Properties of the University of New Mexico’s solar neutron instrument for use on the NASA 0S0-C satellite were investigated. A sensor model was developed by use of two computer codes. First, the total efficiency of the converters was calculated by a simulation code with a resulting total efficiency at 100 Mev of approximately two per cent of which four-fifths was carbon recoil contribution.
Second, geometry properties of the instrument were provided by a Monte Carlo program, with maximum geometry efficiency equaling about fourteen per cent. These were combined to give a total response profile for the instrument which was expressed in matrix form. This matrix and others representing restricted energy and angular configurations were used to predict the instrument Is response to various environments. Ten proton flares from the last solar cycle were analyzed. The instrument response to the normal background neutron albedo was analyzed also. This method was established as a highly computer compatible means of data reduction.
