Description
The recent availability of mixed 4He2+ and 12C6+ beams for research on online treatment monitoring in carbon ion therapy is introducing new challenges for slow extraction from synchrotrons. Ideally, the mixed beam should be extracted with a constant helium-to-carbon ratio over the entire spill. This is complicated by species-dependent dynamics: the two ion species feature an effective rigidity offset, which is 0.095 % to 0.135 % across the clinical energy range at MedAustron. Additionally, when generating the mixed beam via sequential synchrotron injection, helium and carbon ions occupy distinct regions in horizontal phase space. This paper summarizes the first experimental experience with dual-species RF knockout (RFKO) extraction at MedAustron.
