The beamline design philosophies and simulation results of the decay muon on Experimental Muon Source (EMuS) are reported in this paper. The trunk of the beamline is mainly composed of solenoids to keep a large acceptance, and has been optimized for 45, 150 and 450 MeV/c decay muons respectively according to the π spectra optimization results from the target station. Three spectrometers are planed for decay muons, corresponding to μSR application, muon imaging and muonic application respectively. Decay muons from 45 to 150 MeV/c with polarization above 75% are designed for μSR applications, and high momentum muons up to 450 MeV/c are designed for muon imaging. Negative decay muons from 45 to 150 MeV/c are designed for muonic applications. The momentum of the decay muons is tuneable between 45 and 450 MeV/c.
