Some notes about the setup and work at the PSL table today, Jon can add to / correct me.

  • All equipment for the phase locking now sit on a cart that is on the west side of the MC beam tube, near ITMX chamber.
  • Cables have been routed through the space between the PSL enclosure and the optical table.
  • HEPA was turned up for this work, now it has been turned down to the nominal level of 30%.
  • Alignment into the PMC had degraded a bit - I tweaked it and now MC transmission is up at ~15600 which is a number I am used to. We still don't have a PMC transmission monitor since the slow ADC failure.
