As reported in 64824, the ITF could easily reach LN3. Thus, according to the commissioning crew, we proceeded to the WI CO2 bench to:
- remove the extra thermal camera installed on one of the BS flanges
- remove the extra optics installed on the bench during the replacement phase
- re-install the plexiglass between the CH plane and the lower part
- re-connect and re-operationalize the ISSIN photodiode to monitor the total power emitted by the laser (see attached figure)
We concluded these activities at 17:00 LT.
We left all the CO2 actuators in the 'run configuration'.
