Commissioning of the injection beam for the J-PARC RCS

Okabe, Kota

In the Japan Proton Accelerator Research Complex (J-PARC) 3-GeV rapid cycle synchrotron (RCS), supression of the transverse beam halo for the injected beam int the RCS is required to increase the output beam power. Transverse beam matching of the injection beam at the Linac-RCS beam transport line (L3BT) is one of the most useful method to reduce a beam loss in the RCS. Results of the beam commissioning for high intensity operation at the RCS, beam loss in the RCS and halo compornent of the extracted beam from the RCS ware supressed by the transverce matching methd. In this presentation, we will report the injection beam matching method at the L3BT and discuss the space charge phenomena about the high intensity beam.
