High-power microwave radiation at 8 GHz from a gas-fined backward wave oscillator driven
by an intense relativistic electron beam has been measured. It has been observed that an order
of magnitude resonant increase in microwave output power occurs at a particular pressure of
the background gas. This resonance has also been observed to be strongly dependent on the
value of applied axial magnetic field. Possible explanations for the observed results are
discussed.
