本文主要内容包括耦合腔行波管大讯号速度渐变程序编制方法和编制过程的说明,以及利用本程序得到的一些计算结果的分析。 程序的编制基础是根据Comollg提出的理论和Vangham的以时间t为自变量的方法不同,它是以距离为自变量(其实Rowe提出的适用于一般行波管的大讯号方法也是这样),即沿管轴每前进△l距离(步长)后,求出各电荷盘到达这里的速度和时间,由这些速度和时间,就可获得在这儿截面上的感应电流;知道了腔内一些截面上的感应电流值,进而就可求出腔内的感应电压和腔口电压以及传输到下一腔的功率等。
The main contents of this paper include the description of the compilation process and the compilation process of large signal speed gradient of coupled cavity TWT, and the analysis of some calculation results obtained by this program. The procedure is based on the difference between Comollg’s theory and Vangham’s method of taking time t as an independent variable, which is based on distance as an independent variable (in fact, Rowe proposed a large signal method for general traveling-wave tubes) Along each tube axis forward △ l distance (step), find the charge tray to reach the speed and time here, from these speed and time, you can get here on the cross-section of the induced current; know some of the cross-section of the cavity Of the induced current value, and then you can find the cavity of the induced voltage and the port voltage and the power transmitted to the next cavity.
