Abstract: | |||||||
The effect of the strong external magnetic field is studied on the
dielectric Cherenkov maser, which is included with an axial thin
annular relativistic electron beam and a plasma column in a
dielectric lined slow-wave waveguide. The dispersion equations of
the beam-wave interaction are derived. The growth rates of the
wave are obtained, and the effects of the accelerating voltage,
beam current and the background plasma density on the growth rate
of the wave are numerically calculated, discussed, and compared in
the presence and absence of external magnetic field.
