Summary of 200 GeV CuCu Minimum Bias Event Totals and Trigger Performance

This report provides a comprehensive summary of the 200 GeV CuCu minimum bias event totals as of March 7, 2005. The final tally for minimum bias events reached 64.47 million, falling short of the target of 80 million, with an average of approximately 1.24 million events per day over 52 operational days. For the High Tower (HT18) trigger, a total of 4.53 million events were recorded against a goal of 6.5 million. The document also outlines data acquisition (DAQ) hours, providing insights into detector efficiency and operational metrics for each trigger configuration.

  1. Final STAR 200 GeV CuCu Min bias Narrow Event totals (as of 3/7/05 ) • Final Total: 64.47 Mevts of Min-bias • Goal was 80 Mevts. • Min bias Trigger was operational for 52 days. The “run” average number of mb events per day was thus ~ 1.24 Mevts/day Ave/day ~ 1.24 Mevts

  2. Final 200 GeV CuCu BEMC HT18 Trigger Totals ( 3/7/05) • Final total: 4.53 Mevts • Goal was 6.5 Mevts • HT18 Trigger was operational for 35 days. The “run” average number of mb events per day was thus ~ 129 kevts/day • STAR BUR Goal was to sample ~ 1 to 2 nb-1 with the High Pt Trigger. • 1 nb-1 is equivalent to ~ 4.3 Mevts of this HT trigger. • 6.5 Mevts is ~ 1.5 nb-1 sampled. • If taken at ~ 50% Detector live, requires ~ 3 nb-1 delivered.

  3. Total 200 GeV CuCu DAQ Hours DAQ Hours Total 1/14 to 8 pm 3/6 (52 days) = 336.87 hrs <DAQ hrs/day> ~ 6.48 hrs/day N.B. “DAQ hrs” only count time when production min-bias or High Tower Trigger Configurations are running. DAQ Hrs for 8 am Tuesday Feb 22nd, to 8 am Tuesday Mar. 1st = 57.7 hrs. DAQ Hrs for 8 am Tuesday Mar 1st, to 8 pm Sunday Mar. 6th = 31.6 hrs.

  4.
