论文摘要
发射率是一种光束质量，对于高级加速器的许多未来应用至关重要，例如紧凑的自由电子激光器和线性胶合器。在本文中，我们回顾了在内部和外部加速器阶段保留加速期间横向发射率的挑战。发射量的来源范围从横向韦克菲尔德引起的空间电荷和不稳定性，无论中等加速器方案中，无论媒介或驱动器类型如何，都可以发生在等离子体加速器方面的来源，而不是等离子体加速器的来源，例如不匹配，不匹配，离子运动，离子运动，coulomb运动，coulomb散射，阶段之间的色度等等。
Emittance is a beam quality that is vital for many future applications of advanced accelerators, such as compact free-electron lasers and linear colliders. In this paper, we review the challenges of preserving the transverse emittance during acceleration, both inside and outside accelerator stages. Sources of emittance growth range from space charge and instabilities caused by transverse wakefields, which can occur in any advanced accelerator scheme regardless of medium or driver type, to sources more specific to plasma accelerators, such as mismatching, misalignment, ion motion, Coulomb scattering, chromaticity between stages, and more.
