Abstract

A new gas-driven liquid metal (Sn) flow device named Gas-driven Liquid-metal Flow test device (GaLF) was established. The device is a pilot device for a linear plasma device that irradiates flowing liquid metal (LM) free-surface. The flow rate of Sn controlled by the inlet gas rate was evaluated by comparison with the weight change of the downstream Sn tank. A new method to achieve better wettability against liquid Sn by forming an intermetallic layer was suggested and tested in GaLF. The treated stainless steel showed better wettability enough to achieve a good free surface flow for plasma-surface interaction studies.

加热液态 Sn 流动系统的开发以及金属间层改善润湿性的初步结果

一种新型气体驱动液态金属（Sn）流动装置被命名为气体驱动液态金属流动试验装置（GaLF）。该装置是线性等离子体装置的试验装置，用于辐照流动的液态金属（LM）自由表面。通过比较下游锡槽的重量变化，评估了由入口气体速率控制的锡流量。在 GaLF 中提出并测试了一种通过形成金属间层实现更好的液态锡润湿性的新方法。经过处理的不锈钢显示出更好的润湿性，足以实现良好的自由表面流动，用于等离子体-表面相互作用研究。
