论文摘要
如果带电的粒子束在等离子体 - 空白边界附近传播,它会激发表面波并经历由边界引起的力。对于线性响应的等离子体和超相关束,计算激发场的空间分布,并通过基本功能近似施加在短而狭窄的束上的力。如果束在真空中,该力将束吸引到边界,否则将其排斥。还有其他力量的组成部分。
If a charged particle bunch propagates near a plasma-vacuum boundary, it excites a surface wave and experiences a force caused by the boundary. For the linearly responding plasma and ultra-relativistic bunch, the spatial distribution of excited fields is calculated, and the force exerted on a short and narrow bunch is approximated by elementary functions. The force attracts the bunch to the boundary, if the bunch is in the vacuum, and repels otherwise. There are also additional focusing and defocusing components of the force.
