Abstract: A radiation measurement apparatus for measuring radiation includes a first and second Geiger-Muller counter tubes and a radiation-direction calculating unit. The first Geiger-Muller counter tube seals an electrode within a circular pipe-shaped enclosing tube that extends in a straight line. The first Geiger-Muller counter tube is arranged along a first direction. The second Geiger-Muller counter tube seals an electrode within a circular pipe-shaped enclosing tube that extends in a straight line. The second Geiger-Muller counter tube is arranged in a second direction intersecting with the first direction. The radiation-direction calculating unit is configured to compare a first detection signal and a second detection signal with one another to calculate a direction of radiation to be emitted from the sample. The first detection signal is output from the electrode of the first Geiger-Muller counter tube. The second detection signal is output from the electrode of the second Geiger-Muller counter tube.

Abstract: Anodes for proportional radiation counters and a process of making the anodes is provided. The nano-sized anodes when present within an anode array provide: significantly higher detection efficiencies due to the inherently higher electric field, are amenable to miniaturization, have low power requirements, and exhibit a small electromagnetic field signal. The nano-sized anodes with the incorporation of neutron absorbing elements (e.g., 10B) allow the use of neutron detectors that do not use 3He.

Abstract: A radiation detector system and method that significantly reduces the cost of conventionally constructed radiation detectors is disclosed. The disclosed system generally comprises an injection molded detector body incorporating plastic material with embedded feed-thrus that are encapsulated within the detector body. This detector body is mated to a detector window assembly using a gasket or other means of sealing to inhibit gas leakage. The mating methodology between the detector body and the detector window assembly is by means of plastic snap-on tabs in these structures that permit semi-permanent mating while also allowing the structures to be easily disassembled for repair and maintenance. The present invention system/method permits a significant hardware cost reduction as compared to conventional prior art radiation detector construction methodologies.

Abstract: The readout electrode assembly of an avalanche particle detector can be effectively protected against sparks and discharges by means of a plurality of resistor pads formed in a dielectric cover layer above the readout pads. The resistor pads may either be connected directly to the readout pads, or may be coupled capacitively by means of a charge spreading pad embedded into the dielectric cover layer and spatially separated from the readout pads. The charge spreading pad allows the distribution of charges to neighboring readout pads, and may hence increase the spatial resolution of the detector device.
