论文摘要
面包不稳定性为基于等离子体的加速器概念带来了可行性风险。我们表明，线性状态下的梁簇的增长率（这与使用长驱动器的概念有关）是质心扰动波长的函数。我们证明了如何通过在不稳定性的早期充分破坏血浆反应来湿润质心振荡。我们还开发了一种新的理论模型，用于早期的羊毛发展。这些发现对不稳定性增长率的一般控制有影响。
The hosing instability poses a feasibility risk for plasma-based accelerator concepts. We show that the growth rate for beam hosing in the linear regime (which is relevant for concepts that use a long driver) is a function of the centroid perturbation wavelength. We demonstrate how this property can be used to damp centroid oscillations by detuning the plasma response sufficiently early in the development of the instability. We also develop a new theoretical model for the early evolution of hosing. These findings have implications for the general control of an instability's growth rate.
