STFC’s Rutherford Appleton Laboratory: General Public Access Day Wednesday 21st August RAL’s public access day is a terrific opportunity to see ‘behind the scenes’ at our world leading facilities. Tours of several departments will be available: ISIS The ISIS pulsed neutron and muon source is a world centre for research in the physical and life sciences. It 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’. From the original vision over 30 years ago, ISIS has become one of the UK’s major scientific achievements. As one of the world’s leading neutron and muon sources, ISIS has changed the way the world views neutron scattering. THE ISIS ION SOURCE The beam for the whole ISIS facility begins in a tiny ion source. This produces H- ions, which are turned into protons that are accelerated and used to generate neutrons. A community of more than 2000 scientists use the neutrons to research subjects ranging from aircraft wings to babies’ lungs. SPACE TESTING FACILITIES To ensure instruments survive both a rocket launch and the extreme conditions of space they need to be thoroughly tested on the ground before they start their long journey to space. Here at RAL Space we can perform these tests, and more, to ensure these sensitive instruments operate for as long as possible. Come and find out how we keep things clean, assemble them and test them in some of the UK’s leading space test facilities. ROBOT TESTING “MARS YARD” The Autonomous Systems Group at RAL Space develops terrestrial test equipment which is used to test instrumentation and software for space. The group’s eleven robots are used not only to test technologies for exploring the Moon and Mars, but also to research a large number of potential applications here on Earth. SCIENTIFIC COMPUTING Computing affects all areas our lives, and is absolutely vital to the advancement of science and technology – not to mention the economy! The Scientific Computing Department at RAL is home to large scale, state-of-the-art computing facilities, which are used to study everything ranging from data produced at the Large Hadron Collider to DNA. Image credit: CERN VULCAN CONTROL ROOM Vulcan is a unique Petawatt (1015 Watts) laser which delivers a focused beam – which for 1 picosecond (0.000000000001 seconds) is 10,000 times more powerful than the National Grid – to support a wideranging programme in fundamental physics and advanced applications. Scientists from around the globe use Vulcan to study everything from astrophysics to nuclear reactions. VULCAN TARGET AREA When the Vulcan laser fires a laser pulse, the target in the interaction chamber experiences a light intensity that is similar to taking all of the sunlight shining on the Earth and focussing it onto a pin head. The CLF’s Vulcan laser system delivers pulses of light that are so extreme in intensity that they are able to instantly rip apart and super heat matter to millions of degrees, making the centre of our interaction chambers the hottest place on the planet, albeit momentarily. The physics of what happens during this extreme interaction is explored by capturing the radiation that comes flying off at, or near to, the speed of light. ASTRA Astra is a high power, ultra-short pulse, high repetitionrate laser. It uses titanium-doped sapphire (TiS), and works at 800 nm in the near infra-red, just outside the region visible to the human eye. The pulses from Astra are so short that they are like sheets of light energy thinner than a human hair, which can be focused to a spot a few thousandths of a millimetre across. The energy they contain is thus delivered to a very small target extremely quickly, allowing experimenters to study the way matter behaves under extreme conditions of temperature and pressure. CENTRAL LASER FACILITY: TARGET FABRICATION The Target Fabrication Group works with the scientists using the Central Laser Facility to design and modify the targets of each particular experiment. They also study novel target designs and micro-assembly techniques to be able to deliver targets for the future high power lasers. CRYOGENICS The Cryogenics Group at RAL work with a wide variety of instrumentation at incredibly low temperatures. They’re involved in a huge diversity of projects – from designing components of the ATLAS detector at CERN, to manufacturing cryostats for the new Atacama Large Millimetre Array (ALMA), which studies the dust-obscured regions that are the birthplace of stars and planets. Image credit: ESO LASERS FOR SCIENCE Located in the Research Complex at Harwell, the Lasers for Science Facility (LSF) uses the very latest imaging and spectroscopy techniques to study biological and other samples. Using the OCTOPUS and ULTRA imaging clusters, anything from single molecules to whole tissues can be imaged and studied. METROLOGY The Metrology group use a suite of state-of-the-art equipment for the detailed measurements and analysis needed to solve today’s engineering problems. They produce detailed electronic reports, evaluate the hardness of materials and use the latest laser tracking systems to accomplish their work and ensure that the components produced for projects such as the ATLAS detector match up to their design with pin-point accuracy. CATAPULT The Satellite Applications Catapult Delivery Team, or Catapult, is one of seven technology and innovation centres established in the country. It is funded by the Technology Strategy Board, and works closely with RAL Space to ‘catapult’ the growth and development of satellite space technology. This commercialisation will lead to applications in many areas including marine science, renewable energy and security. ADVANCED MATERIALS The Advanced Materials group work to develop and test prototypes for many of STFC’s physics projects, both in the UK and abroad. By ensuring that all of the materials are properly and thoroughly tested, we can be sure that each particular device will function properly, even in the most challenging of environments. RESEARCH COMPLEX AT HARWELL The Research Complex at Harwell (RCaH) is a new, multidisciplinary laboratory that provides facilities for researchers to undertake new and cutting edge scientific research in both life and physical sciences and the interface between them. Scientists use a wide variety of techniques – from X-ray crystallography to transmission electron microscopy to further our understanding of the world around us.
