Abstract:
1. A position-sensitive neutron counting radiation detector comprising: a first substrate; a second substrate generally parallel to said first substrate and forming a gap with said first substrate; a gas mixture of at least two components contained within said gap; at least one neutron conversion layer coupled to at least one of said substrates; at least one first electrode coupled to one of said substrates; at least one second electrode electrically coupled to said first electrode; a first impedance coupled to said first electrode; a power supply coupled to at least one of said electrodes; a first discharge event detector coupled to at least one of said electrodes for detecting a gas discharge counting event in said electrode; a plurality of pixels defined by said electrodes, each pixel capable of outputting a gas discharge counting event pulse upon interaction with ionizing particle radiation received from said neutron conversion layer, wherein each gas discharge pulse is counted as having an approximately equal value; and circuitry for detecting if a gas discharge counting event pulse is output from the pixels, and for counting each such gas discharge pulse as an individual event.
