Presentation Transcript

  1. Run 13 Offline Analysis • Complete run list (785) • 4 TB • data+log+root • Backup in hpss • /home/u/cnipol/jet_run13@ • Fill_#####.tar.gz (includes good run list) • Offline analysis on eic0007 • Include monitoring plots • Asymmetry calculation for elastic p+p (-t) • T0 determination • Background studies • Standalone calibration (Luis) • libJetCalibration.so

  2. Online Plots

  3. Kinematics sum over all jet center downstream

  4. New T0 determination Use elastic p+p signal in good energy range Determine mean T0 in slices of energy Remove parts of the distribution when rms is too large Calculate mean T0 over good energy range need to refine

  5. + + + + + - - + + - + - + + + + - - - - + - - - + - target asymmetry: - filled bunches signal beam - abort gaps (upstream) beam asymmetry: - filled bunches both beams - abort gaps other beam + - - + + - + - + + + - - + + - - -

  6. Single Beam Studies left right

  7. Abort Gaps all other

  8. Fill 17600 (1)

  9. Fill 17586

  10. Background Fractions Fill 17586, 15 hours Revolution counter: 107 ≈ 21 minutes Each point here is ≈ 10 minutes Will need accurate T0 calibration

  11. Fill 17600 1/2

  12. Fill 17600 2/2

  13. Background Fractions Fill 17600, first 7 runs

  14. Background Fractions Fill 17600, second 7 runs

  15. Detector Geometry 5 MeV 1 MeV 1 MeV 6.3 mm 5 MeV 35.7mm background region signal region cm Calculate Δz with d and ϑ

  16. Fill 17586
