TCSY table chiller lines all replaced and tested

Camilla C, Madi S., TJ S

Just as we did with the TCSX table a few weeks ago (alog90078), we swapped all of the flex lines on the table. Most of this was done last week, but today Madi and I fisnished the last two lines today. We then used the same vacuum trick to suck water into the table lines to "test" the lines over lunch, and then plugged the table back into the full system and slowly turned on the chiller. We had one leak at the laser driver, but cutting and reseating the 1/8"OD tube seemed to fix it. 

While trying to removed the old 3/4"OD return tube from the tee, I managed to bump the iris next to the bottom periscope mirror. We'll have to recheck this when we have beam again and can some HWS tests.

The chiller is running, I'll check on things in the morning.
