AGS Status & Plans: RHIC Spin Collaboration Meeting 4/8/11

Updates on AGS status include retrying jump quad pulse effects, effectiveness of timing shifts, damper impact, and future plans to study polarization profile, optimize optics, and explore vertical scraping at AGS extraction.

  1. AGS Status and PlansRHIC Spin Collaboration Meeting4/8/11

  2. AGS Status • Inconsistent results regarding the effect of the last jump quad pulse, will retry with horizontal target. • Timing shifts of the other pulses appear to be effective in turning off the resonance jumping • Ramp polarization measurement • Damper appears to help reduce vertical tails (core emittance ~unchanged) and improve AtR transfer efficiency

  3. Plans • Quantify effect of jump quads on polarization profile (once effect of last pulse is established) • Finish studies of optics (minimize effects of jqs on emittance) • Is there a possibility of vertical scraping at AGS extraction using coupling and the J10 dump?
