| Abstract |
MedAustron is a synchrotron based ion beam therapy center for proton (62-250 MeV) and carbon ion (120-400 MeV/n) treatments. The MedAustron synchrotron uses a betatron core driven slow extraction scheme based on a third order resonance. The commissioning of the extraction from the synchrotron involved the setup of the correct orbit and optics at flattop. In order to maximize the momentum spread before extraction and optimize spill structure the RF system enforces a so called RF-phase jump to the unstable phase. Different scenarios were simulated using MADX-PTC [1] in combination with Python to overcome the static nature of PTC. Simulations have shown that the initial phase of the beam and a finite time to jump to the unstable fix point have a strong impact on the performance. Using a high frequency intensity monitor in the extraction channel (QIM), the spill structure was analysed and used for optimization. Simulation and measurements of the procedure are presented.
