Mechanisms of an electron stream self-bunching in magnetron guns
Various processes of self-bunching of reentrant electron cloud nearby a distributed cylindrical cathode in crossed fields are investigated theoretically using particle-in-cell (PIC) simulation algorithms. As most probable mecha nisms of formation of an azimuthally heterogeneous electron beam, tang...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Various processes of self-bunching of reentrant electron cloud nearby a distributed cylindrical cathode in crossed
fields are investigated theoretically using particle-in-cell (PIC) simulation algorithms. As most probable mecha
nisms of formation of an azimuthally heterogeneous electron beam, tangential eigenmodes (i.e., natural tangential
oscillations) of the electron cloud, secondary-emission bunching of one and true solitons generation in the beam are
considered and compared. Illustrations of all just listed bunches as well as of some other turbulence phenomena at
the electron hub are given, and their possible influence on the magnetron guns performance is discussed. |
