Diamond Light Source

This week, Science Café is reporting from one of the most advanced scientific facilities in the world. We’re in Didcot, in Oxfordshire, at the rather impressively named Diamond Light Source, which is home to a huge synchrotron.

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.

Presenter Adam Walton takes a tour right inside this distinctive donut shaped building, which serves scientists across Europe. He talks to chief executive officer Andrew Harrison about some of the research at Welsh universities to have benefited from the facility. And he's reunited with Denbighshire born scientist Alun Ashton, who leads data analysis at the synchrotron - and who suggested the tour one sunny day last year at the National Eisteddfod.
