On Mac's request we will discuss adding time-over-threshold capability to the DCRB's. If time permits we will hear from Rafo on DC segment finder.

DCRB draft agenda:


  *   cosmic ray set-up
     *   what's the goal?  measure scatter-plot of time vs. time-over threshold; other?
     *   which chamber should we use?  reg.1?
     *   what provides the trigger start-time?
     *   how do we measure time over threshold?  digital 'scope?  flash ADC?
     *   how do we estimate rejection factor?  width of scatter-plot (in ns) compared to Tmax?
  *   DCRB modification
     *   what do pulse shapes (vs. time) look like?
     *   how do we define time over threshold with FPGA's?
     *   do we modify a DCRB?  how?
  *   Any other business?
