小型ECRイオン源の性能向上のための開発 村松, 正幸 村松 正幸 metadata only access Kei2アブストラクト A compact electron cyclotron resonance ion source (ECRIS), so-colled Kei2, has been developed for high energy carbon ion therapy facility. It based on experimental studies for production of carbon 4+ ions with a 10 GHz ECR source at the Heavy Ion Medical Accelerator in Chiba (HIMAC), so-called NIRS-ECR, the field distribution of the mirror magnet for Kei2 was designed. A microwave source with the traveling-wave-tube (TWT) was adopted for Kei2, with a frequency range and maximum power of 9.75 - 10.25 GHz and 750 W, respectively. The Kei2 and prototype injector were installed in the HIMAC facility in 2009. Improvement of the Kei2 is described in this paper. 第7回日本加速器学会 2010-08-06 jpn conference object https://repo.qst.go.jp/records/70206
