Currently, researches on nuclear synthesis and ion acceleration are being actively conducted in advanced countries such as ITER and CERN. Since the succesful operation of KSTAR in Korea, it has been progressed to development and research on accelerators, and RAON, a Korean heavy ion acceleraor, has been under construction since 2011. Based on our experience in manufacturing a number of superconducting and cryogenic facilities, we have been directly or indirectly participated in the construction of RAON project from the equipment required for cooling systems or facilities heavy ion accelerator.
