FLUKA simulations of neutron transport in the Dresden Felsenkeller — •Marcel Grieger1,2, Daniel Bemmerer1, Stefan E. Müller1, Tamás Szücs1, and Kai Zuber2 — 1Helmholtz-Zentrum Dresden-Rossendorf (HZDR), Dresden — 2Technische Universität Dresden
A new underground ion accelerator with 5 MV acceleration potential is currently being prepared for installation in the Dresden Felsenkeller. The Felsenkeller site consists of altogether nine mutually connected tunnels. It is shielded from cosmic radiation by a 45 m thick rock overburden, enabling uniquely sensitive experiments. In order to exclude any possible effect by the new accelerator in tunnel VIII on the existing low-background γ-counting facility in tunnel IV, Monte Carlo simulations of neutron transport are being performed. A realistic neutron source field is developed, and the resulting additional neutron flux at the γ-counting facility is modeled by FLUKA simulations. – Supported by NAVI (HGF VH-VI-417).
