The 2nd cyclotron harmonic peniotron oscillator with a magnetron type waveguide cavity has been studied experimentally. The highest electronic efficiency of 43-8% was obtained at the TE311 resonant-like mode (explained later) in the cavity at 10-5 GHz and oscillations due to the backward wave interaction were also observed at several longitudinal modes in the approximate frequency range 11 GHz-13 GHz. This paper describes the design procedure of our test tube and shows its operational characteristics.
