  1. PHENIX Status Stefan Bathe, Time Meeting, June 1, 2010

  2. 7.7 GeV Close-Out BBCLL1(>1 tubes) 1.5 M minimum bias events recorded @ 7.7 GeV Stefan Bathe

  3. Minimum Bias Event Rate run index (= store) Average rate of 1.8 Hz in 2nd half of 7.7 GeV run Stefan Bathe

  4. Muon Trigger Commissioning • No collisions in PHENIX @ 11.5 GeV • Commissioning new muon detectors with cosmic rays • Crucial for next year’s W physics program • 2-person watch shifts + experts Stefan Bathe

  5. Fire Alarm Last Night • At 1:00am last night smoke alarm shut off experiment • Originated from rack WCB2 rack (holds MuID Blue Logic electronics) • WCB2 was shut off first by safety system • Smoke apparently leaked out of rack enough to trigger VESDA HSSD system, which shut off entire experiment • Took access, no visible burning, but noticeable smoke odor • Turned circuit breakers back on • Re-established flammable gas flow • Currently switching on racks (except for WCB2), front end electronics • Expect to be back up tomorrow morning • Need 60-90 minute access to evaluate course of alarm Stefan Bathe
