| 摘 要： | 根据Shafranov电流密度矩理论，给出了用可移动电流丝方法重建HL-2A装置等离子体边界的具体计算方法，研究了用可移动电流丝方法(VCF法)重建边界的可行性.VCF法与固定电流丝方法(FCF法)和有限电流元法(FCE法)相比，最大的优点就是用1—3个可移动电流丝就可以准确地重建位置和小半径快速变化的等离子体位形，这正好弥补了FCF法的不足.将可移动电流丝方法和FCF法相结合，可以实现全程等离子体放电的边界实时显示和等离子体的位形控制.

| Abstract: | Based on the Shafranov current moment theory, reconstruction of the plasma boundary in HL-2A is studied by using the movable current filament (VCF) method. Compared with the fixed current filament (FCF) method and the finite current element (FCE) method that we've used before, this method has the advantage of accurately rebuilding the fast evolving plasma boundary by using only 1—3 filaments, which offsets the drawbacks of the FCF and the FCE methods. Combining the movable current filament method with the FCF or the FCE method, the plasma boundary can be displayed in real time and the plasma shape can be controlled during the whole discharge process. |
