Abstract :
A method of calibration of the Moxon-Rae type gamma-ray detectors used in neutron capture crosssection measurements with underground nuclear explosions is described. The method consists of measuring the activation and detector signal in individual resonances in samples of 197Au and 238U exposed to a neutron beam from an underground nuclear explosion. The resonances are resolved by time of flight. Since both the activation and the corresponding detector signal are known, the efficiency can be determined without measuring the incident neutron flux or sample capture cross section.
