どの間四、由を克服する必要がある。[Prior art and its problems] Traditionally, fiberscopes for cryogenic temperatures were not considered and were not used to monitor a wide area inside a cryostat, but recently the need for quenching of superconducting magnets has become less important. In order to create such a fiberscope for low-lighting, we needed to widely illuminate the λζ box and cover the area to be inspected as widely as possible. It is necessary to overcome the reasons.
