The traveling wave cyclotron (TWC) is defined in this paper as a cyclotron-type interaction of a nonrelativistic electron beam with traveling waves in an inductive periodic waveguide. Experimental results and a theoretical model of the TWC interaction are presented in this paper. The TWC experiment is conducted in the microwave regime (approximately 10 GHz) with low-energy (approximately 10 keV), low current (< 1 A) electron beam. Considerable RF amplification has been observed in the TWC experiment. A TWC theoretical model presented in the paper shows that the TWC amplification observed is the result of the inductive impedance of the periodic waveguide near cutoff.
