This paper discusses the development of replacing klystron magnets used in the Compact Linear Collider （CLIC） project at CERN with MgB₂ superconducting magnets. The study confirms that this replacement can reduce power consumption to less than one-seventh of that of the current normal conducting magnets, and to one-thirteenth when two units are connected in parallel as a pair klystron system. Additionally, the paper presents the results of combination tests with klystron at CERN. It also covers the development status of high-strain-resistant MgB₂ wires and recent advancements in MgB₂ magnet technology.
