DVCS-3 Updates

  • Deadtime analysis in progress: main goals include
  • Determine the livetime/deadtime correction factor (LTCF)
  • Take a trigger rate/live rate and normalize using the current, adjust to the prescale, and then apply the LTCF.
  • To make sure the deadtime is correctly computed, the deadtime, current and prescale factors should be in agreement more than 1%, especially for the range of rates in which the deadtime is linear.
  • Currently analyzing run taken in April 2016, 13418 which was a dedicated run for the deadtime analysis, at three different currents (10, 15, 20 uA) using a liquid hydrogen target.
  • There are other dedicated deadtime runs taken in February 2016 with a carbon target, 12471 to 12476 at a current of ~5 uA with different prescale factors ( ).
