Before its demise DIANA Hi-TECH, LLC, demonstrated the use of two 50 kJoule Plasma Focus devices for the copius production of fast neutrons, x-rays and radio-isotopes. Such a device is suitable for fast neutron non invasive interogation of contra-band materials including hidden nuclear materials. It could be particularly useful for a fast and fail safe interogation of large cargo containers, or...

Since the dawn of the nuclear weapons era, political, military, and scientific leaders around the world have been working to contain the proliferation of Special Nuclear Material and explosively fissile material. This paper describes the construction of a prototype, directional, fast neutron detector, modeled after the Dark Matter Time Projection Chamber. Fast neutrons are emitted by a host of ...

The mean effective cross sections of 6Li for the (n, u) reaction were calculated for thermal, intermediate and fast neutrons; this reaction is dominant in damage production in LiF crystals. The actual neutron spectrum was determined from measurements of thermal, intermediate and fast neutron fluxes, in the core of the IEA-RI-2MW swimming pool reactor, in high fluence conditions, by the activati...
