Description
This study investigates magnetic horn focusing as an alternative to superconducting solenoids for the Muon Collider Demonstrator. We explored a double horn structure as an R&D exercise for a possible muon-collider frontend, tailored to capture pions in the 100-400 MeV/c momentum range. An XGBoost-based optimization pipeline was applied to refine geometric and current parameters to maximize pion yield while maintaining acceptable emittance. To validate performance, we benchmarked the single horn structure against IMCC design baselines and compared the optimized double horn structure with the solenoid channel, using Geant4 and FLUKA simulations. The results provide a critical assessment of the trade-offs between the lower-cost magnetic horn approach and superconducting solenoids, offering a potential pathway for a more economically viable Muon Collider Demonstrator.
