This award will support basic research with three-dimensions simulations including full-scale modeling of ongoing or planned experiments with the primary tool being three-dimensional particle-in-cell (PIC) simulations. The simulations provide a test bed for theoretical ideas and, once validated, a method to guide experiments. High-fidelity full-scale modeling will provide a means to extrapolate parameters into regimes that will not be accessible to experiments for years to come. The research group will exploit an unmatched array of PIC codes and data analysis tools, a detailed understanding of the key PWFA experiments, and close connections to experimental programs within the US and abroad. In particular, the research will investigate the following 1. Explore the physics necessary to make a compact LWFA or PWFA stage. 2. Explore the physics necessary to make a linear collider based on wakefield stages a reality. 3. Carry out full-scale 3D PIC simulations of beam and laser-plasma experiments, e.g., at UCLA, SLAC, the L'OASIS lab at LBL, the Hercules laser at Michigan, the Texas Petatwatt laser, and RAL (England). 4. Continue to develop the PIC infrastructure including reduced PIC algorithms. 5. Continue to develop predictive theory and scaling laws. The High Energy Density Science (HEDS) area of intense laser and beam-matter interactions has an impact on plasma-based acceleration and radiation sources, and even on the fast ignitor fusion concept. Compact particle accelerators might eventually have an impact on particle physics, material science, structural biology, medicine, fusion research, and transmutation of nuclear waste. The students and post-doctoral researchers trained under this grant will be part of the twenty-first century work force in computational science and engineering as well as experts in HEDS. UCLA codes and algorithms are being used by other groups throughout the world. This grant supported a female graduate student. An effort is underway to share this group's parallel simulation codes with Florida A&M, a historically black university.

该奖项将支持三维模拟的基础研究，包括正在进行或计划进行的实验的全尺寸建模，主要工具是三维粒子模拟（PIC）。 这些模拟为理论思想提供了一个测试平台，一旦得到验证，就可以指导实验。 高保真全尺寸模型将提供一种手段，将参数外推到未来几年无法进行实验的状态。该研究小组将利用一系列无与伦比的PIC代码和数据分析工具，详细了解关键PWFA实验，并与美国和国外的实验项目密切联系。特别是，研究将调查以下1。探索制作紧凑型LWFA或PWFA载物台所需的物理原理。 2.探索必要的物理学，使线性对撞机的基础上韦克菲尔德阶段的现实。 3.对光束和激光等离子体实验进行全尺寸3D PIC模拟，例如，在加州大学洛杉矶分校，SLAC，LBL的L'OASIS实验室，密歇根州的大力神激光器，德克萨斯州的Petatwatt激光器和RAL（英格兰）。 4.继续开发PIC基础设施，包括简化的PIC算法。 5.继续发展预测理论和标度律。 高能量密度科学（HEDS）领域的强激光和束物质相互作用对基于等离子体的加速和辐射源，甚至对快速点火器聚变概念产生了影响。紧凑型粒子加速器最终可能会对粒子物理学、材料科学、结构生物学、医学、聚变研究和核废料的嬗变产生影响。根据这项补助金培训的学生和博士后研究人员将成为计算科学和工程领域的21世纪世纪劳动力以及HEDS专家的一部分。加州大学洛杉矶分校的代码和算法正在使用的其他团体在世界各地。 这笔赠款资助了一名女研究生。一个正在努力与佛罗里达A M，一个历史上的黑人大学分享这个小组的并行模拟代码。
