Multi-Element Mercuric Iodide Detector Systems for X-Ray and Gamma-Ray Imaging

  • Bradley E. Patt (a1)

Abstract

The advancement of room-temperature mercuric iodide detector technology to the point of spectroscopy-grade energy resolution coupled with the advancement in long-term stability and the high efficiency of these detectors now make it's use in large scale array systems for x- and gamma-ray imaging applications viable. Camera design criterion differ depending upon the application. A HgI2 gamma-ray camera developed at EG&G Energy Measurements has been used for imaging with various apertures, and the energy dispersive imaging aspects have been examined. Concepts for applications such as medical diagnostic imaging and a satellite based telescopes for x- and gamma-ray mapping have been objectified.
