System for processing beam position monitor signal

Abstract

Disclosed are a system and method for processing a beam position monitor signal. The system includes an analog-to-digital converter (ADC) sampler configured to measure signal intensity through the optimization of an ADC sampling rate and bits using a radio frequency (RF) switch and a low noise amplifier (LNA) and to convert an analog signal into a digital signal and an FPGA configured to perform digital signal processing. The FPGA is further configured to include a digital signal synthesizer configured to extract only an optimized harmonic signal of multiple harmonic signals of the digital signal converted by the ADC sampler through a digital band pass filter so that the multiple harmonic signals are separated and signal processing is performed for each harmonics, and an IQ calculator configured to perform beam position measurement, beam position measurement and relative beam current measurement on the extracted digital signal through a digital circuit.
