SksMinus Detector Readout and Trigger Timing Discussion - Meeting Notes (2009/2/16)

This document outlines the key points discussed in the meeting regarding the SksMinus detector's readout channels and trigger timing. It details the channel configuration for multiple modules, including MHTDC, TKO.ADC, and HRTDC, and their respective channel counts. Additionally, it addresses the preparation and arrangement of necessary cables, the estimation of trigger timing delays, and the overview of readout setups for Hyperball-J modules. The document aims to ensure effective coordination among SKS users and the proper assembly of required components.

  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)
