국내 대형 가속기 소개 동영상:
본 연구그룹은 고도화된 빔 물리 모형 및 수치해석 코드, 첨단 빔 진단 및 제어 장치를 활용하여, 국내외에 건설 또는 운영 중인 대형 가속기의 설계 및 구축, 최적화 및 성능향상에 기여하고, 나아가 지금보다 가속 효율이 10~100 배 높은 첨단 고강도 가속기 개발에 필요한 물리적-기술적 난제에 도전한다. 이러한 첨단 가속기는 핵융합 재료 연구, 원자력 폐기물 처리, 암 치료, 신소재/신약 개발, 우주의 신비 탐구 등 인류가 당면한 여러 문제를 해결하는 데 필수적인 첨단기술이다.
Several large-scale accelerator facilities are operational or under construction in Korea, such as the 3rd Generation Synchrotron Light Source (PLS-II) and the X-ray Free Electron Laser (PAL-XFEL) in Pohang, the Korea Multi-purpose Accelerator Complex (KOMAC) in Gyeongju, the Rare Isotope Accelerator complex for ON-line experiments (RAON) in Daejeon, and the SNUH Gijang Cancer Center of Heavy Ion Therapy and Study (SGCC-HITS). Plus, a new 4th Generation Storage Ring (4GSR) is being constructed in Cheongju. By using advanced beam physics models and simulation tools, cutting-edge beam diagnostics, and sophisticated beam manipulation/acceleration techniques, our research group contributes to the design, development, optimization, and improvement of those modern accelerators. Furthermore, we investigate transformational technologies for the next-generation high-intensity accelerators such as the Fusion Materials Irradiation Facility (FMIF), Accelerator Driven System (ADS), and Heavy Ion Fusion (HIF). Applications of the accelerators to cancer therapy (FLASH), new materials research/drug discovery, and laboratory astrophysics will also be actively pursued.
