| Outline of Final Research Achievements |
This study develops a high-granularity scintillator-based calorimeter technology for precision research at next-generation electron-positron collider experiments. We have developed a new SiPM readout technique that solves various technical problems and enables further performance improvement. We have shown that the new SiPM readout technique has the expected performance in terms of light yield position dependence, random noise reduction, and hit position reconstruction. A large full-layer prototype of the scintillator strip calorimeter was constructed and its performance was successfully evaluated through LED and cosmic ray tests. Furthermore, we succeeded in developing an innovative measurement method for SiPM saturation phenomena, which would be a crucial issue in SiPM readout scintillation detectors.
