Effect of structure length on relativistic backward-wave oscillator properties

Data show that a high-power backward-wave oscillator’s (BWO) nonlinear saturation properties are dependent on slow-wave structure length. Results from an experimental investigation comparing the individual output from two high-power (60 MW), X-band BWOs operating in the Raman regime at saturation am...

Description
Summary:Data show that a high-power backward-wave oscillator’s (BWO) nonlinear saturation properties are dependent on slow-wave structure length. Results from an experimental investigation comparing the individual output from two high-power (60 MW), X-band BWOs operating in the Raman regime at saturation amplitudes are presented. The two BWO slow-wave structures are identical in all respect except length. Comparisons are made of the BWOs’ microwave frequency, peak power, and pulsewidth output which are, in turn, parameterized with respect to the electron beam energy.
