Abstract : The patent describes a method of preventing deleterious backward wave oscillations in a high powered traveling wave tube. A loss, introduced at selected frequencies, effects the backward oscillation prevention. This method inherently provides a high heat transfer capability since the loss may be introduced by the moving fluid that dissipates the heat generated in the fluid. The selection of a particular fluid and the dimensions of the hollow support ceramic fluid flow tubes result in selective loss in the range of 6-8 GHz in a TWT designed for operation between 2 and 4 GHz.
