Abstract
For the design and set-up of neutron induced prompt <TEX>${\gamma}$</TEX>-ray spectroscopy system using <TEX>$^{252}Cf$</TEX> neutron source, the effects of shielding and moderator materials have been examined. The <TEX>$^{252}Cf$</TEX> source being used for TLD badge calibration in Korea Atomic Energy Research Institute was utilized for this preliminary experiment. The <TEX>${\gamma}$</TEX>-ray background and prompt <TEX>${\gamma}$</TEX>-ray spectrum of the sample containing Cl were measured using HPGe (GMX 60% relative efficiency) located at the inside of the system connected to notebook PC at the outside of the system (about 20 meter distance). The background activities of neutron and <TEX>${\gamma}$</TEX>-rays were measured with neutron survey meter as well as <TEX>${\gamma}$</TEX>-ray survey meters, respectively and the system was designed to minimize the activities. Prompt <TEX>${\gamma}$</TEX>-ray spectrum was measured using <TEX>${\gamma}$</TEX>-<TEX>${\gamma}$</TEX> coincident system for reduce the background and the continuum spectrum. The optimum system was designed and set up using the experimental data obtained.
