摘要: 分析了周期性电容盘片加载的同轴线的传输特性，并将其应用于四分之一波长线谐振腔，利用传输线理论和数值模拟两种方法分析了这种腔体的谐振特性，得到了谐振频率、Q值与盘片半径、盘片个数间的关系，并论证了这种方法在减小腔体尺寸方面的可行性及在一台质子回旋加速器腔体中的应用。Abstract: In this paper, the transmission character of the periodically capacitor loaded coaxial transmission line is analyzed. We applied this kind of transmission line into the 1/4 wavelength transmission line cavity design. With both the transmission line theory and numerical simulation methods, we obtained the resonating frequency and Q factor as functions of the disk radius and the disk numbers. The possibility of this kind of met hod in decreasing the cavity's volume is discussed and its application in the design of the RF cavity of a proton cyclotron is presented as well in the paper.
