摘要:

掌握如何安全处理等离子体-材料相互作用(Plasma-Material Interaction, PMI)是核聚变能商业化进程中的一项关键挑战。在这一领域,线性等离子体装置是理想的实验测试平台,而数值程序则发挥着至关重要的补充作用。本文对GyM线性装置中与PMI相关的氦等离子体实验放电开展了数值研究,研究中耦合使用SOLPS-ITER和ERO2.0程序,分别用于生成等离子体背景和研究材料侵蚀,旨在辅助解读现有实验数据集并对其进行补充。在等离子体方面,模拟得到的分布曲线经实验数据验证,可提供符合实际的等离子体背景,且本研究首次在SOLPS模拟中评估了氦亚稳态的作用。在材料方面,研究探究了模拟区域内引入样品台带来的侵蚀与沉积效应,此次还将真实不锈钢成分作为壁材料纳入了考量。

英文摘要:

Learning how to safely handle Plasma-Material Interaction (PMI) is a key challenge towards the commercialisation of energy from nuclear fusion. In this respect, linear plasma devices are ideal experimental testbeds, and numerical codes play a crucial complementary role. In this paper, a numerical investigation of PMI-relevant helium plasma experimental discharges in GyM linear device is presented, in which SOLPS-ITER and ERO2.0 codes are coupled for plasma background generation and material erosion investigation respectively, with the aim to support the interpretation and complement the available experimental dataset. On the plasma side, simulated profiles are validated against experimental data to provide a realistic plasma background, and the role of He metastable states is assessed for the first time in SOLPS simulations. On the material side, the erosion and deposition effects due to the introduction of the sample-holder in the simulation volume are investigated, now considering also the real stainless steel composition as wall material.
