It is a major issue for application to detectors at high intensity experiments, such as the Belle II experiment. We succeeded in improving the lifetime of the MCP-PMT by suppressing the residual gas and applying atomic layer deposition. To extend the lifetime further, understanding the mechanism of the photocathode deterioration is essential. Therefore we studied correlations of the amount of ions with the lifetime by analyzing the after-pulse. The results indicate that the cause of the photocathode deterioration could be hydrogen ions, heavy ions (mass number larger than 100), or neutral gas.","PeriodicalId":228570,"journal":{"name":"Proceedings of the 5th International Workshop on New Photon-Detectors (PD18)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116321596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its broad physics program includes nu-cleon decay, neutrinos from astronomical and human-made beam, with the main focus to determine the leptonic CP violation. To detect the weak Cherenkov light generated by neutrino interactions or proton decay, the primary photo-detector candidate are 20-inch “Box & Line” PMTs (Hamamatsu R12860). In order to enlarge Hyper-Kamiokande physics program, the use of multi-PMT modules is considered as a complement of the primary candidates. A multi-PMT Optical Module based on a pressure vessel instrumented with multiple small diameter photosensors, readout electronics and power, offers several advantages as weaker sensitivity to Earth’s magnetic field, increased granularity, reduced dark rate, improved timing resolution and directional information with an almost isotropic field of view. We will present the multi-PMT module developed for Hyper-Kamiokande and its near detector, E61, as well as the measurement of the performances of its individual 3-inch PMTs (R14374).

Thus, a multiple high-energy implantation and rapid thermal annealing process is newly adopted instead of a conventional process to eliminate slip generation during the high temperature annealing. The process condition optimization was done by using technology computer aided design (TCAD) regarding gain and noise performance. The optimized process conditions are obtained by making a flat boron concentration of multiplication region.
