反应堆级聚变等离子体特性及理论方法的研究

Main achievements are summarized in 11 papers, in which 8 have been published and another 3 to be published. These include: an anylytical appraoch to the tokamak LH wave is given and the mechanism for density limit inLHCD experiments is clarified: the mode conversion of slow wave to the fast wave due to toroidicity effect;The propagation and absorption of O-mode ECR wave is studied, the basic characteristic of the weakly relativistic damping is clarified; The ideal MHD theory in the shear Alfvenic approximation is simplified by an uniform description and starting equations for the global and local modes are given. The equilibrium equation with toroidal flow is nalytically solved and the effect of this flow is made clear that to locally change Shafranov shift and magnetic well. Equilibrium sustained by large fraction of bootstrap current is analyically solved, having the merit without setting an target quilibrium first and to align the current profile iteratively as in previous methods. The A=2 burning plasma is preliminarily studied which is an important blank in magnetic fusion research. The toroidicity effect on the edge safety factor and shear are made clear, implying that the small aspect ratio tokamak is disruption free and being able to maintain high beta plasma.

堆级磁约束聚变等离子体特性，包括高约束位形，近临界（密度和比压）条件下特性，长脉冲Ｈ模，高能成分效应等内容及理论方法的研究，是当前和今后国际研究焦点，也与国内装置建设和实验规划协调。本项目既重视物理内容，也重视理论方法，着眼较长时期，因此既与大装置实验配合，又可使今后年轻学者的研究具有一个高起点。.
