Current balance at the surface of a cold cathode

Physical Review Letters, 1987
Recent experimental and theoretical developments, including an electric field diagnostic based on optogalvanic detection of Rydberg atoms, an analytic treatment of ion transport in the cathode fall, and a null collision Monte Carlo technique, are combined to determine the current balance at the surface of a cold cathode in a He glow discharge.

A Cold-Cathode Arc-Discharge Tube

Transactions of the American Institute of Electrical Engineers, 1936
A grid-controlled arc-discharge tube which requires neither power nor time for heating the cathode, but in which a discharge of several hundred amperes is controlled by an extremely small amount of power in the grid circuit, is described in this paper.

Advances in cold cathode physics and technology

Proceedings of the IEEE, 1999
We review recent progress in the physics and technology of cold cathode electron emitters. The characteristics of emission from field emitter arrays, photocathodes, and ferroelectrics are presented, together with a summary of the understanding of the physics involved.

A Cold Cathode Rectifier

Journal of Applied Physics, 1947
A cold cathode rectifier is described in which corona discharge is used at atmospheric and higher pressures in hydrogen and nitrogen free of electron-attaching impurities. This kind of tube has advantages where the current demands upon a rectifier are small.

Compact cold-cathode electron buncher

IEEE Conference Record - Abstracts. 2002 IEEE International Conference on Plasma Science (Cat. No.02CH37340), 2003
Summary form only given, as follows. We are developing a compact high-frequency electron buncher for applications in the next generation of microwave tubes and electron accelerators. This electron buncher uses a conventional Pierce-type electron gun with a gated field-emitter-array cathode for the production of short, 10 kV, 100 mA electron bunches ...

Cold Cathode Rectification

Proceedings of the IRE, 1929
Asymmetric conductivity in a gas between two electrodes can be accomplished without the use of a hot cathode, if the relative areas of the electrodes are widely different. This paper presents the results of an investigation of the discharge phenomena and asymmetric conductivity in a cold cathode rectifier tube containing two anodes and one cathode ...

A cold cathode lighting element prototype

Ultramicroscopy, 2003
In this study, we present a prototype of lighting element in which a carbon-containing field emission material is used as the cathode. The operating characteristics, i.e. current-voltage characteristics, current stability, luminance and lifetime of the lighting element are tested.

Cathodic etching in a penning cold cathode discharge

Vacuum, 1959
Abstract An apparatus for cathodic etching using a Penning cold cathode discharge is described. One of the twin cathodes is the specimen to be etched whilst the other is made of aluminium. The cathodes are water cooled so that metals of either low melting point or low sputtering rate will not overheat during the cathodic etching.
