Abstract

This paper presents a conceptual design for the first tentative surface muon source based on the proton beam provided by China Spallation Neutron Source. We have calculated the optimal parameters of solid muon target, in which the method of Monte Carlo simulation is used to obtain the optimal muon beam parameters, such as beam fluence rate, momentum spread and phase space distribution. A simple muon transport beamline system was also designed, which could transport the muons emitted from the muon target into the experimental area, where positrons from muon decay in a test sample are detected by a spectrometer. The beam optics of this new beam line is also described.
- spallation neutron source,
- surface muon,
- muon production target,
- charged particle transport
