Fusion researchers are now working towards building the world's first nuclear reactor. Many issues remain - one of them being a lack of a complete understanding of the plasma chemistry in the divertor region of the tokamak. A thorough understanding of the gaseous processes within the tokamak region is crucial to a working tokamak as modern magnetic tokamak configurations lead to large point heat loads in the divertor region and chemical processes within the divertor region dissipate this heat.We can obtain spectroscopic balmer and fulcher line data from the divertor. However, we need a model of the processes informed by chemistry to be able to meaningfully plot this data. Bayesian mathematics can be used to provide this chemical model.This PHD project aims to use the balmer and fulcher line data provided by experiments at Culham to develop a better chemical model. When a better chemical model has been developed, the code, SOLPS, used to predict physical processes within the Scrape Off Layer of the tokamak which is linked magnetically and thermally to the divertor will be updated.

核聚变研究人员正在努力建造世界上第一个核反应堆。许多问题仍然存在，其中之一是缺乏对托卡马克偏滤器区域等离子体化学的完整理解。一个全面的了解托卡马克区域内的气体过程是至关重要的工作托卡马克作为现代磁托卡马克配置导致大的点在偏滤器区域的热负荷和偏滤器区域内的化学过程消散这种热量。我们可以从偏滤器获得光谱巴耳末和富尔彻线数据。然而，我们需要一个由化学告知的过程模型，以便能够有意义地绘制这些数据。贝叶斯数学可以用来提供这种化学模型。这个博士项目的目的是利用在卡勒姆实验提供的巴耳末和富尔彻线数据来开发一个更好的化学模型。当一个更好的化学模型已经开发出来，代码，SOLPS，用于预测物理过程内的托卡马克的磁和热连接到偏滤器的刮除层将被更新。
