	Status: warming up. All mixture in dump, fridge isolated. LN2 traps warm and pumped out. 1K Pot needle valve open.
1150	MC(Cernox) = 255 K.
1155	Pump out line to IVC with turbo pump, then check IVC pressure. IVC = 5.4 mbar.
1335	Let about 0.87 bar of N2 gas into IVC. There was an increase in MC temperature of about 0.5 K
1348	Remove screws on north shield wall.
1520	Lab = 23.6 C, 22% rel. humid., → dewpoint = 0 C From this and Newton's Law of Cooling/Warming, MC should reach dew point on the morning of the 13th (Saturday). That's good enough - we'll let it warm up without letting gas in the vacuum jacket.
