Superconducting magnet coil system

Abstract

The invention relates to a superconducting magnet coil system comprising a first electrical mesh (M) and a second electrical mesh (M), which are interconnected in series with one another, wherein the first electrical mesh (M) comprises in a first path an HTS (high temperature superconductor) coil section (A) and, in series therewith, a first main coil section (A) and in a second path a quench protection element (Q), which bridges the series connection of HTS coil section (A) and first main coil section (A). The first main coil section (A) comprises a conductor comprising superconducting filaments in a matrix. The second electrical mesh (M) comprises a neighbouring main coil section (A) comprising a conductor comprising superconducting filaments in a matrix. The neighbouring main coil section (A) is that main coil section of an electrical mesh different from the first electrical mesh which, in a radial direction outwards, lies closest to the first main coil section (A) of the first electrical mesh. The magnet coil system is characterized in that, in the case of a quench, the conductors of the main coil sections (A, A, A) each generate a specific power input (LT/2π)*1/ρ, wherein the specific power input of the conductor of the first main coil section (A) of the first electrical mesh (M) is higher than the specific power input of the conductor of the neighbouring main coil section (A) of the second electrical mesh (M). Consequently, using HTS superconductor material, it is possible to provide a magnet coil system with which particularly high field strengths can be generated and/or which has a small structural size.
