What is the Sorby Centre for Electron Microscopy?
The Sorby Centre has a comprehensive series of electron microscopes, ranging from basic machines for training and routine use to high performance instruments for high level research. In particular, the Sorby centre houses 'state of the art' electron microscopes, a FEI Tecnai 20 transmission electron microscope (TEM) designed with a computer controlled goniometer so that advanced tilting and diffraction experiments may be performed, a JEOL JSM 3010 300kV TEM which is dedicated to high resolution electron microscopy with a `point to point´ resolution of 0.17 nm and a FEI Sirion Field Emission Gun scanning electron microscope (FEGSEM) with electron backscattered diffraction system (EBSD). The Sirion has a unique in-lens detection system that allows ultra-high resolution imaging in both secondary and back-scattered modes at voltages down to 500V. Each machine is equipped with an energy dispersive X-ray detector to perform local compositional analyses. As a consequence, the presence of these three instruments allows complete structural and microstructural characterisation of materials from the micro to the nanoscale. Examples of the types of images and research that can be achieved by these machines are shown below.
The Sorby Centre and its staff believe that training PhD students and post doctoral workers in the operation of SEM´s and TEM´s is a vital component of its function and with suitable instruction all researchers are able to undertake their own microstructural investigations. Basic training on three additional 'workhorse' instruments such the Philips EM420 TEM´s and Camscan and JEOL SEM´s is available to all students on request. Specialist training for advanced users on the high performance machines is then subsequently permitted.
The Sorby Centre is pleased to under take microanalysis for external customers to any standard required allowing complete structural and microstructural characterisation of materials from the micro to the nanoscale. Whether you require full sample preparation, analysis and data interpretation, or just advice we would be happy to hear from you. Any enquiries related to consultancy work should be made in the first instance to the Sorby Centre manager Prof W M Rainforth.
