Abstract

The invention belongs to the field of high-power microwaves, and discloses a magnetic field structure of an integrated segmented internal and external saw-toothed special-shaped section solenoid. The magnetic field structure comprises an integrated segmented solenoid skeleton, wherein the integrated segmented solenoid skeleton includes a segmented front solenoid and a segmented rear solenoid, and an inserted waveguide slot is formed in the segmented part of the segmented front solenoid and the segmented rear solenoid; a coil package is wound on the surface of the integrated segmented solenoid skeleton, an insulated support gasket is arranged between the surface of the integrated segmented solenoid skeleton and the coil package, and the insulated support gasket is arranged in the coil package. According to the magnetic field structure disclosed by the invention, by adopting the internal and external saw-toothed solenoid winding area, high field strength can be provided, a high-uniformity magnetic field can also be provided at the segmented part, and meanwhile, the range of homogeneous areas can be enlarged; and by adopting the integrated mechanical design, the feeding waveguide can be inserted into the homogeneous area, and convenient assembly can be achieved.

Description

technical field [0001] The invention relates to the field of high-power microwaves, specifically, a guiding magnetic field shimming structure that satisfies the requirement of feeding a microwave seed source from a segmented part of a solenoid to cause a decrease in the uniformity of the magnetic field. Background technique [0002] In large and medium-sized devices such as front-end accelerators of high-power microwave sources, it is often necessary to provide a strong magnetic field environment to constrain the trajectory of electrons in order to achieve Transfer of high-current electron kinetic energy to microwave energy. Generally used microwave devices such as relativistic klystrons require stronger and stronger magnetic fields, higher and higher magnetic field uniformity, and larger and larger magnetic field uniform areas. However, the microwave seed source is fed from the microwave device, causing the solenoid to be segmented, and the uniformity of the segmented area...
