This paper describes the use of microdischarges as transducing elements in sensors and detectors. Chemical and physical sensing of gases, chemical sensing of liquids, and radiation detection are described. These applications are explored from the perspective of their use in portable microsystems, with emphasis on compactness, power consumption, the ability to operate at or near atmospheric pressure (to reduce pumping challenges), and the ability to operate in an air ambient (to reduce the need for reservoirs of carrier gases). Manufacturing methods and performance results are described for selected examples. [Figure not available: see fulltext.]

    We have detected and measured for the first time the amplification of a narrow-band radiation (second harmonic of an argon ion laser, λ = 244 nm) propagating through a dc gas-discharge plasma in hydrogen at a pressure of 0.5-1.0 Torr. An attempt is made at explaining this phenomenon.

    The placement of lost alpha particle detectors in ITER has been studied using a full gyro-motion orbit calculation code, in which the orbit is located in the plasma side of the first wall boundary. Detection rates are likely to be low with the detector is placed inside the blanket. Tilting the...
