  • Multiplet mode in dithering (spring)
Dithering analysis for PREX system
Rich 240 Hz speed/efficiency
Detector prep Dustin Cosmics Checkout, PMT linearity tests, LED system, Mounting hardware and angles
  • PMT DC linearity (Luis)
    • New (Bogdan) Burle PMT
    • Photonics PMT
    • New/Old base

Compton polarimeter Mark
Alex, Bob

Electron detector (Alex, Bob)

    • repair edet planes
    • complete tests
    • reinstall
Mark Increase IR cavity power Begun testing moving lense 3 to improve mode matching. Significant steering observed -> might take a while to optimise
