Target cool-down completed.
Coolant return temperature (loop 2) is 27 K and will continue to
decrease slowly. Supply is 24K (Hall A side) and 17.6 K (ESR side).
They are also slowly decreasing.
It will take another hour or so to stabalize.
Scattering chamber vacuum only dropped to ~1.5*10-5. May decrease a little more with continued cooling. Not ideal (usually can reach 10-6). Hopefully it will stay low.
I set alarm for vacuum to be HI=5*10-5, HIHI=1*10-4, for return
temperature HI=30, HIHI=32.
