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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
