Abstract

An apparatus for attachment to a component of a microwave device, includes: a cage; a shield within the cage, wherein the shield is in a form of a container, at least a majority of the shield spaced away from an interior wall of the cage; and a connector at the cage, wherein the connector is configured to be connected to a cable connection, and wherein the connector is electrically connected to two terminals within the shield. An apparatus for coupling to an input connection of an electron gun, the input connection having a heater terminal and a cathode terminal, the apparatus comprising: a connector having a first end configured to be attached to a cable, and a second end configured to be connected to the input connection of the electron gun; and wherein the connector comprises an openingconfigured to receive the heater terminal of the input connection of the electron gun.

Description

technical field [0001] The field of the present application relates to accelerator systems, such as those used in medical systems, and more particularly, to systems and methods for electromagnetic interference suppression of accelerator systems. Background technique [0002] Radiation therapy involves the medical procedure of selectively delivering high-intensity radiation to certain parts of the body. A radiation device for delivering radiation therapy includes an electron source that supplies electrons and an accelerator that accelerates the electrons to form an electron beam. The electron beam is sent downstream where it strikes a target to produce radiation. The radiation is then collimated to provide a radiation beam with certain desired characteristics for therapeutic purposes. [0003] Radiation can also be used to provide imaging of the patient so that internal tissues can be visualized. [0004] A medical system that provides radiation for therapeutic or diagnost...
