Development of a plasma panel radiation detector

Abstract

This article reports on the development and experimental results of commercial plasma display panels adapted for their potential use as micropattern gas radiation detectors. The plasma panel sensor (PPS) design and materials include glass substrates, metal electrodes and inert gas mixtures which provide a physically robust, hermetically-sealed device. Plasma display panels used as detectors were tested with cosmic ray muons, beta rays and gamma rays, protons, and thermal neutrons. The results demonstrated rise times and time resolution of a few nanoseconds, as well as sub-millimeter spatial resolution compatible with the pixel pitch.

Proton Radiography With Timepix Based Time Projection Chambers

“…Proton radiography and proton CT are being developed by a number of collaborations and groups; Loma Linda & Santa Cruz [6], the Italian TERA [7] and PRIMA [8] collaborations, and a number of other groups [9]- [12]. An overview of many initiatives is given in [13].…”

Operation and performance of microhexcavity pixel detector in gas discharge and avalanche mode

“…The µHex is under development as a scalable, fast timing (ns) and ultimately, sealed gas-hermetic tracking detector with high rate (> 100KHz/cm 2 ) capability. Derived from the earlier plasma panel detector [1] and microcavity detectors [2], they are fabricated as 16 × 16 pixel arrays of 2 mm edge-to-edge, 1 mm deep hexagonal cells embedded in a thin 1.4 mm glass-ceramic substrate. Cover plates can be glass or glassceramic, 300 µm thick.…”

Performance of a First Microhexcavity Plasma Panel Detector with Muons

“…Each pixel functions as an electrically and optically isolated detection unit. Detectors with this closed-cell architecture as well as open-cell architecture devices have been under development for several years [1], [2]. The response of the µHex to low-energy β sources and efficiency measurements with cosmic ray muons are reported here.…”
