Possible Run 10 plan based on 25 Nov Revised Plan
• Run10, 25 cryo-weeks (my guesses after Jan 12)
– Dec. 1, Begin cooldown to 4.5K – Dec. 4, Cooldown to 4.5K complete in both rings!– Dec. 5, beam setup in RHIC begins.– Dec 16, 20 hr unplanned Maintenance day– Dec 20 (AM)-21(PM), blizzard 09 shut us down– Dec. 27, RHIC Setup complete, begin Ramp Up for Physics (was 14 Dec, late)– Dec 31 (midnight-store 11340), Machine (and PHENIX?) Physics declared s=200 GeV/n Au-Au– Jan 2 (midnight) STAR in Physics Mode– Jan 8 (0600) PHENIX in Physics Mode– Jan 12, Rebucketing not yet routine– Mar. 11, End 10 week s = 200 GeV/n Run, begin s = 62.4 GeV/n setup– Mar. 13, Begin 4 week s = 62.4 GeV/n run– Apr. 10, End 4 week s = 62.4 GeV/n Run, begin s = 39 GeV/n setup– Apr. 12, Begin 1.5 week s = 39 GeV/n run– Apr. 23, End 1.5 week s = 39 GeV/n Run, begin s = 7.7 GeV/n setup– Apr. 25, Begin 4 week s = 7.7 GeV/n run– May 20, End 4 week s = 7.7 GeV/n Run, begin s = 5.0 GeV/n setup– May 23, End 4 week s = 7.7 GeV/n Run, begin s = 5.0 GeV/n setup – May 25, begin 0.5 week beam studies at s = 5 GeV/n and ~ 0.67 - – 25 CRYO WEEK– This is it unless we have $’s to run longer – revisit in March– May 29, end 0.5 week studies– May 31, begin s = 11.5 GeV/n for STAR– Jun 15, end 2 week s = 11.5 GeV/n run– Jun 15 , Begin Cryo Warm-up– Jun 16, Warm-up complete, Run 10 ends – 28.2 CRYO WEEKS
