Characterisation of ion and electron scale electromagnetic turbulent transport in MAST. Upgrade and STEP pedestals

我于2021年毕业于华威大学数学和物理学专业，在那里我对流体力学产生了兴趣，随后又对等离子体物理产生了兴趣。我对湍流以及与其精确定义和建模相关的困难特别感兴趣。我的本科项目涉及研究等离子体交换模型中从湍流状态到层流状态的转变。我对等离子体物理的兴趣促使我在2022-23年在约克大学攻读硕士学位，我在那里的最后一个项目涉及将不确定量化应用于等离子体细丝模型的参数空间，以研究粒子通过托卡马克刮离层的传输。Fusion代表着一个机会，既可以从事我感兴趣的学术领域，又可以为一项具有积极造福社会潜力的技术的发展做出贡献。我的研究将在CCFE进行，由约克大学的David Dickinson和英国AEA的Ben Chapman-Oplopoiou监督。该项目的目的是通过使用基因回转动力学代码来了解热和粒子通过球形托卡马克基座区域的湍流传输。来自MAST和MAST-U的数据表明，底座区域的湍流主要是由某些电磁微不稳定性驱动的，我们希望利用GENE进行比较，从而表征主要的传输机制。一旦我们了解了不同的不稳定性如何影响基座运输，我们的目标是将这些发现应用于对未来阶梯基座的运输预测。

I graduated from Warwick University in Maths and Physics in 2021, where I acquired an interest in fluid dynamics and, subsequently, plasma physics. I am particularly interested in turbulence and the difficulties associated with its precise definition and modelling. My undergraduate project involved investigating transitions from turbulent to laminar states in the plasma interchange model. My interest in plasma physics led me to study Fusion Energy for my MSc at University of York in 2022-23 and my final project there involved applying uncertainty quantification to the parameter space of a plasma filament model to investigate particle transport through tokamak scrape-off layers. Fusion represents an opportunity to simultaneously engage in my areas of academic interest and contribute to the development of a technology with the potential to actively benefit our society.My research will be based at CCFE, supervised by David Dickinson from University of York and Ben Chapman-Oplopoiou from UKAEA. The aim of the project is to understand the turbulent transport of heat and particles through the pedestal region of spherical tokamaks by using the GENE gyrokinetic code. Data from MAST and MAST-U indicates that turbulence in the pedestal region is primarily driven by certain electromagnetic microinstabilities which we hope to compare using GENE and thereby characterise the dominant transport mechanisms. Once we have an understanding of how different instabilities affect pedestal transport, we aim to apply these findings to make transport predictions for future STEP pedestals.
