Improved neutron fluence accuracies in activation experiments
The more recent activation cross section work at CBNM Geel has been performed in cooperation with KFA Jülich and IRK Vienna. This report presents two aspects of improved accurate neutron fluence determinations. The first is the correct averaging of two sets of independent fluence results obtained by a recoil proton method and by aluminium activation, taking into account the necessarily existing correlations. The second is a method to determine more accurately the neutron source position by using the activity ratios of symmetrically exposed samples and a-priori information on the neutron source property and the excitation function.
