B1 B4 HES meeting 08/05/09 TUL vs NTuple Grouping ■ Condition ・ In LNS Exp. , We got TUL Grouping Output ( Grouping 1~8 ). So, we can compare TUL and NTuple Grouping. ・ NTuple Grouping EFF. ( TUL Counts / NTuple Counts ) D.C ( 2Layer ) F1 Beam F4
HES meeting 08/05/09 TUL vs NTuple Grouping ■ Event distribution at Hodo Scope and D.C. ● Distribution @ Ehodo ・ 相対的に中心はだいたい合っている。 ・ Grouping の結果とも Consistent. ● Distribution @ D.C. ・ 相対的にD.C.Backward がかなり右に ずれてしまっている。 ・ Backward に Offsetをつけて、調整。.

HES meeting 08/05/09 Timing Resolution Study ■ Procedure • Trigger Counter 、Ehodo、の全ての組み合わせに対して • Slewing Correction を施す。 • ( Slewing Correction は、二次関数を用いて行った。 ) • 誤差の伝播公式を用いて、それぞれのカウンターの時間分解能を • 求める。 Slewing Correction ・ BINを分割しY 軸にProjectionする。 ・ Fitting の対象には、Entry 数が、 分割した際に平均以上ある点のみ。 ・ Fitting には二次関数の逆数を使用。 y = [ 0 ] * ( x – [ 1 ] )-2 + [ 3 ]
