Single-cavity gyromultipliers

Several new configurations of self-exciting gyro-multipliers are proposed. These schemes allow concurrent excitation of radiation at fundamental and harmonic frequencies in a single resonator. It is shown that such an approach simplifies the experimental setup and promises high device efficiency. Experimental proposals based on some of the schemes are presented

Prospective THz Gyrotrons for High-Field Magneto-Resonance Spectroscopy

A high-harmonic Large Orbit Gyrotron and a low-voltage gyrotrino placed inside a spectrometer cryomagnet enable greatly simplify terahertz systems for magneto-resonance spectrometers. Large Orbit Gyrotrons provide a powerful third-harmonic generation at frequencies of 1 THz and 0.394 THz in pulsed and CW regimes, respectively, at significantly lower magnetic fields than conventional gyrotrons. According to simulations the gyrotrino with the voltage of 1.5 kV and frequency of 0.264 THz can generate a power of tens of watts; a possibility to operate at such a low voltage is demonstrated in the existing gyrotron with three-electrode magnetron-injection gun
