Laser applications in Particle Accelerator Science

这个项目包括研究现代激光技术在粒子加速器科学中的应用，特别是针对新型加速器方法，如激光等离子体韦克菲尔德加速。这包括研究增加激光等离子体加速器的相互作用长度超过衍射极限的技术，通过使用高功率激光器产生场电离等离子体通道，用于引导激光脉冲以高重复率驱动大振幅尾场。它还包括研究相干组合技术，用于产生高平均和峰值功率的激光脉冲，用于利用大模面积光子晶体光纤激光放大器的高重复率加速。预计这项研究还将使基于激光的光束诊断应用于传统的加速器，作为开发改进的激光源的额外好处。

This project involves investigating the applications of modern laser technology to particle accelerator science, directed specifically at novel accelerator methods such as laser plasma wakefield acceleration. This includes research into techniques for increasing the interaction length of laser plasma accelerators beyond the diffraction limit by using high power lasers to generate field ionised plasma channels for guiding laser pulses to drive large amplitude wakefields at high repetition rates. It also encompasses research into coherent combination techniques for generating high average and peak power laser pulses for high repetition rate acceleration utilising large mode area photonic crystal fibre laser amplifiers. It is anticipated that this research will also enable the application of laser based beam diagnostics to conventional accelerators as an additional benefit of developing improved laser sources.
