This paper presents a method of calculation of the noise figure of power travelling wave tubes which employ a conical Pierce gun to produce the electron beam. Under the assumption that the electron beam is single-velocity and one-dimensional, the transmission equation of space charge wave set up in the conical electron beam is derived and the process of noise impedance transformation is obtained. Theoretical calculations show that changing the convergence angle, the radius of curvature, the anode voltage and the length of the drift region can reduce the noise figure of a power travelling wave tube. Theoretical results presented in this paper are examined with the experimental noise figure values of a few of practical tubes.

本文给出了采用球形收敛枪的功率行波管噪声系数的计算方法。在单速、一维假定下,推导了球形收敛电子注上的空间电荷波传播方程和噪声阻抗的变换过程。计算表明:改变收敛角、阴极曲率半径、阳极电压及漂移区长度等,可以使功率行波管获得较低的噪声系数。通过几个实际管子噪声系数的测量,对本文所得的结果进行了验证。
