  1. PHENIX Run12 Spin John KosterRBRCRSC Meeting2012/05/11

  2. PHENIX Integrated Luminosity

  3. Achievements • Precision/low-x ∆G measurements • New forward EM calorimeter electronics installed • Better triggering • Several special fills for studying systematic errors • Wμ • RPC1 installed • Offline data readout commissioned • Online trigger is in fine-tuning stage • Trigger is in fine-tuning stage • VTX/FVTX installed and commissioned • FVTX is a new detector for this year • Increased use of online polarimetry.

  4. Muon Trigger Rejection Slide from Yoshi-mitsuImazu

  5. Muon Trigger Turn-on Curve Slide from Yoshi-mitsuImazu

  6. Local Polarimetry Goal zone for residual polarization Some large outliers LPOL team: Ciprian Gal, Sanghwa Park, Josh Perry

  7. FVTX and MuTrMatching MuTr Absorber x FVTX FVTX-MuTr Match, dx x x (dx, dy) South x X x x • Loop over MuTr tracks and look for matched FVTX tracks. • Best matching tracks peaks at 0. • We expect a few cm window due to the multiple scattering in absorber. Simulations use 3cm windows for matching. • It will be improved once we finish the detector alignment. (FVTX alignment and global alignment) dx (cm) Slide by XiaorongWang and Jin Huang

  8. For next year • I expect less commissioning time  better data-taking efficiency at the beginning of the run. • Would be great to continue taking 1 polarization measurement half-way through the fill. • Will work on data-taking efficiency during the CuAu run • Would be great to improve this number.
