    keyword=MCC visit: no beam for ~ 2 hrs

    @ 0550, Ken drops by. When they try to send beam to hall A, the beam "breathes" (moves around) due to the amplifier warm up. This causes an FSD trip and everyone goes down. Therefore, they will send beam to hall C only. We will have to wait for about 2 hrs before MCC will try again to send beam to us. The only thing that we can do right now is to wait for the amplifier to warm up. Note that the beam does breathe even to hall C alone. However, the breathing is not as bad and therefore they suffer from less frequent trips (when we are down).
