| 1 | NIRS的ECR离子源现状(英文)显示文摘Four ECR ion sources have been operated in National Institute of Radiological Sciences(NIRS). Two ECR ion sources supply various ion species for the Heavy Ion Medical Accelerator in Chiba(HIMAC). The 10GHz NIRS-ECR ion source mainly produces C2+ ions for the heavy-ion therapy.Ions of Si,Ar,Fe,Kr and Xe are usually produced by the 18GHz NIRS-HEC ion source for physical and biological experiments.The other two compact ECR ion sources with all permanent magnet configuration have been developed for the new generation carbon therapy facility.One of these,the Kei-source,is a prototype which has been installed to the NIRS-930 cyclotron for axial injection.The other source,Kei2-source,is a demonstration source and utilized for the new generation Linac.In addition,both Kei sources have been used to study fundamental properties. In this paper,present status of the ion sources and recent developments are reported. | M.Muramatsu A.Kitagawa Y.Iwata K.Yamamoto H.Ogawa S.Hojo Y.Sakamoto T.Honma W.Takasugi M.Wakaisami Y.Yoshida T.Kubo Y.Kato S.Biri A.G.Drentje | 2007 | Chinese Physics C2007，31，S1： | 0 |
