| 摘 要： | 托卡马克装置产生等离子体击穿的条件是在真空室区域中达到足够大的环电压以及尽可能大的零场区。在等离子体击穿阶段,由于EAST装置极向场线圈有较大的电流变化,会在真空室上感应出涡流,因此要考虑涡流对环电压和零场区的影响。主要介绍了数值法计算EAST装置真空室上涡流,只有正确计算涡流,才能为EAST实验提供了很好的参考价值。

| Abstract: | The condition that plasma breakdown on Tokmak is get enough high loop voltage and large null field region in the vacuum vessel area.During the period of the breakdown,because of a large current ramp created by the poloidal field coil,there will be inductive current on vacuum vessel.We must consider eddy have impact on loop voltage and null field region.This paper will mainly introduce numerical method to calculate eddy in vacuum vessel.Consequently,correct calculation of eddy in the vacuum vessel is important for EAST plasma breakdown. |
