4. W Trigger Rejection Power

5. W trigger status Compare above trigger rates in three different periods.

7. Rejection Power Summary • W triggers were formed by 5 different trigger mixes with the combination of SG1, RPC1&3, MUID1D • Rejection Power was sufficient to be <2kHz for the total of 5 triggers. • Compared to Run12, rejection power is stronger due to MUID1D in the trigger mix. SG1 and RPC were operated loose condition.

10. Fake Hit Rates History North South St-1 St-1 Hot! (threshold failure) St-2 St-2 Low efficiency MuTr HV problem, etc St-3 St-3 Overall stable. Shallow slop may come from luminosity increase.

11. Fake Hit Rates vs. BBC Rate North Station-2 Octant Average Hit Rates Oct-1 Oct-2 Oct-3 Oct-4 Oct-5 Oct-6 Oct-7 Oct-8 Hot! Too low efficiency? Fake Hit Rates are sampled from abort gap, however it is not free from beam effect presumably due to long time constant of MuTr signal. So Fake rates are linearly proportional to BBC rate. Thus data/(linear fit) should distribute around 1.

12. North Station-2 Data / Linear Fit Distribution <- Fraction of data within 3 sigma (may be tight) of Gaussian distribution. Mostly >90%.

13. Fake Hit Rates vs. BBC Rate North Station-1 Octant Average Hit Rates Oct-1 Oct-2 Oct-3 Oct-4 Oct-5 Oct-6 Oct-7 Oct-8 Octant-1 and Octant-8 shows double band.

14. Fake Rates Close Look The fake rates of oct-1, 8 jumped by about double. Timing is a part by 1.5days. The fake rates of both octants came back to as they used to be at the same time. North Station1 Fake Rates ~ Jun. 3, 10:00 May 19, 19:00 ~ May 18, 2:00 ~ 395432 Before oct-8 jump 395526 after oct-8 jump 395768 after oct-1 jump

15. South Fake Rates Close Look Station-1 Station-2 393578 (May 4, 3:30) ~ 396883 (May 28, 4:50) Sudden rate change is most likely to be caused by hot strip appears and disappears after a while. So the trigger should be OK.

17. LL1 Efficiency (South) Courtesy of Sanghwa’s Stability Monitor Overall, good efficiency except for more frequent efficiency drop in Octant-5 than others (known from Run12).

18. LL1 Efficiency (North) Relatively frequent low efficiency seen in Octant-1 and 5. These tiles are located at same location on the LL1 board (not clear if it is correlated).

31. Summary • Total W trigger rates (trigger mix SG1, RPC1&3, MUID) survived BBC~ 5MHz without prescaling. • All ADTX/MRG remain unmasked except for temporary periods. • LL1 Efficiency Occasional low efficiency observed in South Octant-5, North Octant-1 & 5 though, the luminosity and runtime weighted average turned out to be >95%. • MuTr FEE also remained unmasked. • MuTr HV are survived mostly, except for one channel which is masked in the middle of run. • MuTr acceptance was active except for half octant in North arm.
