2. Micropattern gaseous detector - Wikipedia

   en.wikipedia.org/wiki/Micropattern_gaseous_detector

   Micropattern gaseous detectors (MPGDs) are a group of gaseous ionization detectors consisting of microelectronic structures with sub-millimeter distances between anode and cathode electrodes. When interacting with the gaseous medium of the detector, particles of ionizing radiation create electrons and ions that are subsequently drifted apart by ...

3. Gaseous detection device - Wikipedia

   en.wikipedia.org/wiki/Gaseous_detection_device

   The gaseous detection device (GDD) is a method and apparatus for the detection of signals in the gaseous environment of an environmental scanning electron microscope (ESEM) and all scanned beam type of instruments that allow a minimum gas pressure for the detector to operate.

4. MicroMegas detector - Wikipedia

   en.wikipedia.org/wiki/Micromegas_detector

   The MicroMegas detector (Micro-Mesh Gaseous Structure) is a gaseous particle detector and an advancement of the wire chamber.Invented in 1996 by Georges Charpak and Ioannis Giomataris, [1] Micromegas detectors are mainly used in experimental physics, in particular in particle physics, nuclear physics and astrophysics for the detection of ionizing particles.

5. Gaseous ionization detector - Wikipedia

   The disadvantages are that anode wires are delicate and can lose efficiency in gas flow detectors due to deposition, the efficiency and operation affected by ingress of oxygen into fill gas, and measurement windows easily damaged in large area detectors. Micropattern gaseous detectors (MPGDs) are high granularity gaseous detectors with sub ...

   ESEM gaseous detection device (GDD)-principle Efficiency characteristics of gaseous detection device in ESEM Main article: Gaseous detection device In a simple form, the gaseous detection device (GDD) employs an electrode with a voltage up to several hundred volts to collect the secondary electrons in the ESEM.

7. Gas detector - Wikipedia

   en.wikipedia.org/wiki/Gas_detector

   A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as ...
