研究了具有小像素阳极和厚度为4-5 mm的碘化汞γ射线谱仪。采用三维位置敏感单极性电荷传感技术，在4 mm厚的探测器上获得了2.9%FWHM的能量分辨率。报道了在两个探测器上观察到的典型现象，并讨论了它们的特性。结果表明，如果采用三维位置敏感的单极性电荷传感方法，利用市售的HgI 2材料可以构建高效的γ射线谱仪。
HgI2gamma-ray spectrometers having small pixel anodes and a thickness of 4–5 mm have been investigated. An energy resolution of 2.9% FWHM was obtained on a 4 mm thick detector using the three-dimensional position sensitive single polarity charge sensing technique. Typical phenomena observed on two detectors are reported and their characteristics are discussed. The results indicate that it is possible to construct efficient gamma-ray spectrometers using commercially available HgI2materials if the three-dimensional position sensitive single polarity charge sensing method is implemented.
