| 中文摘要 | reductions in h content and particle recycling are important for the improvement of ion cyclotron range of frequency (icrf) minority heating efficiency and the enhancement of plasma performance of the east superconducting tokamak. during recent years several techniques of surface conditioning such as baking, glow discharge cleaning/icrf discharge cleaning, surface coatings, such as boronization, siliconization and lithium coating, have all been attempted in order to reduce the h/(h+d) ratio and particle recycling in east. even though boronization and siliconization were both reasonably effective methods to improve plasma performance, lithium coatings were observed to reduce the h content and particle recycling to levels low enough to allow the attainment of enhanced plasma parameters and operating modes on east. for example, by accomplishing lithium coating using either vacuum evaporation or the real-time injection of fine lithium powder, the h/(h+d) ratio could be routinely decreased to about 5%, which significantly improved icrf minority heating efficiency during the autumn campaign of 2010. due to the reduced h/(h+d) ratio and lower particle recycling, and a reduced h-mode power threshold, improved plasma confinement and the first east h-mode plasma were obtained. furthermore, with increasing accumulation of deposited lithium, several new milestones of east performance, such as a 6.4 s-long h-mode, a 100 s-long plasma duration and a 1ma plasma current, were achieved in the 2010 autumn campaign. |
