| Abstract |
The beam commissioning of J-PARC started in November, 2006. Since then, the timing system of J-PARC accelerator complex has contributed stable beam operations of three accelerators: a 400-MeV linac (LI), a 3-GeV rapid cycling synchrotron (RCS), and a 50-GeV synchrotron (MR). The timing system handles two different repetition cycles: 25 Hz for LI and RCS, and 2.48-6.00 sec. for MR (MR cycle). In addition, the timing system is capable to provide beams to two different experimental facilities in single MR cycle: Material and Life Science Experimental Facility (MLF) and Neutrino Experimental Facility (NU), or, MLF and Hadron Experimental Facility (HD). Recently, a plan to introduce a new facility, Accelerator-Driven Transmutation Experimental Facility (ADS), around 2018, has been discussed. Studies for the timing system upgrade are started: change of the master repetition rate from 25Hz to 50 Hz, and a scheme to provide beams to three different experimental facilities in single MR cycle (MLF, NU and ADS or MLF, HD and ADS). This paper reviews the 8-year operation experience of the J-PARC timing system, followed by a present perspective of upgrade studies.
