Plasma wakefield acceleration at SLAC FACET-II

该项目围绕着即将在SLAC FACET-II上进行的等离子体韦克菲尔德加速器（PWFA）实验，这些实验是在E-310：特洛伊木马计划和未来潜在的PWFA-FEL设计的背景下进行的。该项目的动机是从E210实验在FACET和等离子体光阴极技术的前景。该项目将推动等离子体韦克菲尔德加速和等离子体光电阴极的高亮度电子束产生，并将开发出在离开等离子体阶段后提取、捕获和传输此类电子束的解决方案，然后将研究利用此类电子束为下一代自由电子激光器提供动力的潜力。这种电子束的发射率和亮度可以允许在紧凑的设置中实现硬x射线区域中的相干自由电子激光器，这可能会彻底改变光子科学的前景。该项目与STFC“PWFA-FEL”项目“PWFA驱动的FEL在CANUA的探索性研究”一致，该项目与ASTeC，SLAC和UCLA合作。

This project revolves around upcoming plasma wakefield accelerator (PWFA) experiments at SLAC FACET-II in context of the E-310: Trojan Horse programme and the design of a potential future PWFA-FEL. The project is motivated by results from the E210 experiments at FACET and prospects of the plasma photocathode technology. The project will push plasma wakefield acceleration and ultrahigh brightness electron beam production from a plasma photocathode, and will develop solutions for extraction, capture, and transport of such beams after leaving the plasma stage, and will then investigate the potential of exploiting such electron beam to power next-generation free electron lasers by them. The emittance and brightness of such electron beams may allow to realize coherent free-electron lasers in the hard x-ray region in compact setups, which could revolutionize the photon science landscape. The project is aligned with the STFC "PWFA-FEL" project "Exploratory study of PWFA-driven FEL at CLARA" in collaboration with ASTeC, SLAC and UCLA.
