Abstract : The patent describes an apparatus for generating a relativistic annular electron beam with a power in the 10 to the 10th power watt range using a solid conical cathode of blunted shape and a surrounding truncated anode. A high intensity, pulsed magnetic field guides and focuses the electrons emitted from roughened areas of the cathode by a cold field emission process to form the annular beam.
