Terahertz Gyrotrons with Unique Parameters

Development of high power THz sources play important role for development advance technologies in physics, chemistry, biology, medicine. The main goal of this report is present together data about gyrotron development and the most striking examples of modern applications. The paper describes some features of THz tubes. The key information about pulsed and CW tubes is given. The described gyrotrons demonstrate (in some specific combinations) extremely low voltage and beam current, narrow frequency spectrum, wide range frequency tuning. Novel schemes of high frequency gyrotrons are analyzed. Examples of gyrotron based experiments for spectroscopy, data transmission and localized gas discharge are presented.
