TCS CO2 X-arm laser, short test

Alastair & Greg

Greg is running the TCS x-arm laser for a couple of hours (from 16:41 onwards) so we can start to get some data on stability at LHO. The beam to the CP is blocked so there is no output, and the laser is being run with the table closed.

Shut the laser off at 7:20pm. Rotation stage is non-functional right now, most likely due to the cable dressing that was done at the end of last week. Will try and restart the ethercat chassis during maintenance tomorrow.
