DEFINITION

Classification: 313/359.1

WITH POSITIVE OR NEGATIVE ION ACCELERATION:

(under the class definition) Subject matter which are provided with means for generation positive or negative ions and which are provided with means to accelerate the ions.

(1) Note. Many of the devices in this subclass are provided with means such as an ion transparent window for allowing ions to emerge from the envelope of the discharge device.

SEE OR SEARCH THIS CLASS, SUBCLASS:

62, for cyclotrons.

230, for discharge devices which are provided with an evacuated envelope and which have means for generating positive ions.

231.01+, for discharge devices with means for supplying fluent material to the discharge space.

364+, for cathode-ray tubes which may include means for controlling or deflecting an electron beam.

567, for discharge devices which include an envelope and a confined atmosphere of gas or vapor and which necessarily generate positive ions in their operation. 588, for gas or vapor-type discharge devices which are provided with an envelope having two portions, one of the

portions containing electrodes designed to generate an ionizing discharge, the ionizing discharge supplying electrons to an electrode in the second portion of the device; the second portion being designed to operate with an electronic discharge. The two portions of the envelope may be separated by a barrier which is permeable to ions but impermeable to the gas or vapor in the first envelope portions.
