1. 共同利用状況など
【 中性子共同利用実験審査委員会 】
J-PARC物質・生命科学実験施設において高エネルギー加速器研究機構物質構造科学研究所が保有する中性子科学実験装置を用いて行うプロジェクト研究型課題（S1型課題）及び装置調整課題、及び、マルチプローブ課題の審査が、2024年1月9日に開催された中性子共同利用実験審査委員会において行われた。現S1型課題は今年度で5年間の研究期間を終了するので、S1型課題は来年度から5年間を研究期間とする新規課題として申請された。委員会では、まず、新規S1型課題に対して公開でヒヤリングを行い、その後、非公開で審査が行われた。審査結果は2024年3月に開催される物質構造科学研究所運営会議で審議される。
