beam energy spread

基本解释

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。
The BEPCⅡ injector linac upgrade aims at having higher beam energy with smaller beam emittance and energy spread to meet the colliding luminosity upgrade by two orders of magnitudes higher.
直线加速器的重大改造旨在获得高流强、小发射度和小能散的正负电子束，以满足对撞机亮度提高两个两级的要求。
In this paper reduction of the beam energy spread of RFQ for nuclear physics bydebuncher is discussed. The equation of the curve of the beam energy spread afterdebuncher effect is presented.
本文将讨论利用散束器减小RFQ加速器的束流能散，给出散束器作用后的能散分布曲线方程。
