- Joe, Deepak, Volker, Cheryl HAM2 IO install was completed last Friday. The PRM surrogate was swapped to have the HR/HR optic, and to steer the beam to the parking position through the HAM2 top viewport. MC3 OSEM protection baffle was installed using the template sent from LLO. Minimization of the beam once the HWP after IM1 was installed reduced the beam to 7uW at PRM surrogate, which is a good thing since we're still sending the wrong polarization into the mode cleaner. MC1 lower stage OSEMS were adjusted, so MC1's hanging position is unknown, so this morning I'll be working on it's alignment to get the mode cleaner flashing.
