Yo' coherent light source is so fat, it takes 37 seconds to trace the electron's beam path—in fast forward.

The Linac Coherent Light Source is no dainty piece of machinery. Its magnet-lined tracks stretch over the course of a half-mile and accelerate electron pulses to 99.9999999 percent of the speed of light. The brightest X-ray beam ever built, the LCLS is powerful enough to image viruses and turn aluminum samples into 2 million-degree plasma in a trillionth of a second.

And if you are looking to take the scenic route, here is the LCLS tour in a leisurely 73 seconds:
