Since their introduction by George Charpak in the late sixties, multi-wire gaseous detectors have matured with major implications in particle physics experiments; they have also been very successfully developed for their use in other fields: X-ray and medical imaging, UV and single photon detection, neutron and crystal diffraction studies etc. Their major limitation has been a modest rate capability. In the last decade several high rate micro-pattern position sensitive gas devices have been introduced with an inherently improved rate capability and localization accuracy. A state-of-the-art from the old to the new generation of gaseous detectors will be reviewed.
