The experimental demonstration of a gyrotron backward wave oscillator (gyro-BWO) using a cusp electron gun and helically corrugated waveguide will be presented. Operating in the W-band frequency range the gyro-BWO is predicted to output ~10 kW with a frequency tuning range of 85-104 GHz at 18% electronic efficiency before the energy recovery. The annular axis-encircling electron beam has been experimentally...
The gyrotron-backward wave oscillator (Gyro-BWO) is an efficient source of coherent, high-power microwaves over the centimeter to millimeter wavelength range. At the University of Strathclyde a project has been undertaken to create a Gyro-BWO in the W-band frequency band (75 -110GHz) outputting in continuous wave (CW) operation. The dispersion for the waveguide was found numerically, analytically...
Presented is the design of a cusp electron gun that is be used in a Gyrotron-Backward Wave Oscillator which is operating in the W-Band (75 - 110 GHz) frequency range. A cusp gun uses a non-adiabatic magnetic field reversal to impart azimuthal motion on an electron beam forming an axis-encircling beam. The cusp gun was designed to generate a beam of 2 A at 40 kV with a pitch factor of 1.65, in order...
