Abstract

Abstract:

The experiments about plasma heating and current drive with NB counter-injection on EAST are presented and the energy heat transport in the neutral-beam injection with high power is also analyzed with the TRANSP code developed by the Princeton Plasma Physics Laboratory. The experiments and simulations show that neutral beam injection can effectively increase background plasma temperature, lead to beam driven non-inductive current, enhance plasma rotation and effectively improve plasma confinement.

Key words: NB counter-injection, Non-inductive current driven, Confinement improvement, Plasma rotation, TRANSP code

摘要：

对EAST中性束反向注入过程中等离子体加热和电流驱动进行了实验研究，并采用了美国普林斯顿大学等离子体物理实验室开发的TRANSP 程序对高功率中性束注入过程中能量热输运进行了分析。结果表明，中性束注入可有效提高本底等离子体温度，产生束驱动非感应电流，提高等离子体旋转以及有效改善等离子体约束。
