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 - 515 nA-hr
- BCAL/FCAL run list: 2931, 3185 [diamond]; 3079, 3179, 3180, 3182, 3199, 3200, 3201, 3217 [1x10-4 RL amorphous]
- Scaling factor: diamond = 8 x amorphous
- 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)
