In this study, behavior of
TWT propagation constants obtained from interaction of electron beam and
electromagnetic wave in a typical traveling wave tube amplifiers is analyzed.
First of all, dispersion equation is derived from TWT beam- wave interaction.
Acquired equation is simplified by using Pierce normalization parameters.
Behaviors of all wave-type solutions related to TWT are determined for
different Pierce normalization parameter sets by looking incremental
propagation constants of TWT. In this context, three main cases are considered.
In each of three main cases, only synchronization, space charge and circuit
loss parameters are swept in a certain value range and other related
normalization parameters are taken constant, respectively. Hence, root-locus
curves of incremental propagation constants of wave type solutions in TWT are
deeply analyzed.

Bu çalışmada tipik bir yürüyen
dalgalı tüp kuvvetlendiricisindeki (TWT) elektron demeti ile elektromanyetik
dalganın etkileşimi sonucu elde edilen TWT iletim sabitlerinin davranışı incelenmiştir.
Öncelikle, TWT demet dalga etkileşiminden dispersiyon denklemi çıkarılmıştır.
Elde edilen denklem, Pierce normalizasyon parametreleri kullanılarak
basitleştirilmiştir. Farklı Pierce normalizasyon parametre takımları için TWT
ye ait tüm dalga tipi çözümlerin davranışları TWTnin artırılmış iletim sabitlerine
bakılarak tespit edilmiştir. Bu bağlamda üç ana durum ele alınmıştır. Bu üç ana
durumun her birinde sırasıyla sadece senkronizasyon, uzay yükü ve devre kaybı
parametreleri belirli bir değer aralıklarında süpürülmüştür ve ilgili diğer
normalizasyon parametreleri sabit alınmıştır. Böylece TWTdeki dalga tipi çözümlerin artırılmış iletim sabitlerinin kök-yer
eğrileri derinlemesine incelenmiştir.
