Developing advanced concepts for the extraction of negative ions from non-equilibrium plasmas

我在萨里大学完成了物理学学士学位，并在美国应用材料公司的离子束研究组进行了一年的实习。我在约克大学的博士研究重点是低温等离子体离子源的开发，这对磁约束聚变的中性束注入、电推进和先进制造等应用领域具有重要的应用价值。我们对这些源中负离子产生的物理学特别感兴趣，并将通过2D流体动力学模拟和非侵入性光学诊断相结合来研究这一问题。

I completed my BSc in Physics at the University of Surrey, undertaking a placement year in the ion-beam research group at Applied Materials, USA. My dissertation investigated implant induced defects in silicon carbide and the resultant changes to its material properties.My PhD research at York focuses on the development of low-temperature plasma ion sources, which are of significant interest for applications ranging from neutral-beam injection for magnetic confined fusion, electric propulsion and advanced manufacturing. We are particularly interested in the physics of negative ion production in these sources, and will investigate this via a combination of 2D fluid-kinetic simulations and non-invasive optical diagnostics.
