One of them, the NIRS-ECR, is a 10GHz ECR ion source, and is mainly operated to produce C4+ ions for the daily clinical treatment. This source realizes good reproducibility and reliability with easy operation. The other source, NIRS-HEC, is an 18GHz ECR ion source, and is expected to produce heavier ion species. The output ion currents of the NIRS-ECR and the NIRS-HEC are 430eA for C4+ and 1.1 emA for Ar8+, respectively.}, pages = {1061--1063}, title = {Status report on electron cyclotron resonance ion sources at the heavy ion medical accelerator in Chiba}, volume = {71}, year = {2000} }
