Outline of Final Research Achievements

Searches for muon rare decays are drawing attention as a clue to the physics beyond the Standard Model in particle physics. We have developed a detector system to diagnose a muon beam for the search of the muon to electron conversion using a high-intensity muon beam. The muon beam in such purpose has a wide momentum range in low momentum region, thus we developed and successfully constructed a system composed of ultra-low material tracking detector using straw tubes and LYSO crystal calorimeter with fast response and good energy resolution. We conducted a performance evaluation test of this system in this research program.
