MotivationBasic research in nuclear physics
Scattering Reaction Transfer Reaction Charge Exchange
Applications Neutron Detection without using T.O.F method Nuclear Security

Proven TechnologyModeration and then Charge Exchange
Effective as neutron counter Detection Efficiency: 40-45% Timing on the order of μs
Scintillation Effective neutron counter Detection efficiency: 20-25% Timing on the order of ns Energy information using T.O.F techniques

Second PulseReaction
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 PlansFinish the code to analyze the PH, PSD of
second pulse
Search for the alpha particles
