Abstract
A spherical neutron counter for spectrometry and dosimetry has been de veloped. The counter consists of a spherical polyethylene moderator an d three slender He-3 position-sensitive proportional counters inserted into the moderator. The thermal neutron distribution in the moderator , which is a function of the energy of the incident neutrons is obtain ed with the proportional counters. Characteristics of the counter have been studied with experiments and Monte Carlo simulations. Also shown are energy spectra of a Cf-252 neutron source that are obtained by an unfolding method using the thermal neutron distributions as response functions.
