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（2023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2023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。
2021年度より、実験課題審査分科が６分科に再編され、PFの全てのビームライン（低速陽電子実験施設のビームラインを含む）は審査分科に対応した６のビームライン群に分類して運用されています。ビームライン群について、詳しくはこちらのページを参照してください。
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）
