  1. MR/RCS meeting 05/09/06 MR BMとQFXのシャフリング M. Tomizawa BM 96+1台　すべて測定終了 QFX 48台　　すべて測定終了 シャフリングの方針　 (7/26 MR beam commissioning meeting) 50GeVのデータのばらつきの大きなもの どうしでキャンセルさせる 3GeVは確認

  2. s=1.65E-5 s=3.90E-5 DBL/Br ・tolerance s< 4x10-5 (max 3s) ・measurement error 1.7x10-6 @50GeV 1.0x10-5 @3GeV

  3. rms N=96 Bav=15mn=22.41 COD 2.10.09mm @3015A COD 0.890.54mm @200A

  4. :searched to find max cod :assumed to 20m program: Excel+VBAdata: measured and SAD output Qx= 22.41 Used data 50GeV (check 3GeV)

  5. BM shuffling Results ○ magnets serial number max. COD 3.6mm (3015A) max. COD 1.5mm (200A) ○DBL/Br #1,#2,#3,…… max. COD 0.09mm (3015A) max. COD 1.4mm (200A) ○arc-A #1,#96,#4,#93,.. arc-B #2,#95,#5,#92,.. arc-C #3,#94,#6,#91,.. max. COD 0.4mm (3015A) max. COD 1.2mm (200A) #1: minimum of DBL/Br #96: maximum of DBL/Br

  6. By Machida 3015Aの磁場を使い、steering強さのrmsを最小とする。 200のラティス ID: 13788 補正なしでの最大CODが大きいのが気になるが…

  7. By Machida 3015Aの磁場を使い、steering強さのrmsを最小とする配置を 200Aの磁場で確認する。 200のラティス ID: 13788

  8. QFX 48台 DGL/Br s=9.61x10-5 @50GeV (1507A) s=6.93x10-5 @3GeV (100A) Measurement error 3.3x10-5 @50GeV 3.7x10-5 @3GeV
