摘要：

A bunch-by-bunch beam position measurement (BPM) electronics for High Energy Photon Source (HEPS) storage ring was designed. The hardware of electronics consists of analog signal acquisition board and digital signal processing board. The software consists of underlying firmware and application software. The sampling frequency is 500 MHz, and the bandwidth is 1 GHz. The electronics digitizes four analog signals from BPM probe of storage ring, and obtains the amplitude of beam signal. ZYNQ chip was used to process the beam data and calculate the position of each bunch. Electronics test results in the laboratory is that the nonlinearity of ADC channels is less than 1% when the peak-to-peak value of input signal is less than 1.8 V, and spurious-free dynamic range is about 60 dB. When the sensitivity coefficient is 8.26 mm, the beam position resolution is less than 10 μm. The test results meet the needs of HEPS. © 2020, Editorial Board of Atomic Energy Science and Technology.
