 note = {A technical realization for a positron emitter 11C-beam (R.I.) as an accelerating-beam has been studied at NIRS-HIMAC in order to apply for a heavy-ion therapy. The purpose of the present study is to show how obtain a suitable beam intensity of the 11C-beam extracted from the HIMAC-Synchrotron. In connection with this study, related developments include the production of radioactive isotopes (11C) by cyclotron, gas separation, gas-compression, gas-pulsing and ionization. Further, the residue 11CO2-gas can be reproduced in the ionization process. As the result of a calculation, the order of 108ppp of 11C6+ ions can be extracted from the HIMAC-synchrotron during 18 minutes at 3.3-second intervals with a 1-msec beam pulse under the assumption of that 1Ci of 11C-production. Details of the study are presented., 8th European Conference on Accelerators in Applied Research and Technology},
