Description

The high-frequency cavity system of the Wuhan Advanced Light Source (WALS) utilizes a normal temperature single-cell cavity with heavily damped higher-order modes. The operating frequency of this cavity is 499.654 MHz. Power from a solid-state power source module passes through a circulator and then is fed into the main cavity via a waveguide. The coupler is designed to be compatible with both circular waveguides and coaxial waveguides, and the coupling coefficient can be continuously adjusted within the range of 1 to 3. This paper reports that in November 2024, the 500 MHz normal temperature high-frequency cavity of WALS has successfully completed a 50 kW high-power test, effectively validating the performance of the high-frequency cavity and the stability of the high-frequency system.
