    Abstract: the wavelength detector includes a diffusion element that diffuses the laser beam; a light collection optical system provided downstream from the diffusion element; a member, including an aperture, provided downstream from the light collection optical system; a discharge tube that is provided downstream from the member and that includes a cylindrical anode and a cylindrical cathode that each have a through-hole formed therein, and that is configured so that an electrical property between the anode and the cathode changes due to an opto-galvanic effect when a laser beam having a predetermined wavelength passes through the through-hole of the cathode in a state in which a DC voltage is applied to the anode; and a high-voltage DC power source. The discharge tube is disposed so that the laser beam that passes through the aperture passes through the through-hole of the cathode of the discharge tube without directly irradiating the cathode.

    Abstract: A detector system for performing at least one of transmitting and receiving electromagnetic radiation at a low-terahertz frequency. The detection of electromagnetic radiation at low-terahertz frequencies can be useful in the detection of various chemicals. Preferably a detector includes a microresonant structure that is caused to resonate by electromagnetic radiation at a low-terahertz frequency. The resonance is detected by detecting an altered path of a charged particle beam.

    Abstract: A microdischarge photodetector has a photocathode, an insulator and an anode. A cavity of limited size is disposed in the insulator and filled with gas. A voltage applied between the photocathode and the anode produces a plasma. Light incident on the photocathode having photon energies larger than about the work function produces photoelectrons are ejected from the photocathode and accelerated by the plasma electric field. The incident light is detected by detecting an increase in the plasma current or light emission from the plasma. The cavity may be flat or tapered and is designed to optimize detector performance.

    Abstract: A subatomic particle detector having a large number of equally spaced anode conductors arranged in a single plane opposite and parallel to a large cathode plate with the space between the anode conductors and cathode plate filled with liquid argon. A phototransistor is connected to each conductor for automatic readout of the detector by means of a laser beam that is scanned over each phototransistor.

    Abstract: An ultraviolet detector in which the electrode configuration is non-symmetrical in that one electrode operates permanently as the emitter and the other as the collector, at least one of the electrodes supported by the inner surface of the tube envelope and offering an expansive wide angle field of view for incoming ultraviolet radiation. The electrodes are DC biased to provide a high voltage difference therebetween, i.e., between cathode, or emitter, and anode or collector, the former responsive to each photon of ultraviolet energy incident from within the wide angle.

    Abstract: An apparatus is provided for detecting failures in nuclear fuel elements. Specific measurement of Krypton and Xenon as gaseous nuclear fission products is achieved by separating these elements from other coexisting radioactive elements and measuring the beta rays emitted from the Krypton and Xenon thus separated with a high counting efficiency. Separation is provided by passing the combined gases through separate columns filled with molecular sieve materials, or activated charcoal, in combination with a carrier Q-gas as used in a gas flow counter.
