The ultrafast, ultrabright X-ray pulses of the Linac Coherent Light Source (LCLS) have enabled unprecedented views of a catalyst in action, an important step in the effort to develop cleaner and more efficient energy sources.
This photo shows a small fuel cell inside of a sample chamber at SLAC's SSRL. This experimental station allows scientists to study fuel cells under more realistic conditions.
SSRL’s X-rays uncovered a 6th century translation of a book by the Greek-Roman doctor Galen, allowing the hidden text to be read for the first time in a thousand years.
