| Popis: | 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. Proceedings of the 21st Int.
