Cylindrical wiggler based on the solenoid loaded with different magnetic properties rings

摘要

The electrodynamics analysis of topography of constant magnetic fields originating in spatially periodic systemudis carried out. The system under investigation is the solenoid inside which rings from materials with different magnetic properties are periodically placed. The system of equations connecting amplitudes of spatial harmonics of audfield is obtained. This system is parsed numerically. Requirements are determined when in the spatial structure of audmagnetic field the dominating role is played by the main harmonic. The amplitudes of longitudinal and transverseudcomponents of the modulated magnetic field as a function of the ring sizes, magnetic and electric properties of ringudmaterials are investigated. The amplitudes of the fields obtained in the full consideration of electrodynamics areudcompared with the amplitudes of a periodic magnetic field, obtained in an impedance approximation is carried out.
