments in the areas of cyclotron technology, and isotope production, as they relate to the new generation of commercial cyclotrons. We will also discuss the possibility of systems capable of extracted energies up to 100 MeV and extracted beam currents of up to 2.0 mA. (author). 6 refs., 2 tabs., 3 figs

    As a driven accelerator, the CYCIAE-100 cyclotron is designed by China Institute of Atomic Energy for the Beijing Radio Ion-beam Facility project. The cyclotron RF system is designed to use two RF power sources of 100 kW to drive two half-wavelength cavities respectively. Two Dee accelerating electrodes are kept separately from each other inside the cyclotron, while their accelerating voltages are maintained in phase by the efforts of LLRF control. An analog–digital hybrid LLRF system has been developed to achieve cavity tuning control, dee voltage amplitude and phase stabilization etc. The analog subsystems designs are focused on RF signal up/down conversion, tuning control, and dee voltage regulation. The digital system provides an RF signal source, aligns the cavity phases and maintains a Finite State Machine. The digital parts combine with the analog functions to provide the LLRF control. A brief system hardware introduction will be given in this paper, followed by the review of several major characteristics of the digital control in the 100 MeV cyclotron LLRF system. The commissioning is also introduced, and most of the optimization during the process was done by changing the digital parts.

    Biomedical Cyclotrons have a very long life, but there eventually comes a time when any piece of equipment has to be retired from service. From time to time, we have the opportunity to help find new homes for used cyclotrons which, with relatively modest overhaul and refurbishment, can have many additional years of productive service, and thus represent a very valuable asset. The reasons for retiring a cyclotron vary, of course, but in our experience it is often due to an institution's changing priorities or changing needs, rather than the due to any fundamental age-related deficiency in the cyclotron itself. In this paper we will report on the relocation and successful restoration of a used TCC CP-42 cyclotron, which was moved from M.D. Anderson Hospital in Houston to Denton, Texas in early 1998, where it is presently being used for R and D and commercial production of biomedical isotopes. Ownership of the machine has been transferred to the University of North Texas; facility, manpower, and operational resources are provided by International Isotopes, Inc

    The Center for the Development of Radioisotopes and Radiopharmaceuticals - National Nuclear Energy Agency (P2RR-BATAN) has one Cyclotron type CS-30 with maximum 30 MeV proton energy. It is used since 1990 for 201 Tl production. The main use of 201 Tl in Indonesia is for diagnosis and assessment of myocardial ischaemia, especially diagnosis of coronary artery disease, viability of the heart muscle and forecasting the outcome for patients with coronary disease. The Cyclotron facility is supported with a solid target station, two hot cells and the chemical equipment for electroplating. The yield of 201 Tl production currently achieved around 40-50%. The irradiation technique and chemical separation should be improved. We are also very interested in the development of the production of 103 Pd via 103 Rh (p,n) 103 Pd reaction. The objective of this proposal will support the main program of the National Nuclear Energy Agency (BATAN) in enhancement of health care and in providing Cyclotron produced radiopharmaceuticals for hospitals

    Compant La Fontaine, A.; Pashkovsky, V.G.

    1995-01-01

    The plasma separation process by ion cyclotron resonance heating (ICRH) is studied both theoretically and experimentally on two devices: the first one called ERIC (Ion Cyclotron Resonance Experiment) at Saclay (France) [P. Louvet, Proceedings of the 2nd Workshop on Separation Phenomena in Liquids and Gases, Versailles, France, 1989, edited by P. Louvet, P. Noe, and Soubbaramayer (Centre d'Etudes Nucleaires de Saclay and Cite Scientifique Parcs et Technopoles, Ile de France Sud, France, 1989), Vol. 1, p. 5] and the other one named SIRENA at the Kurchatov Institute, Moscow, Russia [A. I. Karchevskii et al., Plasma Phys. Rep. 19, 214 (1993)]. The radio frequency (RF) transversal magnetic field is measured by a magnetic probe both in plasma and vacuum and its Fourier spectrum versus the axial wave number k z is obtained. These results are in agreement with the electromagnetic (EM) field calculation model based on resolution of Maxwell equations by a time-harmonic scheme studied here. Various axial boundary conditions models used to compute the EM field are considered. The RF magnetic field is weakly influenced by the plasma while the electric field components are strongly disturbed due to space-charge effects. In the plasma the transversal electric field is enhanced and the k z spectrum is narrower than in vacuum. The calculation of the resonant isotope heating is made by the Runge--Kutta method. The influence of ion--ion collisions, inhomogeneity of the static magnetic field B 0 , and the RF transversal magnetic field component on the ion acceleration is examined. These results are successfully compared with experiments of a minor isotope 44 Ca heating measurements, made with an energy analyzer. copyright 1995 American Institute of Physics

    An electrostatic deflector is used for extraction of accelerated particles at the isochronous cyclotron U-150 (Institute of Nuclear Physics, Kazakhstan). Efficiency of beam extraction depends on a set of factors. Decisive is heat state of the septum and essentially beam extraction is limited by beam power dissipation on the deflector. Due to the works carried on for radioisotope production, determination of septum's maximal heat loading, optimization of the septum's geometry represent the interest. Maximum heat loading of deflector's septum and it's dependence on septum's geometry and thermal-physical properties of septum's material are presented in the paper as result of numerical calculation. The obtained results are discussed

    Positron Emission Tomography (PET) is a highly sensitive and accurate nuclear medicine imaging technology but the major problem of this technique is the use of radioisotopes with short half-life, less than two hours. The production and selling of short half-life radioisotopes used to be monopoly of the Brazilian Government. In 2006, a Constitutional Amendment revoked the state monopoly due to the need for the use of short half-life radioisotopes in nuclear medicine centers very far from the government production facilities. The aim of this study is to describe the current status of short half-life radioisotopes production in Brazil and discuss some licensing process. In Brazil, as has been occurring worldwide, the number of nuclear medicine centers is increasing. Currently there are 123 services performing PET scans in Brazil. There are 14 cyclotrons operating in Brazil. The type of licensing process conducted in Brazil does not take into account the population density of each state, with a free competition model being adopted. Because of this there is a lot of equipment concentrated in the Southeast and no cyclotrons operating in the Northern part of the country. One of the biggest obstacles during the licensing process is the designation of qualified personnel as operation workers and radiation safety officers. The number of cyclotron accelerators and PET/CT equipment increased in recent years. However, a number of external factors such as the distance from the nuclear medicine centers, and qualified personnel have proved crucial for the economic viability of this type of facility.

    The LNS Superconducting Cyclotron, named “Ciclotrone Superconduttore” (CS), has been in operation for more than 20 years. A wide range of ion species from hydrogen to lead, with energy in the range 10 to 80 AMeV, have been delivered to users. The maximum beam power is limited to 100 W due to the beam dissipation on the electrostatic deflectors. To fulfil the demand of users aiming at studying rare processes in nuclear physics, an upgrade of the cyclotron is necessarily intended to increase the intensity of ion beams with mass lower than 40 a.m.u. up to a power 10 kW. This will be achieved by means of extraction by stripping. This solution needs to replace the cryostat including the superconducting coils. The present capability of the cyclotron will be maintained, i.e. all the ion species allowed by the operating diagram will be available, being extracted by electrostatic extraction. In addition to the high power beams for nuclear physics, it will be possible to produce medical radioisotopes like 211At using an internal target.

    As important components integrated in transmission lines of electron cyclotron heating systems, polarizers are mainly used to obtain the desired polarization for highly efficient coupling between electron cyclotron waves and plasma. The polarization strategy for 105-GHz electron cyclotron heating systems of HL-2M tokamak is studied in this paper. Considering the polarizers need high efficiency, stability, and low loss to realize any polarization states, two sinusoidal-grooved polarizers, which include a linear polarizer and an elliptical polarizer, are designed with the coordinate transformation method. The parameters, the period p and the depth d, of two sinusoidal-grooved polarizers are optimized by a phase difference analysis method to achieve an almost arbitrary polarization. Finally, the optimized polarizers are manufactured and their polarization characteristics are tested with a low-power test platform. The experimental results agree well with the numerical calculations, indicating that the designed polarizers can meet the polarization requirements of the electron cyclotron heating systems of HL-2M tokamak.

    A 12.5 MeV, 25 μA, proton compact superconducting cyclotron for medical isotope production has been designed and is currently in fabrication. The machine is initially aimed at producing 13N ammonia for Positron Emission Tomography (PET) cardiology applications. With an ultra-compact size and cost-effective price point, this system will offer clinicians unprecedented access to the preferred radiopharmaceutical isotope for cardiac PET imaging. A systems approach that carefully balanced the subsystem requirements coupled to precise beam dynamics calculations was followed. The system is designed to irradiate a liquid target internal to the cyclotron and to minimize the need for radiation shielding. The main parameters of the cyclotron, its design, and principal steps of the development work are presented here.

    Particle accelerators were initially developed to address specific scientific research goals, yet they were used for practical applications, particularly medical applications, within a few years of their invention. The cyclotron's potential for producing beams for cancer therapy and medical radioisotope production was realized with the early Lawrence cyclotrons and has continued with their more technically advanced successors — synchrocyclotrons, sector-focused cyclotrons and superconducting cyclotrons. While a variety of other accelerator technologies were developed to achieve today's high energy particles, this article will chronicle the development of one type of accelerator — the cyclotron, and its medical applications. These medical and industrial applications eventually led to the commercial manufacture of both small and large cyclotrons and facilities specifically designed for applications other than scientific research.

    Advantages of fast neutrons in therapeutical application are now widely recognized. Fast neutrons are generated by bombarding a thick beryllium target with high energy protons and deuterons. The AVF cyclotrons which deliver 50 MeV protons and 25 MeV deuterons are commonly used and are commercially available now. At the treatment usually rotational irradiation is taken to prevent an injury to normal tissue from the high LET effect of fast neutrons. The construction cost of both cyclotrons and isocentric irradiation installation are relatively high, so that the spread of neutron therapy is obstructed. A superconducting cyclotron for neutron therapy application was proposed by a Chalk River group. This low cost design allows the installation to be a dedicated facility located in a hospital, and small size allows installations of the complete cyclotron in a rotatable gantry. The design studies of the superconducting cyclotron based on this idea are going on at Kyoto University. The full scale model experiments for a rf structure of the cyclotron were carried out.

    The first nuclear reactor was operated in 1957 at Tokai-mura in Japan. Since then radiation dose of workers has been controlled by nuclear institutions according to the Law for the Regulations of Nuclear Source Material, Nuclear Fuel Material and Reactors. However, many nuclear power plants and other nuclear facilities were built, resulting in the remarkable increase of workers in controlled areas. Further, periodical inspection and repair work at nuclear facilities were carried out by employees of subcontractors, who were engaged in such work at many different facilities, so that it was getting more and more difficult to obtain accurate information of radiation dose on these workers. In order to meet this situation, the open-quotes Radiation Dose Registration Center for Workersclose quotes (RADREC) was established in November 1977 within the open-quotes Radiation Effects Associationclose quotes (REA), which was founded in September 1960 for the purpose of supporting the research on radiation effects and radiation protection. In January 1978, RADREC was designated by the Government as an organization to preserve the records on exposure of radiation workers, which was linked up with the registration system

    An 11 MeV H - compact cyclotron used for medical radioactive isotope production is under construction in Institute of Fluid Physics, CAEP. The cyclotron magnet adopts the design of small valley gaps and coulee structure which can provide high average magnetic field and strong focus ability. To achieve 5 × 10 -4 measuring accuracy, a magnetic field mapping system has been developed. After iterative correction using field measurement data, the total phase excursion of the cyclotron is within ± 9° and the first harmonic is less than 10 -3 T, which are all acceptable. Furthermore, the beam testing declares the successful construction of the cyclotron magnet. Besides, some magnetic field influence factors were discussed, including the magnetic field distortion and measurement error. (authors)

    From the stripping points, the high intensity proton beam of a compact cyclotron travels through the fringe field area of the machine to the combination magnet. Starting from there the beams with various energy is transferred to the switching magnet for distribution to the beam line targets. In the design of the extraction and transport system for the compact proton cyclotron facilities, such as the 70 MeV in France and the 100 MeV in China, the space charge effect as the beam crosses the fringe field has not been previously considered; neither has the impact on transverse beam envelope coupled from the longitudinal direction. Those have been concerned much more with the higher beam-power because of the beam loss problem. In this paper, based on the mapping data of 70 MeV cyclotron including the fringe field by BEST Cyclotron Inc (BEST) and combination magnet field by China Institute of Atomic Energy (CIAE), the beam extraction and transport are investigated for the 70 MeV cyclotron used on the SPES project at Istituto Nazionale di Fisica Nucleare, Laboratori Nazionali di Legnaro (INFN-LNL). The study includes the space charge effect and longitudinal and transverse coupling mentioned above, as well as the matching of beam optics using the beam line for medical isotope production as an example. In addition, the designs of the ±45° switching magnets and the 60° bending magnet for the extracted beam with the energy from 35 MeV to 70 MeV have been made. Parts of the construction and field measurements of those magnets have been done as well. The current result shows that, the design considers the complexity of the compact cyclotron extraction area and fits the requirements of the extraction and transport for high intensity proton beam, especially at mA intensity levels.

    From the stripping points, the high intensity proton beam of a compact cyclotron travels through the fringe field area of the machine to the combination magnet. Starting from there the beams with various energy is transferred to the switching magnet for distribution to the beam line targets. In the design of the extraction and transport system for the compact proton cyclotron facilities, such as the 70 MeV in France and the 100 MeV in China, the space charge effect as the beam crosses the fringe field has not been previously considered; neither has the impact on transverse beam envelope coupled from the longitudinal direction.

    Introduction Technetium-99m, supplied in the form of 99Mo/99mTc generators, is the most widely used radioisotope for nuclear medical imaging. The parent isotope 99Mo is currently produced in nuclear reactors. Recent disruptions in the 99Mo supply chain [1] prompted the development of methods for the direct accelerator-based production of 99mTc. Our approach involves the 100Mo(p,2n)99mTc reaction on isotopically enriched molybdenum using small medical cyclotrons (Ep ≤ 20 MeV), which is ...

  19. Waste management in the Institute for Nuclear Sciences 'Vinca' - Belgrade

    2004-01-01

    The Vinca Institute of Nuclear Sciences served for many years as the only Yugoslav (Serbia and Montenegro) nuclear institute. Therefore, it acted for many years as national storage facility for the radioactive waste from all institutional (medical, military, etc.) activities. The interim storage was situated within the Vinca Institute historically at several different places. The main fraction of the wastes is stored in two metallic hangars. In addition, underground stainless steel tanks in concrete shields have been constructed to accept all processed liquid waste from the research reactor RA. The current situation of the interim storage facilities is not satisfactory. However, the principle limitation for improvements of the waste management at the Vinca Institute lies in the fact that long-term solutions cannot be addressed at the moment. Plans for a final repository for radioactive waste do not exist yet in the Serbia and Montenegro. Consequently, waste management can only address an interim solution. In order to conduct all waste management activities in a safe manner, an overall strategy and study for improvement/rearrangement of radioactive waste storage facilities was developed which addresses all wastes and their management. The IAEA is providing assistance to these activities. This support includes a project which has been initiated by the IAEA to improve the waste management at the Vinca Institute. This paper describes the current status of the development of this overall strategy and study for improvement/rearrangement of radioactive waste storage facilities. The information available and the current status of the development of concepts for the processing and storage of the waste are summarised. (author)

    1986-01-01

    The University of Michigan (U of M) Cyclotron/Positron Emission Tomography (PET) facility consists of a cyclotron (Model CS-30, The Cyclotron Corporation), radiochemistry laboratory, and Pet scanner. Accelerator-produced radioactive materials, such as, carbon-11 and oxygen-15 are typically emitted from the Cyclotron/PET facility through short stacks located on the roof. This project studied the dispersion of emissions from the facility within the medical complex. To achieve this purpose, the research project had three phases: a physical modeling study; a preliminary field smoke release study; and, a field study using a tracer gas to simulate emission dispersion from the U of M Cyclotron/PET facility vault stack. The objective was to determine normalized concentrations, under selected wind directions and speeds, for use in establishing radionuclide concentrations at the air intakes of the Cyclotron/PET facility and surrounding buildings and at selected ground-level locations

    1987-01-01

    In the medium size nuclear fusion experiment facility JFT-2M in the Japan Atomic Energy Research Institute, the research on the high efficiency plasma confinement mode has been advanced, and in the experiment in June, 1987, the formation of a high efficiency confinement mode was successfully controlled by electron cyclotron heating, for the first time in the world. This result further advanced the control of the formation of a high efficiency plasma confinement mode and the elucidation of the physical mechanism of that mode, and promoted the research and development of the plasma heating by electron cyclotron heating. In this paper, the recent results of the research on a high efficiency confinement mode at the JFT-2M are reported, and the role of the JFT-2M and the experiment on the improvement of core plasma performance are outlined. Now the plasma temperature exceeding 100 million deg C has been attained in large tokamaks, and in medium size facilities, the various measures for improving confinement performance are to be brought forth and their scientific basis is elucidated to assist large facilities. The JFT-2M started the operation in April, 1983, and has accumulated the results smoothly since then. (Kako, I.)

    The production methods for seven radioisotopes, Ga-67, Sr-85, Pd-103, In-111, Tm-167, Hg-197 and Pb-203, by using a classical 1.5m cyclotron in the Institute of Physics and Power Engineering, Obninsk, USSR, are described. At present, more than 50 cyclotrons in different countries are used for the production of radioisotopes applied to medicine. Radioisotopes are produced with the cyclotron in the I.Ph.P.E. in the form of irradiated targets, which are delivered to Moscow radiopharmaceutical factory, where radiopharmaceuticals are produced on the base of these targets. The cyclotron is operated in two regimes providing the acceleration of protons, deuterons and alpha -particles. Two types of target assemblies are used for irradiation, the one is intended for the internal beam, and the other is for the external beam. The reactions used for the production of seven radioisotopes described above, the types of targets, particle energy, respective irradiated materials, beam current, thick target yield and the amount of respective radioisotopes produced per year are reported. Metals have large heat conductivity, therefore the use of metal targets increases beam current, and increases the production rate of radioisotopes.

    This report describes our continuing long term goal of promoting nuclear medicine applications by improving the scientific basis for tumor diagnosis, treatment and treatment follow-up based on the use of cyclotron produced radiotracers in oncology. The program includes 3 interactive components: Radiochemistry/Cyclotron; Pharmacology; and Immunology. An essential strategy is as follows: novel radionuclides and radiotracers developed in the Radiochemistry/Cyclotron section will be employed in the Pharmacology and Immunology sections during the next year. The development of novel radionuclides and tracers is of course useful in and of itself, but their utility is greatly enhanced by the interaction with the immunology and pharmacology components of the program.

    The ASI 'Topics in Atomic and Nuclear Collisions' was organized in Predeal from August 31 to September 11. It brought together people with a broad interest in Atomic and Nuclear Physics from several research institutes and universities in Ro­ mania and 16 other countries. The school continues a tradition that started on a small scale back in 1968, fo­ cussing mainly on current problems in nuclear physics. Though the organizing of this edition started very late and in very uncertain economic and financial conditions, it turned out to be the largest meeting of this type ever organized in Romania, both in topics and participation. There were many applicants for participation and grants, considerably more than could be handled. The selection made by the local organizing committee was based on the following criteria: a proper balance of atomic and nuclear physicists, a broad representation of people from Research Institutes and Universities, a balanced par­ ticipat!on with respect to age, sex, nationali...

    Energy Technology Data Exchange (ETDEWEB)

    1993-07-01

    The period 1 April 1992--31 March 1993 saw the initial runs of three new spectrometers, which constitute a major portion of the new detection capabilities developed for this facility. These devices are the Proton Spectrometer (PSP) (data from which are shown on the cover of this document), the Mass Achroniat Recoil Mass Spectrometer (MARS), and the Multipole Dipole Multipole (MDM) Particle Spectrometer. The ECR-K500 cyclotron combination operated 5,849 hours. The beam was on target 39% of this time. Studies of nuclear dynamics and nuclear thermodynamics using the neutron ball have come to fruition. A critical re-evaluation of the available data on the giant monopole resonance indicated that the incompressibility is not specified to a range smaller than 200--350 MeV by those data. New systematic experiments using the MDM spectrometer are now underway. The MEGA collaboration obtained the first data on the {mu} {yields} e{gamma} decay rate and determination of the Michel parameter in normal {mu} decay. Experiments appear to confirm the existence of monoenergetic pair peaks even for relatively low Z{sub projectile} -- Z{sub target} combinations. Studies of the ({alpha},2{alpha}) knockout reaction indicate that this reaction may prove to be a valuable tool for determination of reaction rates of astrophysical interest. Theoretical work reported in this document ranges from nuclear structure calculations using the IBM-2 model to calculations of kaon production and the in-medium properties of the rho and phi mesons. Nuclear dynamics and exotic shapes and fragmentation modes of hot nuclei are also addressed. New measurements of x-ray emission from highly ionized ions, of molecular dissociation and of surface interactions are reported. The research is presented in nearly 50 brief summaries usually including data and references.

    Development of a 13 MeV cyclotron for Positron Emission Tomography (PET) has been in progress since April 1999 at the Korea Cancer Center Hospital (KCCH). The study has been carried out in a joint collaboration between KCCH and the Pohang University of Science and Technology (POSTECH). Increasing desire for an uninterrupted, reliable and timely supply of the isotopes to customers has prompted obtaining a dedicated 5-13 MeV cyclotron for PET applications and pursuing the purchase of another 30MeV medical cyclotron in the very near future. A decision has been made to design the PET cyclotron in Korea. This will not only ease the problems associated with maintenance during operation but also keep the door open for continuous upgrading of the machine in the future

    A recently described nuclear grading system predicted survival in patients with epithelioid malignant pleural mesothelioma. The current study was undertaken to validate the grading system and to identify additional prognostic factors. We analyzed cases of epithelioid malignant pleural mesothelioma from 17 institutions across the globe from 1998 to 2014. Nuclear grade was computed combining nuclear atypia and mitotic count into a grade of I-III using the published system. Nuclear grade was assessed by one pathologist for three institutions, the remaining were scored independently. The presence or absence of necrosis and predominant growth pattern were also evaluated. Two additional scoring systems were evaluated, one combining nuclear grade and necrosis and the other mitotic count and necrosis. Median overall survival was the primary endpoint. A total of 776 cases were identified including 301 (39%) nuclear grade I tumors, 354 (45%) grade II tumors and 121 (16%) grade III tumors. The overall survival was 16 months, and correlated independently with age (P=0.006), sex (0.015), necrosis (0.030), mitotic count (0.001), nuclear atypia (0.009), nuclear grade (<0.0001), and mitosis and necrosis score (<0.0001). The addition of necrosis to nuclear grade further stratified overall survival, allowing classification of epithelioid malignant pleural mesothelioma into four distinct prognostic groups: nuclear grade I tumors without necrosis (29 months), nuclear grade I tumors with necrosis and grade II tumors without necrosis (16 months), nuclear grade II tumors with necrosis (10 months) and nuclear grade III tumors (8 months). The mitosis-necrosis score stratified patients by survival, but not as well as the combination of necrosis and nuclear grade. This study confirms that nuclear grade predicts survival in epithelioid malignant pleural mesothelioma, identifies necrosis as factor that further stratifies overall survival, and validates the grading system across multiple

  4. Methodology for nuclear magnetic resonance and ion cyclotron resonance mass spectrometry

    2014-01-01

    This thesis encompasses methodological developments in both nuclear magnetic resonance and Fourier transform ion cyclotron resonance mass spectrometry. The NMR section explores the effects of scalar relaxation on a coupled nucleus to measure fast exchange rates. In order to quantify these rates accurately, a precise knowledge of the chemical shifts of the labile protons and of the scalar couplings is normally required. We applied the method to histidine where no such information was available a priori, neither about the proton chemical shifts nor about the one-bond scalar coupling constants J( 1 H 15 N), since the protons were invisible due to fast exchange. We have measured the exchange rates of the protons of the imidazole ring and of amino protons in histidine by indirect detection via 15 N. Not only the exchange rate constants, but also the elusive chemical shifts of the protons and the coupling constants could be determined. For the mass spectrometry section, the ion isolation project was initiated to study the effect of phase change of radiofrequency pulses. Excitation of ions in the ICR cell is a linear process, so that the pulse voltage required for ejecting ions must be inversely proportional to the pulse duration. A continuous sweep pulse propels the ion to a higher radius, whereas a phase reversal causes the ion to come to the centre. This represents the principle of 'notch ejection', wherein the ion for which the phase is reversed is retained in the ICR cell, while the remaining ions are ejected. The manuscript also contains a theoretical chapter, wherein the ion trajectories are plotted by solving the Lorentzian equation for the three-pulse scheme used for two-dimensional ICR. Through our simulations we mapped the ion trajectories for different pulse durations and for different phase relations. (author)

    Radiopharmaceuticals quickly furnish the information doctors need to establish a precise diagnosis of the patient's condition, and therefore to prescribe the most effective therapy. In cancerology, F18-FDG, the most widely used PET imaging tracer, excels in the early detection of cancer tumors, even very tiny ones, which it locates and clearly distinguishes from healthy surrounding tissues. IPEN-CNEN/SP has two cyclotron accelerators used mainly for radioisotope production to be utilized in nuclear medicine for diagnosis and therapy. The first is a CV-28 cyclotron, variable energy that came into operation in 1982, which was used to produce F18-FDG and Iodine 123 up to 1998. The second, a Cyclone 30 cyclotron, 30 MeV, commenced operation in 1998 for certification purpose, and due to increase demand for radiopharmaceuticals in Brazil, started F18-FDG production in 1999. Cyclotron Laboratory will be a reference Research and Developing Center in our country and will help the Brazilian and Latin-American community. It is necessary to have an adequate database to allow regular follow up and analysis of the individual dose distributions for each group involved in the cyclotron activities. These databases are also important means to assess the effectiveness of efforts in order to maintain doses ALARA and reduce inequalities. The official individual occupational dosimetry is provided by certified Laboratory of Thermoluminescent Dosimetry at IPEN-CNEN/SP. This paper describes the occupational doses distribution in Laboratory of Cyclotrons at IPEN-CNEN/SP from January, 1998 to July, 2000 and propose improvements for the future. (author)

    An ion cyclotron spectrometer may include a vacuum chamber that extends at least along a z-axis and means for producing a magnetic field within the vacuum chamber so that a magnetic field vector is generally parallel to the z-axis. The ion cyclotron spectrometer may also include means for producing a trapping electric field within the vacuum chamber that includes at least a first section that induces a first magnetron effect that increases a cyclotron frequency of an ion and at least a second section that induces a second magnetron effect that decreases the cyclotron frequency of an ion. The cyclotron frequency changes induced by the first and second magnetron effects substantially cancel one another so that an ion traversing the at least first and second sections will experience no net change in cyclotron frequency.

  11. Nuclear legislation: analytical study. Regulatory and institutional framework for nuclear activities

    International Nuclear Information System (INIS)

    2001-01-01

    Australia' s basic legislation in the nuclear field consists in five Acts passed by the Federal Parliament. These Acts are as follow: the South Pacific nuclear free zone treaty Act; the nuclear non-proliferation act; the Australian nuclear science and technology organisation act; the Australian nuclear science and technology organisation amendment act; the radiation protection and nuclear safety act. The two first Acts were prompted by the need for domestic legislation to implement Australia 's international obligations. The third arose from a long-standing recognition that the Atomic energy Act was inappropriate as the legislative basis for the activities of Australia 's national nuclear organisation. For its part the fourth Act introduced some necessary changes into the Australian nuclear science and technology organisation Act. Finally, the fifth act establishes a regime to regulate the operation of nuclear installations and the management of radiation sources, where the activities are undertaken by Commonwealth entities. Each of these Acts is discussed in more details in this work. (N.C.)

    This paper gives a status report on RIKEN Ring Cyclotron (RRC), successfully commissioned on December 16, 1986. The routine operation of RRC began in April, 1987, and was made until March 1988. April and May were devoted to the machine studies, and beams were delivered to the experiments from the end of May. Seven kinds of ion species from carbon to copper were used for the nuclear physics and atomic physics experiments during these one-year runs. High quality beams with transverse emittances less than 10 mm mrad, energy spread of approximately 0.1% and pulse width less than 300 psec were extracted. Since the middle of March, 1988, RRC has been shut down for extending the beam transfer lines and installing the various experimental setups. Next experimental program will start in July, 1988. The initial operational status of RRC is described as well as the running construction program of the new injector, a K70 AVF cyclotron with an external ECR ion source

    1984-01-01

    The experimental activities of the nuclear physics group at the University of Oslo have in 1983 as in the previous years mainly been centered around the SCANDITRONIX MC-35 cyclotron. The cyclotron has been in extensive use during the year for low-energy nuclear physics experiments. In addition it has been used for production of radionuclides for nuclear medicine, for experiments in nuclear chemistry and for corrosion and wear studies. After four years of operation, the cyclotron is still the newest nuclear accelerator in Scandinavia. The available beam energies (protons and alpha-particles up to 35 MeV and *sp3*He-particles up to 48 MeV, makes it a good tool for studies of highly excited low-spin states. The well developed on-line computer system has added to its usefulness. Most of the nuclear experiments during the year have been connected with the study of nuclear structure at high temperature. Experimens with the *sp3*He beam have given very interesting results. Theoretical studies have continued in the same field, and there has been a fruitful cooperation between experimental and theoretical physicists. Most of the experiments are performd as joint projects where physicists from two or three Nordic universities take part. (RF)

    The University of Iowa’s 20-year-old 17 MeV Scanditronix cyclotron underwent decommissioning in the summer of 2011. To satisfy local, state and federal regulations defining removal, transportation and long-term safe and environmentally secure disposal of the 22 ton activated cyclotron, a series of nuclear spectroscopic measurements were performed to characterize the nature and extent of proton and neutron activation of the 22-ton cyclotron, its associated targets, and the concrete wall that was demolished to remove the old cyclotron. Neutron activation of the concrete wall was minimal and below exempt concentrations resulting in standard landfill disposal. The cyclotron assessment revealed the expected array of short and medium-lived radionuclides. Subsequent calculations suggest that meaningful levels residual activity will have decayed virtually to background after 15 years, with the total residual activity of the entire cyclotron dropping below 37 MBq (1 mCi).

    A small cyclotron has been considered for the use of biomedical accelerator mass spectrometer (BAMS). Over a decade ago a few cyclotrons had been constructed and tested for AMS, but technical problems of instability and poor transmission efficiency caused to discontinue further developments. The major reason of the demise of cyclotron AMS was the dominance of commercial Tandem-based AMS facilities. Now BAMS may ask for more compact system, and perhaps using positive ions to accelerate isotope tracers is a favorable feature. The design of a cyclotron to meet the requirements of BAMS has been performed by adopting a compact magnet with high stability and a flat-topping rf system to increase transmission efficiency.

    2002-01-01

    Aim: Describe the experience of the first PET-Cyclotron Center in Latin America. Demonstrate the viability of running a PET Center in Argentina despite the economic crisis. Materials and Methods: For this study, we used a UGM/GE Quest 250 PET scan, a RDS 112 cyclotron and a Radiosynthesis Laboratory installed at the (FUESMEN) Nuclear Medicine School Foundation, located in Mendoza City, in the middle-west of Argentina. From January 1999 to March 2002, 741 studies were obtained, 731 were 18 FluorDeoxyGlucose-PET studies and 10 phantoms for calibration purposes. We used acquisition and imaging processing standard protocols, as well as research protocols designed according to the pathology under investigation. To better correlate anatomical and functional images, we used fusion techniques with (CT) Computed Tomography in some (WB) whole-body PET scans. Results: A total of 731 patients were retrospectively analyzed and classified according to statistics variables such as: 1-sex: 317 women and 414 men, 2-type of scan: 439 WB cases, 267 brain studies and 25 cardiac. From this data we divided them as PET indications and resulted in 17 cases as healthy volunteers, 422 oncological cases, 267 neurological studies and 25 cardiac for myocardial viability. According to the origin they were classified as patients coming from Mendoza 544, Buenos Aires 112, other argentine provinces 60 and foreign (Chile, Brazil and Uruguay) 15 cases. In terms of billing, 181 studies were done free of charge, 95 under research protocols were also done free of charge and 451 were charged. Conclusion: Not only the economical and political factors play an important role limiting the advances of PET Imaging in Latin America, but also the lack of a neighboring cyclotron that circumscribe many hospitals to have access to the radiopharmaceutical agent. FUESMEN was established in 1991 by three governmental entities: the (CONEA) National Commission of Atomic Energy, the (UNC) National University of Cuyo and

    Modern Medical Cyclotrons use intense beams of high energy protons or deuterons to produce large activities of short and medium lived radionuclides. After continuous operation for prolonged periods the Cyclotron components become activated through various nuclear interactions therefore, the risk of personal radiation hazard while handling such activated cyclotron components is high. This paper describes all operational aspects of the Health Physics service evolved during the first preventative maintenance program of the Australian National Medical Cyclotron, which took place in June 1993. 5 refs., 3 tabs., 2 figs

    Ion trajectories through a spiral inflector are analyzed. In the case of a uniform magnetic field, it is shown that the central trajectory can be expressed as a simple analytical form, which includes all the inflector types already known. By using a curvilinear coordinate along the central trajectory, the equations of motion of non-central ions are modified to describe the ion motion in the transverse and longitudinal planes. A method is presented to expand the electric potential around the central trajectory to calculate the electric field to be used in the equations of motion. In the method, an electric potential thus obtained is used instead of the electric field, which guarantees the energy conservation of the ions through the inflector. Numerical studies have been carried out for design of an inflector for the SF cyclotron at the Institute for Nuclear Study, University of Tokyo. (author)

  5. Use of cyclotrons in medical research: Past, present, future

    Smathers, James B.; Myers, Lee T.

    1985-05-01

    The use of cyclotrons in medical research started in the late 1930s with the most prominent use being neutron irradiation in cancer therapy. Due to a lack of understanding of the biological effect of neutrons, the results were less than encouraging. In the 1940s and 1950s, small cyclotrons were used for isotope production and in the mid 60s, the biological effect of neutrons was more thoroughly studied, with the result that a second trial of neutron therapy was initiated at Hammersmith Hospital, England. Concurrent with this, work on the use of high energy charged particles, initially protons and alphas, was initiated in Sweden and Russia and at Harvard and Berkeley. The English success in neutron therapy led to some pilot studies in the USA using physics cyclotrons of various energies and targets. These results in turn lead to the present series of machines presently being installed at M.D. Anderson Hospital (42 MeV), Seattle (50 MeV) and UCLA (46 MeV). The future probably bodes well for cyclotrons at the two extremes of the energy range. For nuclear medicine the shift is away from the use of multiple isotopes, which requires a large range of particles and energies to 11C, 13N, 15O, and 18F, which can be incorporated in metabolic specific compounds and be made with small 8-10 MeV p+ "table top" cyclotrons. For tumor therapy machines of 60 MeV or so will probably be the choice for the future, as they allow the treatment of deep seated tumors with neutrons and the charged particles have sufficient range to allow the treatment of ocular tumors.

  6. Study of axial injection of polarized protons into the grenoble cyclotron

    1969-01-01

    By injecting ions axially into a cyclotron, it is possible to accelerate particles (polarized particles, heavy ions, etc...) obtainable only with difficulty when an internal ion source is used. In this work, after justifying the choice of an axial injection device equipped with a 'pseudo-cylindrical' deflector for the Grenoble cyclotron, we study theoretically the principle of such a detector, the choice of its parameters, and the effect of this choice on the conditions of acceleration of the beam by the cyclotron. From the experimental point of view, this report describes two operations which made it possible to check that the chosen injection device operated satisfactorily, qualitatively initially (electron model), then quantitatively (proton model). In conclusion, we believe that the Grenoble cyclotron thus equipped will be able to provide a relatively dense beam of polarized protons. (author) [fr

    The Beijing Radioactive Ion-beam Facility project is being constructed by BRIF division of China Institute of Atomic Energy. In this project, a 100 MeV high intensity compact proton cyclotron is built for multiple applications. The first successful beam extraction of CYCIAE-100 cyclotron was done in the middle of 2014. The extracted proton beam energy is 100 MeV and the beam current is more than 20 μA. The RF system of the CYCIAE-100 cyclotron includes two half-wavelength cavities, two 100 kW tetrode amplifiers and power transmission line systems (all above are independent from each other) and two sets of Low Level RF control crates. Each set of LLRF control includes an amplitude control unit, a tuning control unit, a phase control unit, a local Digital Signal Process control unit and an Advanced RISC Machines based EPICS IOC unit. These two identical LLRF control crates share one common reference clock and take advantages of modern digital technologies (e.g. DSP and Direct Digital Synthesizer) to achieve closed loop voltage and phase regulations of the dee-voltage. In the beam commission, the measured dee-voltage stability of RF system is better than 0.1% and phase stability is better than 0.03°. The hardware design of the LLRF system will be reviewed in this paper.

    Material Science, being an interdisciplinary field, plays important roles in nuclear science. These applications are seen in weaponry, armoured vehicles, accelerator structure and development, semiconductor detectors, nuclear medicine and many more. Present study presents the applications of some metals in nuclear medicine (radioisotope production). The charged-particle-induced nuclear reactions by using cyclotrons or accelerators have become a very vital feature of the modern nuclear medicine. Realising the importance of excitation functions for the efficient production of medical radionuclides, some very high purity holmium metals are generally prepared or purchased for bombardment in nuclear accelerators. In the present work, various methods to obtain pure holmium for radioisotope production have been discussed while also presenting details of our present studies. From the experimental work of the present studies, some very high purity holmium foils have been used in the work for a comprehensive study of residual radionuclides production cross-sections. The study was performed using a stacked-foil activation technique combined with γ-ray spectrometry. The stack was bombarded with 50.4 MeV alpha particle beam from AVF cyclotron of RI Beam Factory, Nishina Centre for Accelerator-Based Science, RIKEN, Japan. The work produced thulium radionuclides useful in nuclear medicine.

    Since July 1991 the Radiopharmaceutical Division of the Australian Nuclear Science and Technology Organisation (ANSTO) operates a 30 MeV H'- ion Medical Cyclotron (Model; CYCLONE 30, Manufacturer: Ion Beam Applications, Louvain La Neuve, Belgium). During routine isotope production operations at the cyclotron a thick copper substrate plate electroplated with thin layer of selected enriched target material are bombarded with 30 MeV proton beam current up to 450 μA. The nuclear reaction of protons with the copper atoms result in the reduction of prompt evaporation neutrons with a peak energy of ∼ 1.8 MeV. These evaporation neutrons slow down via multiple collisions with the concrete shielding walls of the target cave, bounce back to the,interior space of the cave activating the cyclotron parts, beam tube components and other utilities installed in the irradiation cave. After the completion of 60 hour isotope production run, gamma dose equivalent rates of ∼10 5 μSvh -1 were measured at contact with the target irradiation stations and beam collimators. Evidently, these gamma rays emitted from the activated cyclotron components impose crucial radiation exposure hazard problems for the cyclotron maintenance technicians. Experiments had been carried out in order to identify the specific pathways of cyclotron component activation and to assess the probable personnel radiation exposure during handling of the activated cyclotron parts. The cool-down (radioactive decay) of the activated cyclotron components was estimated experimentally at different target bombardment conditions using the wall mounted gamma area monitors interfaced to the Health Physics Data Acquisition System. The gamma dose equivalent rates at contact with various locations of interest at the target irradiation station and at the typical work areas of the maintenance personnel were carefully recorded with a radiation (gamma) survey instrument during the three years operation period of the cyclotron.

    This book tells the story of the Swiss Institute for Nuclear Research (SIN). The institute was founded in 1968 and became part of the Paul Scherrer Institute (PSI) in 1988. Its founding occurred at a time when physics was generally considered the key discipline for technological and social development. This step was unusual for a small country like Switzerland and showed courage and foresight. Equally unusual were the accomplishments of SIN, compared with similar institutes in the rest of the world, as well as its influence on Swiss, and partially also on international politics of science. That this story is now available in a widely understandable form is due to the efforts of some physicists, who took the initiative as long as contemporary witnesses could still be questioned. As is usually the case, official documents always show just an excerpt of what really happened. An intimate portrayal of people who contributed to success requires personal memories. This text relies on both sources. In addition, the e...

    Malaysia desire to have a cyclotron for nuclear medical use came into realisation recently with the establishment of a PET/Cyclotron Facility at Putrajaya Hospital. The testing and commissioning of the cyclotron, hot cells, QC equipment and PET/CT started on March 27, culminating in the first patient to be injected on May 10 2006. Three other patients were to be followed on May 15. The patients from both the Kuala Lumpur and Putrajaya Hospital were pre-selected by physicians from these hospitals. The 18 MeV cyclotron is capable of generating 16.4 MeV protons and 8.4 MeV deuterons. The cyclotron at Putrajaya has three targets (2 liquid and 1 gas) and is capable of producing 18 F-FDG and 18 F-DOPA. To complement this, the facility has 2 modules for FDG synthesis, 1 for F-DOPA and 1 for nucleophilic synthesis. The facility will be GMP compliant. For the first production for human use, the water-18 target was irradiated for 50 minutes at 20 mA to produce 1.3 Ci of F-18. At the end of synthesis, the activity of the FDG obtained was 600 mCi. The product was then injected to a 26-year-old female, with a suspected adenocarcinoma. (Author)

    A superconducting magnet for use in an electron cyclotron resonance ion source was developed at the Korea Basic Science Institute. The superconducting magnet is comprised of three solenoids and a hexapole magnet. According to the design value, the solenoid magnets can generate a mirror field, resulting in axial magnetic fields of 3.6 T at the injection area and 2.2 T at the extraction region. A radial field strength of 2.1 T can also be achieved by hexapole magnet on the plasma chamber wall. NbTi superconducting wire was used in the winding process following appropriate techniques for magnet structure. The final assembly of the each magnet involved it being vertically inserted into the cryostat to cool down the temperature using liquid helium. The performance of each solenoid and hexapole magnet was separately verified experimentally. The construction of the superconducting coil, the entire magnet assembly for performance testing and experimental results are reported herein.

    1995-12-01

    The plasma separation process by ion cyclotron resonance heating (ICRH) is studied both theoretically and experimentally on two devices: the first one called ERIC (Ion Cyclotron Resonance Experiment) at Saclay (France) [P. Louvet, Proceedings of the 2nd Workshop on Separation Phenomena in Liquids and Gases, Versailles, France, 1989, edited by P. Louvet, P. Noe, and Soubbaramayer (Centre d'Etudes Nucléaires de Saclay and Cité Scientifique Parcs et Technopoles, Ile de France Sud, France, 1989), Vol. 1, p. 5] and the other one named SIRENA at the Kurchatov Institute, Moscow, Russia [A. I. Karchevskii et al., Plasma Phys. Rep. 19, 214 (1993)]. The radio frequency (RF) transversal magnetic field is measured by a magnetic probe both in plasma and vacuum and its Fourier spectrum versus the axial wave number kz is obtained. These results are in agreement with the electromagnetic (EM) field calculation model based on resolution of Maxwell equations by a time-harmonic scheme studied here. Various axial boundary conditions models used to compute the EM field are considered. The RF magnetic field is weakly influenced by the plasma while the electric field components are strongly disturbed due to space-charge effects. In the plasma the transversal electric field is enhanced and the kz spectrum is narrower than in vacuum. The calculation of the resonant isotope heating is made by the Runge-Kutta method. The influence of ion-ion collisions, inhomogeneity of the static magnetic field B0, and the RF transversal magnetic field component on the ion acceleration is examined. These results are successfully compared with experiments of a minor isotope 44Ca heating measurements, made with an energy analyzer.

    In 2003, as a national and European premiere, the Fueling Machine Head no. 4 (F/M) for the Nuclear Power Plant Cernavoda Unit 2 (NPP) was successfully tested at the Institute for Nuclear Research Pitesti (INR). In 2005, the second Fueling Machine (no. 5) has tested for the Nuclear Power Plant Cernavoda Unit 2. The Institute's main objective is to develop scientific and technological support for the Romanian Nuclear Power Program. Testing the Fueling Machines at INR Pitesti is part of the overall program to assimilate the CANDU technology in Romania. To perform the tests of these machines at INR Pitesti, a special testing rig has built being available for this goal. Both the testing rig and staff had successfully assessed by the AECL representatives during two missions. There was a delivery contract between GEC Canada and Nuclear Power Plant Cernavoda - Unit 2 to provide the Fueling Machines no. 4 and no. 5 in Romania before testing activity. As a first conclusion, the Institute for Nuclear Research Pitesti has the facilities, the staff and the experience to perform possible co-operations with any CANDU Reactor owner

    Sudlitz, K

    1999-01-01

    Cusp type, 10 GHz ECRIS has been built and tested earlier. For obtaining intensive beams, more relevant for cyclotron, cusp geometry has been replaced by hexapole. Discharge chamber (stainless steel, 50 mm diameter, 250 mm long) is an extension of a coaxial line, feeding RF (9,6 GHz, up to 200 W) to the plasma. The NdFeB hexapole (0,52 T on the surface) has been used. The axial magnetic field is created by water cooled coils. The axial injection line dedicated to K160 isochronous heavy ion cyclotron has been constructed. The line consists of Glaser lenses, double focusing magnet, solenoid and mirror type inflector. The system provides sufficient transmission of the beam from ECR ion source to the firsts orbits of the cyclotron for m/q ranging from 7 to 2. After successful initial tests which were done in July 1997 the ECRIS serves as an external source for Warsaw Cyclotron.

    Electron cyclotron heating (ECH) is one of the intense methods of plasma heating, and which utilizes the collisionless electron-cyclotron-resonance-interaction between the launched electromagnetic waves (called electron cyclotron waves) and electrons which are one of the constituents of the high temperature plasmas. Another constituent, namely the ions which are subject to nuclear fusion, are heated indirectly but strongly and instantly (in about 0.1 s) by the collisions with the ECH-heated electrons in the fusion plasmas. The recent progress on the development of high-power and high-frequency millimeter-wave-source enabled the ECH experiments in the middle size tokamaks such as JFT-2M (Japan), Doublet III (USA), T-10 (USSR) etc., and ECH has been demonstrated to be the sure and intense plasma heating method. The ECH attracts much attention for its remarkable capabilities; to produce plasmas (pre-ionization), to heat plasmas, to drive plasma current for the plasma confinement, and recently especially by the localization and the spatial controllability of its heating zone, which is beneficial for the fine controls of the profiles of plasma parameters (temperature, current density etc.), for the control of the magnetohydrodynamic instabilities, or for the optimization/improvement of the plasma confinement characteristics. Here, the present status of the ECH studies on tokamak plasmas are reviewed. (author)

    Current conditions related to the nuclear and radiation safety in the Vinca Institute of Nuclear Sciences, Belgrade, Serbia and Montenegro are the result of the previous nuclear programs in the former Yugoslavia and strong economic crisis during the previous decade. These conditions have to be improved as soon as possible. The process of establishment and initialisation of the Vinca Institute Nuclear Decommissioning (VIND) Program, known also as the 'Green Vinca' Program supported by the Government of the Republic Serbia, is described in this paper. It is supposed to solve all problems related to the accumulated spent nuclear fuel, radioactive waste and decommissioning of RA research reactor. Particularly, materials associated to the RA reactor facility and radioactive wastes from the research, industrial, medical and other applications, generated in the previous period, which are stored in the Vinca Institute, are supposed to be proper repackaged and removed from the Vinca site to some other disposal site, to be decided yet. Beside that, a research and development program in the modern nuclear technologies is proposed with the aim to preserve experts, manpower and to establish a solid ground for new researchers in field of nuclear research and development.

  4. Report of the consultants' meeting on target and processing technologies for cyclotron production of radionuclides

    International Nuclear Information System (INIS)

    1999-11-01

    Cyclotron produced radionuclides are used routinely for the diagnosis of a wide variety of diseases. Recently a number of radionuclides available from cyclotrons have been proposed for use in radiotherapy. In fact Pd-103 has become routinely available in some parts of the world for incorporation into brachytherapy seeds for treating prostate cancer. The consultants meeting reviewed the status of target and processing technologies associated with cyclotron production of radionuclides. The main topics of discussion included the basic nuclear data that is crucial to the production of the desired radionuclides, gas and solid target systems, the automated chemical processing units, the Good Manufacturing Practices (GMP) required in order to use these radionuclides in human patients in a safe and efficacious manner and a review of possible candidate nuclides that show promise for use in Nuclear Medicine in the near future. Advances in the preparation of solid targets using electroplating technology has created the possibility of preparing targets capable of operating at very high beam currents which would make the production of large quantities of SPECT agents possible at cyclotron facilities throughout the world. Recognising the needs of the developing countries which have established cyclotron facilities, the consultants focussed on how to provide the technology for preparing solid targets that could be used in the existing facilities. While solid target technology can be used for many radionuclides the report concentrated on several key radionuclides, which are of current importance or show potential for use in the near future. Tl-201 is currently used for cardiac profusion studies throughout the world. New target preparation techniques could potentially make many of the member states self sufficient in the production of this nuclide. I-123 has tremendous potential because of the near ideal photon energy for SPECT cameras and its well-understood chemistry. However, it

    2014-01-01

    The scientific design of a 14-MeV H - compact superconducting cyclotron for producing of the 18 F and 13 N isotopes has been developed. Main requirements to the facility as a medical accelerator are met in the design. In particular, the main requirement for the cyclotron was the smallest possible size due to the superconducting magnet. The calculations show that the proposed cyclotron allows extracted beam intensity over 500 μA. To increase system reliability and production rates, an external H - ion source is applied. The choice of the cyclotron concept, design of the structure elements, calculation of the electromagnetic fields and beam dynamics from the ion source to the extraction system were performed.

    The UK demand for nuclear skills and research requirements is showing signs of a significant upturn. More capacity is being needed to support the UK's national programmes on clean-up and decommissioning, keeping the nuclear option open, and longer term advanced reactors technology. In response to this, The University of Manchester has launched the Dalton Nuclear Institute. The Institute is working with government and industry to strengthen and develop the UK's strategic nuclear skills base in the university sector. The Institute's scope covers the broad entirety of the UK's nuclear requirements spanning reactors, fuel cycles, decommissioning, disposal, social policy and regulation, and with connections into nuclear medicine and fusion. The rational behind the setting up of the Dalton Nuclear Institute including its research and education strategies are explained below, together with a description of the areas of current strength and the areas where major university investment is being targeted to uplift UK capacity and infrastructure. A big driver is also to forge links with other world leading centres internationally that will complement Manchester's in house capability. In the UK, the Dalton Nuclear Institute is working in partnership with Nexia Solutions and the NDA (Nuclear Decommissioning Authority) to match the Institute's plans with end-user industry and sector requirements. A key driver is to maximize the utilisation of the UK's specialist research facilities, notably the new Sellafield Technology Centre in West Cumbria. Discussions are underway with Nexia Solutions and the NDA to grant academic access for the Dalton Nuclear Institute and its collaborators to the Sellafield Technology Centre, to utilize it along the lines akin to a 'teaching hospital' model. The paper also explains the steps Dalton has taken by setting up and leading a consortium with ten other higher education providers in the UK, to launch a national programme for postgraduate

  10. Nuclear-safety institution in France: emergence and development

    International Nuclear Information System (INIS)

    Vallet, B.M.

    1986-01-01

    This research work examines the social construction of the nuclear-safety institution in France, and the concurrent increased focus on the nuclear-risk issue. Emphasis on risk and safety, as primarily technical issues, can partly be seen as a strategy. Employed by power elites in the nuclear technostructure, this diverts emphasis away from controversial and normative questions regarding the political and social consequences of technology to questions of technology that appear to be absolute to the technology itself. Nuclear safety, which started from a preoccupation with risk related to the nuclear energy research and development process, is examined using the analytic concept of field. As a social arena patterned to achieve specific tasks, this field is dominated by a body of state engineers recognized to have high-level scientific and administrative competences. It is structured by procedures and administrative hierarchies as well as by technical rules, norms, and standards. These are formalized and rationalized through technical, economic, political, and social needs; over time; they consolidate the field into an institution. The study documents the nuclear-safety institution as an integral part of the nuclear technostructure, which has historically used the specificity of its expertise as a buffer against outside interference

    The Nuclear Physics group at the University of Tennessee, Knoxville (UTK) is involved in several aspects of heavy-ion physics including both nuclear structure and reaction mechanisms. While the main emphasis is on experimental problems, the authors have maintained a strong collaboration with several theorists in order to best pursue the physics of their measurements. During the last year they have had several experiments at the ATLAS at Argonne National Laboratory, the GAMMASPHERE at the LBL 88 Cyclotron, and with the NORDBALL at the Niels Bohr Institute Tandem. Also, they continue to be very active in the WA93/98 collaboration studying ultra-relativistic heavy ion physics utilizing the SPS accelerator at CERN in Geneva, Switzerland and in the PHENIX Collaboration at the RHIC accelerator under construction at Brookhaven National Laboratory. During the last year their experimental work has been in three broad areas: (1) the structure of nuclei at high angular momentum, (2) the structure of nuclei far from stability, and (3) ultra-relativistic heavy-ion physics. The results of studies in these particular areas are described in this document. These studies concentrate on the structure of nuclear matter in extreme conditions of rotational motion, imbalance of neutrons and protons, or very high temperature and density. Another area of research is heavy-ion-induced transfer reactions, which utilize the transfer of nucleons to states with high angular momentum to learn about their structure and to understand the transfer of particles, energy, and angular momentum in collisions between heavy ions

    2005-09-01

    On August 8, 2001, Lawrence Berkeley National Laboratory celebrated the centennial of the birth of its founder (and namesake), Ernest Orlando Lawrence. For the occasion, many speeches were given and old speeches were remembered. We recall the words of the late Luis Alvarez, a Nobel Laureate and one of the Lawrence's closest colleagues: ''Lawrence will always be remembered as the inventor of the cyclotron, but more importantly, he should be remembered as the inventor of the modern way of doing science''. J. L. Heilbron and R. W. Seidel, in the introduction of their book, ''Lawrence and His Laboratory'' stated, ''The motives and mechanisms that shaped the growth of the Laboratory helped to force deep changes in the scientific estate and in the wider society. In the entrepreneurship of its founder, Ernest Orlando Lawrence, these motives, mechanisms, and changes came together in a tight focus. He mobilized great and small philanthropists, state and local governments, corporations, and plutocrats, volunteers and virtuosos. The work they supported, from astrophysics and atomic bombs, from radiochemistry to nuclear medicine, shaped the way we observe, control, and manipulate our environment.'' Indeed, all over the civilized world, the ways we do science changed forever after Lawrence built his famed Radiation Laboratory. In this editorial, we epitomize his legacy of changing the way we do medicine, thereby affecting the health and well being of all humanity. This year marks the 75th anniversary of the invention of the cyclotron by Ernest Orlando Lawrence at the University of California at Berkeley. Lawrence conceived the idea of the cyclotron early in 1929 after reading an article by Rolf Wideroe on high-energy accelerators. In the spring of 1930 one of his students, Nels Edlefsen, constructed two crude models of a cyclotron. Later in the fall of the same year, another student, M. Stanley Livingston

    Although no longer on the high energy frontier, the cyclotron field is still a major scientific growth area. Its progress is highlighted at the international conference on cyclotron design, development and utilization held at intervals of about three years, under the auspices of the International Union of Pure and Applied Physics (IUPAP). Vancouver, surrounded by mountains, water and some cyclotrons, provided a pleasant setting for the 13th Conference, held last summer. With over 200 cyclotrons in operation around the world, the attendance, 241 delegates and 26 industrial exhibitors, was a near record, reflecting the flourishing state of the field. The early sessions covered the initial operation of new or upgraded cyclotron facilities. Major facilities completed since the previous Conference in Berlin in May 1989 included the 400 MeV ring cyclotron at Osaka, the U400M cyclotron at Dubna which will be coupled to the U400 to give 20 MeV nucléon uranium beams, the 130 MeV cyclotron at Jyvaskyla (in Finland, the furthest north!), the 110 MeV JAERI machine in Japan, and the 65 MeV proton therapy cyclotron in Nice. Among the facility upgrades were the KFA cyclotron at Julich which will inject the 2.5 GeV storage ring COSY, and the addition of an FM mode to the K=200 CW mode at Uppsala to give protons up to 180 MeV. The impressive current of 1.5 mA at 72 MeV obtained from the PSI Injector II will soon be injected into the 590 MeV ring

    An ion cyclotron spectrometer may include a vacuum chamber that extends at least along a z-axis and means for producing a magnetic field within the vacuum chamber so that a magnetic field vector is generally parallel to the z-axis. The ion cyclotron spectrometer may also include means for producing a trapping electric field within the vacuum chamber. The trapping electric field may comprise a field potential that, when taken in cross-section along the z-axis, includes at least one section that is concave down and at least one section that is concave up so that ions traversing the field potential experience a net magnetron effect on a cyclotron frequency of the ions that is substantially equal to zero. Other apparatuses and a method for performing ion cyclotron spectrometry are also disclosed herein.

    1986-01-01

    The NATO Advanced Study Institute "New Vistas in Electro-Nuclear Physics" was held in Banff, Alberta, Canada from August 22 to September 4, 1985. This volume con­ tains the lecture notes from that Institute. The idea to organize this Institute coincided with the award of funding for a pulse stretcher ring at the University of Saskatchewan's Linear Accelerator Laboratory. This together with the high level of interest in electron accelerators worldwide convinced us that it was an appropriate time to discuss the physics to be learned with such machines. In particular that physics which requires high energy and/or high duty cycle accelerators for its extraction was intended to be the focus of the Institute. Thus the scope of the lec­ tures was wide, with topics ranging from the structure of the trinucleons to quark models of nucleons, QCD, and QHD. The theme however was that we are just trying to under­ stand the nucleus and that the electromagnetic probe can serve as a powerful tool in such a quest.

  20. Low energy cyclotron for radiocarbon dating

    Welch, J.J.

    1984-12-01

    The measurement of naturally occurring radioisotopes whose half lives are less than a few hundred million years but more than a few years provides information about the temporal behavior of geologic and climatic processes, the temporal history of meteoritic bodies as well as the production mechanisms of these radioisotopes. A new extremely sensitive technique for measuring these radioisotopes at tandem Van de Graaff and cyclotron facilities has been very successful though the high cost and limited availability have been discouraging. We have built and tested a low energy cyclotron for radiocarbon dating similar in size to a conventional mass spectrometer. These tests clearly show that with the addition of a conventional ion source, the low energy cyclotron can perform the extremely high sensitivity 14 C measurements that are now done at accelerator facilities. We found that no significant background is present when the cyclotron is tuned to accelerate 14 C negative ions and the transmission efficiency is adequate to perform radiocarbon dating on milligram samples of carbon. The internal ion source used did not produce sufficient current to detect 14 C directly at modern concentrations. We show how a conventional carbon negative ion source, located outside the cyclotron magnet, would produce sufficient beam and provide for quick sampling to make radiocarbon dating milligram samples with a modest laboratory instrument feasible

  1. Mapping of the flux and estimate of the radiation source term of neutron fields generated by the GE PETtrace-8 cyclotron

    2017-01-01

    The use of spectrometric techniques in a cyclotron facility is strongly advised for the complete characterization of the neutron radiation field. In recent years, several studies of neutron spectrometry have been carried out at the Cyclotron of the Development Center of Nuclear Technology (CDTN). The main objective of this work is to propose a methodology for mapping of the flux and estimate of the radiation source term of neutron fields generated by the GE PETtrace-8 cyclotron. The method of neutron activation analysis with gold, indium and nickel activation foils was used to measure the activities induced at specific points in the cyclotron bunker. The irradiations of the activation foils were performed using the intermittent irradiation method to optimize the radiation field during 18 F production. The study of the neutron spectrum was performed using three radiation source terms. The first source term was constructed based on data provided by the cyclotron manufacturer using the neutron cross sections of the ENDF/B-VII library. The other two were proposed considering the irradiation process used in the routine of 18 F production. Both radiation source terms used the LA150H proton cross sections and for the 18 O, the cross sections of the physical model CEM03 (Cascade-exciton model) and TENDL (TALYS-based Evaluated Nuclear Data Library) were used. The results of the source terms in relation to the experimental results, in terms of neutron fluence rates, reaction rates and dose equivalent rates, showed that are in the same order of magnitude as those obtained by Ogata et al, Fujibuchi et al, and Gallerani et al., for the same cyclotron; and by Mendez et al. for a different manufacturing cyclotron. The models of the proposed radiation source terms were validated to obtain the spectra generated during the 18 F production when water enriched at 18 O is bombarded with a proton beam of 16.5 MeV. Finally, the model of the LA150H - TENDL - 2015 radiation source term is

    Mukherjee, B.

    2002-01-01

    Full text: Modern Medical Cyclotrons produce a variety of short-lived positron emitting PET radioisotopes, and as a result are the source of intense neutron and gamma radiations. Since such cyclotrons are housed within hospitals or medical clinics, there is significant potential for un-intentional exposure to staff or patients in proximity to cyclotron facilities. Consequently, the radiological hazards associated with Cyclotrons provide the impetus for an effective radiological shielding and continuous monitoring of various radiation levels in the cyclotron environment. Management of radiological hazards is of paramount importance for the safe operation of a Medical Cyclotron facility. This work summarised the methods of shielding calculations for a compact hospital based Medical Cyclotron currently operating in Canada, USA and Australia. The design principle and operational history of a real-time health physics monitoring system (Watchdog) operating at a large multi-energy Medical Cyclotron is also highlighted

RA research reactor, which extended shutdown stage took almost 18 years, spent nuclear fuel from the RA operation in the water pools within the reactor building and inadequate storage facilities for the low and intermediate radioactive wastes at the Vinca site are the main safety problems that have to be solved. To solve the problems mentioned above, a new 'Vinca Nuclear Decommissioning (VIND) Program' is initiated in the Vinca Institute during 2002. The Program team is assembled from about 60 experts from the Institute and relevant organisations. The Program, known also as the G reen Vinca , will be supported, besides the government funding and expected donation from foreign institutions, by experts' help from the IAEA. The necessary equipment will be obtained through the technical assistance from the IAEA. Close co-operation of the team members with experts and relevant companies from nuclear developed countries is expected. (author)

    The resonators with the conductors ramified form for cyclotrons are systematized and separated into the self-contained class - the ramified resonators for cyclotrons (Carr). The ramified resonators are compared with the quarter-wave and half-wave nonramified resonators, accomplished from the transmitting lines fragments. The CRR are classified into two types: ones with the additional structural element, switched in parallel and in series. The CRR may include several additional structural elements. The CRR calculations may be concluded by analytical methods - the method of matrix calculation or the method of telegraph equations and numerical methods - by means of the ISFEL3D, MAFIA and other programs [ru

    Full text: Medical cyclotron is a particle accelerator used in producing short lived radioisotopes such as 18 F, 11 C, 15 O, 13 N, 18 F-2 gas etc. Positron Emission Tomography (PET) is a nuclear imaging modality that has rapidly gained favour. 18 F-FDG is the most widely used radiopharmaceutical with a half-life of 109.8 min. Having more than five years experience in this field we face lots of emergency conditions in the medical cyclotron facility. On the basis of harm we have divided in to three categories i.e. Harm of (a) working personnel, (b) Equipment and (c) environment. Radioactive gas leak and Target foil rupture is considered as the major emergency situations during medical cyclotron operations because there is a potential of over exposure to the working personnel. Radiation protection survey of a self-shielded medical cyclotron installation was carried out during normal and emergency conditions. It is found that the induced activity in the target foil increases with its successive usages. Recommendations have also been made to reduce personal exposure while handling the radioactive gas leak and target foil rupture conditions

  12. Recent achievements in Tc-99m radiopharmaceutical direct production by medical cyclotrons.

    99m Tc is the most commonly used radionuclide in the field of diagnostic imaging, a noninvasive method intended to diagnose a disease, assess the disease state and monitor the effects of treatments. Annually, the use of 99m Tc, covers about 85% of nuclear medicine applications. This isotope releases gamma rays at about the same wavelength as conventional X-ray diagnostic equipment, and owing to its short half-life (t ½  = 6 h) is ideal for diagnostic nuclear imaging. A patient can be injected with a small amount of 99m Tc and within 24 h almost 94% of the injected radionuclide would have decayed and left the body, limiting the patient's radiation exposure. 99m Tc is usually supplied to hospitals through a 99 Mo/ 99m Tc radionuclide generator system where it is produced from the β decay of the parent nuclide 99 Mo (t ½  = 66 h), which is produced in nuclear reactors via neutron fission. Recently, the interruption of the global supply chain of reactor-produced 99 Mo, has forced the scientific community to investigate alternative production routes for 99m Tc. One solution was to consider cyclotron-based methods as potential replacement of reactor-based technology and the nuclear reaction 100 Mo(p,2n) 99m Tc emerged as the most worthwhile approach. This review reports some achievements about 99m Tc produced by medical cyclotrons. In particular, the available technologies for target design, the most efficient extraction and separation procedure developed for the purification of 99m Tc from the irradiated targets, the preparation of high purity 99m Tc radiopharmaceuticals and the first clinical studies carried out with cyclotron produced 99m Tc are described.

    Full text: Compact, low energy, high current Medical Cyclotrons are now primarily used to produce large activities of short lived, neutron deficient, positron- emitting radioisotopes. These isotopes constitute the key ingredients of important PET (Positron Emission Tomography) radiopharmaceuticals used in diagnostic nuclear medicine. The PET-radioisotope producing Medical Cyclotrons are now increasingly installed in modern urban hospitals in many countries of the world. Modern Medical Cyclotrons run at a very high beam current (∼100-200 micro Amp) level and thereby produce intense fields of parasitic gamma rays and neutrons, causing the activation of cyclotron components, ambient air and radiation exposure to patients and members of the public. This report highlights the important operational aspects and the characteristics of the radiation fields produced by Medical Cyclotrons. The pathways of personnel radiation exposure are also analyzed. The above information constitutes the scientific basis of a sound operational health physics service, which is manifested in an effective dose reduction and an enhanced radiological safety of the Medical Cyclotron facility within the framework of ALARA

    The requirements to characteristics of the beams used for proton therapy are considered. The operation and proposed cyclotrons for proton therapy are briefly described. The technical decisions of creation of the cyclotron with energy variation in the range 70-230 MeV and with current up to 100 nA are estimated. Taking into account the fact, that the size and cost of the cyclotron are approximately determined by the maximum proton energy, it is realistically offered to limit the maximum proton energy to 190 MeV and to elaborate a cyclotron project with a warm winding of the magnet for acceleration of H^{-} ions. The energy of the extracted protons for each run is determined by a stripped target radius in the vacuum chamber of the accelerator, and the radiation dose field for the patient is created by the external devices using the developed techniques.

  20. Accountability Feedback Assessments for Improving Efficiency of Nuclear Regulatory Institutions

    International Nuclear Information System (INIS)

    Lavarenne, J.

    2016-01-01

    The Fukushima-Daiichi Disaster demonstrated the need of assessing and strengthening institutions involved in nuclear safety, including the accountability of nuclear regulators. There are a few problems hindering the path towards a greater understanding of systems of accountability, the ensemble of mechanisms holding to account the nuclear regulator on behalf of the public. There is no consensus on what it should deliver and no systematic method of assessment exists. This poster proposes a definition of an effective accountability system and a method of assessment of institutions based on defence in depth concepts and inspired from risk-assessment techniques used in the nuclear industry. Finally it presents a simple Monte-Carlo simulation that illustrates the inner workings of the method of assessment and shows the kind of results it will be able to supply. (author)

    2017-01-01

    The dissertation consists of a construction of appropriate sustainability indicators for nuclear area innovation and research institutes in Brazil. In order to do so, the results of the construction process, as well as, the perception of the population that resides in the area surrounding this type of institute are presented and discussed. As reference for this case study, the Nuclear Technology Development Center (CDTN) was chosen. It is located in Pampulha, more specifically, on the campus of the Federal University of Minas Gerais (UFMG), Belo Horizonte, MG, Brazil. One of the methodological processes present in this research is the Delphi method, because it is the most used in the construction of indicators. Its application in this work allowed obtaining the of specialist group opinions collected through a questionnaire. Initially, sixty-nine sustainability indicators were considered. They were distributed among the environmental, economic, socio cultural and institutional dimensions, some of which were obtained through lists of indicators pointed by literature review. Other indicators were built through discussions with groups from the nuclear, environmental, economic and socio cultural areas. Among the set of indicators investigated, twenty-six were selected as being the most relevant. A questionnaire was then applied to one hundred and twenty individuals living in the vicinity of the CDTN. Discrepancies were found during the analysis the opinions of the experts in relation to sustainability dimensions proposed, as well as, indicators of the same dimensions were varied. However, the opinion of the population and the opinion of the experts had similar results. Finally, this study is the first proposal for the nuclear sector to construct this kind of indicator that takes into account the evaluation of experts and the opinion of the community that resides around these institutions.

    The Institute for Nuclear Research and Nuclear Energy is the biggest one within Bulgarian Academy of Sciences and it is a leading complex center for research and application of the nuclear physics in Bulgaria. The year 2003 was the first for the functioning of the new organization structure of INRNE consisting of 26 laboratories and 4 scientific experimental bases joined according their thematic in 7 scientific directions governed by the correspondent Expert Councils and Specialised Seminars. The scientific staff of the Institute has been worked on about 104 problems during the 2003 mainly on our traditional scientific areas, in particular, in the field of: theory of the elementary particles, field theory, atomic nuclei and quantum phenomena; experimental physics of the elementary particles, nuclear reactions, structure of atomic nuclei, cosmic rays and gamma-astrophysics at ultra high energies; neutron interactions and cross sections, physics of the fission; reactor physics, nuclear energy and nuclear safety and security ect. Now the results are already present and, as can been seen, almost half of the developments are connected with the problems of scientific support of the national nuclear energy production, radioactive waste, monitoring and management of the environment. With few exceptions, all these tasks are financially supported by national, foreign and international organizations. The fundamental end applied research results for 2003 have been accepted for publication or published in more than 300 articles in journals and proceeding of many international conferences. Large amount of these results has been obtained in close collaboration with international and foreign research centers, universities and institutions. Essential progress was obtained by the modernization of the scientific experimental bases of INRNE. The technical design project for the reconstruction of the old research reactor IRT 2000 in the new IRT 200 was successfully finished. The

    Recent progress of cyclotron ion beam development for applications in materials science and biotechnology at the ion-irradiation research facility TIARA of the Japan Atomic Energy Research Institute(JAERI) is overviewed. The AVF cyclotron in TIARA can accelerate protons and heavy ions up to 90 MeV and 27.5 MeV/n, respectively. In order to conform to the requirement of a reliable tuning of microbeam formation, the cyclotron beam current has been stabilized by controlling the temperature of the magnet yoke and pole within +/-0.5 deg. and hence by decreasing the variation of the magnetic field ΔB/B below 10-5. A heavy ion microbeam with energy of hundreds MeV is a significantly useful probe for researches on biofunctional elucidation in biotechnology. Production of the microbeam with spot size as small as 1μm by quadrupole lenses requires the energy spread of the beam ΔE/E < 2 x 10-4. In order to minimize the energy spread of the cyclotron beam, the fifth-harmonic voltage waveform has been successfully superposed on the fundamental one to make energy gain uniform

    1994-01-01

    The United Kingdom Government's Nuclear Review currently underway, addresses whether and in what form nuclear power should continue to be part of the country's power generation capability. This article sets out the response of the Institution of Nuclear Engineers to the Nuclear Review. This pro-nuclear group emphasises the benefits to be gained from diversity of generation in the energy supply industry. The environmentally benign nature of nuclear power is emphasised, in terms of gaseous emissions. The industry's excellent safety record also argues in favour of nuclear power. Finally, as power demand increases globally, a health U.K. nuclear industry could generate British wealth through power exports and via the construction industry. The Institution's view on radioactive waste management is also set out. (UK)

  3. Advances in superconducting cyclotrons at MSU

    1987-01-01

    Intensive work on superconducting cyclotrons began at MSU in late 1973 (a brief earlier study had occurred in the early 1960's) and continues vigorously at present. One large cyclotron, the ''K500'', has been operating for a number of years, a second, the ''K800'', is nearing completion, the first operating tests of its magnet having occurred at the time of the previous conference, and a third, the ''medical cyclotron'', is now also nearing completion with first operation of its magnet expected just after the present conference. These cyclotrons like other superconducting cyclotrons are all dramatically smaller than comparable room temperature machines; overall weight is typically about 1/20th of that of room temperature cyclotrons of the same energy. This large reduction in the quantities of materials is partially offset by added complexity, but finally, a net overall cost savings of 50 to 70 % typically results; as a consequence the superconducting cyclotron is widely viewed as the cyclotron of the future. The thirteen years of experience at MSU involving three of these cyclotrons, together with much important work at other laboratories, gives a rather clear view of the advantages and disadvantages of various design approaches including by now a rather significant period of long term evaluation. This paper reviews highlights of this program. (author)

    In 2003, as a national and European premiere, at the Institute for Nuclear Research Pitesti (INR), the Fueling Machine Head no.4 (F/M) for the Nuclear Power Plant Cernavoda - Unit 2 was successfully tested. In 2005, a second Fueling Machine (no.5) was tested for the Nuclear Power Plant Cernavoda - Unit 2. The Institute's main objective is to develop scientific and technological support for the Romanian Nuclear Power Program. Testing the Fueling Machines at INR Pitesti is part of the overall program to assimilate in Romania the CANDU technology. To perform the tests of these machines at INR Pitesti, a special testing rig was built and is available for this goal. Both the testing rig and staff had successfully assessed by the AECL representatives during two missions. There was a delivery contract between GEC Canada and Nuclear Power Plant Cernavoda - Unit 2 to provide the Fueling Machines no. 4 and no. 5 in Romania before testing operation. As a first conclusion, the Institute for Nuclear Research Pitesti has the facilities, the staff and the experience to perform possible co-operations with any other CANDU Reactor owner. This experience will support the next steps concerning F/M commissioning in the NPP Cernavoda - Unit 2 and also give the confidence to the end-users that the Institute's team can provide technical assistance during the operation. Also, the obtained results demonstrate that the overall refurbishment of the F/M control system in Unit 1 and Unit 2 will be possible. The paper presents: - a short description of the F/M head;- a short description of the F/M test rig; - the computer control system; - the F/M testing activities; -results and expectations. (authors)

    2004-01-01

    History of charged particle accelerators in Japan is reviewed. The nuclear reaction by an accelerator was observed first in 1934 at Taipei in Taiwan, which was a colony of Japan at that time. Before the world war II, three cyclotrons were built at Institute of Physics and Chemistry Research, Osaka University and Kyoto University. After the war, the cyclotrons were destroyed by the occupation army. The construction of accelerators was restarted at 1951, and synchrotrons, betatrons, Van de Graaff accelerators, Cockcroft-Walton accelerators as well as cyclotrons were built at various universities and institutes. To be operated and used by the nuclear physicists from all over Japan, a large-scale accelerator facility, Institute for Nuclear Study, was founded at University of Tokyo. (K.Y.)

    1984-01-01

    The applicability and limitations of the use of cyclotron light ions bombardment to simulate the effects of the neutron irradiation are presented. Light ions with energies of about 10 MeV are capable to produce homogeneous damage in specimens suitable for measuring bulk mechanical properties although their low damage rate of 10 -5 dpa.sec -1 limit the dose range to a few dpa. On the other hand, cyclotron alpha particle implantation provides a fast and convenient way of introducing helium with a minimum of side effects so that we can take advantage of this technique to get better understanding of the mechanism by which this insoluble gas produces high temperature embrittlement. Some experimental details such as dimensions and cooling techniques are described. Finally a description of the infrastructure for cyclotron alpha particle implantation and a creep-test facility of the Division of Radiation Damage at IPEN-CNEN/SP are presented. (Author) [pt

  12. Legal and Institutional Issues of Transportable Nuclear Power Plants: A Preliminary Study

    International Nuclear Information System (INIS)

    2013-01-01

    jointly the international and national actions required for ensuring the sustainability of nuclear energy through innovations in technology and/or institutional arrangements. A transportable nuclear power plant (TNPP) is a factory manufactured, transportable and relocatable nuclear power plant which, when fuelled, is capable of producing final energy products such as electricity and heat. Introducing a TNPP may require fewer financial and human resources from the host State. However, the deployment of such reactors will face new legal issues in the international context which need to be resolved to enable the deployment of such reactors in countries other than the country of origin. The objective of this report is to study the legal and institutional issues for the deployment of TNPPs, to reveal challenges that might be faced in their deployment, and to outline pathways for resolution of the identified issues and challenges in the short and long terms. It is addressed to senior legal, regulatory and technical officers in Member States planning to embark on a nuclear power programme or to expand an existing one by considering the introduction of a TNPP

    Imagine a portable medical cyclotron operated in a conventional radioactive facility at a hospital. Imagine a nurse or technician switching it on and producing isotopes at the patient’s bedside. Sounds like science fiction? Think again.   CERN has teamed up with Spain’s national scientific research centre (CIEMAT) to develop an avant-garde cyclotron to be used for Positron Emission Tomography (PET). “We plan to make a cyclotron that doesn't need an insulated building or ‘vault’: a cyclotron small enough to fit inside a hospital lift,” explains Jose Manuel Perez, who is leading the CIEMAT/CERN collaboration. “It will be the smallest possible medical cyclotron for single patient dose production and will dramatically reduce costs for hospitals.” While PET technology has transformed imaging techniques, many of its medical benefits have remained confined to highly specialised hospitals. “Studies have foun...

    2013-01-15

    Purpose: With the introduction of hybrid PET/MRI systems, it has become more likely that the cyclotron and MRI systems will be located close to each other. This study considered the interference between a cyclotron and a superconducting MRI system. Methods: Interactions between cyclotrons and MRIs are theoretically considered. The main interference is expected to be the perturbation of the magnetic field in the MRI due to switching on or off the magnetic field of the cyclotron. MR imaging is distorted by a dynamic spatial gradient of an external inplane magnetic field larger than 0.5-0.04 {mu}T/m, depending on the specific MR application. From the design of a cyclotron, it is expected that the magnetic fringe field at large distances behaves as a magnetic dipolar field. This allows estimation of the full dipolar field and its spatial gradients from a single measurement. Around an 18 MeV cyclotron (Cyclone, IBA), magnetic field measurements were performed on 5 locations and compared with calculations based upon a dipolar field model. Results: At the measurement locations the estimated and measured values of the magnetic field component and its spatial gradients of the inplane component were compared, and found to agree within a factor 1.1 for the magnetic field and within a factor of 1.5 for the spatial gradients of the field. In the specific case of the 18 MeV cyclotron with a vertical magnetic field and a 3T superconducting whole body MR system, a minimum distance of 20 m has to be considered to prevent interference. Conclusions: This study showed that a dipole model is sufficiently accurate to predict the interference of a cyclotron on a MRI scanner, for site planning purposes. The cyclotron and a whole body MRI system considered in this study need to be placed more than 20 m apart, or magnetic shielding should be utilized.

    Electron cyclotron resonance ion sources are widely used in heavy ion accelerators in the world because they are capable of producing high current beams of highly charged ions. However, the design of the Q/A selector system for these devices is challenging, because it must have a sufficient ion resolution while controlling the beam emittance growth. Moreover, this system has to be matched for a wide range of ion beam species with different intensities. In this paper, research on the Q/A selector system at the SECRAL (Superconducting Electron Cyclotron Resonance ion source with Advanced design in Lanzhou) platform both in experiment and simulation is presented. Based on this study, a new Q/A selector system has been designed for SECRAL II. The features of the new design including beam simulations are also presented.

  2. Cyclotron Phase-Coherent Ion Spatial Dispersion in a Non-Quadratic Trapping Potential is Responsible for FT-ICR MS at the Cyclotron Frequency

    Science.gov (United States)

    2018-01-01

    Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) at the cyclotron frequency instead of the reduced cyclotron frequency has been experimentally demonstrated using narrow aperture detection electrode (NADEL) ICR cells. Here, based on the results of SIMION simulations, we provide the initial mechanistic insights into the cyclotron frequency regime generation in FT-ICR MS. The reason for cyclotron frequency regime is found to be a new type of a collective motion of ions with a certain dispersion in the initial characteristics, such as pre-excitation ion velocities, in a highly non-quadratic trapping potential as realized in NADEL ICR cells. During ion detection, ions of the same m/z move in phase for cyclotron ion motion but out of phase for magnetron (drift) ion motion destroying signals at the fundamental and high order harmonics that comprise reduced cyclotron frequency components. After an initial magnetron motion period, ion clouds distribute into a novel type of structures - ion slabs, elliptical cylinders, or star-like structures. These structures rotate at the Larmor (half-cyclotron) frequency on a plane orthogonal to the magnetic field, inducing signals at the true cyclotron frequency on each of the narrow aperture detection electrodes. To eliminate the reduced cyclotron frequency peak upon dipolar ion detection, a number of slabs or elliptical cylinders organizing a star-like configuration are formed. In a NADEL ICR cell with quadrupolar ion detection, a single slab or an elliptical cylinder is sufficient to minimize the intensity of the reduced cyclotron frequency components, particularly the second harmonic.

    High efficiency cyclotron operations (up to 5200 hours of beam time a year) considerably increased the possibility to perform both fundamental and applied scientific work. There appeared possibility to accelerate protons in a wide energy range from 6 to 30 MeV and realize correspondingly the nuclear reactions up to (A, 3n). This paper reports that among different applied tasks performed at the cyclotron the special program of cyclotron production of short-lived medical radioisotopes iodine-123, thallium-201, cadmium-109 in the first place and some others to satisfy clinic needs of Alma-Ata and its region has special importance. In accordance with this program the preparation to produce iodine-123 is being held and regular production of Thallium chloride, thallium-201 pharmaceptical is started

    The design and construction of the multidetector system CACTUS is discussed, and its operation in the context of the Oslo Cyclotron is described. The multidetector system has been initiated to meet the requirements at the Oslo Cyclotron Laboratory in the experimental work on nuclear structure at high intrinsic excitation energy. The laboratory has developed a promising technique based on measuring γ-decay after single nucleon transfer reactions with the use of pγ coincidences. However, a proper interpretation of the experimental results has often been difficult due to low counting rates. One of the most important aims for the new experimental set-up has been to obtain pγ as well as pγγ coincidence spectra with high statistics. The CACTUS detector system which is mounted on the 90 o beam line of the cyclotron, consists of 28 NaI and 2 Ge detectors in combination with 8 Si particle telescopes

    The social and economic benefits of additional electrical generating capacity in lesser developed countries are unquestioned, and a case can be made from economic and environmental considerations that much of this capacity should be nuclear powered. Obstacles to the introduction of nuclear power in the developing world include lack of a technical infrastructure and capital cost. Manpower shortage also detracts from a country's ability to effectively regulate a nuclear power enterprise. Two variations on the traditional institutional methods for supplying and regulating nuclear electric power are proposed. The first would be independent international companies that would design, finance, build, operate and maintain nuclear power stations, and sell electricity to local systems. The second would be an international safety regulatory system that could offer uniform, effective regulations and enforcement of the entire nuclear power enterprise at a level consistent with accepted world standards. These proposals coupled with the modular Advanced Liquid Metal Reactor based on Integral Fast Reactor technology would make possible a safe, economically feasible nuclear power operation that could be located anywhere in the world.

By a brief historical reminder of the evolution of the radioactivity and development of nuclear science, we could see a very early interest and application of the radioactivity in the medical field. Main steps: Detection of natural radioactivity/Discovery of artificial radioactivity/First treatment of leukaemia and thyroid/First nuclear reactor/First radioisotope laboratory in hospital/First scintigraphy/First radiopharmaceutical/First cyclotron and cyclotron products/First immunoscintigraphy/Biotechnology and radioisotope/Evolution of technics [equipment for diagnosis (imaging, scintigraphy) and therapy]/Evolution of production technics and concept of products (generators of Technetium) and machines, reactor, cyclotron/Evolution of importance and interest of nuclear medicine/Creation of international association of nuclear medicine and producers (example ARPR)/Evolution of safety and pharmaceuticals regulation. After the sixties, period extremely rich in invention of products, characterized by a high fertility specially due to a non-restrictive regulation in terms of safety and pharmaceutical consideration, the evolution of technics, the importance of costs (investment, research, healthcare and the evolution of the regulations) have smoothly but continuously transformed the contexts and different actors. Consequences and facts: Rationalization and standardization of the catalogues, total integration of radiopharmaceuticals into the pharmaceutical laws, stop of nuclear research reactors, increase of number of cyclotrons, transformation of size and role of the producers and nuclear centers, risk in supply of some raw materials like Molybdenum, medical nuclear application as a worldwide business

    We analysed a period of the contemporary Brazilian history with the aim to discuss the inter-relationship between science, technology (S and T) and culture in a developing country, showing as a background for a case of study the history of the 'Instituto de Pesquisas Energeticas e Nucleares'. The history of Science and Technology, as a result of the human brain ability of innovate using the resources offered by nature, it is not only the description of successive findings carried out by talented men. It is a reflex of determined age of history as a consequence of accumulated knowledge connected also to human and cultural relationships, which together leads to the scientific and technological progress. In fact, the human brain and society march along together and can not be separated in this journey. In our study we recovered the initial steps of IPEN's outbreak; inserted its achievements in the context of the national policy for nuclear technology and evaluated how this policy was a reply of the governmental organizations to the worldwide situation. Finally, we spread the scientific ideas and technological findings of this institution, who has translate much of the life style and culture of our society. For this purposes, we analysed internal technical report series elaborated by several researchers and few testimonies. The Institution developed the fuel cycle technology, supplied radioisotopes for medical diagnosis and treatment purposes, generating economic resources for our country. The nuclear techniques are a relevant tool for researchers of this Institution applied for several purposes, including the assessment of the radioactivity levels in the environment, radioprotection, etc. Besides those applications, other techniques including the laser technology, the fuel cell, corrosion studies, etc, were implemented as a result of the improved capabilities and skills acquired during the almost 50 years of the Institute's existence.

    Full text: The last year of the twentieth-century was productive for our Department. Although the name of the Department suggests that we are all involved in investigations of nuclear reactions, in fact our activities are spread over three major domains: nuclear, atomic and material physics. Some of the projects we were involved in the last year have been realized using national facilities and accelerators, like the Van de Graaff accelerator of our Department at 69 Hoza Street, Warsaw Cyclotron U-200P of Warsaw University, and compact C30 cyclotron of our Institute at Swierk. Other projects were done abroad, using facilities of the Gesellschaft fuer Schwerionenforschung in Darmstadt, Institute de Physique Nucleaire at Orsay, and Universitaet Erlangen-Nuernberg in Erlangen. We carried out our work in close collaborations with physicists from many laboratories, Polish and foreign. - Low energy nuclear reactions. In collaboration with scientists from Ukraine experiments, using heavy ion beam provided by the Warsaw Cyclotron, were started. The aim of the experiments is to study nuclear reactions leading to the exotic light nuclei in exit channels and energy dependence of the nucleus - nucleus interaction. Efforts were made to develop a multistep direct model of nuclear reactions. In the model contributions due to the low energy collective excitations were taken into account. Good agreement with the experimental data was achieved. - Multifragmentation of relativistic heavy ions. ALADIN Collaboration studied multifragmentation reactions induced by relativistic heavy ions. The main activities of our scientists concentrated on an upgrade of the detecting system in order to replace photo multipliers with large area avalanche photodiodes in the central section of the TOF-wall. Some tests of the photodiodes manufactured by Advanced Photonix Inc. were performed using standard β - and γ-sources. - Structure of a nucleon. Decay properties of the Roper resonance were studied.

    The effects of ionizing particles on sensitive microelectronics is an important component of the design of systems as diverse as satellites and space probes, detectors for high energy physics experiments and even internet server farms. Understanding the effects of radiation on human cells is an equally important endeavor directed towards future manned missions in space and towards cancer therapy. At the 88-Inch Cyclotron at the Berkeley Laboratory, facilities are available for radiation effects testing (RET) with heavy ions and with protons. The techniques for doing these measurements and the advantages of using a cyclotron will be discussed, and the Cyclotron facilities will be compared with other facilities worldwide. RET of the same part at several facilities of varying beam energy can provide tests of the simple models used in this field and elucidate the relative importance of atomic and nuclear effects. The results and implications of such measurements will be discussed

  15. A small low energy cyclotron for radioisotope measurements

    Direct detection of 14 C by accelerator mass spectrometry has proved to be a much more sensitive method for radiocarbon dating than the decay counting method invented earlier by Libby. A small cyclotron (the ''cyclotrino'') was proposed for direct detection of radiocarbon in 1980. This combined the suppression of background through the use of negative ions, which had been used effectively in tandem accelerators, with the high intrinsic mass resolution of a cyclotron. Development of a small electrostatically-focused cyclotron for use as a mass spectrometer was previously reported but the sensitivity needed for detection of 14 C at natural abundance was not achieved. The major contributions of this work are the integration of a high current external ion source with a small flat-field, electrostatically-focused cyclotron to comprise a system capable of measuring 14 C at natural levels, and the analysis of ion motion in such a cyclotron, including a detailed analysis of phase bunching and its effect on mass resolution. A high current cesium sputter negative ion source generates a beam of carbon ions which is pre-separated with a Wien filter and is transported to the cyclotron via a series of electrostatic lenses. Beam is injected radially into the cyclotron using electrostatic deflectors and an electrostatic mirror. Axial focusing is entirely electrostatic. A microchannel plate detector is used with a phase-grated output. In its present form the system is capable of improving the sensitivity of detecting 14 C in some biomedical experiments by a factor of 10 4 . Modifications are discussed which could bring about an additional factor of 100 in sensitivity, which is important for archaeological and geological applications. Possibilities for measurements of other isotopes, such as 3 H, and 10 Be, and 26 Al, are discussed. 70 refs

    Summary form only given. Soon after the experiments at Dubna, which synthesized element 114 and made the first footprints on the beach of the "island of nuclear stability", two new superheavy elements have been discovered at the Lawrence Berkeley National Laboratory. Element 118 and its immediate decay product, element 116, were manufactured at Berkeley's 88 inch cyclotron by fusing targets of lead-208 with an intense beam of 449 MeV krypton-86 ions. Although both new nuclei almost instantly decay into lighter ones, the decay sequence is consistent with theories that have long predicted the island of stability for nuclei with approximately 114 protons and 184 neutrons. Theorist Robert Smolanczuk, visiting from the Soltan Institute for Nuclear Studies in Poland, had calculated that this reaction should have particularly favourable production rates. Now that this route has been signposted, similar reactions could be possible: new elements and isotopes, tests of nuclear stability and mass models, and a new under...

    Full text: The knowledge of the neutron spectra in a PET cyclotron is important for the optimization of radiation protection of the workers and individuals of the public. The main objective of this work is to study the source term of radiation of the GE-PET trace 8 cyclotron of the Development Center of Nuclear Technology (CDTN/CNEN) using computer simulation by the Monte Carlo method. The MCNPX version 2.7 code was used to calculate the flux of neutrons produced from the interaction of the primary proton beam with the target body and other cyclotron components, during 18F production. The estimate of the source term and the corresponding radiation field was performed from the bombardment of a H{sub 2}{sup 18}O target with protons of 75 μA current and 16.5 MeV of energy. The values of the simulated fluxes were compared with those reported by the accelerator manufacturer (GE Health care Company). Results showed that the fluxes estimated with the MCNPX codes were about 70% lower than the reported by the manufacturer. The mean energies of the neutrons were also different of that reported by GE Health Care. It is recommended to investigate other cross sections data and the use of physical models of the code itself for a complete characterization of the source term of radiation. (Author)

    By injecting ions axially into a cyclotron, it is possible to accelerate particles (polarized particles, heavy ions, etc...) obtainable only with difficulty when an internal ion source is used. In this work, after justifying the choice of an axial injection device equipped with a 'pseudo-cylindrical' deflector for the Grenoble cyclotron, we study theoretically the principle of such a detector, the choice of its parameters, and the effect of this choice on the conditions of acceleration of the beam by the cyclotron. From the experimental point of view, this report describes two operations which made it possible to check that the chosen injection device operated satisfactorily, qualitatively initially (electron model), then quantitatively (proton model). In conclusion, we believe that the Grenoble cyclotron thus equipped will be able to provide a relatively dense beam of polarized protons.

Du point de vue experimental, ce rapport decrit deux manipulations qui ont permis de verifier le bon fonctionnement du dispositif d'injection retenu, qualitativement d'abord (modele a electrons), quantitativement ensuite (maquette a protons).

  3. Realistic edge field model code REFC for designing and study of isochronous cyclotron

    1989-01-01

    The focussing properties and the requirements for isochronism in cyclotron magnet configuration are well-known in hard edge field model. The fact that they quite often change considerably in realistic field can be attributed mainly to the influence of the edge field. A solution to this problem requires a field model which allows a simple construction of equilibrium orbit and yield simple formulae. This can be achieved by using a fitted realistic edge field (Hudson et al 1975) in the region of the pole edge and such a field model is therefore called a realistic edge field model. A code REFC based on realistic edge field model has been developed to design the cyclotron sectors and the code FIELDER has been used to study the beam properties. In this report REFC code has been described along with some relevant explaination of the FIELDER code. (author). 11 refs., 6 figs

    In Japan, there are at present more than 30 PET (Positron Emission Tomography) facilities. The movements of medical insurance application to the PET diagnosis using [ 18 F] FDG (2-[ 18 F]-fluoro-2-deoxy-glucose) by the Ministry of Health and Welfare are being enhanced by PET related people. Therefore, more clinical centers using PET system are expected to be built in the near future. HM12 cyclotron was developed to meet such market demands for PET, and the prototype machine has been rent to Cyclotron Radio Isotope Center (CYRIC) of Tohoku University since Oct. 1998 for their use of clinical research with positron emitters like 11 C, 13 N, 15 O and 18 F. We got many technical data of HM12 Cyclotron on the clinical base. The data was enough to establish the reliability of HM12 system operation under the clinical condition. The first commercial product of HM12 Cyclotron was delivered to National Cancer Center in March 2000. The final performance test will be finished by the end of June 2000. (author)

    Two proton accelerators have been recently put in operation in Bern: an 18 MeV cyclotron and a 2 MeV RFQ linac. The commercial IBA 18/18 cyclotron, equipped with a specifically conceived 6 m long external beam line ending in a separate bunker, will provide beams for routine 18-F and other PET radioisotope production as well as for novel detector, radiation biophysics, radioprotection, radiochemistry and radiopharmacy developments. The accelerator is embedded into a complex building hosting two physics laboratories and four Good Manufacturing Practice (GMP) laboratories. This project is the result of a successful collaboration between the Inselspital, the University of Bern and private investors, aiming at the constitution of a combined medical and research centre able to provide the most cutting-edge technologies in medical imaging and cancer radiation therapy. The cyclotron is complemented by the RFQ with the primary goals of elemental analysis via Particle Induced Gamma Emission (PIGE), and the detection of potentially dangerous materials with high nitrogen content using the Gamma-Resonant Nuclear Absorption (GRNA) technique. In this context, beam instrumentation devices have been developed, in particular an innovative beam profile monitor based on doped silica fibres and a setup for emittance measurements using the pepper-pot technique. On this basis, the establishment of a proton therapy centre on the campus of the Inselspital is in the phase of advanced study

    Two proton accelerators have been recently put in operation in Bern: an 18 MeV cyclotron and a 2 MeV RFQ linac. The commercial IBA 18/18 cyclotron, equipped with a specifically conceived 6 m long external beam line ending in a separate bunker, will provide beams for routine 18-F and other PET radioisotope production as well as for novel detector, radiation biophysics, radioprotection, radiochemistry and radiopharmacy developments. The accelerator is embedded into a complex building hosting two physics laboratories and four Good Manufacturing Practice (GMP) laboratories. This project is the result of a successful collaboration between the Inselspital, the University of Bern and private investors, aiming at the constitution of a combined medical and research centre able to provide the most cutting-edge technologies in medical imaging and cancer radiation therapy. The cyclotron is complemented by the RFQ with the primary goals of elemental analysis via Particle Induced Gamma Emission (PIGE), and the detection of potentially dangerous materials with high nitrogen content using the Gamma-Resonant Nuclear Absorption (GRNA) technique. In this context, beam instrumentation devices have been developed, in particular an innovative beam profile monitor based on doped silica fibres and a setup for emittance measurements using the pepper-pot technique. On this basis, the establishment of a proton therapy centre on the campus of the Inselspital is in the phase of advanced study.

    Qaim, S.M.

    2002-01-01

    The types of nuclear data and their quality required in the production and application of diagnostic radionuclides are outlined. The radioactive decay data determine the suitability of a radioisotope for in vivo tracer studies, both from the imaging and internal radiation dose considerations. The nuclear reaction cross section data allow optimisation of production routes. Both reactors and cyclotrons are used for production purposes. The nuclear data needed in the two cases and their present status are discussed. Special attention is paid to radionuclides suitable for emission tomography (PET and SPECT). The controversy about reactor vs cyclotron production of the widely used sup 9 sup 9 Mo/ sup 9 sup 9 sup m Tc generator system is discussed. Some special considerations in cyclotron production of radionuclides are outlined. The need of accurate data near reaction thresholds, the constraint of available particles and their energies at a small cyclotron, the influence of increasing incident particle energy, and the formation of isomeric impurities are discussed in detail. The role of nuclear model calculations in predicting unknown data is considered. (author)

    Many countries, particularly in Europe, started with nuclear programs in the fifties of the last century. As a consequence nuclear research institutes were established, among them also the Institute Jozef Stefan (IJS) in Slovenia. The nuclear activities at the IJS were related to the development of uranium ore processing technology and technologies comprising uranium oxide and hexafluoride. After very intensive period of nuclear activities the decline began step by step due to different reasons. Various approaches of the termination and decommissioning of facilities were used. The inspectors of the Slovenian Nuclear Safety Administration (SNSA), the responsible authority, started intensive activities at the IJS at the end of 2004. All together 22 research laboratories or research units were included in the inspection program and around 50 researchers of the IJS were involved into the inspection procedures. The inspection was very intensive in the laboratories and storages where past nuclear activities took place and were later on abandoned. As a result several contaminated equipments and sites in addition to around 200 unregistered sources were found. The majority of these sources is related to past nuclear activities. The inspection program related to the terminated research activities is still in progress. The IJS immediately started with the remediation activities including the development of methodology related to decontamination of radioactive liquids. The decontamination of two nuclear laboratories and three different storages of radioactive waste at its sites is in progress. Sixty of the above mentioned sources have been already stored in the Central Interim Storage for Radioactive Waste. (author)

    Schulte, W.M.

    1978-01-01

    This thesis deals with the study of the motion of accelerated charged particles in an AVF cyclotron. This study has been done on behalf of the VICKSI- project of the Hahn-Meitner-Institut in West Berlin. A new theory is developed which facilitates an accurate description of the influence of the acceleration on the motion in the median plane of a cyclotron. The theory is applied to systems with 1 or 2 Dee electrodes, the frequency of the accelerating voltage being equal to the revolution frequency of the particles or a higher harmonic of this frequency. It turned out that the betatron oscillations in the radial phase space may be disturbed considerably as a result of the acceleration. In the theory the author makes use of the Hamilton formalism. After a number of canonical transformations a Hamilton function was found, in which the most important effects show themselves clearly. The corresponding equations of motion can be solved very quickly with the help of a simple computer program. The results of this theory are in agreement with those of extensive numerical orbit integration programmes. In this thesis attention is also devoted to the centering of the beam in the VICKSI cyclotron just after injection, the possibility to obtain single-turn extraction and the interpretation of the high frequency phase measurements.

    Education programmes in nuclear engineering and radiation protection in former Yugoslavia have been supported by comprehensive research and development and pertinent training of experts and students in the Vinca (former B oris Kidric ) Institute of nuclear sciences and abroad. Two research reactors were constructed and operated in the Vinca Institute since 1958. Adopted law on ban for NPP construction, isolation of the country due to the UN sanctions and weak economical situation deteriorated considerably the nuclear expertise in Serbia after 1989. Nuclear courses at the University were revoked, major research programmes were cancelled, RA research reactor in the Vinca Institute was shut down and many experts left the country. A novel nuclear programme related to remedial of nuclear and radiation safety in the Vinca Institute has been launched in 2003. This paper emphasizes the need for nuclear expertise, the lack of nuclear professionals to carry out the new programme, the experience gained so far and point out a possible future creative role of the Vinca Institute in education of new experts in the country and abroad.

    Particle accelerators are generators that produce beams of charged particles with energies depending on the accelerator type. The MGC-20 cyclotron is a cyclic particle accelerator used for accelerating protons, deuterons, alpha particles, and helium-3 to different energies. Main applications are isotopes production, nuclear reactions studies, and mass spectroscopy studies and other industrial applications. The cyclotron is a complicated machine depends on using a strong magnetic field and high frequency-high voltage electric field together to accelerate and bend charged particles inside the accelerating chamber. It consists of the following main parts, the radio frequency system, the main magnet with the auxiliary concentric and harmonic coils, the electrostatic deflector, and the ion source, the beam transport system, and high precision and high stability DC power supplies.To accelerate a particle to certain energy, one has to adjust the cyclotron operating parameters to be suitable to accelerate this particle to that energy. If the cyclotron operating parameters together are adjusted to accelerate a charged particle to certain energy, then these parameters together are named the operating mode to accelerate this particle to that energy. For example the operating mode to accelerate protons to 18 MeV is named the (18 MeV protons operating mode). The operating mode includes many parameters that must be adjusted together to be successful to accelerate, extract, focus, steer a particle from the ion source to the experiment. Due to the big number of parameters in the operating modes, 19 parameters have been selected in this thesis to be used in an intelligent system based on feed forward back propagation neural network to determine the parameters for new operating modes. The new intelligent system depends on the available information about the currently used operating modes.The classic way to determine a new operating mode was depending on trial and error method to

    The CYRCe cyclotron (CYclotron pour la ReCherche et l’Enseignement) is used at IPHC (Institut Pluridisciplinaire Hubert Curien) for the production of radio-isotopes for diagnostics, medical treatments and fundamental research in radiobiology. The TR24 cyclotron produced and commercialized by ACSI (Canada) delivers a 16-25 MeV proton beam with intensity from few nA up to 500 μA. The solenoidal focusing instead of existing quadrupole one is proposed in this report. The changing of the focusing elements will give the better beam matching with the acceptance of the spiral inflector of the cyclotron. The parameters of the focusing solenoid are found. Additionally, the main parameters of the bunching system are evaluated in the presence of the beam space charge. This system consists of the buncher installed in the axial injection beam line of the cyclotron. The using of the grid-less multi harmonic buncher may increase the accelerated beam current and will give the opportunity to new proton beam applications.

    2005-01-01

    The Kaiser Wilhelm Institute for Physics is best known as the place where Werner Heisenberg worked on nuclear weapons for Hitler. Although this is essentially true, there is more to the story. At the start of World War II this institute was taken over by the German Army Ordnance to be the central, but not exclusive site for a research project into the economic and military applications of nuclear fission. The Army physicist Kurt Diebner was installed in the institute as its commissarial director. Heisenberg was affiliated with the institute as an advisor at first, and became the director in 1942. Heisenberg and his colleagues, including in particular Karl-Heinz Hoecker, Carl Friedrich von Weizsaecker, and Karl Wirtz, worked on nuclear reactors and isotope separation with the clear knowledge that these were two different paths to atomic bombs [Atombomben]. However, they were clearly ambivalent about what they were doing. New documents recently returned from Russian archives shed new light on this work and the scientists' motivations. (orig.)

    Recently, the number of PET cyclotrons has increased in Korea. A cyclotron mainly produces {sup 18}F, which is used for the production of [{sup 18}F]FDG, a cancer diagnostic radiopharmaceutical. For radiation protection, the discharge control standard under the Nuclear Safety Act limits the radioactive concentration of {sup 18}F in the exhaust discharged from a nuclear power utilization facility to below 2,000 Bq m-3. However, the radioactive concentration of 18F discharged during [18F]FDG production at the cyclotron facility at Chosun University is maintained at about 1,500 Bq m{sup -3} on average, which is 75% of the concentration limit of the discharge control standard, and temporarily exceeds the standard as per the real-time monitoring results. This study evaluated the performance of the exhaust flter unit of the cyclotron facility at Chosun University by assessing the concentration of {sup 18}F in the exhaust, and an experiment was conducted on the discharge reduction, where {sup 18}F is discharged without reacting with the FDG precursors during [{sup 18}F]FDG synthesis and is immediately captured by the [{sup 18}F]FDG automatic synthesis unit. Based on the performance evaluation results of the exhaust flter at the cyclotron facility of Chosun University, the measured capture effciency before and after the flter was found to be 92%. Furthermore, the results of the discharge reduction experiment, where the exhaust {sup 18}F was immediately captured by the [{sup 18}F]FDG synthesizer, showed a very satisfactory 94.3% reduction in the concentration of discharge compared to the existing discharge concentration.

    The Japan Steel Works, Ltd. has been supplying a very small sized cyclotron (Baby Cyclotron) to hospitals and research facilities. The cyclotron is designed to produce short-lived radioisotopes for medical use. In the present study, this cyclotron is modified so that it can serve for PIXE analysis. The PIXE (particle induced X-ray emission) technique has the following features: (1) Down to 1 ng of trace material in a sample (mg - μg) can be detected, (2) An analysis run is completed in one to ten minutes, permitting economical analysis for a large number of samples, (3) Several elements can be analyzed simultaneously, with an almost constant sensitivity for a variety of elements ranging from aluminum to heavy metals, (4) Analysis can be performed nondestructively without a chemical process, and (5) The use of microbeam can provide data on the distribution of elements with a resolution of several μm. Software for analysis is developed to allow the modified equipment to perform peak search, background fitting, and identification and determination of peaks. A study is now being conducted to examine the performance of the equipment for PIXE analysis of thin samples. Satisfactory results have been obtained. The analysis time, excluding the background correction, is 5-10 min. (Nogami, K.)

    This study presents the results of a survey of academic institutions offering nuclear-related training and education at the less than baccalaureate degree level. The scope of the survey includes only those programs which have a nuclear power industry application, and excludes all programs which are affiliated with nuclear medicine. The survey instrument was distributed by the Institute of Nuclear Power Operations to 262 academic institutions. The survey universe was compiled from a number of publications that listed nuclear-related academic programs. Since the initial mailing in May 1981, ten of the institutions have been determined to no longer exist and eight other listings have been identified as duplications, thus reducing the universe to 244 institutions. Fifty-five percent of the survey population (134 institutions) responded to the questionnaire, of which 45 percent (109) were out of the survey scope and 10 percent (25) indicated they offered less than baccalaureate degree, nuclear-related programs

    Full text: One of the main scientific directions of the Institute of Nuclear Physics is the nuclear analytical technique, especially, neutron activation analysis. The main objects of analysis are rocks, ores, water, pure materials and alloys, soil, fertilizers, plants, foods, biological liquids and tissues, etc. There were elaborated and are in use multielemental analytical techniques for these samples. Using cyclotron (accelerated charged particles) the analytical techniques have been elaborated especially for high sensitive determination of oxygen in various materials. Using neutron generator rapid analytical techniques were elaborated for determination of oxygen and other elements. Technique of determination of distribution of hydrogen nuclides is used in study material for thermal nuclear reactors. High sensitive and productive technique of determination of gold and accompanying elements were used in study of geochemistry of gold and gold prospecting. For geology and mining industry the automated system has been created for determination of gold and 10 additional elements with the capacity of 70,000 samples of large grain size of ores and rocks per year. For using of activation analysis in the field or at factories transportable system with nuclide neutron sources ( 252 Cf and 124 Sb-Be) has been constructed. There were also elaborated the techniques of prompt gamma analysis for geology and mining industry. If necessary to increase the sensitivity of determination there were elaborated techniques with radiochemical separation. These methods were used for studying of geochemistry of elements of Pt group, lanthanides, gold and silver. As a result there were elaborated processes of gold and silver extraction from wastes and Re, Sc, Te by production. These results allowed to create joint laboratories at gold producing factory, uranium producing factory, nonferrous metals factory, Ministry of geology, Ministry of internal affairs etc. Studies of human liquids and

    The most used radioisotope in nuclear medicine is 99m Tc, in the 99 Mo- 99m Tc generator form. 99 Mo can be produced by several nuclear reactions in reactors and cyclotrons. The cyclotron production is not technically and economically viable. The production in the reactor can be done in two different ways: by the fission of 235 U and by the 98 Mo(n,γ) 99 Mo reaction. A project for the production of 99 Mo by the activation of Mo and the preparation of gel type generators is under development at the 'Instituto de Pesquisas Energeticas e Nucleares'. In the present work, the radionuclidic impurities produced in the activation of MoO 3 , metallic Mo and Mo Zr gel were evaluated, as well as the radionuclidic purity of 99m Tc eluted from generators prepared.

    Cyclotrons for medical purposes are particularly useful for the production of radioactive isotopes of elements normally constituting organic matter ( 15 O, 13 N, 11 C). The short half-life and positron emission of those elements are of great interest in medical diagnosis. Many others carrier-free radioisotopes can be produced by cyclotrons. Three categories of cyclotrons are mentioned. Desk top cyclotron only adapted to the production of short-lived radioisotopes in a hospital; low energy and average energy cyclotrons which require well-entrained personnel for their operation and are best adapted to the production of radioelements on a regional or even national scale. Examples relative to the interest of short-lived radioisotopes in lung and brain investigations and tumor detection are given

    The PET Cyclotron center (PCC) is a complex for production, research and application of positron radiopharmaceuticals for PET (Positron Emission Tomography), which was commissioned this year (2004) in Bratislava, Slovak Republic. Positron radionuclides are produced by 18/9 MeV proton/deuteron cyclotron CYCLONE 18/9. Radiation protection of personnel and inhabitants against ionizing radiation in the PCC is solved with regard to the ICRP recommendations and Slovak regulatory system, protection rules and criteria and optimization of radiation protection. In the article comparisons of calculated and measured neutron and gamma dose equivalent rates around the CYCLONE 18/9 and at various points behind the shielding of cyclotron vault with maze are presented. Description of the CYCLONE 18/9 as a source of angular distribution of neutron energy spectra (production of 18 F was considered) was simulated by Monte Carlo code MCNPX. Code MCNP4B was used for shielding calculation of cyclotron vault with maze. Neutron energy spectra behind the shielding were measured by Bonner spectrometer. The values of neutron dose equivalent, which were calculated and measured around the CYCLONE 18/9 and at various points behind the shielding of cyclotron vault with maze, are within the range of factor 2.

    On October 01, 2009, the Karlsruhe Institute of Technology (KIT) was founded by a merger of Forschungszentrum Karlsruhe and Universitaet Karlsruhe (TH). KIT bundles the missions of both precursory institutions: a university of the state of Baden- Wuerttemberg with teaching and research tasks and a large-scale research institution of the Helmholtz Association conducting program-oriented provident research on behalf of the Federal Republic of Germany. Within these missions, KIT is operating along the three strategic fields of action, research, teaching, and innovation. With about 8000 employees and an annual budget of about EUR 700 million, KIT is one of the largest research and teaching institutions worldwide. It has the potential to assume a top position worldwide in selected fields of research. The objective: KIT will become an institution of excellent research and scientific education, as well as a prominent location of academic life, life-long learning, comprehensive advanced training, unrestricted exchange of know-how and sustainable innovation culture. The largest organizational units of KIT are the KIT Centers. They focus on problems of fundamental importance to the existence and further development of our society or on key issues of basic science. KIT Centers are characterized by the uniqueness of their scientific approach, their strategic objective and mission and by a long-term perspective. The Institut fuer Nukleare Entsorgung, INE, (Institute for Nuclear Waste Disposal) belongs to the KIT Energy Center. The KIT Energy Center comprises some 40 institutes of the Universitaet Karlsruhe (TH) and 18 large institutes of the Forschungszentrum Karlsruhe with, at present, a total of approx. 1100 staff members. The participating institutes and research groups are the operating research units. An interdisciplinary KIT School of Energy establishes ideal framework conditions for teaching. For external partners from industry, the KIT Center develops solutions in

  9. A mobile superconducting cyclotron for PET and neutron radiography

    Griffiths, R.

    1988-01-01

    The report addresses the development of a mobile superconducting cyclotron for PET (positron emission tomography) and neutron radiography. Proposals for an ultralight cyclotron were made by Finlan et al., who suggested a novel technique of utilising a superconducting magnet with RF acceleration and iron sectors contained within the room temperature bore of the magnet. Detailed design of a cyclotron based on this concept has progressed well at Oxford Instruments. The main design priorities were to minimise the weight and power consumption of the cyclotron. The cyclotron required a large amount of shielding to reduce either radiation background levels or stray magnetic field. Thus low background levels of radiation and magnetic field are key design criteria. The superconducting magnet has a mean field of 2.35 Tesla and a room temperature bore diameter of 500 mm. Three pairs of profiled iron sectors placed in the center of the warm bore of the magnet provide an azimuthally varying magnetic field. This permits the use of high beam currents with low background. A novel technique is incorporated to reduce the stray magnetic field and radiation from the cyclotron. The RF system consists of three pairs of resonators mounted within the warm bore of the magnet between the iron sectors. (Nogami, K.)

    The viewer probe and main probe are used for determining the position and current of charged particles as it is accelerated inside the superconducting cyclotron. The viewer probe is used to visually observe the shape of the charged particle beam inside the cyclotron with the help of a borescope. The main probe measures the distribution of charged particles. The viewer probe and main probe are bellow sealed. They can be positioned with an accuracy of 0.5 mm at different radii within the superconducting cyclotron. M9 slit is placed after the exit flange of the cyclotron. It determines the position of the beam leaving the cyclotron. The beam line has slits, faraday cup, beam viewers, collimators, etc. for beam diagnostics. This paper presents the mechanical design and details of beam diagnostic components. (author)

  11. Cyclotron transitions of bound ions

    Bezchastnov, Victor G.; Pavlov, George G.

    2017-06-01

    A charged particle in a magnetic field possesses discrete energy levels associated with particle rotation around the field lines. The radiative transitions between these levels are the well-known cyclotron transitions. We show that a bound complex of particles with a nonzero net charge displays analogous transitions between the states of confined motion of the entire complex in the field. The latter bound-ion cyclotron transitions are affected by a coupling between the collective and internal motions of the complex and, as a result, differ from the transitions of a "reference" bare ion with the same mass and charge. We analyze the cyclotron transitions for complex ions by including the coupling within a rigorous quantum approach. Particular attention is paid to comparison of the transition energies and oscillator strengths to those of the bare ion. Selection rules based on integrals of collective motion are derived for the bound-ion cyclotron transitions analytically, and the perturbation and coupled-channel approaches are developed to study the transitions quantitatively. Representative examples are considered and discussed for positive and negative atomic and cluster ions.

    If nature created six down quarks for every up quark the world might be a bit more strange. The US population is made up of over 50% women. Hispanic Americans and African Americans make up over 30% of the US population. The processes by which we foster curiosity, educate our youth, encourage people into science, recruit and retain people into physics and welcome them as members of our nuclear physics community results in a much different demographic in the membership of the DNP. Enabling the development of an identity as a scientist or nuclear scientist is a crucial part of mentoring young people to successful careers in nuclear science. Research experiences for students can play a critical role in that identity development. Since 2004, over 170 students have explored nuclear science through the Research Experiences for Undergraduates program Texas A&M University Cyclotron Institute.

    The relational data base of the control parameters of the isochronous cyclotron, Isochronous Cyclotron Data Base (ICDB), is described. The relational data base under consideration, written in Transact SQL for the MS SQL Server 2000 with the use of MS Enterprise Manager and MS Query Analyzer, was installed on the server of the AIC144 isochronous cyclotron in Krakow, which operates under the control of the operating system MS Windows Server 2003 (Standard Edition). The interface of the data base under considerations is written in C++ with the use of Visual C++ .NET and is built in the Cyclotron Operator Help Program (COHP), which is used for modeling the operational modes of the isochronous cyclotron. Communication between the COHP and the relational data base is realised on the base of the Open Data Base Connectivity protocol. The relational data base of the control parameter of the isochronous cyclotron is intended: firstly, for systematization and automatic use of all measured and modelled magnetic field maps in the process of modeling the operational modes; secondly, for systematization and convenient access to the stored operational modes; thirdly, for simplifying the operator's work. The relational data base of the control parameter of the isochronous cyclotron reflects its physical structure and the logic of its operator's work. (author)

    In Greece, there are no nuclear power plants and nuclear energy is not considered as an option in the foreseeable future. There is, however, one nuclear research reactor (in extended shutdown since 2014) and one sub-critical assembly. Radioactive waste originating from medicine, research and industry is classified as low level. Although there is no framework act dealing comprehensively with the different aspects of nuclear energy, there are various laws, decrees and regulations of a more specific nature governing several aspects of nuclear activities. This paper gives information on the general regulatory regime (mining regime, radioactive substances, nuclear fuel and equipment, nuclear installations (licensing and inspection, including nuclear safety, emergency response, trade in nuclear materials and equipment, radiation protection, radioactive waste management, nuclear security, transport, nuclear third party liability) and on the institutional framework with the regulatory and supervisory authorities (Greek Atomic Energy Commission (EEAE))

    The particle accelerators, as the cyclotrons, are extraordinarily important as tools for the radioisotope production and its application in the area of the medicine. In this time, another method exists for the production of artificial radioisotopes, based on the irradiation of samples with alpha particles or with neutrons coming from a natural radioisotope being obtained a neutron source (Ra + Be, Rn + Be, Po + Be). However, its can be obtained a great quantity of radioisotopes by means of cyclotrons in very short time, compared with other methods. After the second world war, artificial radioisotopes took place by means of reactors and its had many applications, not only medical and in little time the accelerators were manufactured that were more indispensable that the reactors to produce radioisotopes with medical aims. For this reason, the accelerators, in few years became in machines very important for the production of artificial radioisotopes and consequently its were developed techniques of radioactive traces progressively more sophisticated, since it is evident that the production of radioactive nuclei through nuclear reactors its cannot satisfy all the demands. In general terms, only the neutrons can be used as nuclear projectiles in reactors and as a result, the production spectra of radioisotopes is limited and as alternative it is unavoidable that the cyclotrons are a good tool for this end. The use of a cyclotron to produce radioisotopes, it can be justified, only if the following conditions are completed. 1. If the radioisotopes of an element produced in a reactor don't favor with the nuclear properties for the purposes of the traced studies, for example: if the half life is very short or very big, if the decay system not to suit him. 2. If the wanted radioisotope cannot produce in the reactor with enough specific activity. (Author)

    The short-lived (12.7 h half-life) {sup 64}Cu radioisotope is both a {beta} {sup +} and a {beta} {sup -} emitter. This property makes {sup 64}Cu a promising candidate for novel medical applications, since it can be used simultaneously for therapeutic application of radiolabelled biomolecules and for diagnosis with PET. Following previous work on {sup 64}Cu production by deuteron irradiation of natural zinc, we report here the production of this radioisotope by deuteron irradiation of enriched {sup 64}Zn. In addition, yields of other radioisotopes such as {sup 61}Cu, {sup 67}Cu, {sup 65}Zn, {sup 69m}Zn, {sup 66}Ga and {sup 67}Ga, which were co-produced in this process, were also measured. The evaporation code ALICE-91 and the transport code SRIM 2003 were used to determine the excitation functions and the stopping power, respectively. All the nuclear reactions yielding the above-mentioned radioisotopes were taken into account in the calculations both for the natural and enriched Zn targets. The experimental and calculated yields were shown to be in reasonable agreement. The work was carried out at the Scanditronix MC-40 Cyclotron of the Institute for Health and Consumer Protection of the Joint Research Centre of the European Commission (Ispra site, Italy). The irradiations were carried out with 19.5 MeV deuterons, the maximum deuteron energy obtainable with the MC-40 cyclotron.

    The status and recent results of experimental nuclear physics in Hungary is reviewed. The basic nuclear sciences, instrumental background and international cooperation are discussed. Personal problems and the effects of the international scientific deconjuncture are described. The applied nuclear and interdisciplinary researches play an important role in Hungarian nuclear physics. Some problems of cooperation of Hungarian nuclear and other research institutes applying or producing nuclear analytical technology are reviewed. The new instrument, the Debrecen cyclotron under construction gives new possibilities to basic and applied researches. A new field of Hungarian nuclear physics is the fusion and plasma research using tokamak equipment, the main topics of which are plasma diagnostics and fusion control systems. Some practical applications of Hungarian nuclear physical results, e.g. establishment of new analytical techniques like PIXE, RBS, PIGE, ESCA, etc. are summarized. (D.Gy.)

    1989-05-01

    Because of an expanding market for radioisotopes there is a need for a new generation of cyclotrons designed specifically for this purpose. TRIUMF is cooperating with a local industrial company in designing and constructing such a cyclotron. It will be a four sector H - cyclotron, exploiting the newly developed high brightness multicusp ion source. This source with H - current capability in excess of 5 mA makes feasible accelerated H - beam intensities of up to 500 μA. Beam extraction is by stripping to H + in a thin graphite foil. Extraction of two high-intensity beams, with energy variable from 15 to 30 MeV is planned. The use of an external ion source, provision of a good vacuum in the acceleration region, and the careful choice of materials for components in the median plane leads to a cyclotron that will have low activation and can be easily serviced in spite of the very high operating beam intensities. A design extension to 70 MeV using many of the design features of the 30 MeV cyclotron can be easily made. Such a machine with a good quality variable energy beam is a highly desirable source of protons for isotope production, injection into higher energy high intensity acceleration, injection into higher energy high intensity accelerators, and as an irradiation facility for ocular melanomas. Design of the 30 MeV cyclotron is well advanced and construction is in progress

    The SCANDITRONIX MC-35 cyclotron laboratory, including the Oslo Cyclotron, has been in operation since 1980. The main auxiliary equipment consists of the multi-detector system CACTUS. During the last years, new, high efficiency Ge(HP) detectors were purchased and integrated in the CACTUS detector array. In connection with that, the electronical setup was revised and altered. Several drawbacks of the old setup could be pointed out and eliminated. A test of the performance of all detector array elements was made with high accuracy. The total beamtime used for experiments in 1998 was 1051 hours. 52 days were used by the Nuclear Physics section, 70 days by the University of Oslo Nuclear Chemistry section and the Norwegian Cancer Hospital used the cyclotron for 12 days. 42 days were spent on maintenance. In experimental nuclear physics, the section members are engaged within three main fields of research: Nuclei at high temperature, high spin nuclear structure and high and intermediate energy nuclear physics

    A study on the heating and diagnosis of tokamak plasma by electromagnetic waves of electron cyclotron range of frequency is summarized. The main results obtained are as follows. On the engineering and technology, the technology of injecting high frequency, large power millimeter waves into tokamak plasma was established by carrying out the design, manufacture and test of a 60 GHz, 400 kW high frequency heating system, and the design, manufacture and test of a heterodyne type electron cyclotron radiation multi-channel mealsuring system were carried out, and the technology of measuring the radiation from tokamak plasma with the time resolution of 10 μs in multi-channel was established. On nuclear fusion reactor core engineering and plasma physics, the high efficiency electron heating of tokamak plasma by the incidence of fundamental irregular and regular waves at electron cyclotron frequency was verified. The discovery and analysis of the heating by electrostatic waves arising due to mode transformation from electromagnetic waves in upper hybrid resonance layer were carried out.

  9. Ponderomotive force near cyclotron resonance

    1987-01-01

    The ponderomotive force, which is involved in the excitation of macroscopic behaviors of plasma caused by wave motion, plays an important role in various non-linear wave motion phenomena. In the present study, equations for the pondermotive force for plasma in a uniform magnetic field is derived using a renormalization theory which is based on the Vlasov equation. It is shown that the pondermotive force, which diverges at the cyclotron resonence point according to adiabatic approximation, can be expressed by a non-divergent equation by taking into account the instability of the cyclotron orbit due to high-order scattering caused by a wave. This is related with chaotic particle behaviors near cyclotron resonance, where the pondermotive force is small and the diffusion process prevails. It is assumed here that the amplitude of the high-frequency electric field is not large and that the broadening of cyclotron levels is smaller than the distance between the levels. A global chaos will be created if the amplitude of the electric field becomes greater to allow the broadening to exceed the distance between the levels. (Nogami, K.).

    The phenomenon of ion cyclotron resonance allows for determining mass-to-charge ratio, m/z, of an ensemble of ions by means of measurements of their cyclotron frequency, ω c . In Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS), the ω c quantity is usually unavailable for direct measurements: the resonant state is located close to the reduced cyclotron frequency (ω + ), whereas the ω c and the corresponding m/z values may be calculated via theoretical derivation from an experimental estimate of the ω + quantity. Here, we describe an experimental observation of a new resonant state, which is located close to the ω c frequency and is established because of azimuthally-dependent trapping electric fields of the recently developed ICR cells with narrow aperture detection electrodes. We show that in mass spectra, peaks close to ω + frequencies can be reduced to negligible levels relative to peaks close to ω c frequencies. Due to reduced errors with which the ω c quantity is obtained, the new resonance provides a means of cyclotron frequency measurements with precision greater than that achieved when ω + frequency peaks are employed. The described phenomenon may be considered for a development into an FT-ICR MS technology with increased mass accuracy for applications in basic research, life, and environmental sciences.

    An 18 GHz superconducting electron cyclotron resonance ion source has been installed as a subject of the azimuthally varying field cyclotron upgrade project (K. Hatanaka et al., in Proceedings of the 17th International Conference on Cyclotrons and Their Applications, Tokyo, Japan, 18-22 October 2004, pp. 115-117), in order to increase beam currents and to extend the variety of ions. The production development of several ions has been performed since 2006 and some of them have already been used for user experiments [T. Yorita et al., Rev. Sci. Instrum. 79, 02A311 (2008)]. Further optimizations for each component such as the material of plasma electrode, material, and shape of bias probe and mirror field have been continued and more intense ion beams have been obtained for O, N, and Ar. For the purpose of obtaining highly charged Xe with several microamperes, the optimization of position and shape of plasma electrode and bias disk has also been done and highly charged Xe(32+) beam has been obtained successfully.

    1997-01-01

    The industrial production of radioisotopes requests cyclotrons with easy maintenance services, high productivity and low operation costs. To obtain this performance the experts on the have achieved excellent results, taking advantage of modern resources in calculation and modeling. Only by the maximum exploitation of the azimutal variation of the magnetic field, a physical concept introduced in 1967 with the isocronous cyclotrons, it was possible to construct cyclotrons with only 30% of the electrical consumption required by the former cyclotrons. On the other hand, the acceleration of negative ions enable the 100% accelerated beam utilization, without internal energy dissipation, obtaining beam intensities up to 1mA in continuous running which represents an increased factor of 15. Other construction parameters were optimized aiming at reliability and reduction in the components activation. Concerning energy consumption and the beam intensity supplied, a present cyclotron with 30 MeV and 300μA of protons current is 15 times more efficient than its precedent.

    ACSI is designing a new 30 MeV cyclotron based on the TR-24. While minimizing changes from the proven TR-24, including maintaining the same outer dimensions, the energy of the cyclotron will be increased to 30 MeV, which will make it the most compact, non-superconducting, 30 MeV cyclotron design to date. Maximum beam current will match the TR-24 at 1 mA. With the size and footprint of a typical low energy PET cyclotron, this system will offer users a cost effective solution for a diversified facility capable of producing a wide spectrum of PET and SPECT radioisotopes for research and commercial distribution.

    1990-01-01

    Since a small cyclotron and a positron emission tomography (PET) scanner have been installed at the Kyoto University Hospital in 1983, a great deal of effort has been directed to the clinical application of the PET-cyclotron system. This paper outlines the experience with PET in the clinical setting, including the facility, equipments and staff involved, weekly schedule, typical clinical protocols, and some results from the patients. The system consists of small cyclotron for production of the short-lived positron emitting radionuclides, fully automated synthesis system for labeling various compounds, scanning for measurement of radioactivities, and data analysis system for calculating physiological parameters. A resolving cylinder target system with eight smaller cylinders is equipped for production of C-11, N-13, O-15, and F-18. Labeled compounds are quickly delivered to the PET scanner room by two systems--the continuous delivery system for the labeled gas and the rapid delivery system for the liquid compounds by compressed air. A PET scanner devoted for clinical studies is a multislice whole-body PET scanner. Ten PET studies are performed weekly on the average for measuring blood flow and oxygen and glucose metabolism in the brain, blood flow and glucose and fatty acid metabolism in the heart, blood flow and amino acid uptake in the pancreas, lung ventilation, and tumor glucose metabolism. The availability of PET-cyclotron system is still limited in view of cost. The previous clinical studies suggest the contribution of PET to the the understanding of the mechanism of disease pathophysiology. (N.K.)

  2. Fundamental harmonic electron cyclotron emission for hot, loss-cone type distributions

    Bornatici, M.; Ruffina, U.; Westerhof, E.

    1988-01-01

    Electron cyclotron emission (ECE) is an important diagnostic tool for the study of hot plasmas. ECE can be used not only to measure the electron temperature but also to obtain information about non-thermal characteristics of the electron distribution function. One such a nonthermal characteristic is a loss-cone anisotropy. Loss-cone anisotropy can give rise to unstable growth of electro-magnetic waves around the harmonics of the electron cyclotron resonance and to increased emissivity of electron cyclotron waves. In case of high electron temperatures, also the dispersion properties of the extraordinary (X-) mode arond the fundamental electron cyclotron resonance are changed due to loss-cone anisotropy. The consequences of these dispersion properties for the emissivity of the fundamental harmonic X-mode are analyzed for perpendicular propagation. The emissivity, is calculated for two types of distribution functions having a loss-cone anisotropy. These distribution functions are a relativistic Dory-Guest-Harris type distribution function and modified relativistic Maxwellian distribution having a loss-cone with rounded edges (author). 9 refs.; 2 figs

    The CYCIAE230 is a low-current, compact superconducting cyclotron designed for proton therapy. The Radio Frequency system consists of four RF cavities and applies second harmonic to accelerate beams. The driving power for the cavity system is estimated to be approximately 150 kW. The LLRF controller is a self-made device developed and tested at low power using a small-scale cavity model. In this paper, the resonator systems of an S.C. cyclotron in history are reviewed. Contrary to those RF systems, the cavities of the CYCIAE230 cyclotron connect two opposite dees. Two high-power RF windows are included in the system. Each window carries approximately 75 kW RF power from the driver to the cavities. Thus, the RF system for the CY-CIAE230 cyclotron is operated in driven push–pull mode. The two-way amplifier-coupler-cavity systems are operated with approximately the same amount of RF power but 180° out of phase compared with each other. The design, as well as the technical advantage and limitations of this operating mode, of the CYCIAE230 cyclotron RF system is analyzed.

    1989-10-01

    It is proposed by a large community of PSI- and external scientists to install an electron cyclotron resonance (ECR) source for highly charged heavy ions at the PHILIPS (injector I) cyclotron. Such a facility would then allow to produce high intensity ion beams with energies up to 30 MeV/u. A workshop hold in June 1989 clearly showed that with such a machine a large variety of interesting heavy ion experiments could be performed. While at foreign heavy ion centres the main focus is given to basic research in the field of nuclear physics we propose to concentrate the scientific effort at a PSI heavy ion facility mainly onto applications in the fields of atomic physics, chemistry, accelerator mass spectrometry, radiation biology and solid state physics. This is adequate, in view of the broad infrastructure available at PSI together with the existing know-how in many different fields. The proposed machine will thus be of great potential use for a large community. (author) 19 figs., 3 tabs., 82 refs

    Absorption of fast Alfven waves by the energetic ions of an injected beam is evaluated in the DIII-D tokamak. Ion cyclotron resonance absorption at the fourth harmonic of the deuteron cyclotron frequency is observed with deuterium neutral beam injection (f=60 MHz, B T =1.9 T). Enhanced D-D neutron rates are evidence of absorption at the Doppler-shifted cyclotron resonance. Characteristics of global energy confinement provide further proof of substantial beam acceleration by the rf. In many cases, the accelerated deuterons cause temporary stabilization of the sawtooth (''monster sawteeth''), at relatively low rf power levels of ∼1 MW. (c) 1999 American Institute of Physics

    According to the National Nuclear Energy Commission (CNEN) resolution 112/2011, administrative controls must be applied during the construction of a cyclotron and documents must be created showing that the facility can operate without radiological risks, referring even to the shielding efficiency. This study aimed to perform the analysis of the construction and efficiency of the bunker built for shielding, in the cyclotron of University of Sao Paulo Medical School Health System. This was possible through the measurements of a radiometric survey in normal working conditions, and testing related to compression resistance and density. The results showed that the compression resistance of the concrete used is higher than the expected value and the average density value obtained is within the tolerated limits. The radiometric survey results showed that the levels of ionizing radiation are well below the established limits. (author)

    Chu, T.C.

    1980-01-01

    A multi-energy group technique is developed to study conditions under which cyclotron radiation emission can shift a Maxwellian electron distribution into a non-Maxwellian; and if the electron distribution is non-Maxwellian, to study the rate of cyclotron radiation emission as compared to that emitted by a Maxwellian having the same mean electron density and energy. The assumptions in this study are: the electrons should be in an isotropic medium and the magnetic field should be uniform. The multi-group technique is coupled into a multi-group Fokker-Planck computer code to study electron behavior under the influence of cyclotron radiation emission in a self-consistent fashion. Several non-Maxwellian distributions were simulated to compare their cyclotron emissions with the corresponding energy and number density equivalent Maxwellian distribtions

    2001-01-01

    The Nuclear Energy Institute (NEI) provided a brief presentation on the state of energy demand in the United States and discussed the improving economics for new nuclear power plants. He discussed the consolidation of companies under deregulation and the ability of these larger companies to undertake large capital projects such as nuclear power plant construction. He discussed efforts under way to support a new generation of plants but noted that there needs to be greater certainty in the licensing process. He discussed infrastructure challenges in terms of people, hardware, and services to support new and current plants. He stated that there needs to be fair and equitable licensing fees and decommissioning funding assurance for innovative modular designs such as the PBMR. He concluded that NRC challenges will include resolving 10 CFR Part 52 implementation issues, establishing an efficient and predictable process for siting, COL permits and inspection, and an increasing regulatory workload

    Radiolanthanide praseodymium-142 (T 1/2 = 19.12 h, E β - = 2.162 MeV (96.3%), E γ = 1575 keV (3.7%)) due to its high β-emission and low specific γ-emission could not only be a therapeutic radionuclide, but also a suitable radionuclide in order for biodistribution studies. Conventionally, 142 Pr produces via 141 Pr(n,γ) 142 Pr reaction by irradiation in a low-fluence reactor and this study evaluates cyclotron reaction production of it. 142 Pr excitation function via nat La(α,n) 142 Pr, 142 Ce(p,n) 142 Pr, and nat Pr(d,p) 142 Pr reactions were calculated by TALYS-1.2 and EMPIRE-2.19beta codes, and with the data taken from the TENDL-2010 database. In addition, we compared them with the reported measurement by experimental data. Requisite thickness of targets was obtained by SRIM-2010 code for each reaction. The 142 Pr production yield was evaluated with attention to excitation function and stopping power. Similar to reactor produced 142 Pr; 141 Pr impurity exists in cyclotron produced 142 Pr while it could not be separated by chemical methods. Therefore, cyclotron and reactor produced 142 Pr will be in carrier added form. (author)

    Full text: In 2002, the Department has been involved in two new experimental programmes. Our colleagues led by Prof. Pawel Zupranski joined a large international collaboration HERMES and took part in experiments at DESY devoted to the study of the spin structure of the nucleon. Another group directed by Associate Prof. Bogdan Zwieglinski has worked on a conceptual design of a new generation detector PANDA (Proton-Antiproton Detection) which will be used in future experiments at GSI. Moreover, the experimental programmes covering three major domains of our scientific activities: nuclear physics, materials research and atomic physics were continued. - Nuclear physics: Experimental studies of nuclear reactions induced by heavy ions provided by the Warsaw U-200P Cyclotron were performed in collaboration with scientists from the Institute for Nuclear Studies in Kiev, Ukraine. The aim of the experiments was to investigate isotopic effects in the scattering of 11 B from carbon nuclides. Also, excited states of 6 Li predicted theoretically but never seen in experiments were investigated by means of one-neutron transfer reactions. Proton induced reactions were investigated theoretically by means of the multistep-direct model. Good agreement with the experimental data was achieved. The mechanism of fragments production in collisions of 197 Au with a gold target in the wide range of energies was studied by ALADIN and INDRA Collaborations. The production of η mesons from proton - proton collisions was investigated experimentally at the Juelich Cooler Synchrotron COSY. - Atomic physics: The ionisation of Au, Bi, Th and U atoms by Si ions was investigated in collaboration with the Swietokrzyska Academy, Kielce, and the University of Erlangen-Nuernberg. - Materials research: The sensitivity of the Solid State Nuclear Track PM-355 detectors was tested against intensive gamma and electron radiation. Moreover, using a monoenergetic sulphur ion beam from the Warsaw Cyclotron, the

  1. Emittance Measurement for Beamline Extension at the PET Cyclotron

    2016-01-01

    Full Text Available Particle-induced X-ray emission is used for determining the elemental composition of materials. This method uses low-energy protons (of several MeV, which can be obtained from high-energy (of tens MeV accelerators. Instead of manufacturing an accelerator for generating the MeV protons, the use of a PET cyclotron has been suggested for designing the beamline for multipurpose applications, especially for the PIXE experiment, which has a dedicated high-energy (of tens MeV accelerator. The beam properties of the cyclotron were determined at this experimental facility by using an external beamline before transferring the ion beam to the experimental chamber. We measured the beam profile and calculated the emittance using the pepper-pot method. The beam profile was measured as the beam current using a wire scanner, and the emittance was measured as the beam distribution at the beam dump using a radiochromic film. We analyzed the measurement results and are planning to use the results obtained in the simulations of external beamline and aligned beamline components. We will consider energy degradation after computing the beamline simulation. The experimental study focused on measuring the emittance from the cyclotron, and the results of this study are presented in this paper.

    2001-01-01

    This article (Chapter One) discusses the two main scenarios typically advanced for Canada's nuclear energy future. The first view is that the nuclear energy industry can prosper and make an important contribution to energy and the environment in this age of climate change policy. This view is supported by some recent international studies which also express cautious optimism. A somewhat different view is the perception by some that the nuclear industry is economically in decline and environmentally questionable. These views have emerged as a result of recent serious safety concerns that have been raised about British nuclear Fuels Ltd (BNFL) regarding MOX fuel, where it has been alleged that data on safety were faked by BNFL workers. This article also provides an overview of how nuclear policy ideas, policy institutions, and policy interests have changed. Second, it draws out in more detail key policy and institutional choices confronting Canada's nuclear policy makers

    A computer-based operation system for a cyclotron which assists inexperienced operators has been developed. Cyclotron start-up operations require dozens of adjustable parameters to be finely tuned to maximize extracted beam current. The human interfaces of the system provide a visual environment designed to enhance beam parameter adjustments. First, the mental model of operators is analyzed. It is supposed to be composed of five partial mental models: beam behavior model, feasible setting regions model, parameter sensitivity model, parameter mutual relation model, and status map model. Next, based on these models, three visual interfaces are developed, i.e., (1) Beam trajectory is rapidly calculated and graphically displayed whenever the operators change the cyclotron parameters. (2) Feasible setting regions (FSR) of the parameters that satisfy the cyclotron's beam acceptance criteria are indicated. (3) Search traces, being a historical visual map of beam current values, are superimposed on the FSRs. Finally, to evaluate system effectiveness, the search time required to reach maximum beam current conditions was measured. In addition, system operability was evaluated using written questionnaires. Results of the experiment showed that the search time to reach specific beam conditions was reduced by approximately 65% using these interfaces. The written questionnaires survey showed the operators highly evaluate system operability. (author)

    1948-12-01

    This work is a detailed study of the operating conditions of the cyclotron. It analyzes the behaviour of the particles from their first accelerations to their arrival on an external target. Calculations were performed using relativistic formulations in order to make the results usable without any energy level restriction. The obtained results supply some numerical elements for a cyclotron pre-determination and allow a satisfactory visualization of the real phenomena taking place during the accelerations. The shape of the phase change during the successive accelerations has been obtained for a given magnetic field configuration with respect to the operating frequency, to the magnetic field value in the center, and to the accelerating voltage between the dees. Taking into account the limitations due to the accelerating and focussing conditions, the usable phase interval has been determined with respect to the characteristic operating parameters. The study of this phase interval with respect to the accelerating voltage, on the one hand, and with respect to the frequency or to the center magnetic field, on the other hand, has permitted to find again two facts experimentally observed: voltage threshold and dissymmetry of the response curve. The study of radial and axial oscillations has shown the existence of precession phenomena and indicates a maximum limit for the magnetic field variation in order to avoid the disturbances due to oscillations coupling. The study of the ion beam envelope inside the chamber with respect to the initial phases has permitted to determine the optimum shape of the dees and the height of the deflecting channel. Moreover, the influence of various parameters on the ion beam efficiency can be shown using an ideal source. The study of the passing conditions inside the deflecting channel has shown the influence of the separation sheet, has given the dimensions to foresee for the deflecting channel, and has indicated the way to follow to obtain

    1993-01-01

    Continuing increases in requirements from the nuclear medicine industry for cyclotron isotopes is increasing the demands being put on an aging stock of machines. In addition, with the 1990 recommendations of the ICRP publication in place, strict dose limits will be required and this will have an effect on the way these machines are being operated. Recent advances in cyclotron design combined with lessons learned from two decades of commercial production mean that new facilities can result in a substantial charge on target, low personnel dose, and minimal residual activation. An optimal facility would utilize a well engineered variable energy/high current H - cyclotron design, multiple beam extraction, and individual target caves. Materials would be selected to minimize activation and absorb neutrons. Equipment would be designed to minimize maintenance activities performed in high radiation fields. (orig.)

  16. Passive cyclotron current drive for fusion plasmas

    Kernbichler, W.

    1995-01-01

    The creation of toroidal current using cyclotron radiation in a passive way is, together with the well known bootstrap current, an interesting method for stationary current drive in high-temperature fusion reactors. Here, instead of externally applied RF-waves, fish-scale like structures at the first wall help to create enough asymmetry in the self generated cyclotron radiation intensity to drive a current within the plasma. The problem of computing passive cyclotron current drive consists of actually two linked problems, which are the computation of the electron equilibrium under the presence of self-generated radiation, and the computation of the photon equilibrium in a bounded system with a distorted electron distribution. This system of integro-differential equations cannot be solved directly in an efficient way. Therefore a linearization procedure was developed to decouple both sets of equations, finally linked through a generalized local current drive efficiency. The problem of the exact accounting for the wall profile effects was reduced to the solution of a Fredholm-type integral equation of the 2 nd -kind. Based on all this an extensive computer code was developed to compute the passively driven current as well as radiation losses, radiation transport and overall efficiencies. The results therefrom give an interesting and very detailed insight into the problems related to passive cyclotron current drive
