present: Sergey, Stepan, Raffaella, vpk, Ben, Rafo, Eugene, Nathan

1. RG-A run status

problem with move2silo: Saturday morning something broke in scicomp, by the end of day clondaq6 disk was full, we moved to clondaq5; Sunday morning moved back to clondaq6; during next 24 hours clondaq6 never returned to normal fillip about 15-20%, although never became full ether; Monday morning beam stoped, and it took 8 hours for scicomp to cleanup clondaq6 completely; as a reminder, we have 3 machines and corresponding CODA configurations names are PROD65, PROD66 and PROD67 where last digit corresponds to machine where data being written to the disk (clondaq5, clondaq6 and clondaq7)

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

electronics: daq setup in SLAC is ready, Sergey has an account and can run it remotely if needed, all information passed to SLAC

trigger: all lab hardware installed, Ben is working on new trigger firmware, planning to get first version by April 15
