beam envelope

基本解释

In this paper, we propose to measure the beam envelope by a thin plastic scintillation filament.
本文提出用闪烁丝测量束流包络，从而求出粒子流真实发散度的方法。
A calculation model of accelerator beam envelope has been developed. It can predict beam envelope in linear induction accelerator from the injector to the final focus region.
给出的直线感应加速器束输运的计算模型，能够计算束流从注入器经加速器直到最后聚焦的束包络。
In one-dimension simulation, the approach taken is a hybrid model where the ions are treated as distinct particles in one-dimension while the electron beam is treated using the beam envelope equation.
在一维模拟中，采用混合模型研究离子噪声，用包络方程描述电子束的，用离散的宏粒子模型描述离子。
