Agenda

Meeting room=F228 in Cebaf Center

General

  • Ole is getting serious about turning off compton-old
    • I've copied some stuff to /home/compton/compton_old on the new machine
    • Check and see if there's anything I've missed that you think is important
    • 2 items still needed on new compton: Functional VNC server and StripTool
  • Simulation: unified GEANT4-based Monte Carlo update
  • Alignment still needs to be done (next week?)

Laser

  • Replacement power supply should have shipped June 24 - delayed to November 11.
  • Joe Beaufait looked at dead power supply - bad 5V supply: replacement 5 V supply in hand
  • New seed laser installed
  • Removed 5 W fiber amplifier and handed off to Shukui (Injector group) - he wants to check it out
  • Installed 30 W amp
    • Need to find polarization direction (not marked)
    • Power calibration is off - need to set like 6.4 W to get 5 W. [1]

Photon Detector

  • Elog entry from Brian detailing phosphorescence of PbWO4 [2]
  • Detector installation

Electron detector

  • Detector in Hall
    • FSD and "photon stopper" valve: need to test masking
    • VETROC modules ordered
  • QWAD tests: JLab (Hoskins/Camsonne)
  • Image:QWAD tests: Manitoba File:PresentationQWADUofM9142016.pdf
