Fridge Status :
Completed the shields assembly and done electrical checks with the SQUETS.
Closing the IVC today and start pumping.
The lifter that we use to raise the tower has threaded rod which has chipped at multiple places. This lead to multiple tries to raise the tower with abrupt movements. It did one sharp move and the tower lowered by couple if inches with a sharp hit ,but i checked later that all connections are still secure. Need to find an alternative to this lift bench during this cooldown.

Overnight pumping donot show much improvement on the turbo pumping. Currently it is pumping on the bellows only. Lowest pressure is 8.6e^-5 mbar
Found this spool of copper wire in the lab and using it as the copper layer on the 1K pot line.

The fridge cooldown procedure has a step to pump out the fridge lines. That same is used for pumping out the he3 trap after applying a heat gun to it.
