Description
The RFT-30 cyclotron at the Advanced Radiation Technology Institute (ARTI) of the Korea Atomic Energy Research Institute (KAERI) is a multipurpose proton cyclotron that delivers proton beams of up to 30 MeV for medical radioisotope production and the neutron applications. In the beam transport line, reliable information on the transverse beam position is essential for stable beam delivery and efficient beam tuning. A misaligned beam can collide with the beam pipe or nearby accelerator components, resulting in beam loss, unwanted activation, and potential hardware damage. Therefore, real-time beam-position diagnostics are required for the straight beamline section of the RFT-30 cyclotron.
This presentation introduces the design and optimization of a beam position monitor (BPM) specific to the beam conditions and beamline geometry of the RFT-30 cyclotron. The design process considered key parameters such as proton energy, beam current, beam pipe geometry, and bunch length. The electrode configuration and arrangement were investigated to enhance position sensitivity and signal response under the expected operating conditions. The proposed BPM is expected to provide real-time transverse beam-position information and contribute to stable beam tuning and operation of the RFT-30 cyclotron beamline.
