Theoretical analysis of self-oscillations
excitation mechanisms in magnetrons with cold secondary-emission cathode without
the use of an auxiliary thermocathode was carried out. Processes of
self-oscillations excitation using modulated pulse of anode voltage were
studied. Conditions , when this type of self-oscillations excitation mechanism
is possible to be realized, are defined.
Keywords: magnetron, cold startup.
