Overview, Accelerator Development Status and Future of J-PARC

Abstract

The 3-GeV beam accelerated by J-PARC Rapid-Cycling Synchrotron (RCS) was successfully extracted to the beam dump located at the beam transport to the neutron production target. The present status of the J-PARC accelerator development, in particular, that of the RCS, is reported together with the overview and future plan of the J-PARC project. It is presented how the new accelerator technologies developed for the J-PARC will contribute a lot to the world-wide progress of the proton accelerator field.
