Abstract

An experimental muon source is planned for the China Spallation Neutron Source. A simplified beamline with a limited number of magnets is achieved using a FODO lattice for implementation in a future preliminary stage. The yield of the muon delivered to the experimental sample is slightly larger than 105 μ+/s within the FWHM beam spot (~ Ø30 mm) from a thick muon target. In addition, the beam polarization is 92% and the contamination that is mainly formed by positrons is approximately a fraction of 1%.
