HWS 
- continued with alignment, position detectors were aligned using retro-reflected 532nm beam. 

TCSX
- had been running since Monday am, turned off for a couple of hours this afternoon to re-route some water lines to allow the FLIR camera, screen and enclosure to protect the camera to be positioned on table. 
- FLIR camera connected up using laptop and the camera side of the screen was imaged.
- Monitoring beam alignment was adjusted to centre the beam on this screen. Images taken and CO2 power onto this screen was slowly increased using rotation stage. Up to ~0.5W was projected onto this screen. Attached images show zero incident power (beam dumped but laser on), and ~500mW of incident power.
