论文摘要
能量粒子（EP）驱动的不稳定性将在未来的燃烧等离子体中大大提高，因为与热等离子体相比，EP压力将非常大。了解EPS和大量等离子体的相互作用对于开发下一代融合设备至关重要。在这项工作中，将Jorek MHD代码扩展，以允许使用逼真的等离子体和EP参数在全f配方中使用各向异性压力耦合到蓝色背景，以模拟高EP压力的EP不稳定性。该代码首先是针对ITPA-TAE和基于实验的额外案例进行线性基准测试的，从而获得了与其他代码的良好一致性。然后，使用现实的EPS的非马克斯威尔分布，将其应用于ASDEX升级的高能颗粒压力排放，从而再现了实验观察到的不稳定性的方面。基于植入术，非线性应用程序是可能的，但需要专门的验证和验证才能进行未来的工作。
Energetic particle (EP) driven instabilities will be of strongly increased relevance in future burning plasmas as the EP pressure will be very large compared to the thermal plasma. Understanding the interaction of EPs and bulk plasma is crucial for developing next-generation fusion devices. In this work, the JOREK MHD code is extended to allow for the simulation of EP instabilities at high EP pressures using realistic plasma and EP parameter in a full-f formulation with anisotropic pressure coupling to the bluid background. The code is first benchmarked linearly for the ITPA-TAE as well as the experiment based AUG-NLED cases, obtaining good agreement to other codes. Then, it is applied to a high energetic particle pressure discharge in the ASDEX Upgrade tokamak using a realistic non-Maxwellian distribution of EPs, reproducing aspects of the experimentally observed instabilities. Non-linear applications are possible based on the implentation, but will require dedicated verification and validation left for future work.
