Design of A Permanent Quadrupole Magnet with Adjustable Magnetic Field Gradient

Journal of Physics: Conference Series
Abstract As compared to traditional magnets, permanent magnets can effectively reduce energy consumption and eliminate the impact of current ripple and the water cooling system on beam current. The use of permanent magnets in accelerators has become a new trend as permanent magnet technology has advanced.
