LERF FL02 cryomodule insulating vacuum

Log Number: 4130495Logbook(s): Body: 

Insulating vacuum much cooler than vault ambient temperature. insulating vacuum turbo pump / rough pump appears to be okay. The pump doesn't
have a working pressure gauge. Decided to install another turbo pump with a working gauge at the downstream isolation valve. Pressures 7e-4
with both pumps open to the insulating vacuum. Note. 7e-4 while at 4k.
Also. Beamline vacuum came up 2 decades transitioning to 4k.
