1002 Stop flashing detector.
1005 Fed Cricket 4 pellets.
Filled LN2 cold trap mostly full.
1442 Begin LHe transfer (9.5%).
It seems that once the liquid level reaches ~ 11% the temperature of the mixing chamber starts to increase. I have a hunch this is due to the fact that the helium cold trap is partially emerged out of the bath and when the liquid level gets lower, the helium cold trap is no longer submerged in liquid helium.
1545 End LHe transfer (92.6%).
1550 Begin assembly of shield around the fridge.
Re-connected DCRC31 and reset timing link.
