Gamma and neutron scintillator
A unidirectional spectrometer is described that can detect and distinguish between gamma ray and neutron fluxes. The scintillator has two parallel disposed cylindrical scintillating elements that are made, for exampae, of plastic. The plastic compound of one element comprises only protons or hydrogen atoms, having atomic weight one, and the other element is made of a chemically simiaar paastic compound comprising only deuterium or hydrogen atoms of atomic weight two. The two cylindrical scintillator elements are enclosed within an anti-coincidence or outer scintillator element, with both ends of each cylinder exposed. On the same adjacent ends of each cylindrical element are disposed photomultiplier tubes. On opposite sides of the outer scintillator element are disposed two additional photomultiplier tubes. The cylindrical elements and the outer element are each, respectively, enclosed in a thin coating of aluminum except where the respective elements are in contact with the photomultiplier tubes to isolate the light output from each element.
