Description
Summary:The Large Hadron Collider (LHC) upgrade, namely, High Luminosity LHC (HL-LHC) is planned for the next decade. A set of twin aperture beam orbit correctors positioned on the approaches to the ATLAS & CMS experiments will be developed. Two Chinese Academy of Sciences institutes, i.e., IHEP (Institute of High Energy Physics) and IMP (Institute of Modern Physics), and one company in China will work on the magnet R&D and series production. IMP is in charge of the performance test both at ambient and cryogenic temperatures, and the first China-built model (MCBRDP2) has been tested recently. In this paper, the test setup for magnetic measurements, the room temperature bore, and the rotating coil probe being system used at IMP are presented. The quench record and the measurement results, such as integral field, multipoles, cross-talk, are given and discussed.
