Outline of Final Research Achievements

This research focussed on the development and testing of photo detectors for the Intermediate Water Cherenkov Detector (IWCD) and the initial mechanical design and facility design for the IWCD. Extensive testing of 8-cm diameter photomultiplier tubes (PMTs) was carried out and the performance of different PMT models was characterized. Based on this testing, the primary candidate PMT for the IWCD was chosen. Pressure testing and materials compatibility testing of the vessel in which the PMT will be house under water were also carried out, and the design and materials of the pressure vessel were confirmed. A candidate high voltage power circuit for the PMT was also produced and tested. The initial mechanical design of the IWCD and the design of the IWCD facility were carried out as part of this research project. Based on the results of this design work, the IWCD could be adopted as part of the Hyper-K project, and the Technical Design Report for the IWCD could be completed.

Academic Significance and Societal Importance of the Research Achievements

本研究はハイパーカミオカンデ実験の測定精度を向上することを目的とした検出器の基礎研究を進めるものである。ハイパーカミオカンデはニュートリノ振動などについて世界最先端の研究を行う計画である。ニュートリノ振動の精密測定を実現するためには前置検出器により振動前のニュートリノの特性を理解することが重要な課題である。本研究では、IWCDの設計や技術面の実現性の検証を進め、その成果として、IWCDはハイパーカミオカンデ実験の前置検出器として採用されている。
