Micro Megas Detector
The “Micromegas “ (Micro-MEsh Gaseous Structure) detector is a gaseous particle detector coming from the development of wire chamber. Invented in 1992 by Georges Charpak and Ioannis Giomataris, the Micromegas detectors are mainly used in experimental physics, in particular in particle physics, nuclear physics and astrophysics for the detection of ionising particles.
The Micromegas are light detectors in order to minimize the perturbation on the impinging particle. From their small amplification gap, they have fast signals in the order of 100 nanoseconds. They are precise detectors with a spatial resolution below one hundred of micrometer. Nowadays, the use of the Micromegas technology is growing over the different fields of experimental physics.
