Micro-Pattern Gas Detector-MPGD
The Micro-Pattern Gas Detector(MPGD) has very excellent properties, such as unprecedented spatial resolution, high rate capability, large sensitive area, optional stability and radiation hardness, so it is widely used in the fields of basic and applied research.
If we want to talk about the MPGD, we have to say something first about one scientist, named Georges Charpak, and his invention and development of detectors in high energy physics. Since 1959, he's been working at CERN, the European Laboratory for Particle Physics situated on the border of France and Switzerland. Charpak invented the Multiwire Proportional Chamber at CERN and this pioneering work was published in 1968(G. Charpak, et al., "The use of multiwire proportional chambers to select and localize charged particles", Nucl. Instr. Meth. 62(1968)202-226). Because his foundamental idea about the gaseous detector and his contributions for new detection technology in the high energy physics, he was rewarded the 1992 Nobel Prize in Physics.
From then on, based on his original invention, various types of particle detectors have been invented and developed, such as GEM(Gas Electron Multiplieri, F. Sauli, NIMA386(1997)531-534), Micromegas(Micro-Mesh Gaseous Structure, by Y. Giomataris et al., NIMA376(1996)29-35), and other more recently micro-pattern detector(For detail, please refer to the RD51 webpage).
