Cheryl, Peter, Joe Gleason, Stefan After making sure the input mode cleaner was flashing with a good alignment, we did the following alignment work for HAM2 and HAM3: - IM1/IM2 tweak-up to center through the Faraday. - IM3/IM4 tweak-up to center on irises marking the center of PRM and PR2 - Rotated the PSL polarization by 90deg (45deg on the lambda/2 stage) (required because of the REFL periscopes on HAM2) - Installed irises for marking the IM transmitted beam, just after MC3 and before PRM - Installed re-direction mirrors to redirect the IMC REFL into the path of IMC trans (alignment using the just installed irises) - Joe is still aligning the last steering mirror in the IM4 transmitted path.
