Next Generation Multi-Dimensional X-Ray Imaging

我们之前的平台资助（PG）旨在开发残余应力和成像单元，以扩展我们的测量和成像能力，超越现有的时间和长度尺度，并成为世界领先的中心。这一目标现在已经实现。我们研究的国际影响力获得了高等教育领域最负盛名的奖项——女王高等和继续教育周年奖（2012-2014），获奖理由是“对电力、交通和其他关键行业至关重要的材料的x射线成像新技术”。此外，我们刚刚获得了HEFCE的1800万英镑和EPSRC的420万英镑的资本投资，以实现我们仪器的跨越式发展。这种PG更新将使我们能够发明新的，并开发新兴的技术，以看到以前从未以这种方式看到的3D事件。这将最大限度地发挥资本投资的效益，将x射线和电子成像结合在一起，以检查材料在苛刻环境下的行为。许多仪器将是全新的。PG将使我们拥有一个由数学家、探测器专家、仪器开发人员和应用材料科学家组成的多学科团队，以探索新的制度和承担新的科学。例如，通常x光照片是黑白的（就像医院里的x光片一样）。我们已经研制出一种能看到“颜色”的探测器。这将使我们能够在3D图像中“看到”物体的组成。通常x射线成像可以看到不同的相，但不能看到组成材料的颗粒。最近，我们与丹麦和格勒诺布尔欧洲同步加速器的科学家们一起开发了一种方法，可以无损地观察样品内部的不同颗粒。目前，这必须在大型设施中使用同步加速器x射线来完成-我们将开发一个能够做到这一点的实验室系统。最后，我们最近获得了5个EPSRC博士培训中心，我们将培训这些博士生我们通过PG开发的成像技术。

Our previous platform grant (PG) was aimed at developing the residual stress and imaging unit to extend our measurement and imaging capability beyond existing time and length scales and to become a world leading centre. This has now been achieved. The international impact of our research was recognised by the award of the most prestigious prize in the HE sector, the Queen's Anniversary Prize for Higher and Further Education (2012-2014) for "New Techniques in X-Ray Imaging of Materials Critical for Power, Transport and Other Key Industries." Further we have just been awarded £18m by HEFCE and £4.2m by EPSRC for capital investment to achieve a step jump in our instrumentation.This PG renewal will enable us to invent new, and develop emerging, techniques to see in 3D events that have never been seen this way before. This will maximise the benefit of the capital investment bringing together X-ray and electron imaging to examine materials behaviour under demanding environments. Many of the instruments will be completely new. The PG will enable us to have a multidisciplinary team of mathematicians, detector experts, instrument developers and applications materials scientists to explore new regimes and undertake new science. For example, normally X-rays pictures are collected in black in white (just like the x-ray radiographs in hospitals). We have developed a detector that can see in 'colour'. This will enable us to 'see' the composition of the objects in our 3D images. Normally X-ray imaging can see different phases but not the grains making up the materials. Recently together with scientists in Denmark and at the European Synchrotron in Grenoble we have developed a method to see the different grains inside a sample non-destructively. Currently this must be done using synchrotron X-rays at large facilities - we will develop a laboratory system capable of this. Finally we have recently been awarded an 5 x EPSRC Centres for Doctoral Training and we will train these PhD students in the imaging techniques we develop through the PG.
