Fine Tuning of the Inner Dipole Design of MCBXF Magnets

Two types of nested orbit correctors are necessary for LHC upgrade, the so-called MCBXFA and MCBXFB. They share the same cross section, but feature different lengths, 2.5 and 1.5 m, respectively. The power tests performed on two MCBXFB prototypes showed excellent performance when individually powere...

description Two types of nested orbit correctors are necessary for LHC upgrade, the so-called MCBXFA and MCBXFB. They share the same cross section, but feature different lengths, 2.5 and 1.5 m, respectively. The power tests performed on two MCBXFB prototypes showed excellent performance when individually powered, but training to reach the nominal torque in combined operation was very long. Moreover, memory was lost after torque direction reversal. A detailed analysis of the power test results concluded that the origin of the problem was insufficient support for the torque at the inner dipole coil ends. A fine tuning of the inner dipole design is proposed to improve the performance of both types of magnets. This paper describes the analytical and numerical models developed to analyze the problem and their results.
