液态金属壁厚的空间和时间分辨电阻测量

Space- and Time-resolved Resistive Measurement of Liquid Metal Wall Thickness

S. M. H. Mirhoseini, F. A. Volpe

摘要:

在内部涂覆有液态金属的聚变反应堆中,重要的是诊断容器中各个位置处的液体厚度,作为时间的函数,并且可能响应以抵消不期望的膨胀或耗尽。浸入液态金属中的电极之间的电导率可以用作局部厚度的简单代表。这里示出了电极矩阵,以在不存在等离子体的情况下提供液态金属厚度的空间分辨测量。首先对mxn电极建立了理论,然后对3x1电极进行了实验验证。实验是用Galinstan进行的,但很容易扩展到锂或其他液体金属。

英文摘要:

In a fusion reactor internally coated with liquid metal, it will be important to diagnose the thickness of the liquid at various locations in the vessel, as a function of time, and possibly respond to counteract undesired bulging or depletion. The electrical conductance between electrodes immersed in the liquid metal can be used as a simple proxy for the local thickness. Here a matrix of electrodes is shown to provide spatially resolved measurements of liquid metal thickness in the absence of plasma. First a theory is developed for mxn electrodes, and then it is experimentally demonstrated for 3x1 electrodes. The experiments were carried out with Galinstan, but are easily extended to Lithium or other liquid metals.
