Abstract

The linear growth rate of the electromagnetic and electrostatic instability in a plasma filled backward wave oscillator without a guiding axial magnetic field, are analyzed. It is shown that the absence of the external magnetic field has a small influence on the electromagnetic instability but profound effects on the electrostatic instability. The operation of a backward wave oscillator is found to be obtained when the space charge of the electron beam is neutralized by the plasma.
