Description
This poster presents simulation studies aimed at optimizing the design of the graphite target and capture system for the Muon Collider demonstrator, potentially at Fermilab. Using the G4Beamline simulation framework, we model proton interactions with a graphite target to analyze charged pion production and capture along the target axis, categorizing production mechanisms (primary, secondary, tertiary) and investigating spatial distributions to understand where pions are generated and how they can be efficiently collected. A key focus is on evaluating the impact of target geometry on pion yield and capture efficiency. In parallel, the study explores optimization of the magnetic capture system with a realistic tapered solenoid configuration following an initial capture solenoid, aiming to improve overall collection and transport of pions toward the downstream decay channel. These simulation results will provide a detailed foundation for refining both target and capture system designs to maximize pion production and muon yield for demonstrator tests, supporting the development of an effective, efficient target system for future muon source applications.
