Calibration data needs as of Oct. 6, 2015

Detector Status Data in Hand Est. Data Needed Est. Running Time Notes
BCAL More Needed 130k pi0 25-50x pi0 cluster energy > 750 MeV
CDC More Needed
FCAL More Needed 125k 10x pi0 cluster energy > 1 GeV
FDC More Needed 3 shifts, 10^-4 radiator, 100 nA, no field needed
PS/PSC OK
Start Counter More Needed 80 M tracks 10x basic calibrations are good, more refinement possible
TAGH OK
TAGM More Needed 10 M - 50 M
TOF OK need to verify stability of calibrations with more data

Notes

  • Data needed depends strongly on S/B, especially for calorimeters.
  • Lowering thresholds can have a large effect, too
  • SC run list: 2931, 2932, 2933, 2934
  • BCAL/FCAL run list:
  • CDC/FDC will need more data to calibrate fADC125 algorithm when it's deployed.

Scaling from 6 GeV to 12 GeV

  • 6 GeV settings: 5.5 GeV e- beam, 50 um diamond radiator, 5 mm collimator, E(gam) = 2 - 5.5 GeV
  • 12 GeV settings: 12 GeV e- beam, 20 um diamond radiator, 3.4 mm collimator, E(gam) = 7 - 12 GeV
  • rate(12 GeV) / rate(6 GeV) ~ 80% [using cobrems in bggen, incl. plastic target on nose removal in 12 GeV era].
  • Geometrical factors: (12 GeV/6 GeV)
    • SC - ~1x (straight section drives needs)
    • BCAL - ~1x (both photons in BCAL)
    • FCAL - ~8x (both photons in FCAL)
