报告摘要：
基于激光等离子体和粒子束等离子体相互作用的高能加速器是加速器领域的一颗新星。这种技术最突出的特点是拥有超过传统加速器近万倍的超高加速梯度。在过去的近十年里，一系列重要的理论模拟和实验研究的突破使得这个研究领域的面貌发生的革命性的变化。在这个报告里，我将简要的介绍这个领域的发展概况和研究现状，并结合自己的研究经历，详细的介绍一个重要的Regime（the Blowout Regime）和与之相关的理论，模拟和实验结果。
The field of Plasma based acceleration (including LWFA and PWFA) has experienced amazing development in the past decade. During this period of time,many important progress on theory, simulation and experiment in both LWFA and PWFA have been made. In this talk, I will introduce you some of these progress, with a focus on the research that I have actively engaged in. The theoretical topics I will cover are fundamental issues in this field, including the nonlinear wake excitation, beam loading, hosing instability, multi-dimensional injection and phenomenological framework and scaling of LWFA in the blowout regime. The computational topics I will cover include the full scale 3D modeling of LWFA and PWFA from GeV to TeV stage by large scale parallel PIC simulations. The experimental topics I will cover include both PWFA and LWFA. For PWFA, a series of experiments at SLAC will be discussed, and an experiment that demonstrated energy doubling of the 42GeV electron beam will be highlighted. For LWFA, a series of experiments at UCLA and LLNL will be discussed, including short pulse laser self-guiding, injection threshold, ionization induced injection and GeV level electron beam generation in the self-guided blowout regime with both self and ionization induced injection.
