  We have been improving a beam quality of the TIARA (Takasaki Ion accelerators for Advanced Radiation Application) cyclotron to form a heavy-ion microbeam with a spot size about 1 μm. The microbeam is used to irradiate such as living cells and semiconductor devices. In order to form the microbeam using focusing lenses, an energy spread on the order of 10-4 is required to eliminate chromatic aberration in the focusing lenses. A flat-top acceleration system using the fifth-harmonic frequency of the acceleration frequency was installed in the cyclotron to reduce the energy spread. In addition, a new center region, a magnetic field stabilization system and an acceleration phase control technique were developed to provide the microbeam stably for beam users. The energy spread of a 260 MeV Ne beam was reduced to 0.05% by the flat-top acceleration, and the microbeam with a spot size of approximately 1 um was successfully formed. However it takes about 8 h to tune the cyclotron and the focusing lenses. A cocktail beam acceleration technique was introduced to quickly change the microbeam to the other one within 0.5 h, and several microbeams can be used in a beam time as a result.

  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.

  Short-living radioisotopes synthesized in a cyclotron are predominantly used in nuclear medicine diagnostics and therapy. Although technical applications are less common, radioactively marked materials are of high relevance in wear and oil consumption measurements at engine test stands. The oil consumption was determined in the exhaust steam by labelling the oil with radioactive substances for several decades. This was carried out by a time consuming process via catalytic exchange or individual labelling of each oil fraction. In contrast, easily accessible nanoparticles conjugated with radioisotopes could highly improve the dispersibility in the oil. In this study, 123I-Iodide with a short half life of 13.5 h is generated by proton irradiation of a xenon target at a cyclotron, before halide exchange of benzyl chloride reveals the technical relevant 123I-benzyl iodide, which is conjugated to gold nanoparticles in the oil. These nanoparticles are successfully synthesized by simple and rapid pulsed laser ablation of a gold foil in different viscous olefins. Overall this approach represents a new method for radionuclide imaging of engine oil in combustion engines.

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.

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.

MOP16 Beam Optics Considerations for Isotope Production at the PSI Cyclotron Facility 95
  • H. Zhang, J. Grillenberger, M. Seidel
    PSI, Villigen PSI, Switzerland
  The isotope production beam line starts with an electrostatic beam splitter, which peels a beam of a few tens of microamperes from a main beam of high intensity up to 2.4 milliamperes. The beam optics has to be fitted with the specifications such as beam size and intensity for a variety of isotope productions. Due to the parasitic nature of the beam line, the beam optics also has to be adjusted along with an occasional change on the main beam intensity. Aiming at an efficient and reliable isotope production, the beam optics is followed on daily base. The operational experience together with the prospect of future development is presented.

  A newly developed fast digital spectrometer for neutron spectroscopy is presented. A pulse shape discrimination (PSD) performance of the spectrometer has been evaluated within two experiments with different neutron energies. A modular design of the spectrometer allows a variety of measurements in mixed radiation fields. The detector signal output is connected to an analog input amplifier and split into two channels with a different gain. Each signal channel is digitized by a fast analog digital converter. The digital channels are merged into one composite channel with a higher digital resolution in a wide dynamic range of energies. The experimental measurements of secondary neutrons were carried out in the laboratory of Van de Graaff accelerator and at the Proton Therapy Center in Prague. A detector with liquid scintillator NE-213 was employed in both experiments. Secondary neutrons with maximum kinetic energy of 17 MeV were produced. In a workplace of the Proton Therapy Center, secondary neutrons were generated during the interaction of the primary proton beam of energies in the range of 100 to 200 MeV with a plastic phantom.

    FZJ, Jülich, Germany
  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.

    KAERI, Daejon, Republic of Korea
  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.

Rare isotopes are produced at the NSCL by projectile fragmentation at energies of ~100 MeV/u. The NSCL has successfully used linear gas stopping cells for more than a decade to decelerate projectile fragments to the keV range; first for experiments at low-energy and more recently for reacceleration. A novel reverse-cyclotron has been constructed by the NSCL based on a superconducting sectored-cyclotron magnet and LN2-cooled He gas to confine and slow down the fragments. Efficient stopping is predicted even for light ions that are difficult to thermalize in linear gas cells. The thermalized ions are transported to the center by a radial RF-carpet system, extracted through the yoke with an ion conveyor and accelerated to <60 keV for delivery to users. Measured field profiles have confirmed field calculations. The cryogenic beam-stopping chamber has been installed inside the magnet. The RF ion-guiding components have been tested successfully offline and are being prepared for low-energy ion-transport tests inside the magnet. A summary of the expected performance, the status of the machine, and results from recent low-energy transport tests will be presented.

TUD01 Compact Medical Cyclotrons and their use for Radioisotope Production and Multi-disciplinary Research 229
  • S. Braccini
    LHEP, Bern, Switzerland
  Compact medical cyclotrons are conceived for radioisotope production in a hospital-based environment. Their design in terms of field shape, stability and RF is aimed at obtaining high intensity (~150 microamps) beams at kinetic energies of the order of 20 MeV. To guarantee high performances, an optimization procedure during the commissioning phase is crucial as well as a regular preventive maintenance. Beyond radioisotope production, these accelerators can be the heart of a multi-disciplinary research facility once access to the beam area and beams down to the pA range are possible. The first requirement can be achieved by means of an external beam transport line, which leads the beam to a second bunker with independent access. Currents down to the pA range can be obtained by specific ion source, RF and magnetic field tuning procedures, opening the way to nuclear and detector physics, radiation protection, radiation bio-physics and ion beam analysis developments. On the basis of the experience gained with the cyclotron at the Bern University Hospital, the accelerator physics aspects of compact medical cyclotrons will be discussed together with their scientific potential.

The multi-particle cyclotron C70 Arronax is fully running since 2010 and its RF run time has increased up to 4400 hours in 2015. The accelerator is used for a wide variety of experiments (physics cross-sections, radiolysis, radiobiology) and radio-isotope productions. This requires runs with 7 orders of intensity range from a few pA up to 350 μA and a large range of particles energy. Machine and beamline studies are continuously needed. For example magnet intensity scan inside the cyclotron and in the beamlines, respectively with compensation coils and the quadrupoles have been done. These scans caracterise performances of the machine and help both operations and mitigation of particle losses. Additionally beam loss monitors and control systems are being devised to support further the high intensity and precision requirements on the runs. Also a pulsed train alpha beam system located in the injection has been designed. The proof of principle with a dedicated run has been performed. The results of the machine studies and status of these developments are presented in this paper.

  The GANIL facility (Grand Accélérateur National dÂ’Ions Lourds) at Caen produces and accelerates stable ion beams since 1982 for nuclear physics, atomic physics, and radiobiology and material irradiation. Nowadays, an intense exotic beam is produced by the Isotope Separation On-Line method at the SPIRAL1 facility (being upgraded to extend the range of radioactive ions) or by fragmentation using LISE spectrometer. The review of the operation from 2001 to 2016 will be presented, with a focus on last year achievements and difficulties.

  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.
