Abstract

In this report, we present a newly developed hybrid resistive plate chamber (RPC) for the detection of low-energy neutrons. Lithium-fluoride (LiF) enriched for the 6Li isotope was chosen as the material sensitive to low-energy neutrons for the construction of the hybrid RFC. The LiF-coated RFC was tested by using the 252Cf neutron-irradiation facility at the Korea Atomic Energy Research Institute (KAERI). The detection efficiency of the double-layered LiF-coated RPC to neutrons in the energy range from 10 to 560 meV was approximately 1.6 %. We obtained reliable efficiency plateaus over a wide range of electric-field intensities.
