NUCLEAR PHYSICS

Abstract

After the big earthquake in the east part of Japan on March 11, 2011, the beams in the hadron experimental hall at J-PARC have been successfully recovered in February, 2012. The experimental program using pion beams is now on-going with the primary proton beam power of (cid:24) 5 kW. Before a long summer shutdown scheduled in 2013, several experiments in strangeness nuclear physics are going to take data. In this period, we anticipate the beam power would exceed 10 kW and the experiments to use K (cid:0) beams will start. The experimental program is explained briefly. line was performed together with the performance check of the beam-line and SKS spectrometers. A good energy resolution of the spectrometers was confirmed.
