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.
The ISIS Molecular Spectroscopy Group and ILL Computing for Science Group will hold the next MDANSE (Molecular Dynamics and Lattice Dynamics to Analyse Neutron Scattering Experiments) workshop at the Cosener’s House, Abingdon, UK from the 10th to 12th of November 2016.
ISIS Graduate, Jon Elmer, joined his fellow RAL Graduates to star in BBC2’s Robot Wars last night, in one of 40 teams battling it out to become the show’s 2016 champion. The RAL graduate team, completed by Laurence de Bruxelles (RAL Space), Sean Cleary (Team Captain; Technology) and Dominique Anderson (Robot Pilot; Central Laser Facility), spent four weeks staying late after work to design and build their Robot, Sweeny Todd.
The Royal Institution has produced three short films about accelerator science as part of ‘Accelerators for humanity’, a project supported by an STFC Public Engagement Large Award. The first film, released today, explores what is needed to keep the ISIS particle accelerator running and the people that make it happen.
ISIS has available a limited number of 50%-funded studentships available to UK users to run from October 2017. A full description of this studentship scheme plus instructions on how to apply is available and the deadline for requests is 16 October 2016.
Research into the interactions between water and pharmaceuticals has resulted in a young researcher winning the B.T.M. Willis Prize for neutron scattering. The ongoing research, which takes place at the Institut Laue-Langevin, the Bragg Institute and ISIS Neutron and Muon Source, will impact on the pharmaceutical industry by improving the efficiency of the process of new drug compounds reaching the market.
The Indian Minister for Science and Technology and Earth Sciences visited the ISIS Neutron and Muon Source during a trip to the UK to mark the start of new partnerships between the UK and India research communities.
At 4pm today, Zoe Bowden, ISIS Deputy Director, opened R108, the new helium recovery building at ISIS. This is the first stage in a cost reduction programme that will see liquid helium from the many cryogenic experiments at ISIS recycled for use elsewhere in the facility as helium gas, which could save the organisation up to £500k per annum.
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.
As we move away from our dependency on fossil fuels and work towards cleaner energy resources and chemical conversion it is key to further our understanding of catalysis. Whether it’s assisting reactions in energy transformations, providing chemicals with increased efficiency or getting rid of, or preventing, waste, catalysis will help in the move towards a greener future. Progress in catalytic science and its applications requires an understanding of what is taking place with the catalyst at the molecular level, which is where techniques such as neutron scattering are invaluable.
Materials that display localised electronic or magnetic behaviour are of wide interest in physics. One reason is that they can provide insights into unusual quantum phenomena, as seen in single molecular magnets for example. An international group of scientists have been using neutrons to study calcium ferrate to understand how different magnetic arrangements are distributed throughout the material. Surprisingly they found that the phases existed in tiny regions only a few nanometres across, containing localised waves of magnetic excitations. This discovery could lead to the use of magnetic materials in a similar fashion to photonic crystals.
World-leading neutron scientists gathered last week to discuss the latest findings in the development of drugs to tackle infectious diseases and antibiotic resistance. The annual UK Neutron and Muon Science and User Meeting (NMSUM) was hosted in Warwick, UK, and brought together researchers using the neutron instruments at the ISIS Neutron and Muon Source, UK, and the Institut Laue-Langevin (ILL) in France.
Scientists have created a model of a leaf’s waxy surface, similar to those found in wheat crops, in a project supported by the agrochemical company, Syngenta. They are now using the model at ISIS to study how surfactants, a key component in pesticide formulations, interact with the leaf surface to get into the plant and take effect. The results could lead to the fine-tuning of pesticide formulations to further increase crop yields in an attempt to meet the demand of feeding an ever growing global population.
