The front third of the linac is undergoing an extreme makeover, metamorphosing into a first-of-its-kind hard x-ray free-electron laser, the Linac Coherent Light Source (LCLS). But even with the engineering magic embodied by hi-tech vacuum chambers, magnets, undulators and diagnostic equipment from top labs across the country, the LCLS will stand idle without one final, crucial piece of the puzzle: electrons.
