Research Abstract

The 50 GeV proton synchrotron at the Japan Proton Accelerator Research Complex provides the highest-intensity hadron secondary beams we have ever had. We proposed experiments with the high-intensity pion beams. We submitted proposals to produce the neutron-rich hypernuclei (E10) and to study the weak decays of hypernuclei (E22), and these proposals were approved. We successfully developed tracking detectors for the high-intensity beams. We also developed detectors to measure particles from the decays of the hypernuclei. We finished the constructions of the detectors in 2009, and we are ready to start the experiments.
