  1. SksMinusstatus20 HB meeting 2009/2/16 白鳥昂太郎

  2. Contents • Detector • Number of ch, module, crate and cable • Trigger timing

  3. SksMinus関連

  4. SksMinus readout channels • DC : total 2320ch (T) • SDC1 (xxuuvv) : 80 ch×6 = 480 ch (MHTDC) • SDC2 (xxuu) : 112 ch×4 = 448 ch (MHTDC) • SDC3 (xxuuvv) : 108 ch×2 + 120 ch×4 = 696 ch (Dr.T) • SDC4 (xxuuvv) : 108 ch×2 + 120 ch×4 = 696 ch (Dr.T) • Timing counter : total 67 ch (A&T, BNC cable : 134) • STOF : 32 segment = 64 A&T (TKO ADC, HRTDC) • BH2 : 1 segment = 2 A&T (TKO ADC, HRTDC) • BP : 1 segment = 1 A&T (TKO ADC, HRTDC) • Veto counter : total 104 ch (A&T, BNC cable : 208) • SMF : 32 segments : 32 A&T (TKO ADC, HRTDC) • SP0 : 10×6 + 6×2: 72 A&T (TKO ADC, HRTDC) • AC : total 12 ch (A&T, BNC cable : 24) • SAC1 : 5 ch = 5 A&T (TKO ADC, HRTDC) • SAC2 : 2 ch = 2 A&T (TKO ADC, HRTDC) • SFV : 1 ch = 1 A&T (TKO ADC, HRTDC) • BAC : 2 ch×2 = 4 A&T (TKO ADC, HRTDC) • MHTDC • = 128 ch×8 • Dr.T = 32 ch TDC×44 • TKO ADC • = 32 ch ADC×6 • HR TDC • = 16 ch TDC×12

  5. Readout channels

  6. Area KEK-VME 9U x 2 GPIO x 2 GPIO-RM x 2 ⇒SksMinusでも同じ KEK-VME 6U x 1 VME-SBC x 1 VME-SMP x 1-4 TKO Box x 1-4 TKO-RM x 1 RPV130 x 1-2 ⇒ MHTDC + 2台

  7. Counting room *SKS KEK-VME 6U x 1 VME-SBC x 1 VME-SMP x 3-4 TKO-Box x 3-4 TKO-RM x 1 RPV130 x 2 RPV100 x 3-4 *SksMinus KEK-VME 6U x 1 VME-SBC x 1 VME-SMP x 3-4 TKO-Box x 3-4 TKO-RM x 1 RPV130 x 2 RPV100 x 3-4 ⇒SMPとTKO-Boxが増加

  8. Cables

  9. ケーブルの組み合わせ (“新規”ケーブルはrequest for support に申請中）

  10. HV cables

  11. To do • Trigger timing estimate • Delay cable ? • Counting room arrange • Meeting to SKS users • Cables are prepared by KEK. ⇒How many additional cables ?

  12. Hyperball-J関連

  13. Hyperball-J readout channels • Ge : Total 32 ch (A&T&R) • 973U & TFA×32 • CFD (4 ch)×8 • AD413a (4 ch)×8 • 3377 MHTDC (32 ch)×2 (TDC & Reset) • PWO: Total 246 ch (T) • VME discri (16 ch)×16 • 3377 MHTDC (32 ch)×8 • 16 TKO TDC (Dr.T)×16 • (16 ch QDC (4300B)×16 ?) Which ?

  14. Hyperball-J module number ⇒ Hyperball2と同規模: 4つ

  15. Hyperball-J用回路スペース Cable長 約15 m, しかし、スペース足らんと思わないか！？

  16. Cables

  17. To do • All module check • Broken module repair ⇒To make the Hyperball module list + Ge detector performance table/history ⇒Data base • Hyperball2 disassembly • Modules, lemo cables, NIM-BIN • Ge energy resolution and time resolution check by a long cable (93W v.s. 50W) • Hyperball2 : 10m cable⇒往復させて20 mでcheck • PWO HV module • Hyperball2 : BGO 150 ch ⇒ 2 HV module (70% of current limit) • Hyperball-J : PWO 246 ch ⇒ 3~4 HV module

  18. Trigger timing まだ、途中。。。

  19. 検出器への到達時間の比較

  20. Timing Chart (SKSPlusの場合) Dr.T-II delay 大雑把にトリガー生成 delay time を約200ns (Beamtrigger, K/Piトリガー生成時間はMin. 130~150ns あたり)
