装置整備

BL21 ラジアルコリメータの整備・完成

J-PARCの高強度中性子線を生かす上で、バックグラウンドの低減が不可欠である。物性を理解する上で極低温・高温下といった様々な試料環境における実験が重要であるが、熱遮蔽や高真空保持ための真空容器などの構造体によりバックグラウンドが高くなる。こうした試料環境由来のバックグラウンドの軽減を目的として、JAEA 神原氏らの協力により、ラジアルコリメータ「NOVARC」を製作した。

POLANOはコミッショニングを開始したことを先月報告した。真空槽の改修と真空試験を終了し、今月6月はいよいよビームを受けたコミッショニングを開始した。ビームプロファイルの観測や、POLANOに設置してあるPSDの調整を進めている。
