14 MeV Neutron Detectors

[Objectives]
Tritons of 1.0 MeV produced in the d(d,p)t reaction slow down and may undergo a DT fusion reaction, emitting 14 MeV neutron(triton burnup). The behavior of 1 MeV tritons is important to predict the properties of D-T produced 3.5 MeV alphas because 1 MeV tritons and 3.5 MeV alphas have similar kinematics properties.
14 MeV neutron emission rate is measured for the triton burnup study aiming prediction of the alpha particle behaviors.
