Дата публикации: 03-05-2018.A system for injecting radio frequency (RF) pulses into an RF linear accelerator (RF LINAC) cavity is described. In accordance with the description an RF power amplifying element, typically a compact planar triode (CPT), is directly mounted to an outside of a hermetically sealed RF cavity. The direct mounting of the RF power amplifying element places the antenna—responsible for coupling power into the RF cavity—physically on the RF cavity side of a hermetic high-voltage (HV) break. The RF input, RF circuitry, biasing circuitry, and RF power amplifier are all outside of the vacuum cavity region. The direct mounting arrangement facilitates easy inspection and replacement of the RF power amplifier, the RF input and biasing circuitry. The direct mounting arrangement also mitigates the deleterious effects of multipactoring associated with placing the RF power amplifier and associated RF circuitry in the vacuum environment of the RF LINAC cavity. 1. A system for injecting radio frequency energy into an accelerator , the system comprising:a vacuum chamber containing a cavity structure; an RF power amplifier located, in operation, external and adjacent to the vacuum chamber,', 'a socket interface that complementarily accepts the RF power amplifier,', 'an electrically insulating break between the socket interface and the cavity structure, and', 'an antenna located within the cavity structure, wherein the antenna is connected to the socket interface and electromagnetically coupled to the cavity structure; and, 'a power amplifier assembly directly coupled to the cavity structure, wherein the power amplifier assembly comprises a biasing element to bias the power amplifier assembly, and', 'an RF power source supplying a radio frequency energy to the power amplifier assembly for amplifying by the RF power amplifier and transmitting a resulting amplified RF power into the cavity structure., 'a power supply interface including2.
