Description
Magnetrons offer high energy efficiency, making them attractive power sources; however, their RF output lacks the phase and amplitude stability required for high-precision applications like particle accelerators. While techniques like RF signal injection have been explored to stabilize magnetron outputs, this research introduces a Low-Level RF (LLRF) control framework designed to enhance signal quality further. This is achieved by combining injection locking with parallel control mechanisms, such as DC power supply modulation. To ensure efficient implementation, the proposed architecture leverages optimized digital processing, specifically utilizing 4-IQ sampling techniques on novel hardware architectures. Additionally, mathematical models are developed to enable controller synthesis following a Model-Based Design (MBD) methodology. By integrating injection locking, multi-variable parallel control, efficient digital processing, and model-driven design, this work seeds a robust and stable RF power source tailored to particle accelerators.
