ISMS and the World µSR Community

This wiki is presently maintained on a server at TRIUMF, but it is intended to serve anyone involved or interested in µSR worldwide. To reduce the chance of abuse or vandalism, we require registration in ISMS (the International Society for µSR Spectroscopy) for those who wish to contribute to this wiki (editing, adding or correcting information); anonymous visitors may read all they want but may not make changes. Membership in ISMS is free of charge and entails no responsibilities other than common sense and courtesy.

The following institutions offer muon beams suitable for µSR experiments:

TRIUMF

The Tri-University Meson Facility (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-focussed, isochronous H^- 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 Paul Scherrer Institut 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 µSR experiments usually involve start-stop timing on individual muons, giving high time resolution but restricting rates to about 10⁵ 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.
