| Research Abstract |
It is planned to measure muon spin polarization precisely in the J-PARC E06 experiment (Search for T violation in Kaon Decays). We developed a muon polarimeter for this experiment. The polarimeter consists of muon stoppers to stop incident moonbeams and drift chambers to detect decay positrons, and a muon field magnet. According to simulation calculations, a 1/5 model and then a full-size model have been constructed as prototypes and tested with an actual muon beam. Good performance could be confirmed and important data were collected.
