对 QUEST 上非感应长持续等离子体中的全局粒子平衡进行了研究。大约70%的燃料氢气(H)被保留在壁中，并且在排放后几乎被耗尽。总体回收率（Rg）定义为排出的氢气通量与注入的氢气通量之比，被发现在放电过程中逐渐增加，随后迅速上升。为了研究 Rg 的生长，使用一个模型分析了暴露于 QUEST 等离子体的样品中注入氘后的热解吸光谱，该模型包括反射、扩散、溶解、复合、捕获和再沉积层中的等离子体诱导解吸。该模型重建了 Rg 在长时间等离子体期间的生长，并表明溶液在生长中起主导作用。
Global particle balance in non-inductive long-duration plasma on QUEST has been investigated. Approximately 70% of the fuel hydrogen (H) was retained in the wall and then was almost exhausted just after the discharge. The global recycling ratio (Rg), defined as the ratio of the evacuated H2flux to that injected, was found to gradually increase during discharges and subsequently rose rapidly. To study the growth ofRg, the thermal desorption spectra after deuterium implantation in a specimen exposed to QUEST plasma was analyzed with a model which includes reflection, diffusion, solution, recombination, trapping, and plasma-induced desorption in the re-deposition layer. The model reconstructs the growth ofRgduring a long-duration plasma and indicates solution plays a dominant role in the growth.
