This page contains a list of analysis tasks that need to be done to quote a polarization number for the electron detector. The items that ate common between electron and photon detector were copied from the photon detector list

Run list

  • Have we identified the major breaks in the data taking (high voltage changes, spot moves, lead thickness, etc)?
  • Is this information accessible and verifiable?
  • Do we have a list of runs that are supposed to be 'production quality'?
  • Modification of this list will continue after replay.

Replay of data

  • Do we have the best BCM and BPM calibrations? Are they active in the analyzer for the appropriate run range?
  • Are the decoder level cuts implemented and verified?
  • Do we have analysis scripts for all quantities? Beam charge asymmetry, beam position, beam slope at interaction point?
  • Do we have the ability to look at all quantities on laser cycle level?


Asymmetry per laser cycle

  • What is the asymmetry per laser cycle?
  • Are there correlations (as expected) between asymmetry and beam position, beam slope per laser cycle?

Polarization per slug

  • What is the weighted mean asymmetry per slug?
  • What is the polarization per slug?

Comparisons

  • Comparison of the photon polarization over electron polarization per slug: ratio, difference, pull plot.
  • Comparison of the electron polarization over Moller polarization.
