DEFINITION

Classification: 313/606

Electrode spacing related to mean free path length:

(under subclass 605) Subject matter wherein at least a portion of the electrode is spaced a distance from a portion of another electrode less than the mean free path spacing.

(1) Note. The spacing may be for the purpose of restricting current flow from one electrode or may be for the purpose of insulating one portion of an electrode from a portion of another electrode even though other portions of the electrodes are spaced a distance which permits ionization between such portions.

598, for a gas or vapor discharge device having a grid like or apertured electrode interposed in the discharge path between two discharge electrodes, the distance between the discharge electrodes being less than the means free path length.

620, for a gas or vapor discharge device having the spacing between electrodes cited as being a specific distance or a range of distances or being based upon the gas or vapor pressure or the operating electrical power.

621, for a gas or vapor discharge device having the electrodes spaced from each other in terms of a geometrical relationship.
