Paper Abstract

Potentially low cost and large area polycrystalline mercuric Iodide (HgI2) is one of the preferred materials for the fabrication of room temperature X-ray and gamma-ray detectors. In this paper, the technique of fabricating polycrystalline HgI2 detectors was studied and the energy resolution of 13.1% for 5.5 MeV 241Am α particles at room temperature was obtained for the first time. The optimal choice of particle injecting from negative interface enhances the collection efficiency.
