TUP02	Cold Cathode Ion Source for IBA CYCLONE®230	164
	P. Cailliau, J.C. Amelia, J. Brison, E. Forton IBA, Louvain-la-Neuve, Belgium M. Conjat, J. Mandrillon, P. Mandrillon AIMA, Nice, France
	At IBA, we use a P.I.G. floating cathode ion source for injection in the CYCLONE®230 cyclotron. The purpose of the project is to investigate how the pre-sent ion source could be replaced by a P.I.G. cold cathodes one with a longer lifetime. Experiments de-scribed in this article were done on a dedicated test setup to benchmark the different modes. A new chimney design has been developed to test cold cath-ode mode in CYCLONE®230 without any other me-chanical modifications.

THB01	The S2C2: From Source to Extraction	285

	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.

FRA01	Single Stage Cyclotron for an ADS Demonstrator	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.
