| 摘 要： | 利用一个小的环向涡旋脉冲电场（４．４Ｖ／ｍ，０．４５ｍｓ）成功地将ＨＴ－６Ｍ托卡马克等离子体电流从第一平顶（５５ｋＡ）提升到６０ｋＡ的第二平顶。其电流上升率大于１２ＭＡ／ｓ，电流上升时间远小于经典趋肤时间，实验中观察到了标志等离子体约束改善的明显物理现象。等离子体电流提升后，粒子约束时间提高了２．１倍，能量约束时间提高了１．６倍。

| Abstract: | Using a small pulse of toroidal vortex eletric field (4.4V/m, 0.45ms), plasma current is successfully ramped up from the plateau (55kA) to the second plateau (60kA) with a ramp rate dIp/dt>12MA/s on a time scale much fast than the classical skin time in the HT-6M Tokamak. The phenomena of improved confinement is observed in the present experiment. Particle confinement time is enhanced 2.1 times and energy confinement time, meanwhile, is enhanced 1.6 tines after ramping current up. |
