    Abstract: A method of and system for analyzing ion mobility of a sample. The sample is received by an ionization chamber, which ionizes molecules of the sample. The ionized sample is received from the ionization chamber by a drift tube coupled to the ionization chamber and propelled along a length of the drift tube in a first direction away from the ionization chamber by an electric field gradient of the drift tube. A magnitude of the electric field gradient is in view of an atmospheric pressure measurement. A drift gas is propelled through the drift tube in a second direction opposite the first direction such that different types of ionized molecules travel through the drift tube at different rates. An arrival time of each of the different types of molecules at a detector located at a second end of the drift tube opposite the first end is detected.

    Abstract: A Geiger-Mueller ("GM") tube containing a noble gas mixture of about 98-99.9% Ne and the remainder Ar, and in addition containing from 2-5% ethylene as the quench gas, provides high stability and high count rates in the temperature range from about -100.degree. C. to about 200.degree. C. When this GM tube is provided with a sleeve-and-screen liner in electrical contact with an outer cathode, the tube exhibits exceptional sensitivity. The sleeve may be a continuous deposit of a heavy metal having an atomic number from about 73 to about 83, deposited on the inner surface of the cathode tube, or the sleeve may be a foil liner of tungsten or tantalum. The screen is woven of metal wire on which is deposited a heavy metal.

    Abstract: A direct ion storage (DIS) radiation detector or dosimeter has a design that is easy and low cost to manufacture using semiconductor processing techniques. The detectors include internal communications interfaces so they are easy to read. Different interfaces, including wired, e.g. USB ports, and wireless interfaces, may be used, so that the dosimeters may be read over the internet. The detectors can thus be deployed or used in a variety of detection systems and screening methods, including periodic or single time screening of people, objects, or containers at a location by means of affixed dosimeters; screening of objects, containers or people at a series of locations by means of affixed dosimeters, and surveillance of an area by monitoring moving dosimeters affixed to people or vehicles.

    Abstract: A wire chamber or proportional counter device, such as Geiger-Mueller tube or drift chamber, improved with a gas mixture providing a stable drift velocity while eliminating wire aging caused by prior art gas mixtures. The new gas mixture is comprised of equal parts argon and ethane gas and having approximately 0.25% isopropyl alcohol vapor.

    Abstract: A muon detector includes: a chamber having a maximum cross-sectional dimension of 30 cm or less; a gas sealed inside the chamber ionized by the passage of atmospheric muons to form ions in the chamber; a cathode in the chamber at a first position; an anode in the chamber displaced from the first position, the anode including a mesh of wires; a micropattern gaseous detector arranged between the cathode and the anode and proximate to the anode and configured to receive the ions formed in the chamber between the anode and the cathode and generate electrons in response to each ion sufficient to generate a current in one or more of the mesh wires of the anode; and readout electronics in electrical communication with the anode to detect signals in response to the current generated in the mesh wires.
