Conclusions

  • Very preliminary power budget is as follows:
    • Camera cooling 100W
    • Computing 150W
    • Note: once technical interchange begins need to query actual limits on electrical power available, allowed dissipation within electronics cabinets, and allowed dissipation to chilled fluid being used for electronics cabinets
  • A single "standard" computer could run all of the FTT/NA software (under Xenomai)
  • However, cable length restrictions could force us to use a 2nd low-power computer near to the Andor camera
    • This would require a 2nd temperature-controlled enclosure, so best avoided
    • Once technical interchange begins need to query cable routing and whether a dedicated short cable tray can be installed from Q5 to near the camera, to allow use of 1 computer only
  • JSY suggested GUI could be a separate application that is started and stopped independently
  • EBS prefers C (with threads) ISS interface framework
    • Need to think about what combinations of commands might run concurrently and what thread-safety strategy to employ
Added lines 24-26:
  • JSY: Define software components and inter-component dataflows (hardware-independent)
  • JSY: Ask Chris Mayer for field rotation rate
  • EBS: Look for 1U or 2U computers with 2 PCI slots drawing < 150W
