Within the region where the ITB locates, the plasma pressure has a large gradient while the magnetic shear s has a minimum so that within and near the ITB, the absolute value of the shear is very low. Physics involved is plentiful, from the macroscopic （ MHD ） stability, to the suppression of microscopic instabilities thought to be responsible for anomalous transport. The treatment of very low shear also poses some theoretical difficulties.展开更多
研究了在JT-60U运行参数下的α诱发的环向阿尔芬本征模(αTAE),由其实验数据得到了s和α的径向剖面(s=rdq/qdr,2 q R d/dr)。发现存在α极大值,尤其是在反剪切等离子体和高性能位形下。这证实了托卡马克中存在αTAE的全域捕获条件。在...研究了在JT-60U运行参数下的α诱发的环向阿尔芬本征模(αTAE),由其实验数据得到了s和α的径向剖面(s=rdq/qdr,2 q R d/dr)。发现存在α极大值,尤其是在反剪切等离子体和高性能位形下。这证实了托卡马克中存在αTAE的全域捕获条件。在现行托卡马克中发现了多支αTAE。此外,还考察了在中性束注入实验过程中αTAE随时间的变化特性。展开更多
