Plasma panel-based radiation detectors

The plasma panel sensor (PPS) is a gaseous micropatternradiation detector under current development. It has many operational and fabrication principles common to plasma displaypanels. It comprises a dense matrix of small, gas plasma discharge cells within a hermetically sealedpanel. As in plasma displaypanels, it uses nonreactive, intrinsically radiation-hard materials such as glass substrates, refractory metalelectrodes, and mostly inert gas mixtures. We are developing these devices primarily as thin, low-mass detectors with gas gaps from a few hundred microns to a few millimeters. The PPS is a high gain, inherently digital device with the potential for fast response times, fine position resolution (<50-mm RMS) and low cost. In this paper, we report on prototype PPS experimental results in detecting betas, protons, and cosmic muons, and we extrapolate on the PPS potential for applications including the detection of alphas, heavy ions at low-to-medium energy, thermal neutrons, and X-rays.
