Research on optimum design and reapplicability of superconducting level sensor for liquid hydrogen

建立了再现实验结果的数值计算程序，并对不同护套材料的MgB2丝组成的液氢超导液位传感器进行了优化设计。用具有SUS/Fe护套的MgB_2丝制作了具有常规结构的超导液位传感器，并对其在液氦和液氢中的工作进行了测试和评价。在此基础上，提出了一种新型的液氢超导液位传感器结构，并通过数值模拟验证了该结构的可行性。

The numerical code to reproduce the experimental results carried out previously was established, and the superconducting level sensors for liquid hydrogen composed of MgB_2 wires with different sheath materials were designed optimally. A superconducting level sensor with a conventional structure was also fabricated using an MgB_2 wire with SUS/Fe sheath, and its operations were tested and evaluated in both liquid helium and liquid hydrogen. Furthermore, a new structure of superconducting level sensor for liquid hydrogen was proposed, and its operation was validated by numerical simulation.
