INVESTIGATION OF SYNCHRONOUS-WAVE R-F TO D-C CONVERSION.
Abstract
A device for converting microwave power into electrical power in either d-c or low frequency a-c form is investigated both theoretically and experimentally. An electron beam passes through a Cuccia coupler where it receives microwave power in the form of cyclotron rotation, then enters a region of decreasing magnetic field which accelerates the beam along the axis of rotation. The increased longitudinal kinetic energy is recovered as electric energy by a depressed collector. A simple kinematic analysis demonstrates that the Cuccia coupler can convert large amounts of microwave power into electron beam rotation. Although the inertial mass increase introduces some difficulties in Cuccia coupler operation, these difficulties are surmountable, and satisfactory coupler operation can be achieved for a relatively wide range of operating conditions. In most cases, relativistic operation is superior to that predicted classically. Four tubes and a gun-collector tester prototype were tested experimentally. The gun-collector tester prototype gave efficiencies from 36 percent to 75 percent. A fourth tube yielded measured efficiencies up to 34 percent, or when corrected to disregard cavity losses, up to 59 percent. (Author)
