A C type dipole with imbedded windings to improve the field distribution

Abstract

A method is described in this paper, which introduces some slots in the C type dipole pole and some conductors can be put inside these slots. These conductors can control the flow of the magnetic flux by adjusting its trim current, thus that can improve the magnetic field distribution at the median plane of this dipole. The effect of the trim current for low field was investigated using OPERA-2D and 3D, some results will be present in this paper. Furthermore, the fabricating technology of this C type dipole and some magnetic field measurement results will be discussed in this paper as well.

Summary of the Electroweak and Beyond the Standard Model Working Group

“…The sensitivity of the LHC searches are affected by the precision to which the proton parton distribution functions (PDFs) are known [59]. Uncertainties on the PDFs lead directly to uncertainties on both SM processes such as W , Z, t and H production and BSM processes such as hH + and aH + production in the MSSM.…”
