High-temperature superconducting level meter for liquid argon detectors Bueno Villar, Antonio Melgarejo-Fernández, Antonio Jesús Navarro, J. L. Navas Concha, Sergio Ruiz, A. G. Cryogenic detectors Superconductive detectors Control and monitor systems on-line Capacitive devices are customarily used as probes to measure the level of noble liquids in detectors operated for neutrino studies and dark matter searches. In this work we describe the use of a high-temperature superconducting material as an alternative to control the level of a cryogenic noble liquid. Lab measurements indicate that the superconductor shows a linear behaviour, a high degree of stability and offers a very accurate determination of the liquid volume. This device is therefore a competitive instrument and shows several advantages over conventional level meters. 2013-11-07T13:53:07Z 2013-11-07T13:53:07Z 2008 info:eu-repo/semantics/article Bueno, A.; et al.
