  1. AGS Polarized Proton StatusJanuary 25, 2011Vincent Schoefer

  2. Current performance • 65% polarization with 1.4e11 intensity • Emittances ~18 both planes at AGS flattop (jump quads off) • This is still large horizontally, even coming out the Booster

  3. Tune jump quads • Calculation of jump times: Leif • Gauss clock calibration scan: Leif • Measurement of vertical intrinsic timing: Vincent • Effect on emittance (blowup and scraping) • Coherence length and emittance blowup: Mei • Closed orbit deviations from tune jump quads: Woody • Horizontal scraping on J10 at AGS flattop: Vincent • Momentum scraping at transition: Leif, Vincent • What are the ‘best yet’ times?

  4. Optics • Optics measurement and correction • High injection tune: Vincent • Survey results: Vincent • ORM: Vincent • Harmonic response: Leif • AGS model calibration: Nick, Francois • BtA model calibration: Nick, Keith • Vertical BPM offsets at 9 • via orbit steerer drive term: Woody • via harmonic amplitude response to tune: Leif
