ABSTRACT:
An undulator providing an increased variable wavelength range of an radiation light. An electron beam, interacting with a microwave as a traveling wave, propagates in a sinuous curve in a waveguide. In the course of propagation, a radiation light is emitted in the direction of propagation of the electron beam. The wavelength .lambda. of the radiation light emitted may be changed greatly by varying the frequency of the microwave.
