Green beam was injected into TMSY and into EY, green centering on TMS QPD is working but no retro reflection from EY. I scanned TMSY PIT and YAW and observed green beam in ISCTEY but it would be much easier to just look at the beam in chamber. Will continue tomorrow.
EY was put back into laser safe.
The lack of retro-reflection from ETMy was likely due to an optic face shield being installed. The shield was removed this morning so TMS work can continue.
