摘要
初步研究了环径比接近2的托卡马克堆芯等离子体的基本特征。这类位形具有非常好的使磁流体稳定的特性,可以基本排除等离子体破裂不稳定性。从H模约束要求和氘氚燃烧实验出发,讨论了相关的基本问题:比压极限和密度极限、基本等离子体参数间的调整、氘氚自持燃烧条件等。参数选取的基本依据是ITER和ITER FEAT的设计经验。
The core plasma characteristics of a tokamak reactor with aspect ratio near 2 are studied. An excellent feature of this kind of plasma configuration is the very good stability merit against the plasma disruptions. Starting from the Hmode confinement scaling and requirements of deuteriumtritium burning experiments, some basic issues are considered such as the density limit, the beta limit, the adjustments of basic parameters, the selfsustainable burning condition, etc. Experience of the ITER and ITERFEAT designs is the benchmark of our study.
