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.

融合研究人员现在正在努力建立世界上第一个核反应堆。仍然存在许多问题 - 其中之一是缺乏对托卡马克（Tokamak）分离地区血浆化学的完全了解。对Tokamak区域内的气态过程的透彻理解对于工作Tokamak至关重要，因为现代的磁Tokamak构型导致转移区域的大点热负载，而转移区域内的化学过程会散发此热量。我们可以从分离器中获得SpectRoscic Balmer和Fulcher系列数据。但是，我们需要一个化学通知的过程的模型，才能有意义地绘制这些数据。贝叶斯数学可用于提供这种化学模型。该博士学位项目旨在使用Culham实验提供的Balmer和Fulcher线数据来开发更好的化学模型。开发出更好的化学模型后，用于预测Tokamak刮擦层中的物理过程的代码SOLP将在磁性和热中链接到分流器。
