PULSED MILLIMETER AND SUBMILLIMETER WAVE GENERATION

Publisher:Ohio State University
Prebunched electrons from 1 MeV and 40 MeV electron gun systems have been used to produce short pulses of spectrally pure millimeter and submillimeter waves. Several microwave couplers, including waveguide and Orotron geometries, were used to demodulate the picosecond structure of the electron beam. The spectral extent and purity of the signal generated were measured by use of a Fourier transform spectrometer and spectrum analyzer, respectively. The design and test of the Orotron cavity and its periodic structure will be presented.
