| 内容記述 | A technical realization for a position emitter 11C-beam(R.I.) as an accelerating -beam has studied at NIRS-HIMAC in order to apply for a heavy-ion therapy.In this study,the calculation result shows the order of 1E+9ppp of 11C2+ ions will be extracted from the calculation result shows the order of 1E+9ppp of 11C2+ ions will be extracted from the ion source during 18minutes at 3.3-second intervals with 1-msec beam pulse under one-Ci of 11C-production ,where the ionization efficiency of the.11C2+ion is assumed to be 1percent.So that the first object in this study is to measure an ionization sfficiebcy of 11C-gas in an ECR ion source.In order to investigate the efficiency CH4-gas of 0.07atm/cc/min was used, and equipped a suitable Q-mass gas analyzing system to measure residual gas components evacuated from the ECR. Result show that almost 1% of the ionization efficiency was observed for 2+ and 4+ of 12C-ions, in the measurement of the charge spectrum.On the other hand,unexpected phenomenon was also observed on the ionization process in the ECR.In this paper details of the phenomenon are analyzed. | |||||
