Vestale loop: a robust, versatile, reliable and remote controlled bench for environmental magnetic sensing at hectometric scale

Abstract

Proofs of well-functionning of an original hectometric magnetic bench, located in the South of France, at the Low Noise Underground Laboratory (LSBB for french acronym), Rustrel, are presented. Two different kinds of electrical measurements are justified and exposed. They are based on the monitoring of electrical quantities as characteristics and spontaneous induced bias, over the time and during periods of several weeks. A very first correlation with meteorological data is also presented. The technical as the scientific perspectives are exposed at the end.
