    Abstract: A device for detecting impurities in a noble gas includes a detection chamber and a source of pulsed ultraviolet light. The pulse of the ultraviolet light is transferred into the detection chamber and onto a photocathode, thereby emitting a cloud of free electrons into the noble gas within the detection chamber. The cloud of electrons is attracted to the opposite end of the detection chamber by a high positive voltage potential at that end and focused onto a sensing anode. If there are impurities in the noble gas, some or all of the electrons within the cloud will bond with the impurity molecules and not reach the sensing anode. Therefore, measuring a lower signal at the sensing anode indicates a higher level of impurities while sensing a higher signal indicates fewer impurities. Impurities in the range of one part per billion can be measured by this device.

    Abstract: An in-line water monitoring system for the detection of the accidental or intentional introduction of potentially harmful substances. The automated system comprises a water pressure driven concentration unit that filters drinking water through a hollow-fiber filter. Material collected on the filter is backflushed into a collection vessel by passing a sterile solution through the filter in the reverse direction. An electronic signal at the end of the backflush sequence triggers a sensor such as an array biosensor to begin processing and analyzing the sample. The array biosensor houses a slide prepared with antibodies to the test organism. The array biosensor is programmed to automatically run sample and detection reagents over the slide, analyze the resulting pattern for positive and negative data, and report the results.

    Abstract: A chemical agent detector utilizing surface acoustic wave (SAW) sensors for detecting the presence of a multitude of chemical agents by sampling ambient air is provided. A pressure-differential manifold having an air intake port, an exhaust port, a valve and a pump is used to draw the ambient air into the manifold to be tested. A plurality of SAW sensors mounted on sensor driver boards which are in turn mounted on the manifold come into contact with the ambient air sample. Each SAW sensor is coated with a substance that has an affinity for detecting a particular chemical agent. Each SAW sensor driver board generates a continuous RF signal which emits a frequency shift if a particular chemical agent is detected. A power cycler module turns each sensor driver board on and off such that only one sensor driver board is powered-on at a given point in time. An RF multiplexor receives the continuous RF signals generated by the sensor driver boards and outputs one of the RF signals to a microprocessor based upon a timing signal generated by the microprocessor. The microprocessor interprets the frequency shift as the detection of a chemical agent and provides an alarm that a particular chemical agent has been detected.

    Abstract: A neutron detector is provided which is able to measure thermal neutron radiation within a gap filled with a substance that permits scintillation in the absorption of thermal neutron radiation, the gap being formed between at least a first and second spaced apart photodetector working in electrical coincidence. The substance disposed within the gap can be either a gas, liquid or solid. In the case of a gas, a shell is used so that the gas can be retained and kept under pressure. The neutron detector is able to differentiate between gamma radiation and neutron energy. An alternate embodiment of the novel detector includes a device which employs a plurality of detectors surrounding a moderator which can be used to measure both thermal and high energy neutrons.

    Abstract: An ionization chamber is provided for the detection of nuclear radiation. The chamber is a vessel which acts as a cathode wherein at least one anode is disposed within the chamber and off-set from a center axis of the chamber. The chamber can be made from variety of shapes but is cylindrical in the preferred embodiment. The device contains two anodes in the preferred embodiment which are both off-set from the center axis. One anode collects the free floating electrons which are produced in response to particle ionization and therefore has a collected charge applied thereto. The second anode has the charge induced by immobile ions. The induced charge is subtracted from the collected charge thereby providing an improved resolution for the ionization chamber which translates into a more accurate result. In the preferred embodiment, a pressurized noble gas, such as xenon, is used. In some special geometries of the chamber, one of the anodes becomes part of the cathode and the charge induced by immobile ions becomes negligibly low. Thus the subtraction of the induced charge is not required.
