Description

This study uses FLUKA simulations to investigate pion production from proton interactions with a graphite target for muon collider applications. A 40 cm target is struck with 0.8 GeV and 8 GeV/c proton beams, and pion yields are evaluated in terms of angular and energy distributions. The dependence of pion yield on target length is also examined, showing saturation near one interaction length for the 0.8 GeV beam, and saturation near two interaction lengths for the 8 GeV/c beam due to secondary interactions. In addition to total production, a subset of “acceptable” pions is defined based on capture constraints (kinetic energy <400 MeV, forward-going, and escaping the target). The results show that while the 8 GeV/c beam produces higher overall yields, the 0.8 GeV beam provides a larger fraction of pions within the desired constraints. Charge asymmetry is also observed in pion production, with implications for muon beam balance and collider luminosity.
