detector Everhart–Thornley detector CHMO:0002532 2009-10-16T01:42:51Z ETD detector A detector used in scanning electron microscopy experiments to detect secondary electrons. The detector consists of a scintillator inside a Faraday cage inside the specimen chamber of the microscope. A low positive voltage is applied to the Faraday cage to attract the relatively low-energy (<50 eV) secondary electrons.
