We opened up the corner station hartmann table to have a peek at the IX HWS, since TJ suggested there might be some phase camera components blocking the beam.
We noticed that through the IR viewer, and on the medm screen, the IX source had much much less power than the IY source.
We saw what we think is the phase camera, next to the Hartmann camera, it doesn't seem to be blocking the beam. We also saw a couple of filters in the beam, circled in the attached photo. We scootched them out of the beam path, since there are no filters like that on the IY path. If needed we can put them back easily.
We were unable to connect to the camera using tmux, presumably some hardware needs to be switched in the MSR. We know that the IX Hartmann is clipped in vacuum, but still thought it might be nice to take a peek for point absorbers.
The Basler camera on that table was used to look at the beam profile free of the Hartmann plate.
H1:TCS-ITMX_HWS_SLEDPOWERMON recorded 0.08mW when we turned on the SLED. It's been low for a while but see the attached ndscope of it slowly decaying from 0.2mW 2.5 years ago.
ITMY is at 2.3mW so before seeing images we may need to perform a SLED swap. I checked the TCS cupboard and we had one new SLED for each ITMX and ITMY.
