Abstract
Devices and methods for detecting radiation are described. A detector for detecting radiation comprises a housing containing an ionisable gas, an array of anode wires extending substantially in a first plane, and arranged to be held at a first potential for attracting electrons, and at least one cathode wire spaced in a predetermined relationship from the anode wires, arranged to be held at a second, lower potential. The detector further comprises at least one additional electrode positioned adjacent a periphery of the array of anode wires, and arranged to be held at a third potential, greater than the second potential. A window for a radiation detector is described and comprising a housing containing an ionisable gas is also described. The window comprises a layer formed of an electrically conductive material forming an electrode, a layer formed of a plastic, arranged to support the layer formed of electrically conductive material, and a layer of gas impermeable material.
