Development of intense high-energy noble gas ion beams from in-terminal ion injector of tandem accelerator using an ECR ion source

摘要

An ECRIS-based heavy ion injector was constructed in the high-voltage terminal of JAEA-Tokai Tandem Accelerator to develop new beam species of highly charged noble gas ions. This work was associated with a lot of development to operate the ion source on the 20UR Pelletron high voltage terminal in high pressure SF_6 gas environment. Highly charged ions of N, 0, Ne, Ar, Kr and Xe have been accelerated satisfactorily. Operating data integrated during many years long beam delivery service are summarized.
