Outline of Annual Research Achievements

2022 年度は、TDR (Technical Design　Report) 策定に向けて、日本グループが FoCal検出器の試作器を製作し、その性能評価実験を様々な加速器を用いて行なった。

まず日本グループとグルノーブルLPSC と共同でFoCal-E pad 試作器を製作した。その後、本試作器のテストビーム実験を、CERN PS 加速器のテストビームラインを用いて実施した。その結果、電子ビーム 1-2 GeV/c でおおむね所定性能を有していることを確認するとともに、4GeV/c 以上からTOT による読出しを必要とすることが分かった。続いてCERN SPS（Super Proton Synchrotron）が供する高エネルギー・ハドロンビーム及び電子ビームを使って実験を実施した。40-300 GeV/c 電子ビームに対するエネルギー分解能や、20-350GeV/c ハドロンビームを使った最小電離粒子 MIP (Minimum Ionizing Paricle) に対する応答の評価した。その結果、所定の性能を有していることが分かった。3月には、理研 RANS を利用して、シリコンパッドセンサの２回目の中性子照射試験もおこなった。さらに　2 月では、東北大学　ELPH においてテストビーム実験を行った。FoCal-E PAD のバイアス電圧依存性・温度依存性の測定、およびn-type シリコンセンサーの中性子照射による影響を調べた。その結果、温度によらずほぼ一定の位置にMIP ピークが観測され、55°C 程度の環境下までなら、温度によらず同性能を持つことが分かった。これらの結果は、LHCC 国際委員会に提出する TDR に反映される。2023年1月、中條は FoCal プロジェクトの共同代表を務めることとなった。

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

試作器を製作し、その性能評価実験を行い、所定の性能を有していることが確かめられた。これは建設に向けた大きな進展である。さらに本代表は、 FoCal プロジェクトの共同代表を務め、本国際プロジェクトをリードしている。国内外の発表においても、本グループが主導しており、国際ワークショップも３月に主催した。

Strategy for Future Research Activity

2022年に行なった様々な実験結果を評価し、Technical Design Report (TDR) にまとめ、LHCC 国際委員会に提出し、2023年度末における承認を目指す。同時に、得られた結果を投稿論文としてまとめる。FoCal 日本グループのさらなる拡大を進め、日本が主導する国際プロジェクトとしての地位なものにする。その上で、最終試作器の製作、マスプロダクションの準備を進める。
