Starting a New Run Period

Preparations

Check-out

• Several data types stored in the data stream rely on shared-memory and other ancilliary processes to be running. So it's good to check these. Make sure that BOR records are being written early on in the raw data, that board configurations are being written into each event, and that EPICS events are showing up in the data stream
  • Note that the first two events in a run are generally control events: Prestart and Go. Then usually the BOR event should show up
• Make sure parameters are being reasonably propagated into the RCDB

Calibrations

• Look at occupancy plots to find dead channels
• Check firmware if there's new firmware.
  • So far, this has only really been tested for the fADC250's
  • hd_root -PPLUGINS=lowlevel_online -PLOWLEVEL:CHECKEMULATION=1 data.evio
    • This prints out cases
  • hd_dump -PEVIO:VERBOSE=10 -DD
• Start the timing calibrations
