粒子物理学的发现在很大程度上依赖于辐射探测器技术的平行进步。探测器仪器概念的真正创新出现在1968年，开发了一种可用于大量传感元件的完全并行读取器--多丝正比室(MWPC)，这为Georges Charpak赢得了1992年的诺贝尔物理学奖。这项发明使粒子检测发生了革命性的变化，粒子检测从光学读出设备(云室、乳胶室或气泡室)进入了电子时代。在过去的二十年里，光刻、微电子学和印刷电路板(PCB)技术的进步引发了气体探测器领域从导线结构到微图案气体探测器(MPGD)概念的重大转变。优秀的空间和时间分辨率、高速率能力、低质量、大有效区域和辐射硬度使其成为在研究前沿应对未来探测器挑战的宝贵工具。这种新型微图形器件的设计似乎适合于工业生产。将MPGD直接耦合到CMOS像素读取器的新型设备就像一个“电子气泡室”，允许以3D方式记录空间点和轨迹。2008年，欧洲核子研究中心建立了RD51合作，以进一步推动MPGDS和相关电子读出系统的技术开发，用于基础和应用研究。本审查概述了最先进的MPGD技术，并总结了在RD51协作框架内正在进行的活动。
Discoveries in particle physics vitally depend on parallel advances in radiation-detector technologies. A true innovation in detector instrumentation concepts came in 1968, with the development of a fully parallel readout for a large array of sensing elements - the Multi-Wire Proportional Chamber (MWPC), which earned Georges Charpak a Nobel Prize in Physics in 1992. This invention revolutionized particle detection which moved from optical-readout devices (cloud chamber, emulsion or bubble chambers) to the electronics era. Over the past two decades advances in photo-lithography, microelectronics and printed-circuit board (PCB) techniques triggered a major transition in the field of gas detectors from wire structures to the Micro-Pattern Gas Detector (MPGD) concepts. The excellent spatial and time resolution, high rate capability, low mass, large active areas, and radiation hardness make them an invaluable tool to confront future detector challenges at the frontiers of research. The design of the new micro-pattern devices appears suitable for industrial production. Novel devices where MPGDs are directly coupled to the CMOS pixel readout serve as an "electronic bubble chamber" allowing to record space points and tracks in 3D. In 2008, the RD51 collaboration at CERN has been established to further advance technological developments of MPGDs and associated electronic-readout systems, for applications in basic and applied research. This review provides an overview of the state-of-the-art of the MPGD technologies and summarizes ongoing activities within the framework of the RD51 collaboration.
