长质子或电子束的受控自调制是等离子体尾波场加速的新趋势，这为模拟程序提出了新的目标。长相互作用长度(几十米)，长光束(高达数百个等离子体波周期)，等离子体离子的运动，以及对流体近似的违反，这些因素使得问题对于通用代码来说过于繁重。只有专门的代码才能解决真实几何中的这个问题。我们描述了最近对LCODE程序的升级，该程序能够模拟长密度质子束，并报告了在EACKE计划背景下质子束-等离子体相互作用的数值研究结果。
Controlled self-modulation of long proton or electron beams is a new trend in plasma wakefield acceleration which sets a new goal for simulation codes. Long interaction lengths (tens of meters), long beams (up to hundred of plasma wave periods), motion of plasma ions, and violation of fluid approximation are factors that makes the problem too heavy for general purpose codes. Only specialized codes can attack this problem in real geometry. We describe recent upgrades of the code LCODE which enabled simulations of long dense proton beams and report results of numerical studies of proton beam-plasma interaction in the context of AWAKE project.
