Vacuum Electron Sources of Terahertz Radiation

Abstract

Capabilities of vacuum devices in creation of compact and powerful terahertz sources will be discussed. Main attention will be focused on orotrons (or Generators of Diffraction Radiation) and on several varieties of gyrodevices (fundamental and second harmonic gyrotrons, high harmonic Large Orbit Gyrotrons, gyromultipliers). These generators can be available for many laboratories.
