With up to a million X-ray flashes per second, 8,000 times more than its predecessor, it transforms the ability of scientists to explore atomic-scale, ultrafast phenomena that are key to a broad range of applications, from quantum materials to clean...

Chemical reactions often involve intermediate steps that are too fast and complex for us to see  – even using our most advanced scientific instruments. Combining two X-ray spectroscopy techniques has now been shown to change that.

In the decade since LCLS produced its first light, it has pushed boundaries in countless areas of discovery.

A team led by SLAC scientists combined powerful magnetic pulses with some of the brightest X-rays on the planet to discover a surprising 3-D effect that appears linked to a mysterious phenomenon known as high-temperature superconductivity.

Experiment Shows Potential of X-ray Laser to Study Complex, Poorly Understood Materials

John Hill watched with eager anticipation as controllers ramped up the power systems driving SLAC's X-ray laser in an attempt to achieve the record high energies needed to make his experiment a runaway success.

After five night shifts of shooting pairs of X-ray pulses through soups of fine sand and gold, Aymeric Robert was tired but exhilarated. The first experiment with an instrument he helped bring into being – the X-ray Correlation Spectroscopy (XCS)...
