This night started with the problem of the WI CO2 laser, thanks to Alessio we getting around this issue (a intervention to understand and solve the problem of the temperature is needed), the IFT was locked without any problem and the BS_tx offset tuned, anyway a slow drift of the powers started soon.
At 4:25Lt the ITF unlocked again, but this time I was not able to recover a good value of B5_2f_ACq acting no the BS_tx, also during this second lock a drift of powers started
Vacuum
ToOS9ToEw configured at 3:10Lt (gray flag on the DMS).
TCS
At ~23:00Lt the safety system decided again to switch off the WI laser, to go on with the run, in agree to Alessio the safety system (out of the PLC) has been disconnected to the laser to avoid any other switch off events, the increasing of the laser temperature was already noted and reported by Alessio, during the week-end the status of the laser will be monitored from the control room.
