Abstract:
The concept is proposed of a gaseous phase sensor for long nitrogen cryostat using high-temperature superconducting wires. The principle of operation of the sensor is based on jump-wise transition to normal state of a superconducting bifilar current carrying wire when a part of the bifilar is under nitrogen vapor. Experiments have been carried out on the sensor physics simulator that confirm its working ability and its feasibility to be scaled up to the long cryostat size.
Keywords:high-temperature superconducting wire, gaseous phase sensor, long cryostat, bifilar.
