Abstract :
The letter describes a method of reducing the broadband noise of a high-power injected-beam crossed-field amplifier by means of a nonuniform magnetic field in the electron-gun region. The noise reduction achieved is some tens of decibels, and also results in improvements in other characteristics of the tube.
