| 内容記述 | A technical realization for a positron emitter 11C-beam (R.I.) as an accelerating-beam has been studies at NIRS-HIMAC in order to apply for a heavy-ion therapy. In connection with this study, ionization efficiency of CO2-gas in the ECR type of ion source is a serious question. In the process of ionization, C2+ ion beam is focused on producing in the ECR, that is expected to be a highly intensity compared with other charge states of the ions. In our test result, at this point, the ionization efficiency was about 1% or more for 12C2+ beam extracted from the ECR. In order to obtain more high efficiency residual gas spectrum has been measured and analyzed. The results show that more increase the microwave power and more decrease the gas flow-rate. Details of the study are presented. | |||||
