Numerical Analysis of Hybrid REBCO-Cu Coatings for the Future Circular Collider Beam Screen

Simulation files and data of the beam screen (BS) of the Hybrid Future Circular Collider (FCC) with a hybrid coating composed of alternating segments of REBCO high temperature superconductor (HTS) and copper. 00. All Simulations: All simulation files with no solutions. 01. ParametricStudy: Several coating geometries are evaluated in terms of the field quality within the reference radius of the FCC BS. The coatings are defined by the number of segments (n) and the ratio of HTS in the flat portions of the BS (p). The simulation files are generated via COMSOL LiveLink for MATLAB, with the MATLAB script ParSweepAutoSims. 02. HspmSims: The experimental setup of a Hall Scan Probe Microscopy measurement of trapped field is replicated with hybrid coatings of different p and n. 03. AcDemagnetization: The effect of a perpendicular AC field superimposed to a DC field to the current flowing in a HTS tape is simulated. 04. ProposedGeometry: A coating geometry is proposed based on the results of the parametric study. 05. MisalignedMultipole: The proposed geometry submitted to other magnetic field configurations as tu study the impact on field harmonics due to a quadrupole field, hysteresis, creep and misalignments. Each study requires different magnetic field inputs, which should be selected appropriately in the definitions tab. The MATLAB script FieldHarmCalc is used to calculate the field harmonics. 06. ThermoMechanical: The thermomechanical response of the coated beam screen is investigated. Dipole-induced heat as well as resistive wall heating and synchrotron radiation are considered. 07. DipoleQuench: The consequences of a quench of the main dipole magnets is studied. Temperature dependent material properties are taken into account. 08. TransverseCurrent: The correlation between transverse current flow and length in electronically coupled HTS segments is analysed in a simplified geometry. 09. RebcoProperties: The files containing the material properties used in the simulations. Data from S. Wimbush, N. Strickland, and A.
