在直线感应加速器中，使用的有束流位置、大小、半径等参数的诊断装置。

Beam diagnostic devices including beam position, beam magnitude and beam radius diagnostic devices is widely used in Linear Induction Accelerator(LIA).

然后讨论了影响粒子束传输的各种因素，包括粒子束类型、能量、束流、出口初始束半径以及散角等。

Then, the influences of the beam types, beam energy, beam current, initial radius and divergent angle on the beam propagation are discussed briefly.
