    • Timing on the order of ns
    • Energy information using T.O.F techniques
experimental set up
Experimental Set-up
  • Two PMTs attached to a 10Boron loaded
    • Analog
      • MPD-4 -> TAC
    • Digital
      • Digitizer
  • Sources used
    • 22Na (Calibration/Testing)

Pulse Shape Discrimination

second pulse
Second Pulse
  • Reaction
    • 10B + n -> 6Li + α + ϒ(480 keV)
  • Shows that all the energy in the initial reaction was released in the scintillator
  • Can only be detected with the digital set up
future plans
Future Plans

Finish the code to analyze the PH, PSD of second pulse

Search for the alpha particles
