Abstract

We present the design and the performance of hybrid resistive plate chambers (RPCs). In particular, the electrodes of RPCs were coated with the Gd₂O₃ or LiF powder in order to enhance the sensitivity to low-energy neutrons. The efficiencies were measured by using the ²⁶²Cf source at the Korea Atomic Energy Research Institute. After the background had been properly subtracted, the neutron detection efficiency was determined to be about 4% and 8% for the Gd-coated single- and double-gap RPCs, respectively, at an incident energy peaking at ∼ 75 meV. For the LiF-coated double-gap RPC, the efficiency was about 1.2% slightly depending on the threshold of electronics.
