V physics (3. 9 weeks), begin last s = 500 Ge. V beam development followed by new low level RF setup 15 April (0800), Maintenance and s = 200 Ge. V ramp setup 15 April (2100), begin setup with beam for s = 200 Ge. V 20 April (2341), s = 200 Ge. V physics begins (8 days early) with further ramp-up 21 April (1802), PHENIX physics begins 23 April , STAR physics begins 29 June (0800), pp 2 pp at STAR run begins, PHENIX on • 3 -6 Jul (when pp 2 pp and RHIC studies finished), Run 9 ends (10. 6+ weeks s = 200 Ge. V physics) , • 6 Jul, cryo warm-up begins • 8 Jul, cryo warm-up ~complete, 22. 3 weeks cryo operation

Run 9 s = 200 Ge. V Physics Goals • PHENIX (revised 5/19/09) – 65 pb-1 delivered, ~25 pb-1 recorded – 60% polarization, quality factor is P 4 L – FOM = 65 x (0. 60)4 = 8. 4 pb-1 delivered • STAR – 100 pb-1 delivered, ~50 pb-1 recorded – ~60% polarization, quality factor is P 4 L – FOM = 100 x (0. 6)4 = 13 pb-1 delivered

~2. 3 pb-1/day ~1. 1 pb-1/day

Blue Jet weighted average = 55. 4 ± 0. 5 Yellow Jet weighted average = 54. 9 ± 0. 5
