GENERATION OF SUB-MILLIMETER RADIATION BY A BUNCHED BEAM OF RELATIVISTIC ELECTRONS.
Abstract
The interaction of a bunched beam of relativistic electrons with several different microwave circuits was analyzed, with a view toward the generation of electromagnetic radiation in the submillimeter wavelength region. Because of relativistic effects, it was possible to use structures which had dimensions large compared to the desired wavelength. A relativistic electron beam was obtained from a traveling-wave linear accelerator which operated at a frequency of 9288 Mc/sec. The interaction properties predicted by theory were compared with the experimental results obtained from resonant cavities, from a dielectric-loaded slow-wave structure, and from two other special structures: a magnetic undulator and a sinuous waveguide. In the case of the magnetic undulator, approximately 150 milliwatts were generated at 5.4 millimeters, and 35 milliwatts at one millimeter. The shortest wavelength observed was 0.4 millimeter at a power level of 40 microwatts. (Author)
