Description

The neutron fluence from the 14MeV neutron generator is determined by activation foils and fission chambers. U238 fission chambers are used to record the fluctuation of the neutron flux in time; this measurement is used to calculate the buildup and the decay of foil activity. Then from the foil activity the neutron fluence can be determined. This method is more accurate than the activation method alone since temporal variations of the neutron flux are taken into account. It turns out that with neutron flux variations by a factor of 2 the simple activation method may result in 60% error in neutron fluency. 1 ref., 5 figs. (Author)
