Abstract
This article describes the design and development of a translating-coil magnetometer for the room-temperature magnetic measurements of the superferric, high-order corrector magnets for the high-luminosity upgrade of the Large Hadron Collider at CERN (HL-LHC). The measurement system consists of a set of induction coils, tangentially positioned on a measurement head. The translation of the measurement head yields an induced voltage proportional to the longitudinal field profiles of the magnets. In this way, it is possible to locate the longitudinal center and calculate the magnetic length. The measurements provide feedback to the assembly and fabrication processes. The metrological characterization of the induction-coil configurations is presented, and the measurement results are discussed in view of the target requirements of the HL-LHC project.
