Abstract The gyro-peniotron shows great promise as a source of microwave radiation. In this paper we investigate the stability and the non-linear saturated efficiency of a gyropeniotron oscillatro with an axis encircling beam operating at the TE211 and the TE311 cylindrical cavity modes. Beam and cavity parameters for stable high efficiency operation are presented from a linear theory analysis of the start-oscillation condition. Using design parameters taken from the linear analysis, the strong field non-linear emission efficiencies are studied numerically. The sensitivity of the saturated efficiency to beam axial velocity and guiding center spread is also considered. The results of our modeling indicate that high efficiency (70–90%) operation of the gyro-peniotron oscillator is possible, even with large guiding center $$(\delta r_{gc_ \circ } \mathop〈 \limits_ \sim 0.2 - 0.4r_{L_ \circ } )$$ and large axial velocity $$(\delta \beta _{||} \mathop〈 \limits_ \sim 0.3\beta _{||_ \circ } )$$ spread.
