| 摘 要： | 在双粒子模型假定下讨论了短程束流尾场效应。该效应在脉冲积分近似下,等价于在消色差系统中央平面上对束团施加一个附加的纵向和横向动量增量。通过传输矩阵变换运算.推得了包括束流尾场引起的束流纵向和横向位移在内的束流纵向和横向传输表达式,藉以考察束流尾场效应对消色差系统的影响。

| Abstract: | Short-range beam wakefield effects are discussed in this paper by means of a two-particle model, in which the front and tail of a beam bunch are represented with two macroparticles. The wakefield effects induced by the front particle, using impulse approximation, are equivalent to additional momentum increases of the tail particle at the midplane of achromatic system. The transport formulae taking account of the transverse displacement and longitudinal displacement caused by the wakefield effects have been derived for studying the effects in achromatic system. |
