beam energy spread的意思|示意

When charged particle beams traverse in an accelerating structure, the excited wake fields may dilute the beam energy spread and emittance.

带电粒子束在穿过加速结构时激起的尾场，会导致束流能散和发射度的增大。

Objective:To derive the energy spread function of the electron pencil beam model from the measured beam profiles.

目的：探讨用离轴比曲线分析电子束照射野笔形束模型能量展宽函数的方法。

The configuration keeps the excellent achromatic and focusing properties even for charged particle beam with very large energy spread.

该系统具有较好的消色差特性和聚焦特性，能量范围宽，特别适用于能散较大的带电粒子束流的传输。
