I am a Fusion CDT student supervised by Chris Murphy, and my research is on the use of laser wakefield accelerators as x-ray sources, which may have applications in inertial confinement fusion.My undergraduate degree was in Chemistry at Oxford University, which I completed in 2023. The 4th year of the degree was dedicated entirely to a research project, for which I worked on development of a laser-induced desorption source for photo-induced reaction dynamics experiments. I found I really enjoyed research and the academic environment, and this inspired me to apply for PhDs. In particular I discovered a passion for experimental physics, which, along with a longstanding interest in fusion energy, led to me choosing the Fusion CDT.In a laser wakefield accelerator a high intensity laser pulse generates a plasma wave as it propagates through a gas. Electrons can enter this plasma wave and be accelerated rapidly in the wake of the laser. Under the right conditions, these electrons can also oscillate and so produce synchrotron radiation in the x-ray region. The challenge I will be taking on is to optimise wakefield accelerators for generation of these x-rays, and thus create an x-ray 'laser'. It is already possible to generate high power x-ray laser pulses using x-ray free electron lasers (XFELs), but these require several kilometres of undulators, whereas laser wakefield accelerators may be able to generate the same laser powers over a few m

我是一名由Chris Murphy指导的聚变CDT学生，我的研究是使用激光尾流场加速器作为x射线源，这可能在惯性约束聚变中有应用。我的本科学位是牛津大学化学专业，于2023年完成。在学位的第四年，我完全投入到一个研究项目中，我的工作是开发用于光诱导反应动力学实验的激光诱导解吸源。我发现我真的很喜欢研究和学术环境，这激发了我申请博士学位。特别是，我发现了对实验物理的热情，以及对聚变能的长期兴趣，导致我选择了聚变CDT。在激光尾流场加速器中，高强度激光脉冲在气体中传播时产生等离子体波。电子可以进入等离子体波，并在激光的尾迹中迅速加速。在适当的条件下，这些电子也可以振荡，从而在x射线区域产生同步辐射。我将面临的挑战是优化尾流场加速器以产生这些x射线，从而创造出x射线“激光器”。利用x射线自由电子激光器（XFELs）产生高功率x射线激光脉冲已经成为可能，但这需要几公里的波动器，而激光尾流场加速器可能能够在几米内产生相同的激光功率
