在自调制质子束驱动等离子体尾场加速的相关参数区域中研究了尾场振幅和相位对束流和等离子体参数的依赖性。尾场对小参数变化的敏感性揭示了实验结果的预期抖动水平。在所有参数中，等离子体密度最为突出，因为尾场相位对此参数极其敏感。对大变化的研究确定了限制参数空间不同部分中可实现的加速场的影响：尾场周期的非线性延长、驱动光束的电荷不足、发射驱动的光束发散以及等离子体离子的运动。
The dependence of wakefield amplitude and phase on beam and plasma parameters is studied in the parameter area of interest for self-modulating proton beam-driven plasma wakefield acceleration. The wakefield sensitivity to small parameter variations reveals the expected level of shot-to-shot jitter of experimental results. Of all the parameters, the plasma density stands out, as the wakefield phase is extremely sensitive to this parameter. The study of large variations determines the effects that limit the achievable accelerating field in different parts of the parameter space: nonlinear elongation of the wakefield period, insufficient charge of the drive beam, emittance-driven beam divergence, and motion of plasma ions.
