Abstract
A radiation detector comprises two electrode arrangements, each including a dielectric substrate and an electrically conducting layer formed on a first surface of respective dielectric substrate, wherein the electrodes are oriented such that the conducting layers are facing each other. A dielectric spacer is provided to hold the electrodes at a distance from each other to thereby define an inter-electrode space, which, during use, is filled with an ionizable gas. The electrodes are held at respective electric potentials to drift electrons released during ionization of the ionizable gas by external radiation towards one of the electrodes for detection. To suppress the occurrence of sparks in the inter-electrode space an electrically conducting layer is formed on a second surface of the dielectric substrate of either one of the electrodes, and, during use, held at a selected electric potential held at a selected electric potential to thereby reduce the risk for occurrence of sparks between the cathode and anode arrangements.
