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 (carbon target)
