beam envelope

基本解释

In this paper, we propose to measure the beam envelope by a thin plastic scintillation filament.
本文提出用閃爍絲測量束流包絡，從而求出粒子流真實發散度的方法。
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.
給出的直線感應加速器束輸運的計算模型，能夠計算束流從注入器經加速器直到最後聚焦的束包絡。
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.
在一維模擬中，採用混郃模型研究離子噪聲，用包絡方程描述電子束的，用離散的宏粒子模型描述離子。
