Aerial view of ISISISIS 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, one of the councils that forms UK Research and Innovation (UKRI).  

Our mission is for neutrons and muons to advance knowledge and improve lives.
Our vision is that ISIS will lead the way in the innovative development and exploitation of neutron and muon sources, science, instrumentation and technology.

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’, each of which is individually optimised for the study of different types of matter. Neutron and muon experiments are non-destructive and provide results that cannot be achieved by other techniques. We​ support 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. For some recent examples, see our Science Highlights​.

We work with both academia and industry​ to deliver scientific, socio-economic and environmental impact, addressing global challenges and answering fundamental questions.​ The ISIS Strategy 2030 outlines the priorities and activities needed to ensure the UK continues to have access to a world-leading centre of excellence in neutron and muon science to 2030 and beyond.​

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.  ​

A typical year at ISIS involves: ​

1200 experiments by 3000 users from 30 countries generating 600 publications


The ISIS Leadership Team (ILT) is the senior l​eadership board within ISIS, responsible for the development and delivery of the strategy and the oversight of all project and operations. ISIS is also ​​​supported by various oversight and advisory boards.
