Description

Linear rare earth permanent magnet (REPM) structures of split-pole type with harmonic distribution of magnetization for generators of synchrotron radiation are considered. The main attention is paid to issues of high order harmonic amplitude decrease at longitudinal Fourier-expansion of the field along the electron beam axis. It’s presented by a comparison that relative oberton amplitudes decrease down to 0.1% is possible at moderate discreteness of approximation rule of magnetization distribution in longitudinal direction instead of continuous one. Also, some considered systems incorporate unified permanent magnet pieces, in contrast, the well-known split-pole designs requiring a lot of types on magnetization.
