“…Three orbit correctors placed close to the triplet quadrupoles provide up to 2.1 T dipolar field both in horizontal and vertical direction, giving rise to a torque of 140 kN•m/m. [3,9,25]. Two versions are needed: a 1.5-m-long magnet to be installed in each cold mass of the Q2a/b magnets, and a 2.5-m-long magnet in the corrector package cold mass.…”

About one hundred magnets of six different types shall be installed in the High Luminosity LHC (HL-LHC) in the years 2026-2028 at CERN. The magnets design, construction and test are based on CERN collaborations with institutes and industrial partners in USA, Spain, Italy, Japan and China. Three types of correctors are based on Nb-Ti technology and feature conductor peak fields in the 2 to 4 T range: for all of them the protoype phase has been successfully completed. The production is well advanced for the superferric correctors, and is starting for the canted cosine theta correctors and for the nested correctors. The separation and recombination Nb-Ti dipoles D1 and D2, with a 4.5-6 T bore field range, are both in the prototype phase after the completion of the short model program. The most challenging magnet, the Nb3Sn quadrupole with conductor peak field above 11 T, is in the prototype phase at CERN and halfway through the production phase in the USA. In this paper we will give, for each type of magnet, an overview of the main achievements obtained so far and we will outline the technical points still needing validation from the prototype program.

“…KEK and INFN-Genova provide the Nb-Ti based separation and recombination dipoles [7,8], and the three types of correctors are manufactured under the helm of CIEMAT, IHEP and INFN-LASA [9,10,11]. Each magnet type has to be produced in mini-series (6 to 50 magnets): this poses special challenges to the timeline of corrective actions.…”

This paper 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.
