An Electron Beam Source for Novel Generators of Electromagnetic Radiation
Abstract
The microwave electron gun which is the focus of this project has been successfully operated, producing beam current of 0.5 A in a five microsecond pulse at pulse repetition rates up to 30 Hz. Studies of the performance characteristics of the gun are proceeding. Initially it has been determined that the new deflection magnet design produces a factor of two improvement over earlier designs. Coherent transition radiation produced when the electron bunches impact a metal screen has been observed in the microwave spectral region. Harmonics of the driving frequency have been detected to frequencies above 50 Ghz. Installation of more efficient interaction devices to extend both spectral range and power generated is in progress.
