![]() My group’s research is using these 4D images to see inside the materials as we make or use them, improving their properties. The rotation speed of the object can become the limit, since we want to look at the kinetics of processes inside objects, and by rotating at too high a speed you can change that.Īdditive manufacturing offers unprecedented control in the design and manufacture of lattice structures (Credit: MAPP) However, unlike a medical scan where the X-ray source rotates around you, at DLS you rotate the object. The maximum is about 10 times a second, and we are working to make it 100 times. ![]() This is much like a medical CAT scan but Diamond’s light is 10 billion times brighter than the Sun, allowing CAT scans to be taken at higher resolutions, seeing features at the sub-micron scale while applying a dynamic process like deformation or heat.Ī medical CAT scan takes minutes but with DLS’s bright light we can get a complete 3D scan in less than a second. The work I do at the DLS is to use these X-rays to see inside a range of materials in 4D, creating 3D images as the material changes over time. So the light goes from near-infrared, which is about the energy at which atoms in a molecule are bonded… all the way up to hard X-rays which can be even higher in energy than medical X-rays.Īs with Superman’s X-ray vision, we can see inside materials with these X-rays. When you bend them, they shed light, and the more you bend them the more intense that light is. They are put into a storage ring over half a kilometre in circumference and at each of the 48 corners is an electromagnet, which bends them. The electrons only want to do one thing: go straight. They’re actually moving so close to the speed of light that they are ageing at only 80% of the speed that we are. The DLS uses electrons, which it accelerates with a linear accelerator up to nearly the speed of light. I lead a group performing ‘4D science’ using the UK’s synchrotron source, the Diamond Light Source (DLS). Lee spoke to Joseph Flaig about how the scans reveal the inner secrets of materials, helping to create the turbine blades and car engines of tomorrow. Using the incredibly bright Diamond Light Source, his team creates ‘4D’ scans of objects – 3D scans that change over time. ![]() Peter Lee from the University of Manchester looks inside materials to make them stronger, lighter and more reliable. ![]()
