# General
## Meeting moved to 10 am
## Offset for the BPMs found.  Worst case 1 mm.  BPM offsets will be uploaded, Dave to take care of this.
## Collimator was checked in October, wait for survey data.
# Laser
## Cavity is not locking.  Mode matching is off.
## Changed the fibre amp (tried different see laser but that didn't improve things.)
## Today realigning PPLN to get a better shape. (but highest priority is to get to high current.)
# Electron Detector
## FSD is fixed
## QWAD adaptor tested and seems to work.  Will insert when beam is threaded.
## Progress made on scaler readout butt still issues to resolve.
## DAQ is generally is good shape.
## Is helicity signal in the DAQ?
## Need to work on the software (decoding of VTROC.)
# Photon Detector
## Looking into a waterproofing solution.  Current plastic doesn't fit, try to get a bigger piece of plastic.
## All cable ends have been replaced.
## Finger scintillators behind each tungsten finger was checked (take a picture.)
# Analysis
## Updating online analysis for CREX (cosmetic)
## Make rootfiles available for use in PREX background studies.
