data flow
Data Flow
  • 12 Tell1s plus Odin put together on the crate
  • NZS Data: 4~5kBx12 per event:
    • 2.0 kEvent/s max DAQ with 1 PC.
    • Tested with MEP factor up to 4 (NZS) and 15 (ZS)
  • Too many packets to route:
    • 1 switch is not enough for the Velo (HP 3400)
  • 2 HP3400 work!
    • 1 to funnel, the next one to route.
    • Works, but without Jumbo frames.
  • Artur brings the peacemaker:
    • HP5412 handles the job with no problems.
controls software
Controls Software
  • Velo Front-end, Tell1s, Odin, Hughin and Velo Temperatures controlled by PVSS
    • DIM_DNS_NODE was quite busy…
  • ISEG HV and CAEN LV software from the company
    • Conservative approach.
  • Cooling monitoring as stand alone application (LabView)
issues
Issues
  • Tell1 individual FSM does not check if the CCPC is alive: configuration fails.
  • Network interface on lbh8lx02 started to give up (required a sudo service network restart from time to time towards the end of the test beam.)
  • EB has a small dead time when closing or opening a new file.
  • Optical failure leads to some asynchronization: dangerous with 1 DAQ PC.
  • Some aparent asynchronization between Odin and Tell1s… To be confirmed.
