Previous Day

	Status: DCRCs off. Trying to cool to base.
0014	Tower = 28.7 K, G1/G2 = 175.8/362.8 mbar, 1K Pot = 1.660 K / 38 mbar.
0022	Start LHe transfer (MB = 0.5%)
0125	Transfer paused, LHe dewar ran empty. Replace with new dewar.
0155	End LHe transfer (MB = 91.4%)
0205	Fill LN2 cold trap full.
1025	Tower = 28.7 mK and stable. G1/G2 = 171/159 mbar, Still = 0.15 mbar / 2 mW, 1K Pot = 1.67 K / 45 mbar
1025	Lower Still heat to 0.1 mW, then open V14 to let rest of mix into circulation Condenser peaks at 270 mbar, Tower spikes to 108 mK then begins to fall.
1050	Tower down to 51 mK, Still = 1.1 mbar. Close V14
1055	Still = 0.12 mbar. Turn Still heat back up to 2 mW. Still → 0.15 mbar
1100	Tower = 32 mK and falling
1443	Fill LN2 cold trap full.
1445	Tower = 28.3 K, G1/G2 = 168.8/158.5 mbar, 1K Pot = 1.660 K / 40 mbar. MB = 75.9%
1448	Plug in both DCRCs and start DAQ programs. Tower spikes to 170 mK then cools
	Setup: DIB1/3/4 → 3.2 MHz filters 2/3/1 → cable 3/1/2 → gender changer 3/?/2 → HVConn 1/3/2 → HV 1/2 → DCRC55(1)/DCRC50(3)
1510	Tower = 29.7 mK
1515	Some of the DAQ programs had stopped - restart them (dcrc_driver01, towerfe3_01, triggerfe2)
1530	Tower = 29.8 mK
	trying to zap SQUIDs from home - but the DAQ programs are stopping spontaneously, and the DCRC_UI Tools option is a blank screen
1535	Restart MIDAS, then restart DAQ programs. They seem to be staying on. But I still can't see anything in Tools in the DCRC_UI. I'm using the Opera browser, that's the way I do it remotely - it has worked in the past. try again using Firefox, that works.
1545	Try zapping SQUIDs twice on DCRCs 1,3 using gui tool. (Some of the DAQ programs are still turning off spontaneously, not sure this will work.) Got an error, something about tools timeout.
1545	Try disabling DCRC4 on ODB, then restart DAQ programs, then try zap. Seems to work. Tower temperature peak, yeah it worked.
