【摘要】：磁压缩系统为俄罗斯实验物理研究院提出的核聚变方案。磁压缩系统腔室中杂质粒子可能来源于热脱附、等离子体刮削器壁等途径。利用ANSYS工具模拟5 MA脉冲电流流过腔室,并给出电极温度的二维分布图,结合研究小尺寸铜样品上杂质的解吸附来分析磁压缩系统腔室中热脱附过程产生的杂质粒子。通过测量3keV的Ar~+离子入射到Cu(110),Cu(111)样品表面的飞行时间谱,分析样品表面吸附的杂质种类,以及样品表面杂质含量随温度的变化关系。研究表明杂质粒子含量跟电极温度有关联性,且跟电极材料表面结构相关。
[Abstract]:The magnetic compression system is a nuclear fusion scheme proposed by the Russian Institute of Experimental Physics. The impurity particles in the chamber of magnetic compression system may come from thermal desorption and plasma scraper wall. The 5 MA pulsed current flow through the chamber was simulated by ANSYS, and the two-dimensional distribution of electrode temperature was given. The impurity particles produced during the thermal desorption process in the chamber of magnetic compression system were analyzed by studying the desorption of impurities on small copper samples. By measuring the time-of-flight spectra of 3keV Ar~ ions incident to the surface of Cu (110), Cu (111) samples, the kinds of impurities adsorbed on the surface of the samples and the relationship between the surface impurity content and the temperature were analyzed. The results show that impurity particle content is related to electrode temperature and surface structure of electrode material.
