ビームタイム配分状況

放射光共同利用実験に申請された課題は、放射光共同利用実験審査委員会(PF-PAC)で審査され、最高5点で評点が付けられます。基準以上の評点(2019年現在は2.5点)の課題は採択とされますが、各期ごとに、採択された課題のうち(原則として)評点の高い課題から順番にビームタイムが配分されます。したがって、課題が採択されたことは必ずしもビームタイム配分を約束するものではありません。
ここでは、ビームライン(群)毎に、評点と2019年度のビームタイム配分状況をまとめました。ビームタイム申請の参考にしてください。


LS (Light Source) 当該ビームラインの光源種別(BM: 偏向電磁石、U: アンジュレーター、SGU: 短周期アンジュレーター、MPW: 多極ウィグラー、VW: 垂直ウィグラー、SP: 低速陽電子)
No. (Number of Proposals) 当該ビームラインの有効課題数
AllocBT (Allocated Beamtime) 当該ビームラインにおいて、配分されたビームタイムの総時間数/要求ビームタイムの総時間数
Cut-off (Cutoff Score) 当該ビームラインにおいて、ビームタイム配分があった課題の最低評点(この評点未満の課題にはビームタイムが配分されなかった)
