Abstract
Background: Currently, some modern spectroscopic applications require sub-terahertz
and terahertz continuous-wave electromagnetic radiation sources with power levels from 0.1 to 100
W. Gyrotron, a powerful high-frequency vacuum electronics device, is considered one of the promising
sources for these aims.
Methods: Modification of the gyrotron design promotes the widespread use of these devices for
DNP/NMR spectroscopy.
Results: Promising non-canonical concepts are presented, the features of which compare favorably
with the classical gyrotron scheme.
Conclusion: The gyrotron concepts we considered allow us to master the terahertz range and develop
a unique gyrotron installation for each scientific group, considering the specifics of their
scientific research.
