Status	Warming. All mixture in dump. LN2 traps warm. 1K Pot needle valve open. Nitrogen exchange gas in IVC. Cryostat vacuum jacket turbopumping out.
1000	Turbo on cryostat vacuum jacket = 34 nbar. With pump valved out, → 1.9 µbar. With pump valved in again and vacuum jacket port valve closed, → 19 nbar. So the vacuum jacket has more residual pressure than the hose does.
1010	Close cryostat vacuum jacket valve.
1350	Check IVC pressure: 0.64 atm. (surprised it's this low.) Let more N2 into IVC until it reaches 1 atm
1640	Disassemble and remove lead/poly shield
