The compact cold-cathode electron buncher (CCEB) is an electron source developed by Microwave Technologies that provides high-quality, high-current-density bunched electron beams for microwave tube applications and other electron-based devices used in research and industry. The CCEB is based on a miniature gated field-emitter-array cathode.  It offers a dramatic reduction in size and weight, reduced operating power requirements (no filament power required) and improved frequency response.  The CCEB provides super-fast turn-on high-current-density electron bunches for the next generation of microwave tubes and medical and industrial accelerators.
