The second building, the Diamond Light Source, is the United Kingdom’s national synchrotron science facility, located at the Harwell Science and Innovation Campus, near Oxford. The Diamond’s 561 meter-diameter ring, which gives the building its distinctive circular shape, covers an area in excess of 43,300 square meters. Diamond is one of the most advanced scientific facilities in the world. It works like a giant microscope, harnessing the power of electrons to produce bright light that scientists can use to study anything from fossils to jet engines to viruses and vaccines.
