ISIS is a world-leading centre for research in the physical and life sciences at the STFC Rutherford Appleton Laboratory near Oxford in the United Kingdom. Our suite of neutron and muon instruments gives unique insights into the properties of materials on the atomic scale. 

We support a national and international community of more than 3000 scientists for research into subjects ranging from clean energy and the environment, pharmaceuticals and health care, through to nanotechnology and materials engineering, catalysis and polymers, and on to fundamental studies of materials.

Major Instrument and Accelerator Projects

Target Station 2 Phase 2

2015 will see both the capacity and capability of ISIS increase with two new instruments coming online. Target station 2 started operation in 2008 with 7 neutron instruments, and now two new instruments, ChipIR and Larmor have received first neutrons and are beginning their commissioning phases. A further two instruments, IMAT and ZOOM, are under construction.

ISIS First Target Station Project

The ISIS First Target Station (TS1) has now been operating for over 30 years. During this period, there has been no significant work carried out to maintain or develop the internals of TS1. The ISIS First Target Station project aims to refurbish much of TS1 to ensure its continued operation for many years into the future.

TOSCA and MAPS guide projects

Design on the new guides for Maps and Tosca has started with the aim of having the upgraded instruments running sometime in 2016.

Replacement of muon beamline magnets

The ISIS muon facility has been operating since 1987, and some of the muon beamline magnets were second-hand then – they are now over 50 years old in some cases. During the long shutdown in 2014/5, the quadrupoles near the muon target will be replaced.

Linac Tank 4 Replacement

The ISIS linear accelerator (linac) consists of 4 radiofrequency (RF) accelerating tanks, accelerating hydrogen ions generated in the ion source to 37% of the speed of light before feeding them into the synchrotron for final acceleration. Tanks 1 and 4 were built at RAL in 1976, for ISIS’ predecessor, Nimrod. They are now showing their age, so a project is underway to replace tank 4 by 2018.

Refurbishing part of the first target station proton beamline (EPB1)

EPB1 is made up of 68 magnets all of which are roughly 50 years old. Many of the electrical windings of these magnets are deteriorating (especially in high radiation-dose areas near the downstream end of EPB1). Replacement of magnets upstream of the muon target and between the muon target and the neutron target will take place during the 2014/15 shutdown.

Polystyrene C60 Composites
Perfectly imperfect: why it pays to mix it up with nanoparticles

Tuesday 20 June 2017

The discovery of bucky balls (the spherical molecules of Buckminsterfullerene, C60) in 1985 led to a Nobel Prize (in 1996) and the development of a new branch of chemistry, sending ripples through disciplines as diverse as astrochemistry, superconductivity and materials science.

Topological excitations in a quantum magnet
Evidence of topological excitations in a quantum magnet

Thursday 15 June 2017

Condensed matter physics is the study of how matter can organise itself. The different forms a material can take are called phases, and these phases determine the properties of the material – for example metals, magnets, insulators or superconductors.

Investigating the origin of excellent thermoelectric behaviour in Cu2Se

Wednesday 07 June 2017

In a world that is trying to balance an ever-increasing demand for electricity with a reduction in carbon emissions, energy efficiency is a hot topic. Researchers are keen to find ways to exploit the thermoelectric effect, wherein a temperature difference across a thermoelectric device leads to a voltage difference, in essence turning heat into electricity.

Son et lumière: neutrons illuminate the secrets of our musical heritage

Friday 24 March 2017

All cultures have music in some form, and the instruments used to produce it - and the tonal qualities they are designed to produce – change over time. Historical instruments are an important part of our cultural heritage, and scientific examination can help us to determine lost details about how the instruments were manufactured, and when, and provide us with important information to assist with their conservation.
