    keyword=RF recovery saga

    1) RF recovery did not really start in one of two linacs until source/injector
    ... people were done, around 5:00 PM. This was clearly not an RF recovery
    ... day, it was a maintenance day.
    2) took several hours to get RF recovered and machine back up after source/injector
    ... guys cleared out.
    3) when beam was back, problems with RF (must not have recovered sufficiently).
    ... one cavity kept tripping (even though it was bypassed).
    4) they managed to fix this problem with on-call support, only to then stumble
    ... yet again into injector tune space ... problems with tails on beams causing
    ... problems in machine.
    5) injector on-call is working with them now.
    6) have decided in the interest of not losing another hour dorking with harp
    ... scans, to press on without one as soon as the beam comes back up.
    ... we might do it at an opportune moment tomorrow.
