Aiming at the requirement of beam position measurement accuracy for heavy ion accelerator, the automatic gain calibration method of beam position detector channel is studied, and the design of automatic gain calibration of simulated BPM signal, laboratory calibrated BPM signal, and online beam BPM signal is realized. Firstly, the overall design of the ADC automatic gain system is introduced. Secondly, each sub-function module of the ADC automatic gain system is designed and implemented on Matlab software, and the correction processing with noise and without noise is compared. Finally, the consistency of simulated beam data, laboratory calibration data, and online beam data is tested respectively. The experimental results show that the method makes the four noisy analog signals basically the same in amplitude, and effectively reduces the error caused by the inconsistent gain of each signal channel of the ADC.
