Fast-rise high-field kicker magnet operating in saturation

Abstract

A new fast-rise and high-field kicker magnet system, based on the excitation over the saturation point of magnetic materials, is proposed. Several experiments have been carried out, and three times larger magnetic field density in a half rise time than a conventional kicker system has been achieved using a highly compact conventional magnet, with a low remanent field, less than 1 G. The new system is useful for particle ejection, especially in compact accelerators used in medical and industrial applications. The outline of this new system and experimental results are described here.
