A Superconducting Liquid-Level Sensor for Slush Hydrogen Use
The fact that solid-liquid mixtures of hydrogen, commonly known as slush hydrogen, are being considered for use as rocket propellants has stimulated interest in the development of liquid-level sensors for systems of this type. Slush exists at the triple point temperature of hydrogen, and since this temperature is below the transition temperature of several superconducting compounds, it should be possible to construct a superconducting liquid-level sensor (point or continuous) for use in slush hydrogen.
