J-PARC is a multi-purpose research facility for materials and life sciences, nuclear and particle physics, and nuclear engineering. The accelerator complex consists of a 400-MeV linac, a 3-GeV Rapid Cycling Synchrotron (RCS), and a 50-GeV Main Ring synchrotron (MR). To provide MW-class beams at 3 GeV and several 10 GeV while localizing and suppressing beam loss for hands-on maintenance, challenging technologies such as ceramic ducts without water cooling and high field RF system with Magnetic Alloy in RCS, and compact electromagnet Drift-Tube Quadrupoles in the linac were developed. The linac provides stable beam with short down time. RCS recorded 0.21 MW in Sep. 2008 with localized loss at the collimators. The linac will be upgraded to 400 MeV with Annular Coupled Structure linac. In the second construction phase, upgrade of the linac with 600-MeV Super-Conducting Linac for Accelerator-Driven nuclear transmutation System and upgrade of MR to 50 GeV are planned.
