Presentation Transcript

  1. PHENIX Status • PHENIX continues to take physics data • Pretty good weekend 4/29 – 5/1 • Minor DAQ issues addressed • Improvements to PHENIX duty cycle • No major detector issues Average 7.3 DAQ hrs/day 51.2 DAQ hours in the previous week (4/25 – 5/2) days since April 17th J. Lajoie - Machine/Experiment Meeting

  2. LVL2 Filtering Results • Continued the LVL2 filtering effort from the CuCu run • Level-1 triggered events are put through an offline LVL2 filter • Few % of data sample survive LVL2 • LVL2 sample sent to ORNL for fast reconstruction • J/Y Results from ~400nb-1 South North 524 +/- 25 J/Y 592 +/- 27 J/Y J. Lajoie - Machine/Experiment Meeting
