## The full Compton lock has been off since there was concern it was moving beam at the target.  The simple dipole lock has been on.  Should we turn it on again?  Begin discussion with ops to decide.

## Locking started getting harder. Cranked up sidebands to 300 mV.  Locks easily but drops.  Script modified to search for new lock sooner.  Looks like a big new source of noise.  Old signal generator is worse.

  1. Compton Lock
    1. The full Compton lock has been off since there was concern it was moving beam at the target. The simple dipole lock has been on. Should we turn it on again? Begin discussion with ops to decide.
  2. Photon detector
    1. Discussion about the pedestal jumps.
  3. Laser
    1. Locking started getting harder. Cranked up sidebands to 300 mV. Locks easily but drops. Script modified to search for new lock sooner. Looks like a big new source of noise. Old signal generator is worse.
