RUN 11 RHIC MACHINE/EXPERIMENTS MEETING
19 Apr 2011
Agenda: • Wrap-up of 250 GeV pp run• Goals for √s = 18 GeV/n Au-Au run
RUN 11 RHIC MACHINE/EXPERIMENTS MEETING
DECISIONS• 11/23/2010, APEX: Agreed to new APEX schedule, 12 hour sessions (0800-2400) every other week away from maintenance days.
• 2/25/2011, CNI Polarimeters Normalization: Beginning with physics store 15239, changed CNI Polarimeter analyzing power to agree with jet target polarization measurements …18% lower polarization than before.
• 4/11-15/2011, End 250 GeV pp on18 April, switch to 18 GeV AuAu on after jet target polarization measurement at injection is completed
Decisions (cont’)
3/25/2011: AnDY Collisions (W. Fischer, L. Bland, E. Aschenauer, S. Vigdor):
(1) A. Drees will test the sequence developed to address both orbit and tune effects of AnDY at the end of a store (or multiple stores if needed). (2) When the proper functioning of the sequence is demonstrated we will go back to a 1.05e11/bunch threshold, and increase every store by another 0.05e11/bunch until we reach a 10-20% luminosity impact on STAR and PHENIX. In the event the prescribed bunch intensity is not reached during the store then AnDY should be steered into collision during the last 30 minutes of the store. (3) When the tune scan on the ramp finishes (~2 more tune to test), we will increase the store length to 10h or more, (with PHENIX/STAR concurrence), with this AnDY will have more time available after turning on.
Run 11 Plan based on PAC recommendation/ALD Guidance and 28.3 weeks cryo operation4/19/10 update
• 3 Jan, Begin cool-down to 4.5K • 8 Jan, Cool-down to 4.5K complete in both rings, preliminary setup begins• ~11 Jan, 2 ⅟2 weeks beam setup for √s = 500 GeV pp in RHIC begins.• 15 Jan, power supply work/DX training complete• 17 Jan, first successful ramp• 19 Jan, 1st maint day• 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)• 16 Feb, AGS Jump Quads in routine operation for RHIC injection• 24 Feb, 9 MHz cavity in routine operation • 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• 28 March – 1 April, PAC 2011• 15 April Continuing Resolution Ends, guidance to follow• 18 Apr, end 9.4 week physics run at √s = 500 GeV pp run• 18 Apr jet target polarization measurement at injection (<5%) – STILL NO BUDGET GUIDANCE
• 19 Apr, short maintenance followed by setup for √s = 18 GeV AuAu• 25 Apr, begin ~1 week physics run (√s = 18 AuAu)• 2 May, end 1 week physics run at √s = 18 GeV• 2 May, begin 1 week setup for √s = 200 AuAu• 9 May, begin 1 week Ramp-up with 8 hr/night beam to experiments• 16 May, begin ?? week physics run at (√s = 200 GeV/n AuAu)• 4 Jul, completed 26 weeks cryo operations (7 weeks 200 GeV AuAu to this point)
What’s missing :• Uranium test/physics run• Low energy test run• cryo warm-up
