|Issue Date:||9-Feb-2018||Source:||IVEC 2017 - 18th International Vacuum Electronics Conference (2018-January): 1-2 (2018-02-09)||Journal or Series Name:||IVEC 2017 - 18th International Vacuum Electronics Conference||Abstract (english):||Two techniques for suppressing backward-wave oscillations in homogeneous helix sections of traveling-wave tubes are presented. For this purpose, the focusing magnetic field is modified. The first technique aims at compressing the electron beam in order to reduce beam-wave coupling. The second one changes the beam rotation to affect the backward-wave interaction. Both techniques increase the margin against backward-wave oscillations significantly. Theory and simulation results are presented and compared.||URI:||http://hdl.handle.net/11420/2457||ISBN:||978-150905915-7||Institute:||Hochfrequenztechnik E-3||Type:||InProceedings (Aufsatz / Paper einer Konferenz etc.)|
