Paper Abstract

Mercuric iodide (HgI2) is a well known material for the direct detection of gamma rays; however, the largest volume achievable is limited by the thickness of the detector which needs to be a small fraction of the average trapping length for electrons. We are reporting here preliminary results of using HgI2 crystals to fabricate photocells used in the readout of various scintillators. The optical spectral response and efficiency of these photocells were measured and will be reported. Preliminary nuclear response from an HgI2 photocell that was optically matched to a Ce3+:LaBr3 scintillator will also be presented and discussed. Further improvements will be sought by optimizing the transparent contact technology.
