    Entry number 187305

    keyword=cryotarget warmed-up due to no CHL flow. Re-establish CHL flow and re-cool-down in progress.

    I was called in because the cryotarget warmed up and scattering chamber vaccum level went up. Appearantly CHL flow went to 0.
    Talked to Pete Knudsen (cryo group). He told me that our flow dropped
    to zero, so he closed it up. Per my request, he started to open the valve to give us CHL flow. Now we are in the process of re-cool down.
    (Mike Seely came in and he thought probably due to we were taking very small amount of flow that the flow seemed to be zero and cryo group clsoed the valve.) It may take some time (a couple of hours)
    to have CHL stabalized.
