ISIS Neutron and Muon Source is based at the STFC Rutherford Appleton Laboratory in Oxfordshire and is a world-leading centre for research in the physical and life sciences. It is owned and operated by the Science and Technology Facilities Council.

ISIS Neutron and Muon Source produces beams of neutrons and muons that allow scientists to study materials at the atomic level using a suite of instruments, often described as ‘super-microscopes’. It supports a national and international community of more than 2​000 scientists who use neutrons and muons for research in physics, chemistry, materials science, geology, engineering, and biology.

ISIS neutron and muon instruments are free to use for researchers provided the results from experiments are published in the public domain. Fully confidential use of the instruments is also available for industrial and commercial customers. ​
