	Status: warming. All mixture in dump. LN2 traps warm and pumped out. Contaminants from fridge were pumped out at 220 K. Turbo pumping on cryostat vacuum jacket overnight.
0938	Pump manifold pressure = 3.0e-5 mbar
0941	Close cryostat vacuum jacket valve.
1120	MC(Cernox) = 286.8 K (57 F)
1150	Lower cryostat into pit, erect clean tent
1630	MC(Cernox) = 293.2 K. That's 20.1 C, a bit cooler than the 24.0 C in the lab. But it looks like it's still rising, since dropping the cryostat.
1640	Experiment more with DCRC1:

Plug DCRC1 into mini-bob and plug in power
connect via telnet
rd 0: this is updating, different value every time. not stuck
rd 14: this reads 0. rd 2 and rd 3 are 0.
wr 2 00F0, wr 3 1728. Then rd 14, non-zero value. rd 14 repeatedly - it's value keeps changing.
On ODB enable only DCRC1, set as master. Then start programs. rd 0 and rd 14 are still updating. wr 2 and wr 3 have the same values as I entered.
start run with MIDAS, then check rd 0. Updates for 20 seconds, then gets stuck.
also rd 14 is stuck. rd 2 is updating
stop run, rd 2 is no longer updating. rd 0 and rd 14 still stuck.
rd 2 = 00E5, rd 3 = 4CA8. Try changing these - the changes register, but rd 14 and rd 0 don't change.
stop programs. DCRC is still stuck.
power cycle DCRC.
repeat 1-7. DCRC takes longer to get stuck, somewhere between 3 and 4 minutes.

1715	DAQ computer (jiajin) is now stuck. Actually can still type in the telnet session but can't click on any other windows. So can't stop the MIDAS run. (My desktop computer is also stuck so maybe a problem with all the Physics Linux machines.)
