螺旋線行波管大信號(hào)相互作用模型的改進(jìn)
IMPROVEMENT ON THE LARGE SIGNAL INTERACTION MODEL FOR TWT
-
摘要: 由于Rowe模型的能量不守恒性,使它用于實(shí)際的行波管設(shè)計(jì)時(shí),特別是相速躍變的螺旋線行波管的設(shè)計(jì)時(shí)會(huì)產(chǎn)生較大的誤差。本文提出的改進(jìn)模型以能量守恒作為電子注和波之間的相互作用規(guī)范,所以在不計(jì)空間電荷力時(shí),高頻場(chǎng)的功率和電子注消耗的功率精確相等。用新模型的計(jì)算結(jié)果比用Rowe模型的更接近實(shí)際情況,特別是在變相速的設(shè)計(jì)中。

Abstract: Because of the nonconservation of energy in Rowe s modei for large signal interaction in TWT, Rowe s modei produces considerable error in TWT design, especially for a velocity-tapered 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. And all the results obtained with the new model a re in better agreement with the actual cases then those obtained with Rowe's model. -
