RHIC Run 6 - For Discussion

Plan A (present plan): • 5 Jun: end 200 GeV run, begin 22 GeV test run• 6 Jun: end 22 GeV test run, begin 62 GeV run• 20 Jun: end 62 GeV run, begin 500 GeV development• 26 Jun: end RHIC operations with beam• Plan B (proposed): • 5 Jun: end 200 GeV run, begin 22 GeV test run• 6 Jun: end 22 GeV test run, begin 500 GeV development• 12 Jun: end 500 GeV development, begin 62 GeV run • 26 Jun: end RHIC operations with beam

RHIC Run 6 - For Discussion

A short history (from my Tuesday meeting notes): Date 62 GeV Start Date through 4/18 5/28 (with usual caveats)

4/25 6/1 (added 4 days to schedule as a result of unscheduled shutdown - flag the we needed to "revisit the schedule")

5/2 6/6 (added another 4 days to the schedule, maxing out possible calendar days for RHIC Run 6 and scheduled the 22 GeV test run before 62 GeV run - raised issue that we should consider moving the 62 GeV run to the end to minimize the possible negative impact of the Accelerator Conference on the 500 GeV development run)

The 14.5 week pp “physics” plan, Run6

s = 200 GeV/c (1st 11 weeks)

s = 62.4 GeV/c (next 2 weeks)

– 2 weeks physics• STAR Transverse• PHENIX Transverse• BRAHMS Transverse

s = 500 GeV/c (last 1 week)

– Machine Development

• 0.5 week contingency, use to be determined

RHIC Run 6 Original Plan• 1 Feb – Begin cool-down• 8 Mar –Physics Mode for machine and experiments (5 weeks into

run)• 8 Mar – begin 11 weeks of s=200 GeV pp• 24 May – end 11 weeks s=200 GeV pp• 24 May begin setup s=62 GeV pp• 7 Jun – end 2 week s=62 GeV pp• 7 Jun – begin 1 week s=500 GeV pp development• 14-18 Jun – Contingency (end 14.5 weeks “Physics”)• 18 Jun – begin cyro warm-up • 21 Jun – RHIC Cryo warm-up complete, end 20.0 weeks of cryo

operation

20

RHIC Run 7 – first look at possible run plan

• PHENIX– Long Au-Au run at s=200 GeV/n– pp development, especially for s=500 GeV

• STAR– d-Au at s=200 GeV/n– pp development
