Description
Abstract: The development of high-field magnets is on-going in the framework of the LHC luminosity upgrade. The resulting peak field, in the range of 12 T, requires the use Nb3Sn as superconductor. Due to the high stored energy density (compact winding for cost reduction) and the low stabilizer fraction (to achieve the desired margins), quench protection becomes a challenging problem. Given the little margin, a detailed understanding of the thermodynamic processes during a quench is hence crucial for the design of the essential protective elements. Here we describe a modelling approach where the complex problem is split in simpler building blocks and joined into a consistent solution. The model is compared to data from supporting experiments and magnet model tests. A parametric study is then presented in support to the design and construction of the magnet prototypes.
