A 235U and a 242Pu parallel-plate fission ionization chamber will be used to investigate fast neutron-induced fission cross sections at the Center for High-Power Radiation Sources at Helmholtz-Zentrum Dresden-Rossendorf. To optimize the chamber parameters extensive Geant4 simulations with GEF code generated fission observable inputs have been used. Pile-up effects had to be included due to the high α-activity of the plutonium targets. For the determination of targets surface density and homogeneity an α-spectroscopy setup was developed and simulations related to that will also be presented.

Keywords: Neutron-induced fission cross sections; Stopping power of fission fragments using Geant4; Minor actinide target characterization; nELBE
