2018 Data: Analysis Summary
Target Information
- Target configuration report
- Note: cryotargets need to subtract window thickness and apply a correction of 0.996 due to length contraction at low temperature
- Solid target notes
- Note: I think there was a transcription error for the carbon target. The report says 0.5244 g/cm2. I get 0.5224 g/cm2 from the notes above.
- Beam and target offsets:
- Analysis of SHMS/HMS C data (log entry needed)
- Offsets to put in MC (from email from Abishek)
- x-spec offset = +0.127 cm
- y-spec offset = -0.057 cm
- x-beam offset = (0.073 - x-bpm) cm
- z-target offset = 0.212 cm
BCM calibration
Efficiencies and corrections
- SHMS
- NGC efficiency lookup table: F2 elog 317
- Calorimeter efficiency: F2 elog 287
- Can't find log entry with polynomial form
- HMS
