论文摘要
最近，在Lebedev等人的一篇论文中，证明了从驱动器束到血浆Wakefield Accelerator中的证人束的能量转移效率是由于证人束的BBU不稳定而有限的。据指出，效率 - 稳定关系是普遍的，因此应被视为基本限制。在本说明中，我们表明，短期韦克菲尔德的最新结果表明，应修改这种关系，并应重新考虑Lebedev等人对论文的结论。特别是，我们认为效率不稳定关系仅产生下限的效率，因此不会产生基本的限制。
Recently in a paper by Lebedev et al it was demonstrated that the efficiency of the energy transfer from the drive bunch to the witness bunch in the plasma wakefield accelerator has a limit due to the BBU instability of the witness bunch. It was stated that the efficiency-instability relation is universal and thus should be considered as a fundamental limit. In this note, we show that recent results on the short-range wakefields indicate that this relation should be modified and conclusions of the paper by Lebedev et al should be reconsidered. In particular, we argue that the efficiency-instability relation produces only the lower bound for efficiency and thus does not produce a fundamental limit.
