The following institutions offer muon beams suitable for &micro;SR experiments: 

===[[TRIUMF]]=== 
The ''Tri''-''U''niversity ''M''eson ''F''acility (so named for the original three founding Universities) in Vancouver, British Columbia, Canada, now operates as a national laboratory under the collective auspices of a growing number of Canadian Universities, with a budget from the National Research Council (NRC) of Canada.  TRIUMF's facilities centre around a sector-focused, isochronous H<SUP>-</SUP> accelerator (the world's biggest cyclotron) and a suite of radioactive beam accelerators at ISAC (Isotope Separator and ACcelerator) with several smaller cyclotrons providing isotopes for medical research.

===[[PSI]]=== 
The ''P''aul ''S''cherrer ''I''nstitut in Villigen, Switzerland, has the world's highest intensity muon beams.  Like TRIUMF, it uses an isochronous cyclotron to achieve a continuous beam and so &micro;SR experiments usually involve start-stop timing on individual muons, giving high time resolution but restricting rates to about 10<SUP>5</SUP> muons/second.  PSI also hosts a reactor, a spallation neutron source and a synchrotron light source.  

===[[ISIS]]=== 
The ISIS facility of the Rutherford Appleton Laboratory near Oxford, U.K., is primarily a spallation neutron source using the pulsed beam from a proton synchrotron, but it also boasts the world's highest intensity ''pulsed'' muon beams, at least until [[J-PARC]] begins operation.

===[[J-PARC]]=== 
The ''J''apan ''P''roton ''A''ccelerator ''R''esearch ''C''omplex in Tokai, Japan, begin producing muons in 2008.  It may be expected to develop into a world-leading laboratory for what is now loosely termed "Medium Energy" Particle Physics, with facilities for nuclear physics, life sciences and, of course, &micro;SR.  The beam will be pulsed (similar to ISIS).
