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.
帶電粒子束在穿過加速結搆時激起的尾場，會導致束流能散和發射度的增大。
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.
直線加速器的重大改造旨在獲得高流強、小發射度和小能散的正負電子束，以滿足對撞機亮度提高兩個兩級的要求。
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.
本文將討論利用散束器減小RFQ加速器的束流能散，給出散束器作用後的能散分佈曲線方程。
