    keyword=reset vac pumps on top of sos

    Walter and I reset the vacuum pumps on top of the SOS which service the
    "A"-can. They have certainly been off since the power failure yesterday
    (12/10/01). Bad vacuum in that area would increase the Moller heat load
    as well as make the target cryo behave badly.

    We cannot find a TV camera angle that will show any indicators on the pump
    itself, but Paul B. said that there is a ring of ice that formed on the transfer line
    between the A and B cans as a result of the pump being off. That ice is now
    melting. The ice ring is visible from the upstream hall camera.
