“…It has several independent modes: a) surface muon mode for µSR physics; b) decay muon mode, for higher energy µSR physics and muon imaging; c) an optional neutrino mode for low energy neutrino cross section measurements [3]. Downstream, pion and muon beamlines are being designed in order to allow the pions to decay into muons, and transport muons to detectors [4]. The second muon beam scheme is a conventional µSR experiment called "baby", where the surface muon capture is done by a quadrupole sideways at 90 • from the protontarget interaction.…”

“…Decay muons at detector are related to the pion capture and transportation from the target station. Pion momentum selection and charge separation are applied downstream of the capture and matching solenoids along the beamline [4]. For muon science and this study, π + s with 128, 225 and 450 MeV /c within ±10% are required in order to produce µ + s with central momentum of 60, 120 and 450 MeV /c respectively [7].…”

In this article, the latest studies of the Experimental Muon Source (EMuS) target systems for muon production and capture are briefly presented. The EMuS is foreseen to be located at the China Spallation Neutron Source (CSNS) in Dongguan. It uses the proton driver of the neutron source and comprises of different target stations and beam lines for muons. EMuS will be a world class muon source especially competitive for muon Spin Resonance (µSR) experiments.

“…The beam energy was simulated according to the Experimental Muon Source (EMuS) under construction in the Chinese Spallation Neutron Source (CSNS) in Dongguan, China. The momentum of a surface muon beam and a high-energy decay muon beam ranges from approximately 30 to 600 MeV c −1 [19]. Therefore, except for the momentum (450 MeV c −1 ≈460 MeV in kinetic energy) currently under consideration for imaging, the distribution of 50 MeV and 200 MeV decay muons was also simulated.…”

The distribution of muon beams and secondary positrons can be vital reference data for the application of the accelerator muon transmission imaging technique. In this study, the distribution of muon beams and secondary positrons in biological tissue, semiconductors, and metals was simulated using Geant4. The muon beam showed an extremely concentrated decay area, which presented quite high depth resolution (FWHM ranging from 1.68 cm to 11.83 cm) and great penetrability (mean depth ranging from 18.03 cm to 198.97 cm) in media. Based on the simulation data, an empirical equation was designed for the quick calculation of muon beams with different energies in various materials. Additionally, the secondary positrons distribution of a 200 MeV muon beam centered on its decay position and covered an 8.50 cm radius area in Fe. The number of positrons was much higher than that of primary muons, especially in high-density materials. As a consequence of these two aspects, the combined signal processing of muons and secondary positrons provides the potential to improve muon imaging.
