Design and Experimental Evaluation of Muon Trigger Detectors for Industrial Applications

Strategic Insights

— 2 min read

Researchers at the Institute of Fluid Dynamics have successfully designed and experimentally evaluated muon trigger detectors tailored for industrial-scale applications. The study utilized an organic scintillator plate measuring 250 x 250 x 10 mm in size, configured with varying numbers of silicon photomultiplier (SiPM) devices, each with a detection area of 4 x 4 mm. The research was funded by the Helmholtz Association and the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV). The team's work aimed to optimize dark count suppression and muon event discrimination, with a focus on enhancing the detected scintillation photon yield.

Key Takeaways:

  • The researchers designed four different detector configurations, each optimized for individual performance.
  • Spatially resolved muon detection efficiency was assessed using a muon coincidence detector with an active area of 50 x 50 mm.
  • The assembly procedures for the different detector configurations were discussed in the study.
  • A trigger detector configuration incorporating a single SiPM device coupled with a wavelength-shifting fiber clamp was identified as providing the most efficient collection for scintillation photon yield.
  • This configuration is cost-effective, modular, and easy to mass-produce, making it suitable for large-scale muon trigger detectors in industrial applications.
  • The research was conducted using an organic scintillator plate, which was configured with varying numbers of SiPM devices.
  • Various reflective materials, such as reflective paint, aluminum foil, and high-gloss paper, were applied to enhance the detected scintillation photon yield.
  • The study focused on optimizing dark count suppression and muon event discrimination.
  • The research concluded that the designed detector configuration is well-suited for industrial applications due to its cost-effectiveness, modularity, and ease of mass production.

Statistics:

  • The muon trigger detectors underwent experimental evaluation using an organic scintillator plate with dimensions 250 x 250 x 10 mm.
