| 摘 要： | 直线加速器中电荷束团的非线性效应是导致束流发射度增长的一个重要原因。本文给出了直线加速器中几种常见的横向非均匀电荷密度分布的有限长空间电荷束团所具有的非线性自场能,得到了由束团非均匀电荷密度分布引起的发射度增长。

| Abstract: | The nonlinear space charge effect of bunched beam in Hnac is one of the important reasons that induces the emittance growth because of the conversion of the field energy to kinetic energy. In this paper, we have worked out the internal field energies associated with some transverse nonuniform space charge distributions of a bunched beam, such as Gaussian distribution, waterbag distribution, and parabolic distribution. And the emittance growth caused by these nonuniformities are obtained. |
