Design of a 4 tesla superconducting dipole magnet for CERN experimental North-Area

The object of this dissertation is the design of a 4 T superconducting dipole magnet. This magnet will be used for testing of future detectors instrumentation and it has been envisioned to replace or complement the outdated systems available at the North Experimental Area at CERN. The magnetic design has been performed via Finite Element Analysis. A FE model is prepared in ANSYS Maxwell 3D for modeling the magnetic field of such large magnets, this model was validated using the geometry and operating parameters of an existing magnet at CERN: the H8 Morpurgo dipole. The magnetic design consists in the optimization of the coil geometry for matching the requirements in terms of central magnetic field, peak field in the conductor and stray field. Two different geometries are investigated for the magnet system: split saddle shape and flared-end geometry. The most favorable one is chosen to proceed with the windings cable design. To conclude, a support structure is designed to handle Lorentz forces acting of the magnet cold mass. The mechanical simulation is performed via Finite Element Analysis using ANSYS Static Structural.
