	After 25 years of successful research in the nuclear and radiation physics domain, the KVI-CART research center in Groningen is upgraded and re-established as the PARticle Therapy REsearch Center (PARTREC). Using the superconducting cyclotron AGOR and being embedded within the University Medical Center Groningen, it operates in close collaboration with the Groningen Proton Therapy Center. PARTREC uniquely combines radiation physics, medical physics, biology and radiotherapy research with an R&D program to improve hadron therapy technology and advanced radiation therapy for cancer. A number of further upgrades, scheduled for completion in 2023, will establish a wide range of irradiation modalities, such as pencil beam scanning, shoot-through with high energy protons and SOBP for protons, helium and carbon ions. Delivery of spatial fractionation (GRID) and dose rates over 300 Gy/s (FLASH) are envisioned. In addition, PARTREC delivers a variety of ion beams and infrastructure for radiation hardness experiments conducted by scientific and commercial communities, and nuclear science research in collaboration with the Faculty of Science and Engineering of the University of Groningen.

	Funding: Work supported by the DAE, Government of India. The K500 Superconducting Cyclotron (SCC) has been developed indigenously and commissioned at VECC. The three-phase Radio-Frequency (RF) system of SCC, consists of three half-wave cavities placed vertically 120 deg. apart. Each half-wave cavity has two quarter-wave cylindrical cavities tied together at the centre and symmetrically placed about median plane of the cyclotron. Each quarter-wave cavity is made up of a short circuited non-uniform coaxial transmission line (called "dee-stem") terminated by accelerating electrode (called "Dee"). The SCC, operating in the range 9 to 27 MHz, has amplitude and phase stability within 100 ppm and 0.1 deg. respectively. The overview of all the subsystems of the cyclotron along with low-level RF (LLRF), high and low power RF amplifiers, cavity analysis, absolute Dee voltage measurement using X-ray method, amplitude and phase control loops will be presented in the talk. The commissioning of the cyclotron with first harmonic Nitrogen⁴⁺ beam extracted at 252 MeV, while operating at 14 MHz RF frequency, along with the correction of first harmonic magnetic field error by repositioning the cryostat within 120 micron accuracy, will be discussed briefly.

The cyclotron C70XP is an accelerator built for the production of non-conventional radionuclides for nuclear medicine, research in physics, radio-chemistry and biology. Its injection section has been designed for 4 types of ions (HH⁺, D-, He2+ & H⁻), 3 types of ions reach the end of the beamline (H⁺, He2+ & D⁺) at the maximum energy of 70 MeV (H⁻ & He2+). It is important that regular and standard runs provide similar beam features with a good emittance quality. An investigation, focused on the beam in the injection, cover beam measurements and potential beam geometry constraints. The beam transverse characteristics in the injection line has been studied with an Allison-type emittance meter and a simple instrumented collimator installed inside the injection line . With these 2 devices, it is scrutinized how the beam emittance evolves as a function of settings of the injection magnets and the source parameters . Dependencies found between the emittance, beam hotspots and tunings are discussed, as well as the protection performed by the collimator. Future of this work with a potential collimator design is introduced. F.Poirier and al., ’The Injection and Chopper-Based System at Arronax C70XP Cyclotron’ **F.

TUP17	Beam Dynamics and Space Charge Studies for the InnovaTron Cyclotron	extraction, ion-source, space-charge, plasma	108
	G. D’Agostino, W.J.G.M. Kleeven IBA, Louvain-la-Neuve, Belgium
	At IBA a high-intensity compact self-extracting cyclotron is being studied. There is no dedicated extraction device but instead, a special shaping of the magnetic iron and the use of harmonic coils to create large turn-separation. Proton currents up to 5 mA are aimed for. This would open new ways for large-scale production of medical radioisotopes. The main features of the cyclotron are presented. A major variable of the beam simulations is the space charge effect in the cyclotron center. Using the SCALA-solver of Opera3D, we attempt to find the ion source plasma meniscus and the beam phase space and current extracted from it. With these properties known, we study the bunch formation and acceleration under high space charge condition with our in-house tracking code AOC. We also discuss a new tool that automatizes optimization of cyclotron settings for maximizing beam properties such as extraction efficiency. *Work supported by the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 886190

	The GANIL installation at Caen in France has been operating with warm temperatures cyclotrons for heavy ion beam physics since 1983. The accelerated stables beams widely ranges from Carbon to Uranium beams. Low energy and post accelerated radioactive ion beams are also being provided. The GANIL laboratory has newly increased their different ion beams available with the installation and commissioning of a superconducting linear accelerator ’ SPIRAL 2 and its experimental areas. The construction started in 2011, the first beam was extracted at low energy in late 2014 with pre-acceleration in 2017 and since 2019 the new installation delivers beam for nuclear physics experiments. This paper will cover the commissioning of the SPIRAL 2 installation at GANIL with its superconducting LINAC - but also the latest development of stable and radioactive beams at the cyclotrons.
