Description

The Advanced Radiation Technology Institute (ARTI) of the Korea Atomic Energy Research Institute (KAERI) operates the RFT-30 cyclotron, which extracts proton beams up to 30 MeV for medical radioisotope production and neutron experiments. For stable beam operation, real-time monitoring of the beam position after acceleration is essential. Beam loss caused by collision with the beam pipe or accelerator components can lead to unwanted activation and hardware damage. Therefore, a beam position monitor (BPM) is required for the straight beamline section of the RFT-30 cyclotron.
In this study, a BPM suitable for the beam conditions of the RFT-30 cyclotron was designed and optimized. The design considered major parameters, including proton energy, beam current, beam pipe geometry, and bunch length. The electrode structure and arrangement were investigated to improve position sensitivity and signal response. This presentation introduces the BPM design procedure, key design parameters, and optimization results. The proposed BPM is expected to support stable beam operation and real-time beam diagnostics for the RFT-30 cyclotron beamline.
