Summary:Experimental and theoretical investigation of some instabilities developing in the relativistic electron beam in the periodical magnetostatic pump is presented. It is shown, in particular, that under cyclotron resonance condition the generation of the electromagnetic waves is possible in a broadband regime. This broadband regime is due to development of cyclotron mode broadband instability not investigated earlier.
