Description

The beam current monitor for the Hefei Advanced Light Facility (HALF) can acquire the slow, high-precision DC signal from the DCCT and the high-repetition-rate (500 MHz), broadband narrow pulses from a stripline beam position monitor (SBPM) simultaneously. The SBPM was specifically designed for HALF and we deal with the special signals in the time domain. Conventionally, commissioning such processors used up the costly accelerator beam time. To overcome this limitation, we have constructed a laboratory closed-loop test system that replicates realistic beam signals. A programmable current source emulates the DCCT signal, while a custom beam signal simulator built on an RF system-on-chip (RFSoC) platform generates the SBPM-like wideband pulses with ultra-high sampling rate and high time-domain fidelity. The simulator output closely approximates true beam waveforms, providing a realistic test environment. This work eliminates the reliance on physical beam for the development and validation of beam instrumentation electronics and offers an efficient, repeatable test solution that can significantly reduce machine time occupation.
