TI - RF Developments for HEPS J2 - Proc. of eeFACT2022, Frascati, Italy, 12-16 September 2022 CY - Frascati, Italy T2 - ICFA Advanced Beam Dynamics Workshop on High Luminosity Circular e+e- Colliders T3 - 65 LA - english AB - High Energy Photon Source (HEPS), a 6 GeV diffraction-limited synchrotron light source, is currently under construction. The double-frequency RF system is being developed to deliver 5.4 MV of RF voltage and 900 kW of beam power with an active third harmonic system. The prototypes of the higher-order-mode-damped 166.6 MHz quarter-wave superconducting cavities, as well as the first 499.8 MHz harmonic superconducting cavity, have been fabricated and vertical tested, while the cryomodules for these cavities are being developed. Following the success of the prototype 166.6 MHz 260 kW and 499.8 MHz 150 kW solid-state power amplifiers, the series production has been launched. The new low-level RF control system based on Xilinx FPGA is in the prototyping phase and the first lab test results fulfill the HEPS requirements. The installation of the booster RF system will be launched in Fall 2022. This paper presents the status and progress of the RF system for HEPS. PB - JACoW Publishing CP - Geneva, Switzerland ER -
