Abstract:
The plasma panel sensor (PPS) is a novel variant of micropattern gas detectors inspired by many operational and fabrication principles common to plasma display panels used in television displays. The PPS is comprised of an array of small plasma discharge gas cells. The panel is assembled from non reactive materials such as glass substrates, metal electrodes and mostly inert gas mixtures enclosed in a hermetically sealed panel.

The detection of ionizing radiation gives a fast signal, high granularity and spatial resolution (pixel can potentially be less than 100 um). Prototype detectors have been deployed in test beams (protons and muons) and lab tested with beta sources and CR muons. The results of these various tests are presented.
