NeuLAND MRPC-based detector prototypes tested with fast neutrons

摘要

Recent results from a first irradiation of multi-gap resistive plate chambers with fast neutrons are presented. The counters have been built at GSI and FZD. The experiment was performed at the "The Svedberg Laboratory" (TSL) in Uppsala, Sweden, utilizing a quasi-monoenergetic neutron beam with an energy E_n=175MeV. For a 2×4 gap prototype operated at E=100kV/cm, an efficiency of (0.77 + 0.33)% was measured.
