On 27 March 2002 an agreement was signed between the UK government, the Research Councils and the Wellcome Trust, making Diamond Light Source Ltd a reality. Over ten exciting years the project has grown from five people in a shared office to a working synchrotron facility. Operations began in 2007 and since then the synchrotron has been generating the brightest source of X-rays in the UK, used by thousands of scientists every year. Over the course of 2012 Diamond will be hosting a series of open days and other special events to celebrate the achievements of the facility so far and plans for the future. This special edition website will stay live throughout 2012.
