Presentation Transcript

  1. Outline of UM Presentation • Overview of intended PPS attributes • Motivation for development • Proof-of-principle experiments & Establishing basic attributes • Laboratory setups and prototype testing • Off shelf PDPs • New, custom PDP panels • Facilities: Test vessel, gas mixer, DAQ, sources, test beams, etc • Basic physics: avalanche, streamer, discharge • Lab test conducted (highlights) • Hit rates with source and background • Signals, pixel capacitance, HV, Pashen potential etc • Measurements with sources: • Spatial measurements • Saturation measurement • Cosmic Muons • Test Beam

  2. PPS Overview • Development of new type of charged particle, gaseous radiation detector • Based on Plasma Display Panel (PDP) technology used in plasma-TVs. • A Plasma Panel Sensor (PPS) is a micro-pattern radiation detector • Inherit many operational and fabrication principles common to PDPs • Comprised of a dense array of small, gas plasma discharge cells. • Cells or pixels are enclosed in hermetically-sealed glass panel. • Uses uses non-reactive, intrinsically radiation-hard materials: glass substrates, refractory metal electrodes, inert gas mixtures. • Anticipate eventual device fabrication as very thin, low-mass detectors • PPS should be a high gain, inherently digital device • Potential for very fast response times & • High granularity & Intended position resolution (< 100 µm) • Low cost
