ABSTRACT:
In a neutron and/or gamma radiation detection system, a large reception surface for the radiation to be detected is formed on a body of scintillation material which is adapted to convert neutron or gamma radiation into light energy. A large number of fiber light conductors is embedded in the body of scintillation material such that the fibers extend essentially parallel and fully across the reception surface of the body of scintillation material. The light energy, upon propagation along the fiber light conductors, is coupled into the conductors along the surface of the fibers, which fibers are anisotropic.
This arrangement permits the use of anisotropic light conductor systems which, in contrast to optically isotropic systems, provide for a separation of light collecting and light transmitting functions which results in a substantial reduction of light absorption losses during light transmission so that most of the light energy coupled into the fiber light conductors reaches the optoelectronic amplifier coupled to the end of the light conductors.
