Description

Patient irradiation with mixed 4He2+ and 12C6+ ion beams is a promising proposal for online monitoring in carbon ion therapy. Over the past years, major developments have enabled the generation of such beams at MedAustron, where they are now used in accelerator, detector, and medical physics research projects.

This contribution summarizes the key innovations that made this achievement possible. Among these are a new double multiturn injection scheme for merging helium and carbon ion beams in the synchrotron, concepts for simultaneous slow extraction of both ion species, and dedicated diagnostic tools for mixed beam characterization in the accelerator and experimental room. Together, these advances pave the way for continued progress in the field of mixed ion beam acceleration and application.
