Expedited Award for Novel Research: Theory and Computer Simulation of a Plasma-Driven Inverse Free-Electron Laser

这项提议是作为小说研究快速奖提交审议的。PI建议从理论上研究一种利用激光-等离子体相互作用来加速高能粒子的新方法。目前，文献中有两种激光-等离子体方法，即拍波加速器和反向自由电子激光。Bobin最初提出的在IFEL中引入等离子体的基本思想可以显著改善加速度梯度。PI认为Bobin的理论计算远远不完整或不可靠，特别是认为缺乏对其运行至关重要的相位信息处理。他建议对等离子体增强概念进行理论建模和计算机模拟，这在很大程度上是基于采用加州大学洛杉矶分校提供的粒子代码的新想法。该项目是及时的，因为它可以作为布鲁克海文国家实验室计划的未来先进加速器概念的原则验证实验。

This proposal was submitted for consideration as an Expedited Award for Novel Research. The PI has proposed to study theoretically a novel variant to high-energy particle acceleration utilizing laser- plasma interactions. Currently, two laser-plasma approaches are in the literature, the beat-wave accelerator and the inverse free- electron laser. The basic idea originally suggested by Bobin of introducing a plasma into the IFEL could improve significantly the acceleration gradient. The PI considers Bobin's theoretical calculations as far from complete or reliable and, in particular, feels that a treatment of phase information is lacking that is crucial to its operation. He proposes to carry out theoretical modeling and computer simulation of the plasma-enhanced concept, based in large degree on new ideas of adapting particle codes available from UCLA. The project is timely as it could serve as proof-of-principle experiments for future advanced accelerator concepts planned at the Brookhaven National Laboratory.
