Problems solved by technology

A common problem associated with using an electron gun with a Linac is that some electrons can flow back towards the electron gun
As the impregnation material is deposited on the gate and its temperature increases due to the reflow of electrons, the gate may emit undesired electrons in an uncontrolled manner

Abstract

The present invention generally relates to systems and methods for generating controllable beam of electrons by using a hollow-cathode triode electron gun that substantially mitigate impact of back-streaming electrons.

Description

Background technique [0001] The present invention relates to systems and methods for generating a controllable electron beam using a hollow cathode triode electron gun that substantially mitigates the impact of electron backflow. [0002] Vacuum electron devices (VEDs), such as linear particle accelerators or klystrons, use an electron beam source, often called an electron gun. [0003] There are two types of conventional electron guns. The first type of electron gun is a diode electron gun with two electrodes, ie a cathode and an anode. The second type of electron gun is a triode electron gun with three electrodes (ie, cathode, anode and grid). [0004] Triode electron guns have operational advantages over diode electron guns. One advantage is that it allows rapid changes in the electron beam current produced by the electron gun. In the case of a diode electron gun, varying the electron beam current is accomplished by varying the high voltage difference between cathode an...
