Experiments luminosity goals for Run 8, 100 x 100 GeV pp

– PHENIX• Delivered luminosity = 140 nb-1

• Recorded luminosity = 35 nb-1

– Longitudal Polarization goal: 26 nb-1

– Transverse polarization luminosity goal: 9 nb-1

• Assumed efficiencies: 48% vertex, 64% up, 82% live 25% overall• Assumed polarization: 65%• Approximate physics weeks: 12

– STAR• Delivered luminosity = 90 nb-1

– Longitudal polarization goal: 60 nb-1

– Transverse polarization luminosity goal: 30 nb-1

• Slow detector sampled luminosity (Transverse and Longitudal) = 30 nb-1

• Assumed efficiencies: 50% uptime, 65% live 33% overall• Assumed polarization: 65%• Approximate physics weeks: 12

• pp2pp: 3 days of dedicated running • Goals: 20M elastics, 300K double pomeron exchange events

An issue: In 2006 it took 6 weeks of physics running to get from ~45% polarization to ~60% polarization, above goals assume 65% from physics day 1

(last update 10/23/07)Experiments luminosity goals for Run 8 100 x 100 GeV/n d-Au

– PHENIX• Delivered luminosity = 230 nb-1

• Recorded luminosity = 58 nb-1

• Assumed efficiencies: 48% vertex, 53% live 25% overall• Approximate weeks: 10

– STAR• Delivered luminosity = 120 nb-1

• Fast Detector sampled luminosity = 60 nb-1

• Slow Detector sampled luminosity = 30 nb-1

• Fast detector overall sampling efficiency = 50%• Approximate weeks: 10

– Monopole Proposal – Detector Tests• Once ~ 20:1 signal to background is achieved in building 902, move to 10:00 IR,

reestablish good signal to background and then request collisions
