The RIKEN-RAL muon facility

Specification of the RIKEN-RAL Muon Facility

• Decay (positive and negative) muon beam and surface muon beam are produced.
• Muon momentum range : 20 – 120 MeV/c
• Muon beam intensity (200μA proton beam and 10mm thick production target )
  • Decay positive muon: 4 x 10⁵ /sec （60 MeV/c）
  • Decay negative muon: 7 x 10⁴ /sec （60 MeV/c）
  • Surface muon : 1.5 x 10⁶ /sec （27 MeV/c）
• Double pulsed muon beam is separated into two single muon pulses.
• Two different muon experiments can be performed independently.
• Promoting four unique muon experiments at four experiment ports.
