摘要：
Background The beam intensity of the High Intensity Heavy-ion Accelerator Facility (HIAF) is converted into current signals by beam intensity detectors and then processed by front-end electronics. The performance of the front-end electronics affects the measurement accuracy of the accelerator. Purpose To design front-end electronics to readout the current signals from a beam intensity detector. Methods A programmable transimpedance amplifier (TIA) converts current signals into voltage signals and amplify the signals. An analog-to-digital converter (ADC) converts analog signals into digital signals under the control of ZYNQ7015. Results and conclusion An integrated front-end electronics system was designed and verified. The electronics could collect and process current signals from 40 pA to 4 mA. The system had a higher dynamic range than traditional beam intensity measuring electronics.
