Abstract
We propose to procure, mount and calibrate at IFUSP a source of low energy neutrons produced by deuteron-deuteron (DD) nuclear reactions inside a neutron gun. For the appropriate characterization of the beam, with proper time tagging and background rejection, associate particle imaging(API) techniques will be used, where the 0.82 MeV $^3$He nucleus, produced together with the 2.45 MeV neu…
