摘要

At the Center for High-Power Radiation Sources at Helmholtz-Zentrum Dresden-Rossendorf fast neutron-induced fission cross section experiments on ~(235)U and ~(242)Pu will be investigated by a parallel plate fission ionization chamber. An optimization of chamber parameters was performed using extensive Geant4 simulations with GEF code generated fission observable inputs. Pile-up effects due to the high α activity of the plutonium targets have been considered in a realistic geometry. Beyond that, a setup for the determination of the areal density and homogeneity of targets will be presented with a focus on current simulation work.
