The SLAC Linac
Al Baker, former Area Manager for Accelerator Systems, inside the SLAC linear accelerator, or linac, in 2002. At two miles long, the linac was the world's longest linear accelerator and could accelerate electrons to 99.9999999% of the speed of light. Two thirds of the copper accelerator, roughly 2km, still operate, while one third has been removed to make way for a state-of-the-art superconducting accelerator to drive the LCLS-II X-ray laser upgrade.
