Partial notes from meeting

1. Laser
   1. Spent weekend swapping out PPLN--didn't help
   2. Monday changed power supply to RPD, more sideband voltage changes--didn't help
   3. Changed out RPD itself and it works. Locking overnight was good. Alignment improvement made it very stable.
   4. Attempted to use Digilock: was partially successful in that is was trying to lock. The locking module in the rack has failed.
   5. Discussion about what to do for MOLLER
      1. Commercial locking electronics
      2. Replacing legacy hardware
      3. Harden for radiation: move equipment out of hall or replace with more robust equipment.
      4. Understand radiation sources
