ABSTRACT

Results of experimental research related to focusing and transport of electron beam with small kinetic energy value via the Motz undulator are given in this paper. It is demonstrated that application of external driving magnetic field improves the conditions for beam insertion into the system and exerts influence on spontaneous radiation intensity. Resonance scattering of space charge waves on periodical heterogeneities of undulator magnetic field was obtained in a large current density mode. The issue of possible influence of the Cherenkov radiation mechanism upon undulator system resonance radiation was discussed.
