1. A method of locating and identifying a source of incident neutrons comprising:
positioning multiple scintillator bars, each with a first end and a second end, so that such bars are substantially parallel wherein such bars are radially symmetric and all of the scintillator bars have the same diameter; attaching a light sensing means to the first end and to the second end of each such bar; detecting, for each of a series of incident neutrons, that a given incident neutron produced a first n-p scatter in a first such bar; detecting, for the series of incident neutrons that the given incident neutron produced a second n-p scatter in a second such bar, wherein the first n-p scatter occurs prior to the second n-p scatter; measuring the positions and relative times of the first n-p scatter and the second n-p scatter; measuring the energy of a recoil proton produced by the first n-p scatter; calculating an event circle for the given incident neutron thereby locating and identifying a source of incident neutrons. |
