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.
We are pleased to announce the Deuteration for Neutron Scattering (DEUNET) workshop, organised jointly by the STFC Deuteration facility and the DEUNET European Deuteration Network, which will be held at the Oxford Spires Hotel, Oxford, UK from 15-17th of May 2017.
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.
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.
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.
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.
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.
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.
Metal-amine solutions have been a fascinating curiosity since their discovery by Sir Humphry Davy in 1808. These colourful ‘metal solutions’ are in a class of their own because they contain solvated electrons, and therefore offer us the opportunity to study fundamental physical phenomena.
A mystery surrounding three stone-like objects found within the pelvic region of a 12,000-year-old human skeleton has been solved thanks to the analytical capability of the UK’s neutron beam research facility.
Scientists from the Universities of Bath and Cambridge have developed a new, green synthetic route for cerium oxide (ceria) – an important component in catalytic converters and solid oxide fuel cells – using neutron diffraction to determine the mechanism of reaction.
