TCS maintenance morning

Nutsinee, Elli

Both CO2 lasers tripped, about 10 minutes from each other, the H1:TCS-ITMX_CO2_INTRLK_RTD_OR_IR_ALRM had tripped, due to Filberto's working near Ham4 (the temperature sensor which will eventually be attached to the viewport is currently on the electronics rack next to the CO2 laser tables and is sensitive to people working near it.  CO2 X power on the IMTX has been returned to 0.22W. 

HWS X was working.  Then we touched the picomotors on the periscope mirrors and lost the alignment due to hysteresis. Dang.  HWSY SLED is aligned to irisis, green beam still clipping somewhere.

We have decided to leave EY HWS plugged into its separate power supply for the time being.
