Five years ago, the brightest source of X-rays on the planet lit up at SLAC. The Linac Coherent Light Source (LCLS) X-ray laser's scientific and technical progress since its momentous "first light" have been no less luminous, say those who have played a role in its success.

A new tool for analyzing mountains of data from SLAC’s Linac Coherent Lightsource (LCLS) X-ray laser can produce high-quality images of important proteins using fewer samples. Scientists hope to use it to reveal the structures and functions of proteins that have proven elusive, as well as mine data from past experiments for new information
