Abstract :
An analysis of the propagation characteristics of coupled-cavity (CC) delay lines in traveling-wave tubes (TWTs) under hot conditions is proposed. Using this approach a necessary impedance level at the end of the periodic line is derived that leads to minimum input reflections during operation. From this matching condition a required cold input reflection can be predicted which is in general different from the one commonly used.
