This morning, around 8:20 UTC, both CO2 lasers and chiller have been turned off. The operation allowed us to disconnect the cables of the WI chiller heater, that seems to be one of the responsibles for a comb noise in the RFC frequency noise (36012).

The WI laser and chiller have been turned on again around 8:36 UTC. The NI laser and chiller are still off, to check if the noise disappears in the INJ signals.

At present there is a communication problem (work in progress) with the WI chiller, that appeared as soon as the chiller was turned off.
