d-Au : 5 weeks, 4 energies• “Five to seven weeks of running to perform a small

system beam energy scan (PAC) »

Our optimized choice for 5 weeks: • 20 GeV 1.5 week 9M (BUP: 7M)• 39 GeV 1.5 week 110M (110M)• 62 GeV 1. week 160M (230M)• 200 GeV 1. week 1.6 B (2.4B)Allowing a complete energy scan in the same detectionconditions, and keeping BUP and PAC goals of measuring the excitation function of 2-particle correlations and V2, and possibly - the first BES measurement of V3 in small systems at RHIC.19/01/2016 PHENIX RC RHIC machine-experiment 12
