Removal of polarization sensors from HWSX Path

Cao, Elli

In order to use the ITMX HWS during TCS commissioning, we have removed the polarization sensor optics which were placed in the HWSX path on the HWS table by HAM 4.  (Placement of the polarization sensors is detailed in alog 24046.)  We removed the PBS and the HWSX_ALIGN_M1 mirror from next to the periscope and have bolted them out of the way behind the HWSX camera for the time being.  We also dumped the two sled beams coming through HWS_ALIGN_BS.  We can see the sled beam on the HWS.  I adjusted HWS STEER M10 (the mirror right before the camera) to center the beam on the camera, and did not touch the periscope mirrors.
