Improvement of large signal interaction model for TWT
Abstract
Because of the nonconservation of energy in Rowe's model for large signal interaction in traveling wave tubes (TWT), Rowe's model produces considerable error in TWT design, especially for a velocitytapered one. A modified model which is based on energy conservation is suggested to improve the accuracy of the design of TWT. By the new model, when the loss and space charge in TWT are neglected, the energy received by the circuit is exactly equal to that given by the electron beam. All the results obtained with the new model are in better agreement with the actual cases than those obtained with Rowe's model.
