On some microwave physics research at Moscow State University and Russian Industries

Summary form only given. The further development of vacuum microwave electronics encounters fundamental limitations caused by the non-linear disgrouping effect of space charge fields in electron beams and needs extraordinary scientific and technical solutions. Only in Russia investigations in the new field of microwave electronics based on transverse grouping of homogeneous electron beam in circularly polarized electromagnetic fields of slow-wave structures and resonant cavities, were developed successfully. Experimental investigations were tightly combined with computer analysis using three-dimensional digital models. New types of microwave devices with unique sets of parameters have been designed, experimentally tested and manufactured. The development of these microwave devices has been made possible by the close collaboration of academic research at Moscow State University and industrial research and development at the Russian industrial firms ISTOK and TORIV. The report includes the discussion of some non-traditional devices.
