Description

Within the framework of MEDICIS-Promed, possibilities for hadron therapy with radioactive ion beams are investigated. For preparation of a radioactive $^{11}$C treatment beam, the use of an ISOL-production stage followed by a charge breeding system is considered. In order to better understand the limitations of the charge breeding system, we have performed tests with stable high-intensity CO beams at the REX/HIE-ISOLDE low energy system, consisting of a Penning trap and an Electron Beam Ion Source. Efficiencies for high current throughput are presented along with data on molecular breakup in the buffer gas and ion losses for long holding times of the CO beam in the Penning trap.
