A unified terahertz radiation source based on a backward-wave tube

A unified terahertz radiation source based on backward-wave tubes is described. The device is intended for performing spectroscopic studies of condensed media, gases, and plasma in the frequency range 0.18–1.50 THz. The advantage of this design is the actual development of a terahertz radiation source with continuously tuned oscillation frequency in a wide range. No analogues of this instrument exist. Its schematic design is presented and individual functional units are described. The output radiation power is 0.5 mW–0.5 W, and the frequency range is 0.18–1.50 THz.
