Optimising Foil Selection for Neutron Activation Systems

Abstract Neutron spectrum unfolding using activation foils is currently the primary technique planned for measuring neutron energy at first wall of power-generating fusion reactors. Room improvement in effectiveness current foil selection was identified, and a program produced to select procedurally order maximise accuracy procedure. Using Kullback–Leibler Divergence quantify accuracy, unfolded by selected set found be more accurate than used literature.
