Abstract
A position-sensitive radiation counting detector includes a first and a second substrate. A gas is contained within the gap between the substrates. A photocathode layer is coupled to the first substrate and faces the second substrate. A first electrode is coupled to the second substrate and a second electrode is electrically coupled to the first electrode. A first impedance is coupled to the first electrode and a power supply is coupled to at least one electrode. A first discharge event detector is coupled to one of the electrodes for detecting a gas discharge event in the electrode. The radiation counting detector further includes a plurality of pixels, each capable of outputting a gas discharge counting event pulse upon interaction with radiation received from the photocathode. Each gas discharge pulse is counted as having an approximately equal value.
