Title:
HIGH-FREQUENCY INPUT COUPLER AND WAVEGUIDE
Document Type and Number:
WIPO Patent Application WO/2022/190405
Kind Code:
A1
Abstract:
The present invention is a high-frequency input coupler that is provided between a waveguide and an acceleration cavity and that inputs high-frequency waves from the waveguide to the acceleration cavity. The high-frequency input coupler is provided with: an inner conductor; an outer conductor provided on an outer circumference of the inner conductor; a high-frequency transmission window structure having a high-frequency transmission window; and a coaxial waveguide conversion part connected to the waveguide. The coaxial waveguide conversion part has: a high-frequency transmission window structure connection part for connecting the high-frequency transmission window structure; and an inner conductor connection part for connecting the inner conductor. The inner conductor has an inner conductor support body on the inner conductor connection part side. A space in which the inner conductor support body is disposed is formed in the inner conductor connection part. A buffer that can be electrically connected and that can be deformed is provided between the inner conductor support body and the inner conductor connection part.
