About Us

Diamond Light Source is the UK’s national synchrotron; a huge scientific facility designed to produce very intense beams of X-rays, infrared and ultraviolet light. Our scientists use the light to study a vast range of subject matter, from new medicines and treatments for disease to innovative engineering and cutting-edge technology.

At Diamond we are currently undertaking a major upgrade of the facility, known as Diamond-II. Diamond-II combines a new machine and new beamlines with a comprehensive series of upgrades to optics, detectors, sample environments, sample delivery capabilities and computing, which will ultimately generate an even more brilliant light source at a higher energy.
