摘　　要：介绍了由锂回路、直线等离子体装置及液态锂净化系统等组成的液态锂综合实验回路平台。研究了液态锂与高密度等离子体相互作用、液态锂与结构材料相容性、液态锂净化和液态锂回路热工水力学参数测量等问题。实验结果表明,流动液态锂的蒸发速率与放电电流、氩气流量及磁场强度呈正相关关系。由流动液态锂产生的锂蒸气在轴向分布不具规律性,在径向分布呈高斯分布。流动液态锂的蒸发速率随着实验时间的增长逐渐升高,并趋于稳定。磁场抑制了液态锂的流动性。在磁场和等离子体长时间的作用下,流动液态锂表面生成一层很薄的氧化锂。Liquid lithium comprehensive experimental platform is introduced. The experimental platform is mainly consisted of lithium loop, linear plasma device, purification system and corrosion system. It is used to study the interactions of liquid lithium and plasmas, the compatibility of liquid lithium and structural material, purification of liquid lithium and measurement of the thermal-hydraulics parameters in liquid lithium loop and other key problems of science and technology. The experimental results show that lithium evaporation rate has a positive relationship with discharge current, argon flow rate and magnetic field strength, respectively. The axial distribution of lithium vapor produced by flowing liquid lithium has no regularity, but the radial distribution of lithium vapor is closed to Gauss Distribution. The flowing liquid lithium rate first increases with experimental time, and then tends to be stable. The mobility of liquid lithium is suppressed by magnetic field. A Lithium oxide film is produced under the long-term action of magnetic field and plasma.
