Loading and frequency conversion tuning cavity of large power ferrite

Abstract

The invention mainly relates to a loading and frequency conversion tuning cavity of a large power ferrite. The tuning cavity comprises a left resonant cavity (1) and a right resonant cavity (2) which are coaxially and oppositely arranged; a plurality of cavity loaded ferrite magnetic rings (6) are filled between an inner conductor (15) and an outer conductor (16) of the right resonant cavity (2); an insulating tetrafluoride medium (8) is filled between the inner diameters of the ferrite magnetic rings (6) and the inner conductor (15); a first field bias coil conductor (9) is arranged in the insulating tetrafluoride medium (8); a second field bias coil conductor (10) is installed at the outer part of the ferrite magnetic ring (6); a vacuum chamber (3) is arranged in the center of the inner conductor (15) of the right resonant cavity (2); a corrosion resistant casing (23) is installed at the outer part of the right resonant cavity (2); and a supporting corrosion resistant plate (17) is arranged on the side of the right resonant cavity (2). The tuning cavity can not only be operated in frequency sweep impulse modulation mode, but also be operated in radio frequency continuous wave mode within the frequency range of 0.5 MHz to 2 MHz, and meets the requirement of double mode operation of a CSR experimental ring high frequency system.

Description

Technical field: [0001] The present invention mainly relates to the technical field of ferrite-loaded broadband high-frequency high-voltage synchrotron device that forms a high-frequency high-voltage electric field in a vacuum and captures, accelerates or decelerates heavy particle beams in the direction of beam movement, and particularly relates to a A high-power ferrite loaded frequency conversion tuning cavity. Background technique: [0002] Before that, there was only one synchrotron coaxial resonator loaded with ferrite loaded with frequency conversion tuning by the Institute of Modern Physics of the Chinese Academy of Sciences and Russia, which was jointly designed and manufactured in China, and was used for the main ring of the cooling storage ring (CSR) of the Lanzhou Heavy Particle Accelerator. The beam is captured and accelerated. Due to its simple structure, the highest average high-frequency power it can withstand is no more than 2kW, and it can only work in the...

Problems solved by technology

When the duty ratio is large, the cavity voltage is high, or in the case of continuous wave operation, the temperature of the ferrite will be too high, the insulating medium will heat up, and the tuning capacitor will burn out
