The interaction of intense laser pulses with matter is opening up new frontiers in physics via the production of extreme pressures, temperatures and intense electric and magnetic fields. This is leading to the use of high power laser radiation for exploring the properties of hot dense matter, the production of high energy particles and radiation, and the development of schemes to generate energy by inertial confinement fusion. These advances are driven by rapid developments in ultrashort pulse laser technology which have enabled new regimes in laser power and intensity to be reached. With the advent of multi-petawatt power lasers (e.g. the upgrade project to the Vulcan laser at the UK's Central Laser Facility will deliver 10 petawatt pulses by 2013-2014) exotic new plasmas with unique properties are accessible, including strongly relativistic dense plasma. The principal aims of this proposed project are to investigate the fundamentals of laser-solid interactions in strongly relativistic plasmas - a regime of laser-plasma interactions not previously accessible - and to harness predicted promising new ion acceleration schemes achievable with ultrahigh intensity laser pulses. This will advance our understanding of ultrahigh intensity laser solid interactions and may lead to new applications of laser-plasma-based particle and radiation sources. The proposal involves the development and application of new techniques on experiments using some of the highest power laser systems available.

强烈的激光脉冲与物质的相互作用是通过产生极高的压力，温度以及强烈的电场和磁场来打开物理领域的新边界。这导致使用高功率激光辐射来探索热量密集物质的性质，高能颗粒和辐射的产生以及通过惯性限制融合产生能量的方案的发展。这些进步是由超短脉冲激光技术的快速发展所驱动的，这使得能够达到激光功率和强度的新制度。随着多人发电机激光器的出现（例如，到2013 - 2014年，英国中央激光器设施的Vulcan Laser的升级项目将提供10个Petawatt Pulses）奇异的新等离子体，具有独特的独特属性，包括非常相对的浓密等离子。该拟议项目的主要目的是研究强烈相对论的等离子体中激光 - 固体相互作用的基本原理 - 激光 - 铂相互作用的制度 - 以前无法访问的激光 - 超级相互作用 - 并预测有希望的新离子加速度方案可通过Ultrimaigh强度激励激光激光脉冲达到可实现的新离子加速度。这将促进我们对超高强度激光固体相互作用的理解，并可能导致基于激光 - 等离子的粒子和辐射源的新应用。该提案涉及使用一些可用的功率激光系统在实验上开发和应用新技术。
