  1. PHENIX Status Time Meeting, 2/9/2010 Stefan Bathe Stefan Bathe for PHENIX, Time Meeting

  2. Sampled Integrated Luminosity 0.55 / 1.4 (nb^-1) = 39% of goal (for sampled int. lumi.) 30/70 (days) = 43 % of time Stefan Bathe for PHENIX, Time Meeting

  3. DAQ Performance  if rate had been > 5 kHz at all times: could have recorded 4.49 billion events or 0.66 nb^-1 # events Int. lumi. in nb^-1 x10^6 Delivered beam ± 30 cm (PHENIX on) Taking min bias data: with |z| < 30 cm if DAQ rate < 5 kHz with |z| < 20 cm if DAQ rate > 5 kHz Recorded beam ± 30 cm (PHENIX on): 77 % Delivered beam ± 20 cm (PHENIX on) Recorded beam ± 20 cm (PHENIX on): 86 % HBD acceptance: ± 20 cm Stefan Bathe for PHENIX, Time Meeting

  4. Beam z Profile Now: 50-60 % Run-07: 50 % Projected Run-10: 65 % Begin fill: 59 % After 3 h: 50 % Stefan Bathe for PHENIX, Time Meeting

  5. Plan for Maintenance Day • MuTrFEM and HV fixes • Change MuTrigTLD's on South Station-1 • Fix West Carriage light • HBD rack work • RPC work in North Tunnel Stefan Bathe for PHENIX, Time Meeting
