Description
There are some needs of proton beam of several MeV in energy for the purpose of calibrating charged particle detectors. For that purpose, electrostatic accelerators are usually appropriated, but recently many electrostatic accelerator facilities have been shut down. On the other hand, cyclotrons are too large to use for such calibration. So, a proton generating system which consists of 18 GHz SCECR ion source and deuterated polyethylene target has been developed at the Research Center for Nuclear Physics (RCNP), Osaka University. The ion source provides 20 keV $^{3}$He beam. As a result of $^{3}$He$^{+d}$ reaction, protons of 14.7 MeV can be obtained. These protons are used for detector calibration inside the vacuum chamber on the LEBT of the SCECR ion source. Details of this system will be presented.
