  1. Run 9 polarized proton Log • 9 Jan begin 45 degree cool down from room temp (3 MW-NEW) • 2 Feb, Cool-down to 4.5 degrees begins • 5 Feb, Blue ring cold but still stabilizing • 7 Feb, beam injected into Blue ring, • 8 Feb, Yellow cold but still stabilizing • 9 Feb, 2 week “Setup” mode begins(0.5 weeks early) • 13 Feb, Beam injected into Yellow ring • 14 Feb, STAR magnet on, ramp development begins • 17 Feb Nov, First collisions @ s = 500 GeV (2.3 weeks into run – a record!) • 24 Feb, “Ramp-Up” mode begins, overnight stores for experiments • 6 Mar, Machine in “Physics” mode, integrated lumi begins • 16 Mar, Spin rotator ramps established, longitudal polarization available • 17 Mar Experiments in Physics mode • 13 April (1200), end s = 500 GeV physics (3.9 weeks), begin last s = 500 GeV beam development followed by new low level RF setup • 15 April (0800), Maintenance and s = 200 GeV ramp setup • 15 April (2100), begin setup with beam for s = 200 GeV • 20 April (2341), s = 200 GeV physics begins (8 days early) with further ramp-up • 21 April (1802), PHENIX physics begins • 23 April , STAR physics begins • 29 June (0800), end s = 200 GeV main physics run (10 weeks) • 29 June (0800), setup for pp2pp at STAR run begins, PHENIX remains on • 30 June (0009), pp2pp Physics on but beam tune-up continues • 4 July (1000), pp2pp ends (0.6 weeks), beam studies at s = 500 GeV begin • 6 July (1000), RHIC beam studies end, cryo warmup begins • 8 Jul, cryo warm-up ~complete, 22.3 weeks cryo operation

  2. Run 9 s = 500 GeV Physics Goals • PHENIX ~75 pb-1 delivered, ~25 pb-1 recorded ~50% polarization, quality factor is P2L = 19 pb-1 delivered • STAR ~ 30 pb-1 delivered, ~ 10 pb-1 recorded ~ 50% polarization, quality factor is P2L = 7.5 pb-1 delivered

  3. ~Phenix goal (25 pb-1 recorded) With 50% longitudal polarization P2L QF ~Star goal (10 pb-1 sampled) with 50% longitudal polarization P2L QF Experiments start physics with longitudal polarization Blue average polarization (preliminary Jet target) = 33.1 ± 0.8 % Yellow average polarization (preliminary Jet target) = 35.1 ± 0.9 %
