Abstract
Adequate prediction of the activation and transmutation response of materials under fusion neutron irradiation is heavily reliant on the quality of the nuclear data used in inventory calculations. Foil irradiation experiments have been conducted using a 14 MeV DT neutron source hosted at AWE Aldermaston in the UK as part of an effort to improve and increase the integral data available for input to the nuclear cross section database. An automated processing system has been developed to handle the huge number of γ-spectra generated from these experiments. As well as providing a framework in which to process a large number of separate experiments automatically and in a consistent manner, the system also allows for the time-dependent γ-spectra available for an individual experiment to be considered as a whole, thereby improving the accuracy of measurements in comparison to those based on a single time-integrated spectrum.
