  1. AGS Status and PlansRHIC Spin Collaboration Meeting2/4/11

  2. 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

  3. But not at RHIC Injection • Single measurement at RHIC injection • Blue (sweep, fixed) = (51.4 +/- 1.7, 52.7 +/- 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?
