LARGE-SIGNAL TRAVELING WAVE TUBE OPERATION: CONCEPTS AND ANALYSIS
Abstract
A large- ignal traveling-wave tube theory is derived, with special emphasis on physical concepts and on relating points of view from various analyses. The theory is one dimensionalAND INCLUDES EFFECTS OF SPACE CHARGE AND CIRCUIT LOSS. Special attention is paid to interpretation of terms in equations for power balance. A running comparison is made with work of Tien, Rowe, and others. The circuit equations of Pierce and Bernier are compared, and it is shown how both yield the sa e nsw rs if symbols for physical quantities are properly interpreted. Space-charg forces are calculated from a compressible-block model, an extension of Tien's disk model with continuous charge distribution between disks. A simplified theory is derived, neglecting the effects of any backward-wave component on the circuit; resulting computations compare well with those of other theories. All quantities are normalized to cold-circui voltage rather than beam voltage. Using calculated large-signal data, saturation power and maximum RF bunching of the beam are st died as f nctions of space charge, loss, RF drive, injection velocity, and gain parameter C. (Author)
