    The sound of a geiger counter. A Geiger counter (/ ˈ ɡ aɪ ɡ ər /, GY-gər; [1] also known as a Geiger–Müller counter or G-M counter) is an electronic instrument for detecting and measuring ionizing radiation with the use of Geiger–Müller tube.

  3. Microchannel plate detector - Wikipedia

    en.wikipedia.org/wiki/Microchannel_plate_detector

    A microchannel plate within a Finnigan MAT 900 sector mass spectrometer position-and-time-resolved-ion-counting (PATRIC) scanning array detector. An external voltage divider is used to apply 100 volts to the acceleration optics (for electron detection), each MCP, the gap between the MCPs, the backside of the last MCP, and the collector .

    The E-T secondary electron detector can be used in the SEM's back-scattered electron mode by either turning off the Faraday cage or by applying a negative voltage to the Faraday cage. However, better back-scattered electron images come from dedicated BSE detectors rather than from using the E–T detector as a BSE detector.
