J-PARC Center May 27, 2008 MR: Successful injection of 3GeV proton beam, RF captured and extraction   At 22:27 of May 22nd 2008, the 3 GeV proton beams from the RCS (3GeV proton synchrotron) were successfully injected into the Main Ring (50GeV proton synchrotron). The beam was captured by RF and extracted to the beam dump after 1000 turns. The day after, the beam storage time was extended up to 1 second. It is the major milestone for the J-PARC. The next step is to accelerate beams to 30GeV (Phase I) and to extract beams to the experiment targets, which will start in the end of this year.
