Abstract
Hybrid focusing undulators were designed, manufactured and tested for some high power FEL and FEM projects. The magnetic fields of the undul ators themselves provide electron beam focusing in both transverse dir ections during e-beam transport through the interaction region. The ne w element of these devices is a side magnet array. The focusing transv erse magnetic field profile and enhancement of the magnetic field ampl itudes resulted from these side magnets. It is shown that wide range t unable focusing strengths can be ensured by a simple variation of the configuration of the side magnets. A flexible combination of quadrupol e focusing and sextupole periodic focusing is possible with using of t hese schemes.
