Abstract: A strongly magnetized plasma, e.g., the one encountered in a plasma filled backward wave oscillator (BWO), supports an obliquely propagating electromagnetic (EM) mode, k2, = (ki; - w2/c2)(w2/w2 - I), where w2p+C w2p W2 c w:2 w2p and k, are the pump wave frequency and pump wave vector, or, and wp are electron plasma and cyclotron frequencies. c is the speed of light in vacuum and e and I refer to the static magnetic field. As this mode acquires large amplitude it becomes susceptible to decay into a Trivelpiece-Gould (TGJ mode and a sideband electromagnetic mode. The growth rate of the instability scales as y =1/4u(k2,/X-k2)k(Wk/k2,C)v, where uosC is the electron oscillatory velocity, k and k, are the wave vectors of the low frequency electrostatic (ES) Trivelpiece-Gould mode and EM sideband wave. For typical BWO parameters the growth rate is of the order of the 10-s-1 range.
