BeamLine calibration + general Run 16 calibration status

Speaker : G. Van Buren ( BNL )


Talk time : 12:20, Duration : 00:20
  1.  AuAu200
    • Large calibration production and supplement for multiple tasks were complete [done]
    • TPC
      • Drift Velocities [done]
      • SpaceCharge & GridLeak [done]
      • dE/dx [in progress]
      • Hit errors [to-do]
    • HFT
      • Status/masking tables calibrated during the Run, with touchups from the large calibration production [done/in progress]
      • Alignment
        • Internal completed using zero-field cosmic rays, needs uploaded to database [done/in progress]
        • Global HFT-TPC in progress using field-on cosmic rays [in progress]
          • Final check will require a calibration production of all Run 16 field-on cosmic rays, near the end of Run 16 [to-do]
    • TOF
      • Being reported today
      • VPD (start-side)
        • Performed during the Run (required for trigger's vertex cut) [done]
        • Re-checked using the large calibration production, but evaluating impact with MTD [in progress]
      • BTOF (stop-side)
        • Calibration production required for alignment check and timing provided and being examined [done]
    • MTD
      • Calibration production provided (statistics reported as sufficient); needs field-on cosmic ray porduction too [in progress]
        • Some timing changes were seen that are not fully understood; expect cosmics to clarify
    • BeamLine
  2. dAu200
    • TPC
      • Drift velocities [done]
      • SpaceCharge & GridLeak
        • Initial calibration unable to figure out calibration procedure problems before end of data acquisition [aborted]
        • Final calibration completed [done]
      • dE/dx needs a calibration production [to-do]
      • Hit errors [to-do]
    • HFT
      • Status/masking tables during the Run [done]
      • Alignment will not need re-done
    • TOF
      • VPD calibration during the Run [done]
      • BTOF should be able to use same calibration as AuAu200
    • MTD
      • Should be able to use same calibration as AuAu200
    • BeamLine [to-do]
  3. dAu62
    • Similar to dAu200
    • TPC SpaceCharge & GridLeak:
      • Initial calibration struggled for same reason as in dAu200 [aborted]
      • Final calibration neded [to-do]
  4. dAu20
    • TPC SpaceCharge & GridLeak:
      • Initial calibration unable to figure out issues [aborted]
      • Final calibration is needed (small but visible distortion of a few mm in Offline QA) [in progress]
    • HFT not run
    • Otherwise like dAu 200 [to-do]
  5. dAu39
    • TPC drift velocities affected by June 14-20 issues [in progress]
    • TPC SpaceCharge & GridLeak:
      • Initial calibration being attemped again [to-do]
      • Final calibration will be needed if it was needed for dAu20 [to-do]
    • HFT not run
    • Otherwise like dAu200 [to-do]
