| Research Abstract |
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.
