Plasma wakefield acceleration at SLAC FACET-II

该项目围绕着在E-310：特洛伊木马程序的背景下即将在SLAC第二方面进行的等离子体尾流加速器(PWFA)实验，以及未来可能的PWFA-FEL的设计。该项目是基于E210方面的实验结果和等离子体光电阴极技术的前景而提出的。该项目将推动等离子体尾场加速和从等离子体光电阴极产生超高亮度电子束，并将开发解决方案，在离开等离子体阶段后提取、捕获和传输此类电子束，然后将研究利用这些电子束为下一代自由电子激光器提供动力的潜力。这种电子束的发射度和亮度可能允许在紧凑的装置中实现硬x射线区域的相干自由电子激光，这可能会彻底改变光子科学的格局。该项目与STFC“PWFA-FEL”项目“在克拉拉对PWFA驱动的自由电子激光的探索性研究”保持一致，并与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.
