我们利用相对论性电离锋为等离子体中长质子束的自调制提供了不同的初始横向尾流场振幅。我们通过实验证明，在足够的初始振幅[≥(4.1±0.4)MV/m]下，沿束的调制相位在事件之间是可重复的，沿束有3%-7% （2π）的rms变化。在较低的初始振幅下，相位不能重现。我们观察到这两种制度之间的过渡。相重现性是加速确定性粒子外注的关键。
We use a relativistic ionization front to provide various initial transverse wakefield amplitudes for the self-modulation of a long proton bunch in plasma. We show experimentally that, with sufficient initial amplitude [≥(4.1±0.4) MV/m], the phase of the modulation along the bunch is reproducible from event to event, with 3%-7% (of 2π) rms variations all along the bunch. The phase is not reproducible for lower initial amplitudes. We observe the transition between these two regimes. Phase reproducibility is essential for deterministic external injection of particles to be accelerated.
