H2 HWS EY install - tidied up electronics on ALS table
Yesterday, Thomas and I tidied up the HWS electronics on the ALS table that is now at the end station. The two power cables connecting to the Hartmann sensor have been attached and those cables, plus the fiber-optic and temperature sensor cable that go to the Hartmann sensor, have been tied to a post and routed up the cable tray to the HWS breakout box (see attached photo).

The feedthrough panel was replaced with a new version where the 37-pin feedthrough is horizontal and doesn't interfere with the Bosch/Unistrut framing of the enclosure.

We installed the on-table temperature sensor by the second lens in the HWS imaging system (see attached photos). We moved the Hartmann sensor 2" closer to the PBS to get the fiber-optic cable out of the beam path behind it. I still need to lengthen the optical system by 2" to compensate for this and keep the image plane of the ETM on the Hartmann sensor surface.
