Abstract

The J-PARC project comprises a 400-MeV linac, a 3-GeV, 1-MW rapid-cycling synchrotron (RCS), a 50-GeV main ring (MR), and experimental facilities using the Sand 50-GeV beams. The J-PARC facility is under construction to be completed by March 2007. The J-PARC accelerators are based upon many newly developed technologies, including the RF system using the cavities load with the magnetic alloy (MA) and the linac components such as the RFQ linac with π-mode stabilizing loops (PISLs), the RF choppers, and others in order to realize their high beam powers. The recent results of the developments of these new technologies and the present status of the construction are reported.
