| Outline of Final Research Achievements |
We developed a cost-effective and robust high-resolution Time-of-Flight detector with Multi-Pixel Photon Counters (MPPCs), which is used for "kaonic nuclear states search experiments" and "S=-2 di-baryon search experiments" at J-PARC. In this work, we developed and established a high-resolution detector with time resolution of less than 100 ps by using series-connected 3 MPPCs read-out on both sides of a plastic scintillator slab. Usage of such the high-resolution detector with cost-effectiveness and robustness becomes increasingly important in the field of nuclear experiments at J-PARC and RIBF.
