Data Taking 2/March/2013 (MuTrelog entry:1719) MUID1D Trigger Samples @ BBC rate ~ 1MHz HV : Run12 PP Nominal Setting
Contents • Distributions* • (ADC[2]-ADC[0])/ADC[2] • Cluster Size Distribution • PkW Distribution • Hit Samples from • Track Associated • Gap Correlated Hits (Less biased samples) * Plots are summed over all octants. Also MuTrg-FEE installed (non-stereo except for St-2, Gap-2) planes and MuTrg-FEE not installed (stereo + St-2, Gap-2) planes are summed separately. Performance is mostly driven by the timing difference between MuTrg-FEE installed and non-installed planes. See Page 21-27 for individual plane comparison.

Conclusion Best Level-1 Delay • Consistent between 2 (Track Associated & Gap Correlated hits) samples. • The sweet spot differ by 1Bclk between planes with and without MuTrg-FEE planes. • The sweet spot exists between 5 and 6 for MuTrg-FEE installed planes whereas 6 -7 for non-installed planes for South. Level-1 delay=6 seems a good choice to make both planes happy. • There is no common sweet spot for the North case. Given the requirement of better momentum resolution, I prefer Level-1 delay=6 to obtain the best performance in non-stereo planes. • No significant difference in performances between North and South unlike Run11/12. Thanks to Yoshimitsu and Mike Leitch to fix pedestal offset issue.

South : Cluster Size Level-1 Delay=6
South : PkW (Xfit) Level-1 delay=6 The performance difference between planes are relatively minor. Primary characteristics are featured by the existence of MuTrg-FEE.
North : Cluster Size Level-1 Delay=6
North : PkW (Xfit) Level-1 delay=6
