在实验先进超导托卡马克（EAST）上首次成功地实现了等离子体。实验研究了辉光放电（GDC）法渗硼。GDC硼化处理明显改善了等离子体性能。获得了操作区域的扩展和等离子体性能的改善。用软X射线信号、电子回旋发射信号和硼化后的线平均电子密度观测了锯齿状放电。GDC硼化处理后，Qa降低，运行稳定。由于硼化降低了杂质含量和降低了平均回路电压，等离子体电流上升速率也得到了改善。请注意：已经为这篇文章发布了一个撤回。
The first plasma has been achieved successfully in the Experimental Advanced Superconducting Tokamak (EAST). Boronization by the glow discharge (GDC) method was studied in experiments. The plasma performance was obviously improved by GDC boronization. Extension of the operational region and improvement in the plasma performance were obtained. Sawtooth discharges were observed by means of soft x-ray signals, electron cyclotron emission signals and line averaged electron density after boronization. Lower qa and more stable operation were also achieved following GDC boronization. The plasma current ramp-up rate was also improved as a result of decreased impurity content and low averaged loop voltage due to boronization.
