This morning I found the ITF locked in LOW NOISE 1.

The first part of the shift was dedicated to the maintenance activities:

INF              Standard Cleaning Operations;
                    Oxygen deficiency sensors replacement in Terminal Buildings (external firm);
VACUUM    Standard Nytrogen Refill;
ENV             I.Fiori went in Laser Lab to install and relocated some accelerometers;
TCS             Chiller Check performed at 08:45UTC, the refill has been needed only for the NI one;
SUSP          Sa_PR cooling unit replacement.

After that, started the recovery and still in progress.
