Abstract

X-ray detector that includes: A gaseous medium of the type characterized in that it is substantially opaque to electromagnetic radiation corresponding to the frequencies of the x-rays; A plurality of substantially planar anodes disposed in said gaseous medium; A plurality of flat cathodes disposed in said gaseous medium, each of said cathodes being located approximately at the same distance between two of said anodes; y Means for applying an electric potential of direct current between said cathodes and said anodes.
