Corner HWS table:
- both end-X and end-Y in-air optics have been aligned (using the fibre coupled 532nm source) from the source to the periscope. Slight tweaking may be required once the SLED is connected up.
- air lens and collimator temperature sensors for both end-X and end-Y are connected up and are working
- HWS for both end-X and end-Y are yet to be assembled/installed
- image of the corner HWS table attached

TCSX:
- laser has been operating all day. Thomas working on connecting up FLIR camera computer. 
- laser will be left running again overnight to allow performance monitoring

TCSY:
- alignment confirmed through the AOM, while the picomotor mirrors were repositioned. Alignment is now through the second pick off optic, which is just before the HWP and polarisers. 
- CP power control polarisers were removed and checked for pitching using the reflection from a HeNe (set up to be at a flat 4" beam height). Initially the first polariser had pitched the beam down 0.25" at a distance of 20". This pitching was removed by loosening and retightening the bolts that secure the polariser mount to the mounting bracket. Polariser plate was also observed to move in this mount, further changing this pitch. This polariser plate is secured in the mount using a nylon screw, and when tightened improves this a bit. Second polariser appeared to be slighly better. Further investigation required.
