Description
The Tohoku earthquake in March 2011 caused significant damage to the Japan Proton Accelerator Research Complex (J-PARC) linac and forced us to shutdown the accelerator for nearly nine months. After a significant effort for its restoration, we resumed beam operation of the J-PARC linac in December 2011. Since the resumption of beam operation, we have been suffering from beam-losses which were not observed before the earthquake. Tackling the beam-loss issues, we have finally reached the same beam power for user operation as before the earthquake. In this paper, we present our experience with the beam start-up tuning after the earthquake, with emphasis on beam-loss mitigation efforts.
