| Outline of Final Research Achievements |
A RICH type detector has been developed to identify secondary beam particles for the high-momentum beam line at the J-PARC Hadron Facility. It enable us to study cascade baryons systematically which are produced with a 4 GeV/c kaon beam.
The production rate of beam pions are higher by three orders of magnitude compared with that of kaons. Therefore, a differential Cerenkov detector is needed to actively identify beam kaons. At the beam momentum of 4 GeV/c, a suitable radiator are aerogels with an refractive index of 1.05. The Cerenkov ring image is detected with Multi-Pixel Photon Counter (MPPC). As a result of a beam test for a prototype detecter, the Cerenkov angle resolution of 3mradian was achieved to demonstrate that beam kaons are separated from pions with 8sigma sensitivity.
