Agenda

• Progress on prototype
• Discussion on trigger/event timing
  • We plan to run MOLLER with a 10us "spin flip" period. The beam travel time from injector to the hall is ~20us, so a new helicity integration window starts in the injector while the old integration window in the hall is finishing.
    • How best to coordinate starting the integration and building events? We had discussed having the time shift done in the TI connection.
    • Should INJ and hall readout be coupled or independent (baseline design concept has them coupled)?
• Signal cable and signal level adaptation
  • For the BPM signals (up to 5V, single-ended signals on coax), what I recall discussing was that we would have an option to short one side of the twin-ax cable, and could also use attenuation to get the signals within the range accepted by the ADC
  • We'd also need some sort of cable adaptation to go from the coax to the twinax
  • Should we think about doing this as some sort of panel to which we connect both cables, or should we think about doing it with a cable that has a twin-ax connector on one side and a BNC on the other?
• Activity updates
• General discussion
