Development of a 540° Magnetic Buncher Based on Permanent Magnets

bstract —To obtain short electron bunches with a large charge, special magnetic systems with a strong dependence of the time of flight on the particle energy, so-called magnetic bunchers, are used. This paper considers one of the variants of such a system and describes its main elements: magnetic mirrors. Permanent magnets are used to simplify the design and increase the stability of the magnetic field.
