Previous Day

	Setup: iZIP mode, DIB1/2/3 → cables → 3.2 MHz filters → DCRC55/33/50
	Taking Y-Be data overnight. Last flash at ~7:05.
0915	Tower/MC(H35)/MC sensor/Cold Plate = 31.8/28.3/41/153 mK, Still = 1.07 K / 0.085 mbar, G1/G2 = 120/110 mbar, 1K Pot = 1.50 K / 1.9 mbar, Main bath = 43.8%
0920	Remove Y source from fridge.
0925	Tweak 1K Pot needle valve open additional 5 degrees. After 15 minutes Pot is at to 1.7 K / 15 mbar, Still at 0.12 mbar, Tower at 31.1 mK
0930	Fill LN2 cold trap Dewar.
1012	Attach pi-filter switchboard to DCRC50 with only SQUID bias and QET bias lines filtered (switches 3,4,35,19,7,8,38,23). Repower DCRC50. Zap SQUIDs.
1031	Perform mini IbIs (Later found to be invalid. See below) on DIB3 in with pi-filter switchboard attached SQUID bias, QET bias lines filtered. Unpower DCRC50.
1142	There were hints that the above arrangement had lower parasitic power than with all switches on. Redo All switches on test for comparison (Later found to be invalid. See below). Turn on all pi-filter switchboard filters. Repower DCRC50. Zap Squids.
1345	After mini IbIs for all switches filtered configuration, unpower DCRC50. Noticed that DSUB filter was still attached along with pi-filter switchboard, meaning that this mornings tests are invalid. Time to redo them.
1350	Attach pi-filter switchboard with all switches ON to DCRC50. Repower DCRC50 and zap SQUIDs.
1430	Perform mini IbIs on DIB3 with pi-filter switchboard attached and all lines filtered. Unpower DCRC50. Switch off lines so that only SQUID bias and QET bias lines are filtered (switches 3,4,35,19,7,8,38,23). Repower DCRC50. Zap SQUIDs.
1505	Perform mini IbIs on DIB3 with pi-filter switchboard attached and SQUID bias and QET bias lines filtered. Unpower DCRC50.
1530	1K Pot down to 2 mbar, tweak 1K Pot needle valve open additional 5 degrees.
1535	Switch on filters for QET Return lines (switches 1,13,14,32,17,29,47,48,33,5,9,10,28,36,40,43,44) and SQUID Return lines (switches 20,34,24,39) in addition to QET bias and SQUID bias lines (switches 3,4,35,19,7,8,38,23 from earlier). Reattach pi-filter switchboard to DCRC50, repower DCRC50. Zap SQUIDs.
1605	Commence LHe transfer (33.0%).
1620	Perform mini IbIs on DIB3 with pi-filter switchboard attached and SQUID bias/return and QET bias/return lines filtered. Unpower DCRC50.
1640	Cease LHe transfer (91.1% KNOW).
1650	Fill LN2 cold trap full.
1655	Place Cf source inside shield near detector for overnight activation.
	Release pressure from Main Bath.
