Prof. Paul suggested to check if there is any other remote sources that might be leaky since he thinks we may have fixed the earlier leak with a sharp time constant.

I redid the checks on the turbo pump Tee region which is still slightly leaky but can be valved out in normal operations (one remote source).

We are proceeding with the cooldown. LN2 transfer will be done next (today or tomorrow).

Electrical checks look fine.

Need to do a few more rounds of cryocleaning. Last cryocleaning contaminants ~ 150 mbar. Did another one yesterday.
