  Michael K. Craddock, TRIUMF accelerator physicist and UBC professor, died on 11 November, 2015 after a brief illness. Michael left the UK to join the UBC Nuclear Physics group in 1966, just at the time a new accelerator to replace the aging Van de Graaff was under consideration. He was a leading member of the founding team that decided on a 500 MeV H¯ cyclotron and directed the beam dynamics design of the cyclotron to first beam in December 1974. With the cyclotron running at full intensity he moved his interest to higher energies and led the accelerator physics team in the design of the 30 GeV KAON Factory (1982-1994). After retirement from UBC in 2001 he moved his research interest to FFAGs.

  At high power accelerators, radiation damage becomes an issue particularly for components which are hit directly by the beam, like targets and collimators. Protons and secondary particles change the microscopic (lattice) structure of the materials, which macroscopically affects physical and mechanical properties. Examples are the decrease of thermal conductivity and ductility as well as dimensional changes. However, the prediction of these damage effects and their evolution in this harsh environment is highly complex as they strongly depend on parameters such as the irradiation temperature of the material, and the energy and type of particle inducing the damage. The so-called term "displacements per atom" (DPA) is an attempt to quantify the amount of radiation induced damage and to compare the micro- and macroscopic effects of radiation damage caused by different particles at different energies. In this talk, the basics for understanding of the mechanisms of radiation damage will be explained. The definition and determination of DPA and its limitations will be discussed. Measurements and examples of the impact of radiation damage on accelerator components will be presented.

  Huazhong University of Science and Technology (HUST) has planned to build a proton therapy facility based on an isochronous superconducting cyclotron. The 250 MeV/500 nA proton beam is extracted from a super-conducting cyclotron. To modulate beam energy, an en-ergy selection system is essential in the beam-line. The simulation based on Geant4 has been performed for the energy selection system and its result will be discussed in this paper. This paper introduces the variation rules of the beam parameters including the beam energy, beam emit-tance, energy spread and transmission. The degrader's gap and the twiss parameter are proven to be effective ways to reduce the emittance after degrader.

For implementation of proton therapy, Huazhong University of Science and Technology has planned to construct a 250 MeV/500 nA superconducting cyclotron for proton therapy. In the beam-line, the scanning system spreads out the proton beam on the target according to the complex tumor shape by two magnets for horizontal and vertical scanning independently. As dipole magnets are excited by alternating currents and the maximum repetition rate is up to 100 Hz, the eddy currents are expected to be large. This paper introduces the design of these two scanning magnets and analyzes the eddy current effect. Slits in the end pole are proven to be an effective way to reduce the eddy current. Different directions, distributions and width sizes of slits are simulated and compared to determine the slits arrangement. At last, the maximum temperature of the optimized scanning magnets reaches the temperature requirements.

  The SPES (Selective Production of Exotic Species) facility purposes are the production of radioactive beams (RIBs) by ISOL technique, the production and the research on innovative radioisotopes and experiments with high intensity neutron beams. For these reasons the 70p cyclotron, designed by BEST Cyclotron Systems Ins., has been installed at Laboratori Nazionali di Legnaro: it is a machine able to produce a beam current up to 700 μA shared into two extraction channels. Beams at the energy values of 35 MeV, 50 MeV and 70 MeV have to be transported to the experimental areas with specific properties and minimizing the beam losses. Here, the main features of the needed beamlines are described.

  Two electrostatic deflectors are used for beam extraction of the 230 MeV superconducting cyclotron CYCIAE-230, which is under development at CIAE. Resonance crossing and processional motion are introduced by a first harmonic bump of main field during the beam dynamics design to increase the turn separation and accordingly the extraction efficiency. Four trim-rods of variable depth are employed to generate the desirable field bump for their stability, the amplitude and azimuth of first harmonic bump can be adjusted with different size and depth of trim-rods. However, effect on isochronous field in acceleration region is followed by trim-rods in practice, therefore the base depth of trim-rods need to be designed and re-shimming procedure of main magnet model need to be implemented interactively. The effect of trim-rods and isochronous field production by a new model will be presented in this paper.

An 11-MeV proton-accelerating cyclotron has been employed to produce F-18 and Tc-99m radionuclides. In this report, F-18 radionuclide was produced from enriched-water target whereas Tc-99m was generated from natural molybdenum trioxide (MoO3) target. Two recoiled radioactive impurities such as Co-56 and Ag-110m are identified in the F-18 solution whereas N-13 was recognized as an impurity in the Tc-99m production. The Co-56 radionuclidic impurity is presumably sputtered off the havar window in the target system whereas Ag-110m is originally from a silver body housing the enriched water target which is generated by secondary neutron irradiated Ag-109. In addition, N-13 impurity found in the post-irradiated MoO3 target occurs presumably via (p,He-4) nuclear reaction.

  ISOLPHARM is a branch of the INFN-LNL SPES project*, aimed at the production of radioisotopes for medical applications according to the ISOL technique. Such an innovative method will allow to obtain radiopharmaceuticals with very high specific activity. In this context a primary proton beam, extracted from a cyclotron will directly impinge a target, where the produced isotopes are extracted and accelerated, and finally, after mass separation, only the desired nuclei are deposed on a secondary target. This work is focused in the design and study of the aforementioned production targets for a selected set of isotopes, in particular for 64Cu, 89Sr, 90Y, 125I and 131I. 64Cu will be produced impinging Ni targets, otherwise the SPES UCx target is planned to be used. Different target configurations are being studied by means of the Monte Carlo based code FLUKA for the isotope production calculation and the Finite Element Method based software ANSYS ® for the temperature level evaluation. An appropriate secondary target substrate for implanting the produced isotopes is under study alongside with a system for its dissolution and repartition into radiopharmaceutical doses.

  At the Forschungszentrum Jülich (FZJ) the intermediate energy cyclotron JULIC, used as injector of the Cooler Synchrotron (COSY) and COSY itself, have been enabled to perform low to medium current irradiations. Main task is to support the FZJ radionuclide research programme of INM-5. Target holders of the INM-5 were implemented to the external target station of JULIC to obtain reliable irradiations with 45 MeV protons and 76 MeV deuterons for nuclear reaction cross section measurements and medical radionuclide production. For testing of radiation effects, displacement damage DD and single event effects SEE, with energetic protons for electronics used in space and accelerators the beam can be extracted to a dedicated test stand, e.g. used by Fraunhofer INT. To provide these possibilities up to 2.5 GeV as well one external beamline of the cooler synchrotron COSY will be equipped with a new irradiation station and adaption for the dosimetry systems are done. Different dosimetry systems (PTW Farmer® chambers, Bragg Peak chambers, Gafchromic® dosimetry films) are available to monitor and control the ongoing irradiation. This report briefly summarizes the relevant technical activities.

  The fast timing capabilities, compactness, high sensitivity and radiation hardness of diamond detectors make them ideally suited for measurements in the pulsed beam from the S2C2. In this communicaiton, we will present first results obtained on the S2C2 with such a diamond probe and the mechanical design of a dedicated test bench to be used for factory tests. The test bench is able to measure the beam direction, the intensity distribution in the beam, the emittance (with an emittance slit) and the exact moment when the beam is extracted from the S2C2. We are able to measure the frequency at which the protons are extracted from the S2C2 and to observe small (<100 keV) mean energy fluctuations in the extracted beam. All these measurements can be done with extreme low beam intensities so that activation of the S2C2 is highly reduced.

The application of radioisotopes in medical radiology is essential for diagnosis and treatment of cancer. The fabrication of radioisotopes has main factors that maximize the fabrication yield and minimize the costs. An effective method to solve this problem is that the usage of Monte Carlo simulations before experimental procedure [1]. This paper studies the simulation and presents cyclotron models for the energy 13 MeV with moderate beam intensity are used for production of 11C, 13N, 15O, and 18F isotopes widely applied in positron emission tomography [1]. SKKUCY-13 cyclotrons with high beam intensity are available on the market for production of most medical and industrial isotopes. In this work, the physical and technical parameters of different models are compared. Overall, this confirms the applicability of Monte-Carlo to simulate radionuclide production at 13 MeV proton beam energy.

  RFT-30 30 MeV cyclotron has been developed for the production of radioisotopes and their applications. Fluorine-18, which is a widely-used positron emitter, has been produced regularly since 2015. In addition, research on the production of generator radioisotopes has been performed using this cyclotron. A generator means a device used to extract the positron-emitting daughter radioisotope from a source of the decaying parent radioisotope such as Ti-44 and Ge-68. In this research, gold-coated and natural Sc targets were proton-irradiated in order to produce Ti-44. Gamma spectra of irradiated targets were measured to confirm the production of Ti-44.

  Cyclotron and Linac technologies cover the vast majority of accelerator solutions applied to medicine. Cyclotrons with beams of H+/H− around 20 MeV are found for radioisotope production and cyclotrons with beams up to 250 MeV are widely used for protontherapy. Linacs are present in every medium-sized hospital with electron beams up to 20 MeV for radiotherapy and radioimaging. They have also recently become available as commercial products for protontherapy. The coupling of these two strong technologies enables to expand the capabilities of cyclotrons by using linacs as boosters. This opens the way to innovative accelerator systems allowing both radioisotope production and ion beam therapy (cyclinacs), new treatment techniques (high energy proton therapy) and new imaging techniques (proton radiography). This paper provides an overview of the technical challenges linked to coupling cyclotrons to linacs and the various solutions at hand.

  In cooperation with the university hospital Charité – Universitätsmedizin Berlin the Helmholtz-Zentrum Berlin (HZB) provides a proton beam used for radiation therapy of intraocular tumors. The protons are accelerated to 68 MeV by an isochronous cyclotron as the main accelerator. The human eye is a very small and complex organ with several critical structures which must be spared from irradiation as much as possible. Hence radiation therapy with protons is especially convenient due to their well-defined Bragg peak. At the HZB the distal fall off (the distance between 90% and 10% of the dose level) is less than 1 mm in water. Therefore it is crucial to measure the energy and maximum range of the beam with the corresponding high accuracy. A Multi-Leaf Faraday Cup (MLFC) allows a quick and precise range-measurement of proton beams. We present a MLFC which meets those special requirements of the eye tumor therapy. Results of range-measurements in different energy regions revealing the achievable submillimeter precession are shown; and examples for applications in radiation hardness testing are given.

The COMET cyclotron* at PSI has been successfully used to treat patients with static tumors using the spot scanning technique, i.e. sequentially irradiating different positions inside the tumor volume. Irradiation time for each position ranges from micro- to milliseconds, with total treatment duration of about a minute. For some tumors (e.g. lung) physiological motion (e.g. respiration) interferes with the scanning motion of the beam, lowering treatment quality**. For such mobile tumors, we are developing a new technique called continuous line scanning (CLS), aiming at reducing treatment time by more than 50%. In CLS, dose rate should stabilize (within few percent) within tenths of a millisecond. We thus implemented a first prototype for fast, real-time beam control: a PID controller sets the internal electrostatic vertical deflector of the accelerator, regulating the beam current output based on the instantaneous current measured just before the patient and the knowledge of the transmission from the accelerator to the patient. In pre-clinical experiments, we achieved good control of the global dose delivered; open issues will be tackled in the next version of the controller.

  While most of the beam time of the cyclotron is used for proton therapy of ocular melanomas, an increasing amount of beam time is used for experiments. In response to a growing demand on time structures a new pulse suppressor was developed. This was necessary as our cyclotron was originally designed for heavy ions, thus limiting us to repetition rates of 75 kHz for light ions. The pulse suppression is now accomplished completely on the low-energy side, making the pulse suppressor on the high energy side, which was needed for single pulses, superfluous. With this new pulse suppressor the repetition rate of the pulse may be varied from 2 MHz down to 1 Hz or less. The pulse length can be freely chosen from a quasi-continuous beam to single pulses with a pulse width less than 1 ns. The pulses are measured either with a specially developed Faraday cup or non-destructively with a pick-up. The extraction of single pulses surveys very precisely if single turn extraction is achieved. The set-up of the pulse suppressor, measurements on the time structures for various beams and examples of their experimental use will be presented.

TUC01 100 MeV H− Cyclotron Development and 800 MeV Proton Cyclotron Proposal cyclotron, ion, target, ion-source 149
 
  • T.J. Zhang, J.J. Yang

  Since the last cyclotron conference in Vancouver, significant milestones have been achieved on the BRIF (Beijing Radioactive-Ion Beam Facility) project. On July 4, 2014 the first 100MeV proton beam was extracted from the H− compact cyclotron. The cyclotron passed beam stability test with beam current of 25 μA for about 9 hours operation. In the year of 2015, the first radioactive ion beam of K-38 was produced by the ISOL system, and the beam current on the internal target of the 100 MeV cyclotron was increased to 720 μA. In the year of 2016, the cyclotron was scheduled to provide 1000 hours beam time for proton irradiation experiment, single-particle effects study and proof-of-principle trial on the proton radiography technology. It is also planed to build a specific beam line for proton therapy demonstration on the 100 MeV machine. In this talk, I will also introduce our new proposal of an 800 MeV, room temperature separate-sector proton cyclotron, which is proposed to provide 3~4 MW proton beam for versatile applications, such as neutron and neutrino physics, proton radiography and nuclear waste treatment.

  An innovative isochronous cyclotron for PET radioisotope production has been designed, constructed, tested and industrialized at Ion Beam Applications (IBA) [1]. This cyclotron (patent application pending) produces 18MeV proton beam and is called the Cyclone® KIUBE. The design has been optimized for cost-effectiveness, compactness, ease of maintenance and high performance, which are key elements considering its application in the dedicated market. Compared to the previous 18 MeV protons and 9 MeV deuteron machine from IBA, Cyclone® 18/9, the gap between the poles has been reduced from 30 to 24 mm and the method of shimming to obtain isochronous magnetic field has been reviewed thoroughly. In early 2016, the prototype Cyclone® KIUBE was successfully commissioned at the IBA factory and the observed proton beam intensity outperformed Cyclone® 18/9.

  In October 2013, IBA sold its first Cyclone®70p, ex-tracted 70 MeV proton machine to Zevacor Pharma, Indianapolis, IN, USA. This brand new machine combine the advantages of the design of the Cyclone®30 HC (1,5mA extracted beam) and the Cyclone®70 XP (multi-particle). Moreover, this high energy cyclotron has been optimized for H− ions acceleration, activation reduction and long term beam production. The installation will be used for high power and long term irradiations of rubidium Rb targets to produce stron-tium 82Sr generator applied in the field of cardiac imaging. From cyclotron to beam lines and up to the target sta-tion, all subsystems have been reviewed to reach highest level of quality, reduce the activation (by the use of low activation material and reduction of beam losses) and finally optimized the maintenance. For that delivery, the machine will be equipped with 6 beam transport lines and 2 solid target station units. In June 2015, about 21 months after contract signature, the IBA Factory Acceptance Tests have been successfully performed in Belgium and the machine was shipped to Indianapolis, IN, USA to be installed in Customer factory cyclotron vault.

  The IBA CYCLONE®70p is a high intensity 70 MeV proton-only cyclotron dedicated to the production of radioisotopes for PET generators and SPECT. The nominal power of the extracted beam goes above 50kW (750μA@70MeV). The proton-only cyclotron was developed based on the previous experience of the multi-particle Cyclone® 70XP running in Nantes, France. Numerical tools have been extensively used to optimize the magnetic field, to avoid potentially harmful resonances during acceleration and improve the acceleration efficiency of the cyclotron. In addition, electromagnetic and mechanical calculations permitted to obtain a low dissipated power and electromechanically robust design of the RF system. The vacuum computations have permitted to optimize the beam transmission, the placement and type of cryopumps. This new development of CYCLONE®70p was the initial part of the successfully finished IBA project also presented during this conference [1].

  The SPES facility is entered the commissioning phase and the 70 MeV cyclotron is delivering the proton beams at the maximum power permitted. The INFN team has developed additional beam instrumentation in order to stop the particles at different power allowing the tuning of the beamline and to check the particles losses during the transport. In particular, a beam dumper able to stop up to 55kW beam power has been constructed and tested as well as the beam loss monitor system by INFN team. Here we present the status of the beam instrumentations supplied by INFN and the results achieved during the test with the beam.

This work discusses a method to measure the protons energy from the CS 30 Cyclotron at KFSHRC. Using two Fast Current Transformers (FCT), particles' Time of Flight (ToF) can be accurately determined by using windowed cross-correlation method. Existing techniques use pulse width or edge delay measurement to get the ToF. The accuracy of these methods, however, is limited by sampling rate, signal level, noise, and distortion. By using Cross-Correlation and interpolation, on the other hand, a fractional delay measurement can be obtained, and the system works with low level signals, i.e. high S/N ratio. During experiments, time delay measured between the two signals was 9.4023 ns. By using relativistic equations cyclotron energy was calculated and found to be 25.99 MeV, bearing in mind that cyclotron energy (mentioned in the CS30 manual) is 26.5 MeV for protons. The difference between actual and calculated energy was <2%. Results will be further discussed and analyzed.

  A 100 MeV H− compact cyclotron is under construction at China Institute of Atomic Energy (CYCIAE-100). The proton beams ranging from 75 MeV - 100 MeV with 200 μA beam intensity will be extracted in dual opposite direction by charge exchange stripping devices. The stripping probe system is the key part of extraction system for CYCIAE-100. The first stripping extraction system was installed in 2014 and it has satisfied all kinds of requirements for the proton beam extraction. The first 100 MeV proton beam was got on July 4, 2014 and the beam current was stably maintained at above 25 μA for about 9 hours on July 25, 2014. The first RIB with ISOL system driven by 100 MeV proton beam was generated in 2015. The second stripping system was installed in 2015 after the assembly and adjustment. The beam commissioning based on the second stripping system will be finished and the extracted proton beam parameters will be measured in detail in this year.

  After the first beam on July 4 2014, CYCIAE-100's performance have been improved gradually and is ready for routine operation. There are 7 beam lines in total in the design stage, i.e. N1:ISOL, N2:isotope production, N3:beam dump, S1: single energy neutron, S2:white light neutron source, S3: radiobiological effect, S4:single event effect. The beam lines N2 and N3 were combined into one line during the construction. In the last two years, we propose to build to two new lines, one for principle verification of Proton Radiography, the other one for demonstration of proton therapy. Both of them are quite special. In this paper, a control system for the operation of the beam line of proton radiography, including the magnets, vacuum and water cooling, the beam intensity & profile diagnostics, and the imaging etc, will be presented.

  The SC200 is a compact superconducting cyclotron, which is designed under the collaboration of ASIPP (Hefei, China)-JINR (Dubna, Russia), for proton therapy. The protons are accelerated to 200 Mev with maximum beam current of 500 nA. The very high mean magnetic field of 2.9T-3.5T (center-extraction) challenges the design of radio frequency (RF) system because of the restricted space. The orbital frequency of the protons is ~45 MHz according to the magnetic field and beam dynamics. The RF system is supposed to operate on 2rd harmonic of ~90 MHz. Two Dee cavities located at the valley of the magnet have been adopted. The preliminary design of RF system, which consists of active tuning, coupling and so on, is presented. The computation and simulation showed good results to ensure the Dee cavities operating at the 2rd harmonic and the proper variation of acceleration voltage versus radius.

  To produce a radio isotope for Positron Emission To-mography (PET), 10 MeV compact Cyclotron was in-stalled at Sungkyunkwan University. This cyclotron had been produced 10 MeV proton beam. For this cyclotron magnet, the magnetic field measurement instrumentation was being developed. The hall probe sensor was used for field measurement. This hall probe sensor moves radial direction and angular direction by mechanically. The Magnetic field measurement instrumentation measures the field in the range of 5 mm for radial direction and 1 degree for angular direction. Magnetic field was measured with and without cooling. Magnetic field was carried with 4 Gauss without cooling and 0.1 Gauss with cooling. Our developed magnetic field measurement instrumentation has 0.1 Gauss of an error and 0.01 Gauss of resolution over 9 hours.

  Apart from being the first constructed superconducting accelerator, the S2C2 is also the first synchro-cyclotron at IBA. To study the beam dynamics, new computational tools had to be developed dealing with much larger number of turns, the longitudinal capture in the central region and the regenerative extraction. The S2C2 is a medical accelerator requiring a precise control of the beam characteristics so a deep understanding of beam dynamics is mandatory. Our simulation strategy allows to gain important insight in the acceleration process and beam characteristics: the beam emittance and energy spread, beam losses, effects of coil misalignments, median plane errors, resonances, etc. The simulation tools are split in three parts. At first, protons are tracked from the source up to about 3 MeV with the in-house tracking code AOC. In a second part, only the energy, RF phase and orbit centers are tracked as a function of time. Finally, a detailed tracking from 225 MeV up to extraction is performed with AOC. Simulations are compared to experimental observations during in-factory testing and commissioning of the first S2C2 installed in Nice, France.

Cyclotrons are quite often to be used to accelerate different hydrogen ion beams with high intensity for different purposes around the World. At Peking University (PKU), special efforts were made on developing compact 2.45 GHz microwave driven ion sources with permanent magnets to generate high intensity H+, H2+, H3+ and H− ion beams as well as other ion beams. For the positive ion beam, we can easily produce a 120 mA hydrogen ion beam with H+ fraction higher than 92% with a PKU standard 2.45 GHz ECR ion source. Its diameter is about 100 mm, its hight is about 100 mm. Also we have got 40 mA H2+ beam and 20 mA H3+ beam with a specific designed 2.45 GHz ECR ion source under different operation condition. The fractions of H2+ and H3+ are higher than 50% within the mixed hydrogen ion beams for each case. Recently, a Cs-free volume H− source based on 2.45 GHz microwave was developed successfully in our lab. It can generate 45 mA H− beam with duty factor of 10% and a 29 mA beam at DC mode at 35 keV. Its operation duty factor can vary from 1% to 100% and its power efficiency is about 20 mA/kW. Details of these sources will be presented in the paper.

THP05 Beam Intensity Modulation Capabilities for Varian's ProBeam® Isochronous Cyclotron operation, cyclotron, ion, ion-source 313
 
  • S. Busold, H. Röcken
    VMS-PT, Troisdorf, Germany
  
  Varian's ProBeam 250 MeV superconducting proton cyclotron is an isochronous cyclotron for radiological applications using pencil beam scanning mode and thus provides continuous beam (at its fundamental frequency of 72 MHz). In its clinical operation mode up to 800 nA of proton beam are specified and routinely extracted. Even more can be extracted in technical mode. The cold cathode Penning ion source provides enough protons to reach this current, and a layer-to-layer intensity modulation of the scanned beam is realized with an internal electrostatic deflector, which is used to vary the extracted beam current between maximum and zero. However, for research applications there is sometimes the request for higher flexibility, in particular for higher possible beam intensities and faster beam intensity modulation. In order to explore possibilities of the machine for such research modes, experimental investigations have been performed: Pulsed beams with repetition rates of up to 2 kHz and variable pulse lengths down to 4 μs as well as peak currents during pulse of up to 30 μA are in the accessible range with only changes at power supply level.

  The RIKEN K-70 AVF cyclotron has been operated since 1989 and is used as a stand-alone machine and an injector to the RI-beam factory (RIBF). It is operated only in the RF harmonics (H) equal to 2 presently, and the maximum beam energies are restricted to be within 14 MeV for protons and 12.5 MeV/u for M/Q = 2 ions. In order to meet the usersÂ’ requests of beam energy upgrade, the beam simulation studies on the H=1 operation were made, and the central region was modified; these results were already reported in this conference of 2010. In this paper, we will analyze the difference in the transmission efficiency between the beam simulation and measured data in the H=2 operation after the modification of the central region. Moreover, we will also mention the result on the acceleration test of protons at higher energies in the H=1 operation.

THP16 Beam Based Calibration Measurements at the PSI Cyclotron Facility extraction, cyclotron, survey, space-charge 342
 
  • C. Baumgarten
    PSI, Villigen PSI, Switzerland
  
  The PSI cyclotron facility is in operation since four decades. Even though the design details of the original machine are well documented, doubts may remain, if all changes of the most relevant devices during 40 years of operation are known with certainty. Furthermore some measurements like magnetic field mappings and central region alignment measurements can be done only during the construction and assembly phase either for mechanical reasons, due to limited shutdown or maintenance periods or because of the activation of components. Therefore it is important to develop methods that allow to check important parameters during beam operation without a disassembling of components. An effective method to test the consistency of the data is based on the combination of beam tracking simulations and beam based measurements. We present some beam based alignment and calibration measurements concerning collimator positions, Dee voltage distributions, turn patterns, beam energy and trim coil field profiles using measurements of radial probes, phase pickups and profile monitors.

THP17 Automated Documentation of Tunes in the Beam Lines of the COMET Cyclotron software, cyclotron, diagnostics, beam-diagnostic 345
 
  • R. Dölling
    PSI, Villigen PSI, Switzerland
  
  The proton beam from the COMET cyclotron can be transported to three gantries and two horizontal lines. The beam energy is adjusted by a variable degrader. For each branch several "tunes" are defined, each listing the previously evaluated magnet, degrader and collimator settings for a certain beam energy. The beam quality at the end stations is routinely checked meticulously in the frame of treatment quality assurance. Independently of this, software has been developed (in the frame of the machine control system) to collect, for series of tunes, all available information on the beam and on the machine settings in the active beam line. Routinely used, this allows a close observation of the stability and reproducibility of the machine and keeps ready consistent data sets for detailed studies. This tool can also be used to collect, in a short space of time, extensive data for beam dynamics simulations with OPAL or optimisation procedures based thereon, to verify the beam line performance after changes to hardware or software, or to check the functionality of the beam diagnostics. The data set characterising a single tune is organised systematically, allowing to share data viewers with standard beam diagnostics.

THP19 Operational Status of the University of Washington Medical Cyclotron Facility neutron, controls, radiation, cyclotron 351
 
  • R.C. Emery, E.F. Dorman
    University of Washington Medical Center, Seattle, Washington, USA
  
  The University of Washington Medical Cyclotron Facility (UWMCF) is built around a Scanditronix MC-50 compact cyclotron that was commissioned 1983 and that has been in continual use since. Its primary purpose is the production of 50.5 MeV protons for fast neutron therapy. While this proton energy is too low for proton therapy, it is ideal for research in small animal models. In addition to the protons used for fast neutron therapy and proton therapy research, UWMCF is able to accelerate other particles at variable energies. This makes it ideal for medical isotope research, including isotopes such as 211At, 186Re, and 117mSn that are being developed to target and treat metastatic disease at the cellular level. Most recent upgrades to the facility have been to the control systems. The original accelerator and therapy control systems were run on a DEC PDP-11 with a custom centralized i/o system built around the Z80 processor and chipset. Over the last 10 years we have continually been upgrading the controls while remaining operational, moving to a distributed system developed with the open source Experimental Physics and Industrial Control System (EPICS) toolkit.

  An ISOL system has been developed for providing neutron-rich RI beam to multi-disciplinary users by Rare Isotope Science Project (RISP) of the Institute for Basic Science (IBS) in Korea. The ISOL system is composed of proton driver, target/ion source station, mass separator, charge breeder, and A/q separator. A selected beam of interest is then injected into re-accelerator, which is a superconducting linac. A 70-MeV proton cyclotron was chosen as the proton driver to induce direct fission of UCx target. The final goal of beam power on target is 70 kW, which will be achieved gradually from 10 kW during post-RISP. Commercial H− compact cyclotrons and high-intensity separated cyclotrons have been considered for its extension of multi-purpose uses. In this paper, the specifications of the cyclotrons along with concerned issues and the status of our procurement plan will be presented.

  The accelerator complex using FFAG synchrotrons at KURRI* has been operated for the ADSR** experiments connecting the 100 MeV proton beam line with the research reactor facility so called KUCA*** since 2009. Fruitful results have been produced for the reactor physics using various configurations of the nuclear fuel core and variations of the neutron production target. Since higher energy beams such as 300 - 500 MeV are desired for the further study of the ADSR system, we are investigating the energy upgrade possibility of the accelerator complex. One of the candidates is to construct a new FFAG ring which adopts continuous acceleration with fixed frequency (serpentine acceleration) outside of the existing. These higher energy beams can be used for neutron or muon production experiments as well as ADSR study.

FRA01 Single Stage Cyclotron for an ADS Demonstrator cyclotron, extraction, acceleration, injection 387
 
  • P. Mandrillon, M. Conjat
    AIMA, Nice, France
  
  In order to cope with the challenge of an industrial ADS driver demonstrator in the range of 3 to 4 MWatt nominal driving power, it is mandatory to propose an accelerator design able to address highly demanding criteria which are a challenge for high power accelerator designers: the number of beam trips per year and the mean down-time per beam interruption should be drastically reduced. Taking into account the outstanding performances of the PSI ring cyclotrons, it is clear that cyclotrons are competitive challengers to high power linacs. The preliminary design studies of the Single Stage Cyclotron Driver of the AIMA Company could be an attractive solution in terms of cost effectiveness, reliability and power efficiency. Some critical aspects of this design will be presented in this paper.

  In 2013 the SPES (Selective Production of Exotic Species) project has entered in the construction phase at Laboratori Nazionali di Legnaro (LNL). The project, whose main goal is the research in nuclear physics with Radioactive Beams, has foreseen the construction of a new building hosting the accelerator able to deliver protons up the energy of 70 MeV and 50kW of beam power to be used as a primary beam for the ISOL source and for a production beam for other applications. The new facility design has been expanded and upgraded for taking advantage of the dual simultaneous extraction of beams from the Cyclotron in order to provide a multipurpose high intensity irradiation facility. Today the new facility is partially installed and the Cyclotron supplied by BEST Theratronics company (CANADA) with the related beam transport lines are under commissioning. The status of the commissioning of the high power accelerator and the capabilities of the facility as multipurpose high intensity proton beam laboratory will be presented.

  A proof-of-principle test-stand for proton radiography is under construction at China Institute of Atomic Energy (CIAE). This test-stand will utilize the 100 MeV proton beam provided by the compact cyclotron CYCIAE-100, which has been built in the year of 2014, to radiograph thin static objects. The assembling of the test-stand components is finished by now. We will carry out the first proton radiography experiment in this July and hopefully we can get the first image before the opening of this conference. In this paper, the designing, constructing and commissioning of the proton radiography system will be described and the experiment result will be presented and discussed.
