Outline of Final Research Achievements

The J-PARC MLF in Tokai-mura, Ibaraki Prefecture, is the world's highest intensity pulsed neutron source facility. 3-He position sensitive neutron detectors (3He-PSNDs) are widely used at MLF. However, in recent years, in addition to availability issues, there have been problems in detector performance such as rate characteristics and radiation tolerance. In this study, an alternative detector to the 3He-PSND, the nTGC, was developed.

Academic Significance and Societal Importance of the Research Achievements

本研究で開発されたnTGCはμ粒子トリガー用のガス放射線検出器TGCをベースとしている。TGCはレート特性と耐放射線特性に優れており、3He-PSNDの欠点をカバーすることが期待できる。本研究は、世界中でおこなわれている3He-PSNDの代替検出器開発の1つであり、今後さらに発展することが期待されている。また、本研究で開発を進めた読み出しモジュールは他の中性子検出器にも使用できる有用なものである。
