“…For obtaining proper transverse beam focusing, a useful combined function RTM magnet design was first introduced by Froelich et al [3] . The bending magnets were not homogeneous but consisted of three distinct triangular field regions, still yielding a 180°b end for all energies, but also creating two quadrupoles, one at each boundary between adjacent field regions (edge focusing).…”

Progress is reported on a 25 MeV injector racetrack microtron for a 10 wm radiation free electron laser (TEUFEL project). The accelerator exhibits transverse focusing in 180°inhomogeneous two-sector dipole magnets which are slightly rotated with respect to each other in the bending plane. This provides closed orbits, isochronism and a large transverse acceptance. Details on this unconventional microtron focusing system will be given. An analytical treatment, based on conformal mapping, of the field near pole boundaries and at the hill-valley boundaries in the microtron dipole is compared with Poisson calculated results and with field measurements . The design of a model accelerating cavity is presented together with field measurements based on the perturbation ball method.
