Abstract :
A novel means of producing coherent radiation by passing an electron through a dual-grating resonator is presented, The observed radiation is in accordance with the Smith-Purcell dispersion relation for a single grating. Feedback is provided by a second grating. Experiments carried out at beam energies from 30-55 keV produced radiation at wavelengths from 6 to 0.75 mm. Power measurement were used to clarify the grating beam interaction, Indications are that operation could be easily extended to shorter wavelengths to provide an inexpensive and compact radiation source in the far-infrared
