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.

Microtips cathode for ignition of cold cathode gauges

Vacuum, 1997
A novel device used for ignition of Penning gauges is described. It is based on electron emission by a field effect microtips cathode. The complete reliability of the device is demonstrated.

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.

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.

Cold-cathode counting circuits

Transactions of the American Institute of Electrical Engineers, Part I: Communication and Electronics, 1955
IN RECENT years, considerable emphasis has been placed on high-speed counting devices for use in electronic computers and designed to operate at pulse rates of the order of 100 kc, and higher. These of necessity involved hot-cathode electron tubes.

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.
