    keyword=cryotarget warm up

    22:30 Cryotarget (LH2/LD2) are warmed up to above liquid Nitrogen temperature
    (loop2 at >80 K and loop 3 > 75 K). When temperature at around 70K, vacuum went
    up to about 2.4 torr, then came back down. Fans and High power heaters are off.
    The scope shows < 1/2 mm movement. (Expect movement will be mostly when warming from 70K to 300K) .
    Will leave it warm up to tomorrow.
