Saturn particle beam fusion accelerator at Sandia National Labs in Albuquerque, New Mexico. Saturn uses a series of capacitors to build and store electrical charges, discharging them as an electrical pulse that drives strong currents through a target area. These currents generate a magnetic field that "squeezes" objects in the target area. Saturn can produce 85 terawatts of power, more than 50 times the output of the U.S. utility grid. X-rays and data generated inside Saturn and other Sandia accelerators are used to test three-dimensional computer codes that simulate what happens inside a nuclear weapon when it detonates.
