RHIC Startup: Recovered from Maintenance Day with first store at 9:00PM. Began with a 6x6 bunch store, with an 87x87 bunch store for physics at 10:40PM.
Using the new dAu81 lattice with beta* of 0.8 in Yellow. The new lattice appears to have a smaller emittance in Yellow than Blue at the beginning of the store.
STAR lost their BBC counters and needed to make an access (circa 5:00AM) to swap a card, so they do not have an estimate of the background rates with the new lattice. Vacuum near STAR is improved somewhat, down to 1E-10, down from 2E-10. PHENIX reports that the backgrounds look somewhat better. Travis tuning the Blue collimators had to pull them out from their set-points to reduce the PHENIX backgrounds reported by scintillator S3.
