1 MuTRG for Run12 RIKEN/RBRC Itaru Nakagawa 1

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

3 Travel Schedule Month Dec.Jan.Feb. Week 1234123412 BNL Tasks Itaru Katsuro Yoshimitsu Kentaro Cramp SG1 Cosmic Run w/ SG1 Trigger Cosmic Timing Possible speed up by 20ns Itaru? Yoshimitsu, Sanghwa, Hide, Kentaro Itaru SG1+RPC1 Timing Joe Collision 3

4 Shift 4

5 Cosmic Data Taking pre-Run12 Purpose – SG1 trigger efficiency study for high momentum  – 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 3 rd week of Jan. Who can travel? 5

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

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 8

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 9

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

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

12 GTM Delay Map LOGIC ThresholdLL1 Width [mV]23 OR 20 402515 603538 AND2 (St1) 40 60 All AND 60 100 Offline Analysis By Yoshinori Fukao OR AND2 12

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?) 13

14 Errors OK! 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] Fiber connection between ADTX MRG was inspected. No anomaly was found. Frequent error may be reproduced by test pattern. (To be tested) <- accessible 14
