PROJECT TITLE :
Simulation of Drive-Induced Oscillation in Coupled-Cavity TWTs
Drive-induced oscillation (DIO) is an instability that limits the achievable output power in wideband coupled-cavity traveling wave tubes (CC-TWTs). It happens beneath massive-signal conditions, when the electron beam is slowed as a results of its interaction with the circuit at the drive frequency. DIO happens at a frequency terribly close to the point (band edge) of the lower branch of the cold circuit dispersion diagram. It's commonly in the midst of a boost in the body current and a flattening of the power transfer curve at the drive frequency. The correct prediction of the conditions for onset of DIO would be helpful to the designers of CC-TWTs. During this paper, we have a tendency to present an approach to the prediction of DIO thresholds using the multifrequency large-signal simulation code TESLA-CC.
