Dr. ADACHI Kyosuke of Accelerator Section II Receives the Beam Physics Young Presentation Award 2025
Dr. ADACHI Kyosuke, a postdoctoral researcher of Accelerator Section II, received the Young Presentation Award 2025 at the 2025 Beam Physics Workshop and Young Researchers' Meeting for his presentation entitled "Optimization study of bunch lengthening with second harmonic RF voltage in J-PARC RCS." This award is presented to outstanding young researchers and students in the field of beam physics in order to encourage their research activities and support their independence and development as researchers and professionals.
Dr. ADACHI investigated a method for flattening the beam bunch shape by applying a radio-frequency voltage with twice the fundamental frequency during the final stage of acceleration in the accelerator. This approach successfully reduced beam loss and is expected to contribute significantly to realizing even higher-intensity beams at J-PARC.
