Description
To establish hydrogen worldwide storage and marine transportation, it is important to develop liquid hydrogen tanks/carriers like liquefied natural gas tanks/carriers as well as a long level sensor such as a superconducting magnesium diboride (MgB2) level sensor. In the case of lengthening the MgB2 level sensor, a whole MgB2 wire needs uniform superconducting characteristics. Long MgB2 wires 1.7 m long and 0.32 mm in diameter, which were fabricated by in-situ method and reinforced by a CuNi (7:3) sheath, were taken as an object of study. To suppress the critical temperature of the wires, impurities (10% SiC) were added to the MgB2 core. A characteristic Difference among all the individuals of the same 20 mm-long MgB2 short wires were discussed.
