  • 2:45pm: re-aligned optical setup to horizontal reference
  • 2:55pm: installed in chamber, balanced
  • 2:56pm, starting roughing pump
  • 3:06pm, starting turbo pump
  • 4:37pm, excitation at GPS 1162337817: apparently I excited too much and the QPD signals are saturating!

  • 7:58pm: new excitation, amplitude 1kV, duration ~20s. Stopped at ~1162349974. This excitation looks good
  • 9:07pm:Started auto_excite.py script. It will wait 5 hours, then perfom two excitation with above parameters, separated by 3 hours
    • excitations at 1162372099 and 1162382978

  • pumps stopped at 10:00am
