Superconducting magnet design and analysis

This work focuses on the design, simulation, fabrication and testing of accelerator-grade superconducting magnets using advanced modeling tools, and proprietary winding and testing techniques available at Brookhaven National Laboratory. The magnetic field behavior of various magnets designed are explored along with other parameters that influence the performance of the  magnets and their suitability for high-energy physics applications.

In these designs we utilized two main software tools: Simulia OPERA and Rat-GUI. In OPERA, 3D models of dipole and quadrupole magnets were created and simulated. A series of parametric studies were performed by altering yoke material properties and current densities. The resulting magnetic field distributions were analyzed to evaluate field strength and uniformity under varying configurations.

Using Rat-GUI, the team constructed and simulated a canted cosine theta (CCT) quadrupole coils. This model underwent line and cylindrical harmonics analysis, focusing on the magnetic flux distribution, which is a key metric for magnet performance. The finalized coil geometry was exported, processed via MATLAB, and 3D-printed onto a cylindrical surface, producing a physical prototype of the magnet. Last, but not least, the magnets were tested using rotating coil magnetometers and the results were validated against the design.
