Gyrotron Cavity with an Azimuthally Asymmetric, Mechanically Variable Cross Section

We propose an electromechanical method of continuous frequency tuning of the gyrotrons operating in the subterahertz frequency range. The method is based on the use of a quasisymmetric operating mode excited in a cavity with an azimuthally asymmetric cross section. Variations in the eigenfrequency o...

Beschreibung
Zusammenfassung:	We propose an electromechanical method of continuous frequency tuning of the gyrotrons operating in the subterahertz frequency range. The method is based on the use of a quasisymmetric operating mode excited in a cavity with an azimuthally asymmetric cross section. Variations in the eigenfrequency of the near-cutoff wave in such a cavity are ensured by changing its cross section mechanically.
