As to the electron linear accelerator, a large number of parameters, such as electron energy, electron beam current, microwave frequency and power, hole diameter of loading disks, length of accelerator tubes, Q of cavities, and conversion efficiency of the accelerator, are essential for its design, and the relations among these parameters are very much complicated.
In this article, charts which show numerical relations among these parameters are given and a nomogram of accelerator tubes is designed. These charts are prepared on the assumptions that: the beam loading characteristics can be represented as, dP/dz=-2IP-2iE, the group velocity is proportional to the fourth power of the ratio of hole diameter of disks to wave length, and the ratio of fundamental special waves to total waves in the electric field can be express as a function of hole diameter of disks.
In general, comparatively high conversion efficiency can be acquired at PL/PO=0.04.
