MILLIMETER WAVE GENERATOR FAST WAVE UNDULATION PRINCIPLE.
Abstract
This report describes the results of a program designed to demonstrate the capabilities of the Ubitron amplifier as a generator of extremely high pulse and average power at millimeter wavelengths. A variety of circuits was tested at V-band including a loaded waveguide circuit, an extended interaction circuit, and a cascade backward-wave amplifier circuit. Investigation was made of the limitations placed upon the design parameters by such items as voltage breakdown within the gun, pulse and average heating on the circuit and in the collector, and collector and window design. A tube was designed and fabricated with output in the TE01 circular mode and input in standard rectangular waveguide. The circuit is a fast-wave circuit (unloaded TE01 circular waveguide mode) and is fabricated from alternating steel and copper rings which are placed in the field of the solenoid to form the periodic magnetic field. A hollow electron beam is used to interact with the circuit, and this beam is produced from a magnetron injection gun. The beam is collected directly on the wall of the output waveguide directly before a circular waveguide window. (Author)
