Abstract
A radiation source in which a beam of electrons is produced and directed along a path with dielectric material having a constant less than 4 in proximity to the path and an undulator providing oscillatory velocity modulation to the beam along the path for producing millimeter and sub-millimeter wavelength radiation.
Claims6
A radiation source comprising:
- electron means for producing a beam of electrons and directing said beam along a linear path;
- dielectric material having a dielectric constant less than 4 mounted in proximity to said path;
- means for providing Ubitron type of interaction oscillatory velocity modulation to said beam along said path for providing millimeter and sub-millimeter wavelength radiation.
