Cost scaling analysis of large warm-bore superconducting quadrupoles

Abstract

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.
