Abstract: The purpose of the off-axis electron gun is to generate a beam of electrons and to deflect the beam onto the axis of a device which utilizes the beam. The off-axis electron gun includes an arcuate wire electron emitting source subtending an azimuthal angle of up to 125.degree., a non-intercepting azimuthally asymmetric focussing and deflecting electrode located at and around the electron source, and an anode plate with a beam exit hole. The non-intercepting electrode has an arcuate slot subtending a predetermined angle at a predetermined radius from the beam axis in which the arcuate wire electron source is mounted in electrical isolation from the electrode. The deflecting section of the electrode is azimuthally asymmetric in shape such that when selected voltages are applied between the wire source, the focussing and deflecting sections of the non-intercepting electrode and the anode, an electric field is produced which directs the electrons towards the axis, focusses the beam and deflects it onto the axis.

Abstract: An electron gun assembly includes a plurality of cathode assemblies and a plurality of spaced successive electrodes mounted on at least two electrically-insulating support rods. At least one of the electrodes comprises a deep-drawn substantially rectangular cup-shaped member having a base portion, a supporting flange portion, including a plurality of attachment tabs, and a sidewall extending between said base portion and said supporting flange. The sidewall includes a substantially wedge-shaped shoulder on each of the opposed side thereof that projects outwardly at an acute angle of about 45 degrees from the sidewall. The shoulders extend into the supporting flange adjacent to the attachment tabs. The shoulders form a gusset on each of the opposed sides of the cup-shaped member thereby increasing the structural rigidity of the member.

Abstract: A method and apparatus for merging electrons and ions in a neutralizer region where both are of equal intensity and velocity and directing the beam at a target to be destroyed. The region for merging the beams comprises a plurality of circular electrodes formed in a convex overlapping configuration with circular apertures for receiving ions from a ion source. A separate set of accelerator-decelerator electrodes is positioned to merge the electron beam into the ions in the beam merging region. After the beam leaves the beam merging region it enters an elongated axial magentic field which compresses the beam as it is directed to an object to be destroyed.This device may be housed in a satellite capable of being transported into space and moved within a kill radius of an object. The beam density is determined by the choice of ion species and by merging the beams in a low interaction energy environment.

Abstract: A color television display tube comprising three electron guns arranged in line and each comprising successively a triode part, a first lens electrode and a second lens electrode. The first lens electrode of each of the outermost guns is secured to insulating assembly rods by means of two suspension braces situated at an axial distance from each other in such manner that the brace situated nearer the triode part is secured to the outer surface of the first lens electrode remote from the central electron gun and the brace situated nearer the second lens electrode is secured to the outer surface of the first lens electrode facing the central electron gun. Such a construction results in a low thermal convergence drift.

Abstract: A gun for a linear-beam electron tube has a control grid for modulating the beam current which consists of an array of conductive web elements whose spacing from each other is much larger than their spacing from the concave emissive surface of the cathode. It was found that when this condition is met the grid can be operated at cathode potential while beam current is being drawn without distorting the electric accelerating field enough to ruin the focusing of the beam. Thus, when the grid is used to pulse the beam current on and off, it can have zero bias in the "on" condition, whereby the pulse modulator can be greatly simplified.
Abstract translation: 用于线性束电子管的枪具有用于调制束电流的控制栅格，该栅极电流由导电网状元件阵列组成，它们彼此的间隔比它们与阴极的凹形发射表面的间隔大得多。 已经发现，当满足这种条件时，栅极可以在阴极电位下操作，而束电流被拉伸而不使电加速场扭曲到足以破坏光束的聚焦。 因此，当栅格用于脉冲束电流通/断时，它可以在“导通”状态下具有零偏置，从而可以大大简化脉冲调制器。
