该计算程序用来产生速度渐变以提高耦合腔行波管的效率。用NASA多维大信号耦合腔行波管计算机代码编程,该程序使腔的周期逐步减少以满足线路相速与电子束速度间的规定关系的要求。计算机设计渐变的几种计算结果与三级跳变的实验藕合腔行波管进行了比较。对于给定的群聚相位曲线进行了研究,表明产生渐变后效率都提高了。计算的渐变结果在中心频率上的射频计算效率比三级跳变高出45％,在整个频带内至少高出37％。
This calculation procedure is used to produce a gradual speed ramp to increase the efficiency of the coupled cavity TWT. Using NASA multidimensional large signal coupled cavity TWT computer code programming, the program gradually reduces the cavity period to meet the required relationship between line phase velocity and electron beam velocity. Several computational results of the computer design gradients are compared with the experimental coupling TWTs with triple jump. For a given cluster phase curve were studied, showing that the efficiency of the gradient have increased. The computed gradient results in a 45% higher RF calculation efficiency at the center frequency than the triple jump and at least 37% over the entire frequency band.
