Abstract

The response matrix of a multispehere neutron spectrometer has been calculated using the ANISN particles transport code and a recent condensed cross-section library. The matrix has then been extended up to 400 MeV. A detailed investigation of several calculation parameters led to the establishment of an improved model of the system. The adjustment of the calculated response functions to the experimental calibration points (8 keV−14.8 MeV) has given coherent results, the deviation of the calculated values from the measured ones being less than 10% for the maximum sensitivity regions. The calculated response functions have been compared to others reported in the literature. Finally the effect of a cadmium shell on the spheres' response has been studied.
