  1. MuTRG for Run12 RIKEN/RBRC Itaru Nakagawa

  2. Run12 Schedule • 14 Cryoweeks -> Mid Jan. ~ End of April 200 GeVpp (2+3 weeks) + 500 GeVpp (1+6 weeks)? 500 GeVpp (2+5 weeks) + 200 GeV Au-Au (2+3 weeks)? Else ?

  3. Travel Schedule Joe Katsuro Itaru? Itaru Itaru Yoshimitsu Yoshimitsu, Sanghwa, Hide, Kentaro Kentaro Cramp Cosmic Cosmic Run w/ SG1 Trigger SG1 SG1+RPC1 Timing Possible speed up by 20ns Timing Collision

  4. Shift

  5. Cosmic Data Taking pre-Run12 • Purpose • SG1 trigger efficiency study for high momentum m • Real high momentum track sample collections • Cross Talk Effect before/after recapacitation • Position/Momentum Resolution • SG1 Startup for Cosmic (Jan. 3 ~) Katsuro, Joe • LL1 Width=7, low threshold~20mV, LOGIC=OR • Run Stability Monitor • RPC Commissioning (Jan.3 ~ mid Jan.) • RPC1 Integration (mid Jan.) Itaru, Joe? • Timing Tune with SG1 Trigger • Need to Cover 24 hour shift by FWD group • May need to cover 3rd week of Jan. Who can travel?

  6. New Physics with Forward VTX Detector Installed for Run12 Invariant Mass Distribution of m+m- Drell Yan ϒ-states J/Ψ charm beauty • 4 GeV < M < 10 GeV Background (bottom,Charm) Separation using FVTX 1.2<y<2.4 Fwd VTX

  7. SG1 Trigger New SG3/SG5 Trigger for Heavy Flavors MuID SG3/5 SG1 W MuID Trigger

  8. Consideration Trigger Map • Develop SG3/SG5 Trigger Map • John Lajoie • LANL postdoc (Jin) • From our group? • Operating Condition • Optimized for SG1 at 500GeV • Unique optimization for SG3/5 at 200 GeV • SG3/SG5 Rates • Need prescale? • Turn on Curve Essential semi-online analysis -> Sanghwa

  9. Special Run • Low B-field? • Re-cap Effect (Yoshimitsu, Kentaro) • 1x1 (3?) bunch collision • Analysis Software ready? • Hit Rates vs. Beam Clock • Zero suppression off data taking • Peak Strip ADC vs. Negative shoot • BBC Rate Dependent Plane Hit Rate/SG1 Rate

  10. Complete GTM Delay Scan • GTM delay needs to be optimized to get the best SG1 trigger efficiency

  11. Timing spectra of MuTrig Efficiency ~ 0.7 /station 0.7 Efficiency 2BCLK width integration 0.6 GTM delay Scan GTM delay [ns] Analysis Software Needs to be Availablein Beginning of Jan. (Sanghwa) Efficiency ~ 0.9 /station 0.88 Efficiency 0.8 3BCLK width integration GTM delay [ns] GTM delay [ns]

  12. GTM Delay Map OR AND2 Offline Analysis By Yoshinori Fukao

  13. Things to be addressed during commissioning • GTM Delay Scan Map • Why only North Station-2 Timing is slower than other octants? • Low Gain? -> May be resolved by Ar enriched gas mixture? • ADTX failure mode study by test pulse • Address why North SG1 Rates is factor of 3 higher than that of South? • Noisy channel check. High trigger rates in particular section? • Octant by Octant SG1 rate (Do we have software?)

  14. Bad ADTX Boards 2011 May 21, Au-Au (Elog entry 878) MRG ID.74 (South Oct.3, St.2 HOct.0) Ch.5 [S, St2, Oct3, Chs4, Brd1] 2011 May 18, Au-Au (Elog entry 877) MRG ID.125 (North Oct.6 St.3 HOct.2) Ch.3 [N, St3, Oct6, Chs2, Brd2] MRG ID.72 (South Oct.1 St.2 HOct.0) Ch.5 [S, St2, Oct1, Chs4, Brd1] Before Run11 MRG ID.115 (North Oct.4 St.3 HOct.1) Ch.5 [N, St3, Oct4, Chs7, Brd2] MRG ID.123 (North Oct.4 St.3 HOct.2) Ch.1 [N, St3, Oct4, Chs1, Brd1] <- accessible Errors OK! Fiber connection between ADTX <-> MRG was inspected. No anomaly was found. Frequent error may be reproduced by test pattern. (To be tested)

  15. Backup
