A muon spectrometer for condensed matter and molecular studies.

The RIKEN - RAL Muon Facility is an international collaboration with the RIKEN institute in Japan to promote muon science. It supports a wide range of  investigations including muon catalysed fusion studies and fundamental muon investigations.

The muon instrument Argus (Advanced Riken General-purpose mUsr Spectrometer) is housed in Port 2 of the RIKEN-RAL Muon Facility. It can be used for a wide variety of studies in the areas of magnetism, superconductivity, charge transport, molecular and polymeric materials and semiconductors.  It has:

  • 192 detector elements
  • Data rates ~70 MeV/hr (double pulse)
  • temperature range 30mK - 800K
  • longitudinal field range 0 G - 4000 G LF
  • transverse field range 0 G - 150 G TF
  • Pressure experiments: He - gas pressure and hydrostatic pressure, up to 0.7 GPa, to 1.5K (gas) or to 30mK (hydrostatic)
