1. AGS PP Progress Haixin Huang Time Meeting January, 31, 2012

2. Haixin Huang2 Status AGS setup is stable over past one week. Polarization is around 70% at extraction. The focus of last week was injection polarization measurement with e880 polarimeter. Many thanks to Dave Underwood, Hal Spinka and Steve Gliske who worked on e880 polarimeter after their STAR shifts. Compared to the past, the injection asymmetry (polarization) is higher this year.

The gain vs. last year could be different harmonic correction.
