| Research Abstract |
First, observations on the damped oscillation of liquid hydrogen surface inside a small vessel as well as acquisition of the output signal of a superconducting MgB2level sensor under horizontal vibration were carried out. These experimental values were qualitatively in agreement with computed values based on simulation analysis. Second, data of liquid hydrogen level, temperature and pressure inside a large vessel during a truck transportation were measured synchronously with a large sloshing signal. These experimental values were also qualitatively in agreement with computed values. Accordingly, there is the prospect for developing a new method of 3D sloshing measurements inside a shipping liquid hydrogentank using superconducting level sensors.
