Powering Tests Results of the First Batch of MCBXFB Magnets Produced in Industry

MCBXF magnets are orbit nested correctors for the HL-LHC project, an upgrade of the Large Hadron Collider (LHC). The magnet design consists of two nested dipoles, with an aperture of 150 mm. The magnets have been designed in two physical lengths, namely of 2.5 m (MCBXFA) and 1.5 m (MCBXFB), with the same cross section according to the necessities. Two prototypes and the first series magnet of the short version were manufactured at CIEMAT and assembled at CERN. The series production of the rest of the series magnets, 6 long (MCBXFA) and 11 short (MCBXFB) magnets, is being carried out at the premises of the company Elytt Energy. In this paper the powering test results of the first batch of MCBXFB magnets produced in the industry are presented, including both the results of training and magnetic measurements. An endurance test was made to check the reliability of the magnets after a large number of powering cycles and torque inversions.
