Abstract
A position-sensitive ionizing-particle radiation counting detector includes a first substrate and a second substrate generally parallel to the first substrate and forming a gap with the first substrate, with a discharge gas contained within the gap. The detector includes a first electrode electrically coupled to the second substrate, and a second electrode electrically coupled to the first electrode and defining at least one pixel with the first electrode. The detector further includes an open dielectric structure pattern layered over one of the first or second electrodes and a current-limiting quench resistor coupled in series to one of the first or second electrodes. The detector further includes a power supply coupled to one of the first or second electrodes and a first discharge event detector circuitry coupled to the one of the first or second electrodes for detecting a gas discharge counting event in the electrode.
