Operation resumption of the J-PARC main ring

J-PARC Center


  We are pleased to announce that we have completed replacement of the damaged coil, and resumed beam operation of J-PARC main ring from November 7.

  As mentioned before, on April 24, 2019, a failure of the bending magnet B15D in the beam transport line from the RCS to the MR stopped beam operation.

  We deeply apologize once again for the inconvenience this may cause, to any users of Hadron/Neutrino experimental facilities.
