AGS Status and Plans RHIC Spin Collaboration Meeting 2/4/11

Polarization profiles Measured polarization profiles in the AGS – Horizontal profile steeper than in previous runs – Vertical profile is flat Completed intensity scan with J10 scrape – Consistent with a horizontal profile – Steeper dependence than any Booster scraping method

But not at RHIC Injection Single measurement at RHIC injection – Blue (sweep, fixed) = (51.4 +/- 1.7, /- 1.3) – Yellow (sweep, fixed) = (48.2 +/- 1.5, 52.1 /- 1.2) Questions: Where does the steeper profile come from? Where does it go between AGS and RHIC? How is it affected by the jump quads?
