Abstract
New hybrid permanent magnet undulator schemes were analysed with the g oal to find a magnet configuration providing electron beam focusing in both transverse directions. Numerical simulations with the 2D code PA NDIRA and the 3D code TOSCA were completed. It is demonstrated that us ing either side magnet arrays, satellite magnets or poles profiled by rectangular holes one could provide an effective focusing field profil e of the undulator. A complex magnet configuration appearing as 3D hyb rid undulator was also found which enables strong enhancement of the u ndulator field as well as transverse focusing.
