Description
A 10 GHz compact Electron Cyclotron Resonance Ion Source (ECRIS) with all permanent magnets (Kei2-source) was developed for high-energy carbon-ion therapy. Parameters of the Kei2-source have been optimized for the production of C4+ based on experience at the 10 GHz NIRS-ECR ion source and a previous prototype compact source (Kei-source). The maximum beam intensity of C4+ was obtained to be 530 μA under an extraction voltage of 40 kV. In order to increase the intensity of highly charged carbon ion (C4+ and C5+), we employed gas-mixing technique. Usually, carbon molecular gases are used for production of the carbon ions. In this experiment, the CH4, CD4, C4H10, C4D10. C2H2 and C2D2 gases were tested. The experimental results of gas-mixing described in this paper. (author)
