HPGe detector with LN2 cryostat Source: canberra.com<\/figcaption><\/figure>\nBut if a\u00a0perfect energy resolution<\/strong> is required, we must use a germanium-based detector<\/strong>, such as the\u00a0HPGe detector<\/strong>. Germanium-based semiconductor detectors are most commonly used where a very good energy resolution is required, especially for gamma and<\/strong>\u00a0x-ray spectroscopy<\/strong>. In gamma spectroscopy, germanium is preferred due to its atomic number being much higher than silicon, increasing the probability of gamma-ray interaction. Mor over, germanium has lower average energy necessary to create an electron-hole pair, which is 3.6 eV for silicon and 2.9 eV for germanium. This also provides the latter with a better resolution in energy. The FWHM (full width at half maximum) for germanium detectors is an energy function. For a 1.3 MeV photon, the FWHM is 2.1 keV, which is very low.<\/p>\n<\/div><\/div>\n<\/span>References:<\/div>\n
