0945	Filled LN2 cold trap.
1400	External shield put up (no bottom shield).
	Note that in the assembly of the shield, especially installing the poly, the Lakeshore bridge had to be restarted several times. The wiring seems to be very sensitive to the motion around the fridge and caused several instances of “TOver” in the thermometer reading, only to be corrected by turning the Lakeshore instrument off and on again.
1530	Fed Cricket 5 pellets.
1800	Start flashing detector.
1805	Filled LN2 cold trap.

With regards to setting up boards to take data- Zapped all SQUIDS twice. This still didn't resolve the behaviour of the pulses. After seemingly powering the boards earlier, the charge channels had an erratic signal. Discovered that all boards now have a tendency to rail. Manually turned on FET heater for all three, which resolved the issues of the charge channels looking strange. Most likely will have to reset the settings for all the phonon channels, which means modify the DAQ file, but such is the scenario. Will start this tomorrow.
