Performance studies of ionisation chambers for photon-induced fisson experiments — •Marius Peck1, Joachim Enders1, Martin Freundenberger1, Alf Göök2, Andreas Oberstedt3, and Stephan Oberstedt2 — 1Institut für Kernphysik, TU Darmstadt, Germany — 2European Commission, JRC-IRMM, Geel, Belgium — 3Fundamental Fysik, Chalmers teknsika högskola, Göteborg, Sweden
Angular and mass distributions as well as total kinetic energy of fission fragments in photon-induced fisson of 232Th were obtained using a twin Frisch-grid ionization chamber at the superconducting Darmstadt electron accelerator S-DALINAC.
To improve the experimental luminosity, e.g. for future energy-resolved experiments at ELI-NP, while maintaining the overall resolution we are studying a multi-stack ionisation chamber.
We present investigations on the suitability of different gas-mixtures for optimizing the electrode design of said multi-stack chamber.
