Abstract

The CSPD-1 γ-ray vision system has been constructed for the energy range from 100 keV up to a few MeV, which encompasses most energies of γ-ray radiation from the radioactive nuclides of interest to nuclear facilities. The angular resolution of the system can be varied from about 7° down to 3° FWHM. The energy resolution at 662 keV is 0.8% or 8.9% FWHM depending on which of the two detectors are used. The detected spatial distribution of γ-rays is overlayed with the video image taken from a small CCD camera mounted on the side of the collimator. This enables immediate localization of the radioactive area. Some results obtained at the Molten Salt Reactor Experiment (MSRE) at the Oak Ridge National Laboratory (ORNL) are reported, and recommended improvements are discussed
