🤩 SLAC National Accelerator Laboratory runs a linear particle accelerator. Today, scientists and engineers at SLAC use the accelerator to generate a very powerful X-ray laser. Such a refined X-ray light beam is used to penetrate deep into matter at the molecular and atomic level, and allows scientists to produce "movies" of the behavior of these atoms and molecules. Generally it's very difficult to look at atoms and see how they behave and that's why SLAC built this X-ray laser. Technically it'
