Abstract:
An ultraviolet sensitive gaseous discharge detector has essentially uniform angular sensitivity in a plane perpendicular to the axis of the detector tube and in the plane of the detector tube axis. The cathode of the detector is in the form of a thin sputtered layer of metal adhering to the inner wall of the envelope of the detector.
Abstract:
An ultraviolet sensitive gaseous discharge detector has uniform sensitivity over a broad viewing angle. The cathode of the detector has an essentially circular cross-section while the anode has an elongated cross-section. The anode is aligned in a common plane with the cathode with the elongated surfaces of the anode being aligned essentially parallel to the common plane of the electrodes.
Abstract:
A radiation counting tube includes a plurality of longitudinally disposed cathode sections of different sensitivities coaxially surrounding a common anode to permit simplified measurement of a wide range of radiation on a single meter scale without switching.
