ABSTRACT:
The noise in a crossed field amplifier output is reduced by providing a non-uniform magnetic field across the surface of the cathode. This may be achieved by providing a curved magnetic field across the cathode or by providing a concave shaped cathode. Additionally the cathode may be tilted with respect to the cross magnetic field.
