  • Two gases are used: 70/30 and 90/10 Ar/CO2
  • Two fADC clock settings are used: 125 and 200 MHz
  • Drift time spectra (DCOG method is used):
90/10 Ar/CO2 drift time spectra.
70/30 Ar/CO2 drift time spectra.
  • Red line is fit to get absolute minimal drift time
    • Best tracking results if extracted minimal drift time + 1 time sample
  • Samples per rising edge
Samples/rising edge - 70/30 Ar/CO2 - 125~MHz clock.
Samples/rising edge - 70/30 Ar/CO2 - 200~MHz clock.
