  1. AGS Status and PlansRHIC Spin Collaboration Meeting2/18/11

  2. Update • Jump quads have been on for every RHIC fill since Wednesday evening (first physics fill Thursday evening, fill no. 15190) • Benefit in the AGS is clear, will have to assess effect in RHIC over more stores. • Horizontal profile is much improved • Polarization versus intensity dependence also reduced

  3. Plans • Measure horizontal profile with jump quad time shift (should shut off resonance jumping) • Does the horizontal target measurement agree with average of horizontal profile? • Do a few of the jumps dominate the effect? • Turn off groups of pulses (the last few are expected to be the most beneficial)
