First test run of beams in J-PARC proton accelerator since earthquake

January 14, 2012

The proton accelerator at J-PARC (Japan Proton Accelerator Research Complex) in Tokai, Japan was affected by the earthquake of March 2011, though not by the tsunami. The damage sustained during the earthquake has now been mostly repaired, and the first test run of proton beams since the earthquake was successfully conducted in the LINAC (linear accelerator) on 9th December 2011. This was an extremely important milestone for the J-PARC accelerator and the T2K experiment. For further information, see .
