论文摘要
我们扩展了CERN ACELERATOR SCHOOL先前关于血浆Wakefield加速的材料的材料。在短而狭窄的束机构中，该材料着重于等离子体韦克菲尔德加速度。经过简短的介绍，我们描述了由束缚火车驱动的等离子体Wakefield加速。然后，我们尝试对一束较长时发生的束自调制的简单和直观的描述，并且在束宽时发生的当前细丝发生。自我调制是一种使用携带大量能量的现有束驱动等离子体韦克菲尔德的手段。当前的细丝不稳定性在横向分解之前可能会破坏Wakefields的生成和加速过程，这限制了粒子束的宽度。与先前的材料一样，我们显示了样本实验结果，这些结果表明已经在实验中观察到了许多物理学。
We expand on the material that was published in the previous Proceedings of the CERN Accelerator School on Plasma Wakefield Acceleration. The material focused on Plasma Wakefield Acceleration in the short, narrow bunch regime. After a brief introduction, we describe Plasma Wakefield Acceleration driven by a bunch train. We then attempt to give simple and intuitive descriptions of bunch self-modulation, occurring when the bunch is long, and of current filamentation, occurring when the bunch is wide. Self-modulation is a means to use existing bunches carrying large amounts of energy to drive plasma wakefields. Current filamentation instability imposes a limitation on how wide a particle bunch can be before transverse break-up may disrupt the wakefields generation and the acceleration process. As in the previous material, we show sample experimental results that demonstrate that much of the physics at play has been observed experimentally.
