摘要

Korea-4GSR has been under construction since 2021 to accelerate and store a 4 GeV electron beam. One of the key features of Korea-4GSR is its 2 T normal conducting bending magnet, which is positioned at the center of each cell within the storage ring. This central bending magnet allows for the extraction of photon beams for beamline experiments. Recently, research has focused on high-temperature superconducting magnets to achieve higher magnetic fields in Korea. In this context, we have conducted beam optics studies using a high-temperature superconducting bending magnet (referred to as “superbend”) in place of the normal conducting bending magnet at Korea-4GSR. This paper presents our simulation results regarding beam optics with the superbend in the Korea-4GSR storage ring and discusses the resulting characteristics of the photon beams produced.
