Description
This paper presents the design of low-level radio frequency (LLRF) systems based on the MicroTCA.4 standard for particle accelerators. LLRF systems regulate cavity field amplitude, phase, and resonance to ensure stable beam acceleration, while supporting high-speed data acquisition, diagnostics, and automated control. MicroTCA.4 offers high performance and modularity through AMC, RTM, and MCH modules, providing standardized distribution of clocks and triggers, redundancy, and intelligent management. Hardware implementations employ direct sampling and down-conversion schemes, with FPGA frameworks integrating PCIe, DMA, and DDR subsystems for real-time control and data acquisition. The use of Xilinx IP cores and open-source drivers enables efficient high-bandwidth data transfer, while EPICS integration facilitates system monitoring and operation. Results demonstrate that MicroTCA.4 delivers a standardized, cost-effective, and reliable platform, simplifying development and accelerating deployment of modern LLRF systems.
