	Beam transmission optimization and losses characterization, where beam stripping interactions are a key issue, play an important role in the design and operation of compact cyclotrons. A beam stripping model has been implemented in the three-dimensional object-oriented parallel code OPAL-cycl, a flavor of the OPAL framework. The model includes Monte Carlo methods for interaction with residual gas and dissociation by electromagnetic stripping. The model has been verified with theoretical models and it has been applied to the AMIT cyclotron according to design conditions.

TUP009	Cyclotron Cavity Pollution Recovery	cavity, cyclotron, multipactoring, vacuum	169
	J. Dabin, B. Adant, P. Cailliau, K. Ellis, E. Forton, J. Mandrillon, T.S. Ponter, P. Verbruggen IBA, Louvain-la-Neuve, Belgium
	In a cyclotron, RF cavities are usually among the most reliable subsystems, provided minimal care and maintenance. Nevertheless, several parameters may affect cavity performance after several years of operation. To name a few typical causes of degradation are: decreasing vacuum quality, various gas loads or gas qualities triggering adverse effects, deposition of highly emissive material on the cavity due to overheating of components like pass-through connectors, accidental use of chemicals or not-suitable greases. The cavity status can be monitored but, in the worst cases, the RF tuning may become difficult and it is important to apply methods in order to recover a better cavity Q-factor. In this paper, cases of cavity pollution will be shown, their potential root causes discussed and some recovery methods described.

TUP028	Bremsstrahlung Photons Emission in 28-GHz Electron Cyclotron Resonance Plasma	ECR, photon, ion-source, detector	219

	Radial measurements of bremsstrahlung photons show high-energy intensity beyond a critical energy from electron cyclotron resonance (ECR) heating and its nature is not well understood so far. For the first time we have measured the bremsstrahlung photons energy intensity from 28-GHz ECR ion source at Busan Center of KBSI. Three round type NaI(Tl) detectors were used to measure the bremsstrahlung photons emitted at the center of the ECRIS at the same timeThe ECR ion source was operated at Radiofrequency (RF) power of 1 kW to extract 16O beam with a dominant fraction of O³⁺.We studied possible systematic uncertainties from different characteristics among the three NaI(Tl) detectors by repeating measurements alternatively. Geant4 simulation was performed to take the geometrical acceptance and energy-dependent detection efficiency into account due to large non-uniformity in the material budget. We extracted true bremsstrahlung energy spectra from the 28-GHz ECR ion source using the inverse-matrix unfolding method. The high energy intensities of the bremsstrahlung photons at the center of the ECRIS were explained by the internal structure and shape of ECR plasma.

THB03	Conceptual Design of TR¹⁰⁰⁺: An Innovative Superconducting Cyclotron for Commercial Isotopes Production	cyclotron, proton, extraction, acceleration	298
	Y.-N. Rao, R.A. Baartman, Y. Bylinskii, T. Planche, L.G. Zhang TRIUMF, Vancouver, Canada
	Utilizing dedicated cyclotrons to produce medical isotopes is an arising technology in hospitals across Canada. Thus, in January 2015, the CycloMed99 team, led by TRIUMF, demonstrated a breakthrough in producing the world’s most highly used medical isotope, technetium-99m (Tc-99m), on existing medical cyclotrons. Now we propose to design an innovative superconducting cyclotron for production of commercially valuable radioisotopes. This project will be focusing on a proton energy of 70-150 MeV and proton current of 2 mA. In this energy range, numerous increasingly demanded radioÂnuclides can be produced, either as parent nuclei for generator use, or directly as a active pharmaceutical ingredient, e.g. Strontium-82 (Sr-82), Actinium-235 (Ac-235) and Bismuth-213 (Bi-213). Our machine shall be designed to accelerate H²⁺, by injection from external ion source and extraction by stripping. This shall allow to simultaneously extract multiple cw proton beams of variable currents and potentially variable energies to multiple experimental stations with extremely high extraction efficiency. The basic parameters of the machine and the simulations of stripping extraction will be presented.

	Funding: This study is supported by three programs of the Agence Nationale de la Recherche, ANR-17-CE31-0015, ANR- 11-EQPX-0004 and the LABEX P2IO. The PEPITES project* aims at realizing an operational prototype of an ultra-thin, radiation-resistant profiler able to permanently operate on mid-energy (O(100 MeV)) charged particle accelerators. PEPITES uses secondary electron emission (SEE) for the signal because it requires only a minimal thickness of material (10 nm); very linear, it also offers a great dynamic. The lateral beam profile is sampled using segmented electrodes, constructed by thin film methods. Gold strips, as thin as the electrical conductivity allows (~ 50 nm), are deposited on an as thin as possible insulating substrate. When crossing the gold, the beam ejects the electrons by SEE, the current thus formed in each strip allows the sampling. The technique was validated at ARRONAX with 68 MeV proton beams for intensities from 100 fA to 10 nA. SEE is characterized up to 100 nA at ARRONAX and medical energies at CPO*. Electrodes were subjected to doses of up to 10⁹ Gy without showing significant degradation. A demonstrator with dedicated electronics (CEA) will be installed at ARRONAX and used routinely. The performances of the system and its behavior over time will thus be characterized. LLR, ARRONAX cyclotron and CEA **Orsay Protontherapy Center (Institut Curie)

	ECR Ion Sources are deemed to be among the most performing ion sources feeding particle accelerators, cyclotrons in particular. Improvements of their performances strictly depend on the knowledge of plasma physics in compact magnetic traps. The paper will comment on the results obtained by the INFN-LNS team and international collaborators by means of a multi-diagnostics setup able to monitor the evolution in space and time of several plasma parameters, simultaneously with beam extraction and analysis in the LEBT, in single vs. double frequency operations, including the RF power and magnetic field scalings, and exploring regimes dominated by plasma turbulence. The results are relevant for the operations of existing ion sources and for the design of new ones. Compact magnetic traps fashioned in a similar way of ECRISs can be considered as an experimental environment by itself: we are exploring this opportunity relying to the in-plasma measurements of radionuclides lifetimes (in particular, beta-decaying elements): CosmoChronometers or nuclei involved in the s-process nucleosynthesis are among the case studies, opening new perspectives in the nuclear astrophysics field.

FRA04	Cyclotrons Based Facilities for Single Event Effects Testing of Spacecraft Electronics	radiation, heavy-ion, detector, proton	348

	Space radiation is the main factor limiting the operation time of the onboard equipment of the spacecraft due to the radiation effects occurring in the electronic components. With a decrease in the size of semiconductor structures, the sensitivity to the effects of individual nuclear particles increases and hitting one such particle can cause an upset or even failure of a component or system as a whole. Since the phenomenon occurs due to the impact of a separate particle, these radiation effects are called Single Event Effects (SEE). To be sure that the electronic component is operational in space, ground tests are necessary. SEE tests are carried out on test facilities that allow accelerating heavy ions from C to Bi to energies from 3 to a few dozen MeV/A. Cyclotrons are best suited for this purpose. In this paper, the installations created by request of ISDE based on the cyclotrons of FLNR JINR are described.
