The microstrip gas chamber [PDF]
Nuclear Physics B - Proceedings Supplements, 1991 Abstract We describe the operating principles of the microstrip gas chamber and the main results of measurements realized with several prototype devices in the detection of X-rays and charged particles. Detectors with 3, 5 and 10 μm anode widths and 125 or 200μm pitch have been successfully tested. A gas gain of 10 4 and an energy resolution of 12.2%
