| Abstract |
Japan Proton Accelerator Research Complex (J-PARC) accelerators have been having over 10 years of operation experience. In 2006, the J-PARC linac started beam operation with an energy of 181 MeV. To realize the nominal performance of 1 MW at 3 GeV Rapid Cycling Synchrotron (RCS) and 0.75 MW at a 30 GeV Main Ring synchrotron (MR), the linac energy was upgrade to 400 MeV by adding an annular-ring coupled structure linac, and the beam current was also upgraded from 30 to 50 mA by replacing a new ion source and an RFQ. After the upgrade, the RCS demonstrated 1MW equivalent beam operation and currently operates 400 kW for the Material and Life Science Facility. The MR beam power is increasing and becomes about 480 kW beam to the Neutrino Facility and about 50 kW at the Hadron Experimental Facility. Further upgrade plan of 1.5 MW beam power from the RCS is now in consideration. To achieve the plan, it is necessary to increase by about 20 % both beam current and pulse length at the linac. The detail process in the past upgrade and the possibility for further upgrade at the linac will be presented in this talk.
