Abstract: A location- or positionally-sensitive proportional counter tube of high resolution having a trough-shaped cathode in a counting chamber. A resiliently elastic wire forming the anode extends longitudinally through the counting chamber. Suitable fastening arrangements engage the ends of the wire so as to mount the wire equidistantly from the side walls of the cathode trough and in electrical communication with the input resistor of a preamplifier. The counting chamber is an openable high-pressure chamber with inlet and outlet apertures for a pressurized counter tube gas.

Abstract: A curved location- or positionally-sensitive proportional counter tube having a trough-shaped cathode in a counting chamber. A curved resiliently elastic wire forming the anode extends longitudinally through the curved counting chamber in conformance with the curvature of the latter. Suitable fastening arrangements engage the ends of the wire so as to mount the wire in asymmetrical relationship to a counter tube window and equidistantly from the side walls of the cathode trough.
