History

  J-PARC is a joint project between two organizations, High Energy Accelerator Research Organization (KEK) and Japan Atomic Energy Agency (JAEA).
  The facility is located in Tokai village in the northern region of Ibaraki prefecture, JAPAN.
  Construction started in April 2001, and in the spring of 2009 (end of JFY2008) the Phase 1 project was completed after eight years of construction period.
  Currently, consideration and technology development of the experimental facility for nuclear transmutation research are underway.

JAEA and KEK signs a cooperative agreement on construction and research and development of J-PARC.
Construction of J-PARC facilities starts.

2005 JAEA and KEK signs a cooperative agreement on management of J-PARC.
2006 J-PARC center is established.
2007 Expected energy is achieved at linac and RCS.
2008

Initial target energy (30 GeV) is achieved at MR.
Utilization of the Materials and Life Sciences Facility (MLF) is started.

2009 Utilization of the Hadron and Neutrino Experimental Facility is started.
2011 Operation stops due to the Great East Japan Earthquake.
2012 Operation resumes and shared use starts.
2013 The radioactive material leak accident occurs in the Hadron Experimental Facility on May 23.
2015 Short pulse 1 MW is achieved.
2016 Operation of the MLF resumes with a low power.
2018 Continuous operation with a beam power equivalent to 1 MW is succeeded.
