This paper introduces a movable detection device for explosives hidden in wall. The device is composed of the 14MeV neutron generator, the silicon detector and Φ76mm×76mm LYSO detector. The γ spectra produced by the inelastic scattering interaction provide the relative counts of C, N, O, which are converted into chemical fractions to distinguish the explosives from the organic compounds. The device using associate particle method reduces the background 200–300 times. The 300g ammonium nitrate and TNT explosive simulated samples placed behind the 15cm-thick and 10cm-thick wall is detected by the device, respectively, when the neutron intensity is 1×107n/s. Compared with other methods, the experimental results show that the device with associate particle method has higher detection space resolution ability and explosives recognition ability. The device can provide the support for the detection of explosives.

In this paper, I discuss the theory behind the use of a dense, concentrated neutron particle-based beam. I look at the particle based physics behind such a beam, when it is focused against solid material matter. Although this idea is still only theoretical, it appears that such a beam may be capable of disrupting the stability of the atoms within solid matter- in some cases by passing great volumes of neutrons between the electron and nucleus thus effectively “shielding” the electron from the charge of the nucleus. In other cases, by disrupting the nucleus by firing neutrons into it, disrupting the nucleus and weakening its bond on electrons. In either case- the resulting effect would be a disruption of the atom, which in the case of material matter would cause said material matter to fail, which would appear to the observer as liquification with some plasma generation. Thus, a dense neutron particle based beam could be used to effectively liquefy material matter. Such a beam could bore through rock, metal, or even thick, military grade armour, like that used on tanks- causing such materials to rapidly liquefy. The denser and thicker the neutron beam, the more devastating the effect of the beam- thus the faster material matter will liquefy and the greater the area of liquification. Such a beam would have applications in Defence, mining and drilling operations.
