Microhollow cathode discharges
By reducing the dimensions of hollow cathodes into the hundred micrometer range, stable, direct current, high ~atmospheric! pressure glow discharges in rare gases, rare gas–halide mixtures and in air could be generated. The electron energy distribution in these microdischarges is non-Maxwellian, with a pronounced high-energy tail. The high electron energy together with the high gas density, whi...
متن کاملCharacterization of microhollow cathode discharges
This work is devoted to the study of the electrical characteristics of microhollow cathode discharges (MHCD) at moderate to high pressure in argon and air for different geometries. High-pressure glow discharges can be operated in MHCD devices with μm electrode spacing. Experiments have been performed to determine the so-called Paschen curves, i.e. the dependence of the breakdown voltage on the ...

متن کاملFeatures and Operation of Hollow Cathode Lamps and Deuterium Lamps
This paper discusses the parameters which influence the operation of hollow cathode and deuterium lamps. Examples are given of how parameters can be selected in order to improve the quality of analytical results. Aspects of deuterium lamp operation for background correction are also covered.
متن کاملHollow Cathode Discharge Initiation and Fast Starting Cathode
Conditioning of the insert inside a hollow cathode is believed to be important to ensure reliable discharge initiation and subsequent cathode operation. The desorption of contaminates is reported from hollow cathodes as a function of heater power to quantify cathode conditioning characteristics and identify factors that might prevent the fast initiation of a discharge. In addition to conditioni...
