  • Patent number: 9529099
    Abstract: A position-sensitive ionizing-radiation counting detector includes a first substrate and a second substrate, and a defined gas gap between the first substrate and the second substrate. The first and second substrates comprise dielectrics and a discharge gas is contained between the first and second substrate. A microcavity structure comprising microcavities is coupled to the second substrate. An anode electrode is coupled to the first substrate and a cathode electrode is coupled to the microcavity structure on the second substrate. The detector further includes pixels defined by a microcavity and an anode electrode coupled to a cathode electrode, and a resistor coupled to each of the cathode electrodes. Each pixel may output a gas discharge counting event pulse upon interaction with ionizing-radiation. The detector further includes a voltage bus coupled to each of the resistors and a power supply coupled to at least one of the electrodes.

  • Publication number: 20160349381
    Abstract: A position-sensitive ionizing-radiation counting detector includes a radiation detector gas chamber having at least one ultra-thin chamber window and an ultra-thin first substrate contained within the gas chamber. The detector further includes a second substrate generally parallel to and coupled to the first substrate and defining a gas gap between the first substrate and the second substrate. The detector further includes a discharge gas between the substrates and contained within the gas chamber, where the discharge gas is free to circulate within the gas chamber and between the first and second substrates at a given gas pressure. The detector further includes a first electrode coupled to one of the substrates and a second electrode electrically coupled to the first electrode. The detector further includes a first discharge event detector coupled to at least one of the electrodes for detecting a gas discharge counting event in the electrode.
