MicroMegas detector
open-in-new
<p>The MicroMegas detector (Micro-Mesh Gaseous Structure) is a gaseous <a href="/facts/Particle_detector/rYj0qKtA">particle detector</a> and an advancement of the <a href="/facts/Wire_chamber/BKstxtE9">wire chamber</a>. Invented in 1996 by <a href="/facts/Georges_Charpak/jFRLcczW">Georges Charpak</a> and Ioannis Giomataris, Micromegas detectors are mainly used in experimental physics, in particular in <a href="/facts/Particle_physics/YgIuyj2t">particle physics</a>, <a href="/facts/Nuclear_physics/fzQbt1aF">nuclear physics</a> and <a href="/facts/Astrophysics/krFPRWLA">astrophysics</a> for the detection of <a href="/facts/Ionisation/W13Ceavd">ionizing</a> particles. </p> <p>Micromegas detectors are used to detect passing charged particles and obtain properties such as <a href="/facts/Position_(vector)/Tpk5d9f2">position</a>, arrival time and <a href="/facts/Momentum/TTkGv5eY">momentum</a>. The advantage of the Micromegas technology a high <a href="/facts/Gain_(electronics)/CWbehg27">gain</a> of 104 while operating with small response times in the order of 100 ns. This is realized by dividing the gas chamber with a microscopic mesh, which makes the Micromegas detector a <a href="/facts/Micropattern_gaseous_detector/cnmNxxUr">micropattern gaseous detector</a>. In order to minimize the perturbation on the impinging particle, the detector is just a few millimeters thick. </p>
