All electrical checks for SQUETS done and IVC is closed now.

A possible cause of the turbo pump failure in the last cooldown is found. Yesterday after I start pumping on the IVC with the scroll pump, I can see that the turbo was not holding below 1e-1 mbar without the scroll pump. This mostly likely is outgassing inside the IVC. I will do a quick leak check today and try to pump it down again to confirm.

Mike emailed this morning that the LHe liquifier is not working well lately and he is trying to repair it from last week. Best case schenario for us will be late next week!

Ping will start cryoclean the mixture from tomorrow with the above timeline.
