1. RG-A run status

  • running fine with some usual crashes, 14kHz
  • problem with move2silo ...
  • mmft1 procedure in the wiki now
  • maybe create epics alarm on mmft1 busy with instructions how to recycle FTT low voltage; SEU monitor may report radiation problem, will talk to Oracle
  • trigger validation data taken, cooked and skimmed, Andrea and Rafo are processing it; electron trigger rate is 2.7kHz with DC roads and match, contrast to 7kHz without it, validation process will confirm if it is correct reduction and we still efficient
