Study of plasma dynamics and development of simulator by integrated models

为了控制托卡马克聚变反应堆中等离子体的非线性和复杂性，建立了托卡马克等离子体主要物理元素的理论模型。通过对这些模型的集成，生成了能够统一处理各个物理模型的集成仿真代码。在该代码中，以核心等离子体的热和粒子输运代码作为集成代码的平台，并将加热和电流驱动、MHD稳定性、分流、高能粒子效应等物理模型耦合到平台代码中。利用本文开发的集成代码，通过与实验结果的对比，验证了集成模型的正确性。阐明了核心等离子体的复杂现象，并对核心等离子体的控制提出了指导意见。该集成代码有助于构建等离子体模拟器的原型版本，以补充托卡马克聚变反应堆的实际放电。

In order to control the plasma in the tokamak fusion reactor with a non-linearity and complexity, theoretical models of the major physical elements of the tokamak plasma are developed. By the integration of these models, the integrated simulation code that can handle consistently each physical model is produced. In this code, the heat and particle transport code of the core plasma is used as a platform for the integrated code, and the physics models of heating and current drive, MHD stability, diverter, high-energy particles effects are coupled to the platform code. Using the integrated code developed here, the integrated model is validated by the comparison with the experimental result. Complex phenomena of core plasma are elucidated, and guides toward the control of the core plasma are indicated. The integration code is contribute to the construction of a prototype version of the plasma simulator that complements the actual discharge of tokamak fusion reactor.
