Hybrid Magnet Wiggler for SR Research Program at VEPP-4M

A compact hybrid magnet wiggler is under development for the VEPP-4 SR research program. The wiggler allows increasing the photon flux two orders of magnitude at a beam energy of 4.5 GeV in the spectrum range of 60-100 keV. The magnet consists of conventional coils, which generate a magnetic field, and permanent magnet insertions, which concentrate the flux. This solution increases the field in the beam orbit up to 2.05 T. Here we present the design, magnetic calculations and analysis of the beam dynamics under the hybrid wiggler influence.
