Beam Commissioning of J-PARC linac

Masanori Ikegami, J-PARC/KEK
Thursday, September 5, 2:30 PM - Special ASD Seminar
NSCL Lecture Hall

We started the beam commissioning of J-PARC linac in November 2006 and the user operation in December 2008. Since then, we have been continuing the effort to ramp up the beam power while sustaining the user operation. Although the beam operation was interrupted by damages due to a major earthquake in 2011, we recovered the beam operation after nine month restoration effort and resumed the beam power ramp up to reach 300 kW on the neutron target. In this presentation, we review our experience in the beam commissioning with emphasis on the re-commissioning after the earthquake. The recent radioactive material leak accident at J-PARC will also be briefly reported.
