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)

• 17 May- TODAY• 29 June, end 7.7 week 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?• Uranium test/physics run• Low energy test run only 2 days!

√S = 200 GeV/n AuAu luminosity goals (to be updated)
