Spectral neutron flux from 10 meV up to 100 MeV in the Dresden Felsenkeller — •Thomas Hensel1,2, Daniel Bemmerer1, Marcel Grieger1,2, Stefan E. Müller1, Tamás Szücs1, and Kai Zuber2 — 1Helmholtz-Zentrum Dresden-Rossendorf — 2Technische Universität Dresden
Neutron flux measurements with moderated 3He proportional counters have been performed in three distinct laboratories of the underground site Felsenkeller. The six polyethylene moderators of a previous measurement have been complemented by a new moderator with a lead liner to provide information about the neutron flux above 10 MeV. The results quantify the shielding’s influence on the neutron flux and inform the planning of future underground laboratories.
