Description
This paper presents a high-speed, high-precision sys-tem for measuring average beam current and lifetime, addressing the low data refresh rates of existing systems that fail to capture rapid beam dynamics. A comprehen-sive performance analysis identifies key error sources, including the beam probe, data acquisition card, elec-tromagnetic interference, and quantization noise. Exper-imental validation at the HLS shows that with a 0.5 μA resolution probe, the system achieves measurement ac-curacy better than 1 μA at a 1 Hz update rate and 2 μA at 100 Hz. This high-speed, high-precision current meas-urement enables rapid and accurate lifetime determina-tion. The system provides a critical tool for real-time monitoring of injection efficiency and beam stability, and offers essential data support for analyzing beam loss mechanisms and beam dynamics.
