Description
Muon sources are critical in advancing both fundamental physics research and various applied sciences. High-Repetition-Rate (HRR) muon beams, in particular, are optimal for numerous precision experiments in fundamental physics. To assess the accuracy of the simulation model for the HRR muon beam produced at the SHINE facility (The Shanghai High repetition rate XFEL and Extreme light facility), a comparative analysis was conducted using simulated data for the 1.6 GeV,10 Hz electron beam at the SXFEL facility (The Shanghai Soft X-ray Free-Electron Laser User Facility) with a beam dump. The simulation model facilitated an examination of the intensity, trajectory, and temporal distribution of the muons, as well as background particles. Leveraging these particle characteristics, we have devised and preliminarily confirmed the viability of experimental approaches for muon detection. In the case of positive muons, a stopping target captures the particles, and their intensity is quantified by recording the temporal distribution of resultant positrons using a plastic scintillator detector. This is predicated on the distinctive rest lifetime characteristic of the positive muon. Conversely, negative muons are detectable through capture by a metallic target, whereupon the emission of muonic X-rays is observed via LaBr3 crystal detectors. The intensity of the negative muons can be determined from the peak’s amplitude.
