Fission chambers have the advantage of a large ionization signal (∼ MeV from the kinetic energy of the fission fragments) that permits discrimination of low neutron fluxes in the presence of a high gamma background. Self-powered neutron detectors (SPNDs) use a material such as cadmium that has a high cross section for low-energy neutrons.

Further, in gamma-ray astronomy, MeV gamma rays are produced by cosmic ray interactions in the interstellar medium, and can thus be used to probe nucleothynthesis in the universe.

In this paper, we present a high-precision image of MeV gamma rays taken by newly developed 3-D position sensitive Compton camera (3D-PSCC).

A large area neutron proportional counter is constructed utilizing a large sealed metal box. The interior walls of the box are coated with 6 Li enriched metal. A multicelled proportional counter structure within the internal space defined by the box is fabricated using a hydrogenous plastic.

The interior of the box is filled with a counting gas. gamma sensitivities from calibrations both in a reactor and in a gamma cell are given, and the signal levels of self-powered neutron and gamma detectors when applied to power reactors are compared.

A nineteen element mercuric iodide (HgI{sub 2}) detector array has been developed in order to investigate the potential of using this technology for in-vivo x-ray and gamma-ray imaging.

A prototype cross-grid detector array was constructed with hexagonal pixels of mm diameter (active area = mm{sup 2}) and mm thick septa. Self-powered neutron detectors (SPNDs) are used widely in flux mapping, control, and protection of nuclear reactors.
