Description

Non-destructive beam profile monitoring is a critical diagnostic capability for tuning modern heavy-ion accelerators. In this study, we present the design of a 16-channel wideband Beam Position Monitor (BPM) system for non-destructive transverse profile and temporal distribution measurements, specifically targeted for the ~10 MeV/u beamlines at the RAON heavy-ion accelerator facility. To facilitate accurate temporal distribution measurements, the BPM structure is optimized to achieve a broad frequency response with a bandwidth exceeding 8 GHz. High-frequency signal acquisition is performed utilizing a wideband sampling oscilloscope, capturing the transient beam signals directly in the time domain.
