Benchmark of a multi-physics Monte Carlo simulation of an ion guide for neutron-induced fission products

Abstract To enhance the production of medium-heavy, neutron-rich nuclei, and to facilitate measurements independent yields neutron-induced fission, a proton-to-neutron converter dedicated ion guide for fission have been developed IGISOL facility at University Jyväskylä. The holds fissionable targets, products emerging from targets are collected in helium gas transported downstream experimental stations. A computer model, based on combination MCNPX modeling neutron production, code GEF, GEANT4 transport products, was developed. model will be used improve setup with respect collection products. In this paper we benchmark by comparing simulations measurement which were implanted foils located different positions guide. addition, activation titanium foil uranium studied. result suggests that flux high-energy part spectrum is overestimated approximately 40 $$\%$$ % . However, transportation agrees experiment within 10 Furthermore, simulated achieves almost perfect agreement measurement. Hence, conclude after correction flux, well suited optimization studies future designs.
