PARTICIPANTS: Fernando, Bogdan, Carlos, Emmanuel, Vladimir, Tanja


DISCUSSION LOW VOLTAGE STRATEGY

  • Choice of cables
  • Size of cables: 22 AWG (thicker cable) instead of 24 AWG?
  • worth looking into if there is a solution that offers lower resistivity
  • however, need to pay attention to size of connectors that fit on board, etc.
  • Is there a AWG available to handle one column?
  • Action Items:
  • Review calculation and see what cable + connector combination would be possible
  • Fernando provide an example of a cable that would work - Orsay team can then optimize
  • Option of Voltage stabilizer/regulator
  • would have additional power dissipation but provides stabilization
  • obtaining negative regulators may be challenging
  • if components available then good thing to so (as long as power dissipation not an issue)
  • Review of power consumption:
  • (optional) stabilizer power consumption ~<20mW (for +- means ~40mW)
  • (need) one amplifier dissipates ~120mW
  • (need) one divider disspates ~500mW - defines cooling capacity
  • total power dissipation increases to ~660mW (originally assumed ~500mW cooling capacity)
  • Action item:
  • Is cooling capacity sufficient to handle LV? - 660mV instead of 500mW --> need to test

HV DIVIDERS

  • Plan final tests next week
  • Action Item: Vladimir check setup on Monday
  • Final Layout
  • Production


NEXT MEETING: WEDNESDAY 22 SEPTEMBER AT 10:00AM ET
