  1. RCS BM shuffling 平成１７年９月２７日 發知　英明

  2. BL data of RCS BM 0.181 to 3 GeV BLmax : 5x10-4 BLac : 4.4x10-5 BLdc BLmin : 1x10-3 DBLx=0/<BL>x=0 : ±8E-4

  3. DK0 0.181 to 3GeV DK0 BM No. DK0 : ±0.2 mrad

  4. COD “Arrangement according to the production number” COD at (6.68, 6.27) Max. COD : ~±7 mm

  5. Shuffling for BMs [1] [2] [3] [4] [5] [6] Dy～p [7] [9] [11] [8] [10] [12] yy yx BM No. DBL/<BL> DK0 Allocation

  6. COD COD at (6.68, 6.27) before shuffling after shuffling dx (m) s (m) Max. COD :6.7 mm→2.3 mm

  7. COD correction with STMHs COD at (6.68, 6.27) Max COD : 6.7 mm → 0.5 mm 2.3 mm → 0.5 mm dx (m) BPM’s reso. assumed : 0.2 mm (rms) s (m) Required K0 for STMHs 400 G STMH K0 S |K0|/N : 6.3e-5 →4.6e-5 STMH No.

  8. Tune dependence – COD - Tune space surveyed : Qx,Qy = 6.08 ~ 6.92 (0.04 step) Qx=6.08~6.92 (Qy=6.28 fixed) before shuffling dx (m) after shuffling s (m) Max. COD < 3mm for Qx=6.24~6.88 Max. COD (m) nominal tune Qx (Qy=6.28 fixed)

  9. Tune dependence – COD corr. - Tune space surveyed : Qx,Qy = 6.08 ~ 6.92 (0.04 step) Qx=6.08~6.92 (Qy=6.28 fixed) BMP’s resolution assumed : 0.2 mm(rms) dx (m) (COD)rms ~0.2mm s (m) STMH K0 STMH No.

  10. Source of COD • BM BLのばらつき　~3 mm • BM 入口出口の非対称性　~0.7 mm • EXT SEPTUMからの漏れ磁場　~2 mm • ~~~~~~~~~~~~~~~~~~~~~ • INJ SEPTUMからの漏れ磁場 評価中（Saha） • BM,QM Alignment errors (0.25mm, 0.5mrad)
