Design and cost studies were performed for mid-size (1-5 MWh), cold supported SMES systems using alternative configurations. The configurations studied included solenoid magnets, which required onsite assembly of the magnet system, and toroid and racetrack configurations which consisted of factory assembled modules.For each configuration, design concepts and cost information were developed for the major features of the magnet system including the conductor, electrical insulation, and structure, as well as all other systems in the plant. These studies showed that for 1 MWh-class systems, the costs of solenoid and toroid magnet configurations are comparable and that the specific configuration to be used for a given application should be based upon customer requirements such as limiting stray fields or minimizing risks in development or construction.
This paper presents an approach to estimating the cost of large warm-bore superconducting quadrupoles that are frequently used in magnetic imaging system in accelerators. Quadrupole magnet radial apertures greater than about 10 cm and gradients exceeding 10 T/m are considered. A relationship is established so that the cost estimate may be scaled with the gradient, aperture, and length of the magnet.Zndex Terms-Accelerator lens magnets, quadrupoles, superconducting magnets, superconductivity.
A51 0 MeV electron-positron collider has been proposed at UCLA to study particle beam physics and Phi-Meson physics, at luminosities larger than 1032 cm-2 s-1. The collider consists of a single compact superconducting storage ring (SMC), with bending field of 4 T and a current larger than 1 A. We discuss the main characteristics of this system and its major technical components: superconducting dipoles, RF, vacuum, injection.
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.
