Status of J-PARC project

The Japan Proton Accelerator Research Complex (J-PARC) has progressed extensively in the last few years. Successful commissioning of the first stage accelerator linac started on November of 2006, in October of 2007; the 3 GeV synchrotron also successfully accelerated protons up to 3 GeV with 5 kW beam power by a single shot. Following these successes, the first neutron beam was observed from the spallation neutron source at Material and Life Science Facility on May of 2008.
