Abstract

The fabrication of polycrystalline HgI₂ thick film detectors using the hot wall physical vapor deposition, method is described. The X-ray response of these detectors to a radiological X-ray generator of 60 kVp has been studied using the current integration mode. The response expressed in (mu) A, the dark current expressed in pA/cm² and sensitivity expressed in (mu) C/R(DOT)cm² are given for these detectors for several thickness and grain sizes. The optimal sensitivity is compared with published data on the response to X-rays by polycrystalline PbI₂ and A-Se detectors.
