  • He-3 neutron proportional counter with internal leakage detection and related method
    Patent number: 7456411
    Abstract: A radiation detector includes a pressure-tight housing having a peripheral, cylindrically-shaped wall and opposite end closures. An electrode wire extends through a center of the housing, spaced from the cylindrically-shaped wall. A pressurized detector gas fills the housing, and circuit connections to the electrode wire and the housing permits application of an electric potential thereto. The electrode wire is composed of a material providing a source of alpha particles for ionizing the gas within the housing, generating an alpha peak on the output spectrum distinct from the peak generated by incident neutrons. A related method is also disclosed.
    Type: Grant

  • Radiation detector employing amorphous material
    Publication number: 20080283762
    Abstract: A radiation detector is provided having an anode wire formed of an amorphous metal alloy. In one embodiment the radiation detector comprises a cathode assembly. The cathode assembly includes a main portion, a first end and a second end, where the first end opposes the second end. The cathode assembly also includes a radiation interacting material. An anode extends within the cathode assembly from the first end to the second end, and the anode is comprised of an amorphous metal alloy.
