ISIS Neutron and Muon Source

The ISIS Neutron and Muon Source is a pulsed neutron and muon source, established 1984 at the Rutherford Appleton Laboratory of the Science and Technology Facilities Council, on the Harwell Science and Innovation Campus in Oxfordshire, United Kingdom. It uses the techniques of muon spectroscopy and neutron scattering to probe the structure and dynamics of condensed matter on a microscopic scale ranging from the subatomic to the macromolecular.

Hundreds of experiments are performed every year at the facility by researchers from around the world, in diverse science areas such as physics, chemistry, materials engineering, earth sciences, biology and archaeology.

The source was approved in 1977 for the RAL site on the Harwell campus and recycled components from earlier UK science programmes including the accelerator hall which had previously been occupied by the Nimrod accelerator. The first beam was produced in 1984, and the facility was formally opened by the then Prime Minister Margaret Thatcher in October 1985.

The name ISIS is not an acronym: it refers to the Ancient Egyptian goddess and the local name for the River Thames. The name was selected for the official opening of the facility in 1985, prior to this it was known as the SNS, or Spallation Neutron Source. The name was considered appropriate as Isis was a goddess who could restore life to the dead, and ISIS made use of equipment previously constructed for the Nimrod and NINA accelerators.


There are three options for getting online at DENIM XI:

This is the easiest option as you may already have it set up on your device.

GovWifi https://www.wifi.service.gov.uk/connect-to-govwifi/
This requires sending an SMS to get online.

STFC-Guest Visitor WiFi https://visitorwifi.stfc.ac.uk/

This is aimed at visitors who cannot already use another WiFi network e.g. eduroam or GovWifi. Use one of the DENIM XI organising committee as the sponsor's name.

DENIM History: list of past DENIMS

First held in 2012, the Design and Engineering of Neutron Instruments Meeting (DENIM) has been hosted by seven different neutron scattering facilities worldwide. At DENIM each year, the neutron scattering community reaps the benefits of building relationship and sharing expertise amongst themselves and their sponsorship partners. Several pictures from past DENIM events can be found below. Also please note that upon activation of the ISNIE website, power point presentations of every talk given at past DENIMs will be made available to the community.

History of the ISNIE

The International Society of Neutron Instrument Engineers (ISNIE) was established in September of 2017. The idea for the ISNIE emerged because of the very successful conferences, held annually, called the Design and Engineering of Neutron Instrument Meeting (DENIM), first held in 2011. During DENIM each year, the community reaps the benefits of building relationships and sharing expertise amongst the relatively small group of professionals who represent about twenty neutron facilities worldwide. So rather than limit this interaction to once a year, the International DENIM committee (IDC) concluded that all the benefits of DENIM and more can be achieved year-round through an International Society and hence the ISNIE has been born.

Who can join the ISNIE?

Membership in the ISNIE is available to any individual interested in the free and open discussion of neutron instrument engineering! All you must do is sign a pledge to accept the values of the society.

Please note that employees and owners of for-profit organizations are only eligible for Corporate Membership. Corporate Members are ineligible to be members of the Board of Directors and are restricted from some society resources.

The advantages of joining

The ISNIE will enable you to exchange ideas and share knowledge and lessons learned with your peers! It will also give you access to the ISNIE website which includes:

  • Forums with dedicated topics- share your knowledge & learn from others!
  • Jobs postings
  • Neutron instruments with fast access to neutron instrument engineers
  • Useful tips and other information for “new” neutron instrument engineers
  • A list of upcoming relevant workshops and congresses
  • Past DENIM presentations & future DENIM event information
  • Information about the Companies that Support our Community
