结果表明，电子或正电子共线注入自调制粒子束的尾波场是可能的，并确保高能量增益。见证光束必须与驱动器尾部共同传播，因为那里的等离子体波相速度可能超过光速，而光速是有效加速所必需的。如果见证光束有许多尾场周期长，则捕获的电荷会受到光束加载效应的限制。最初的正电子捕获效果更好，但在加速阶段，相当一部分正电子从波中丢失。为了有效捕获电子，等离子体边界必须清晰，密度过渡区域短于几厘米。正电子不易受初始等离子体密度梯度的影响。
It is shown that co-linear injection of electrons or positrons into the wakefield of the self-modulating particle beam is possible and ensures high energy gain. The witness beam must co-propagate with the tail part of the driver, since the plasma wave phase velocity there can exceed the light velocity, which is necessary for efficient acceleration. If the witness beam is many wakefield periods long, then the trapped charge is limited by beam loading effects. The initial trapping is better for positrons, but at the acceleration stage a considerable fraction of positrons is lost from the wave. For efficient trapping of electrons, the plasma boundary must be sharp, with the density transition region shorter than several centimeters. Positrons are not susceptible to the initial plasma density gradient.
