项目摘要

Laser-driven ultrafast sources of energetic radiation will have a transformative impact in numerous industrial and scientific areas over the next decade. At the focus of an ultra-high power laser, extremely large electric fields can be used to accelerate charged particles to 100's MeV energies and produce bright, highly directional hard X-ray pulses. With the advent of new diode pumping technology, such sources will be able to be delivered at 10's Hz (x100 faster than today's typical machines) over the next few years and this opens the way for new and novel applications of such sources. This project will develop our understanding of the laser-plasma interaction to enable brighter and better conversion into these new and novel X-ray sources, specifically for the application of penetrating imaging for defence. This project will also develop and apply ultrafast detectors matched to the new time-resolved imaging capability of these unique sources (typically of sub ps duration). The objectives include simulation, modelling and experimentally evaluating such new detector classes to deliver unprecedented highly penetrating imaging capability. The student is registered at the Physics Department at the University of Strathclyde and based primarily at the Central Laser Facility, Oxfordshire where they have access to specialist experimental equipment including the Vulcan and Gemini high power lasers and several large high performance computers, and at Dstl (Defence Science and Technology Laboratory) where they will be trained in Monte Carlo modelling. The project aligns to EPSRC's Global Uncertainties (Terrorism) theme and the Plasma and Laser research area

激光驱动的超快高能辐射源将在未来十年内对许多工业和科学领域产生变革性影响。在超高功率激光器的焦点处，可以使用极大的电场将带电粒子加速到100 MeV的能量，并产生明亮，高度定向的硬X射线脉冲。随着新的二极管泵浦技术的出现，这种源将能够在未来几年内以10 Hz（比今天的典型机器快100倍）的速度提供，这为这种源的新的和新颖的应用开辟了道路。该项目将发展我们对激光-等离子体相互作用的理解，以实现更明亮，更好地转换为这些新型X射线源，特别是用于国防穿透成像的应用。该项目还将开发和应用与这些独特源（通常为亚ps持续时间）的新时间分辨成像能力相匹配的超快探测器。其目标包括模拟、建模和实验评估这些新的探测器类别，以提供前所未有的高穿透成像能力。该学生在斯特拉斯克莱德大学物理系注册，主要位于牛津郡的中央激光设施，在那里他们可以使用专业实验设备，包括Vulcan和Gemini高功率激光器和几台大型高性能计算机，并在DSTL（国防科学与技术实验室）接受蒙特卡洛建模培训。该项目与EPSRC的全球反恐主题以及等离子体和激光研究领域保持一致
