    Abstract: An encapsulated planar cathode structure is formed for a vacuum tube. A multibeam cathode ray tube is obtained by heating in the CRT such a structure with a plurality of separated electron emissive layers to remove the encapsulation material. Positive photoresist technology is utilized: for obtaining delineated apertures on a planar metallization layer supported by an insulating substrate into which needle-shaped carbonate particles are deposited electrophoretically normal to the metallization; and for encapsulating the resultant cathodes.

    Abstract: An improved diode for forming an intense electron beam and propagating theeam. The diode includes a cathode having a bore, and a rod-shaped anode having a medial tapered section which extends, approximately coaxially, through the bore of the cathode. The anode tapers at or near the cathode and is formed from electrically conductive material. The cathode is made from a material which rapidly emits electrons during the early stage of an applied voltage pulse. The electrons strike the anode and form a plasma thereon. Sufficient anode current and the formation of sufficient anode plasma affect the magnetic and electric fields to pinch the electrons closer to each other and to force the electron beam to propagate along the anode and away from the cathode and voltage supply. The tapered section of the anode increases the velocity of the pinch and the density of the electron beam.

    Abstract: A series of discrete heating current pulses are passed through a line cathode so as to cause the cathode to emit electrons therefrom. Between each consecutive pair of pulses is a cooling period during which no heating current flows through the cathode. Current is extracted from the cathode during this cooling period. In a preferred embodiment for an image display device, the heating pulse duration is about 10 .mu.sec and the cooling period is about 50.mu.sec. In this scheme, the heating period corresponds roughly to the horizontal retrace time between line times of 50.mu.sec.
