General

• New meeting day/time. Wednesdays at 11 am. Next meeting will be 9/19.

Laser status:

• After great mode match, can't couple light into cavity - D.G. thinks mirrors must be damaged. Need to open vacuum, but will wait until after upcoming run.
• Polarization optimization script modifications in progress - not certain of testing status.

PMT/Linearity

• Kent, Adam, Brian will arrange dates for Adam to visit CMU and gain experience with the linearity system.

DAQ:

• Juan Carlos and Jinlong were at JLab 8/30-9/2
• Overall - system looks good. Things to keep an eye on:
  • Cables (need repair) and HV for finger scintillators.
  • Noise trigger pulse suppressed with low pass filter - what's the source of the noise?
  • Epics script stops. Can we make this more robust?

Electron Detector:

• No update.

Simulation:

• Amali posted updated plot - will discuss next time.
