RUN 11 RHIC MACHINE/EXPERIMENTS MEETING
7 Jun 2011
Agenda:
• √s = 200 GeV AuAu progress• 27 GeV Run (or other)
Run 11 Plan based on PAC recommendation/ALD Guidance and available funds 6/7/10 update
• 3 Jan, Begin cool-down to 4.5K • 8 Jan, Cool-down to 4.5K complete in both rings, preliminary setup begins• 24 Jan, 1 week Ramp-up with 8 hr/night beam to experiments• 11 Feb (machine and ~experiments), begin ~10 week physics run (√s = 500 GeV pp)• 7 Mar, cryo troubles, extended maintenance, 0900 hrs till 2000 hrs 14 Mar – lost 7.5 days• 17 Mar, power distribution problem, extended maintenance, 1930 hrs till 0315 hrs 20 Mar –
lost 2.3 days• 18 Apr, end 9.4 week physics run at √s = 500 GeV• 18 Apr jet target polarization measurement at injection (<5%) • 19 Apr, short maintenance followed by setup for √s = 18 GeV AuAu• 23 Apr, begin ~1 week physics run (√s = 19.6 AuAu)• 2 May 08:00, end 1.3 week physics run at √s = 19.6 GeV• 2 May, begin setup for √s = 200 AuAu• 5 May, begin 2 day Ramp-up with 8 hr/night beam to experiments• 6 May 11:37, begin ~8 week physics run at (√s = 200 GeV/n AuAu)
• 7 Jun- TODAY• 29 June, end 7.7 wk AuAu physics run at √s = 200 GeV/n , begin warm-up• 30 June, cryo warm-up ~ complete, end 25.4 weeks cryo operation
What’s missing :• Run into July?• 27 GeV AuAu; Uranium test/physics run• Low energy test run
PREP TIME REQ’D, NEED DECISION SOON!
