That is a zap 3.2 kilometer (2 miles)long. It is generated at the Stanford Linear Accelerator Center (SLAC), a part of Stanford University, in Palo Alto, California.a
The Stanford Linear Accelerator Center (SLAC) is a United States Department of Energy National Laboratory operated by Stanford University under the programmatic direction of the U.S. Department of Energy Office of Science. The SLAC research program centers on experimental and theoretical research in elementary particle physics using electron beams and a broad program of research in atomic and solid-state physics, chemistry, biology, and medicine using synchrotron radiation.
The 3.2-kilometer (2.0-mile) long underground accelerator is the longest linear accelerator in the world, and is claimed to be "the world's straightest object."
The above-ground klystron gallery atop the beamline is the longest building in the United States, shown in this long-exposure photo with traffic streaming overhead on the I-280 freeway.
Founded in 1962, the facility is located on 1.72 square-kilometers (426 acres) of Stanford University-owned land on Sand Hill Road in Menlo Park, California—just west from the University's main campus. The main accelerator, a 3.2-kilometer-long RF linear accelerator, which can accelerate electrons and positrons up to 50 GeV, has been operational since 1966. It is buried 10 metres (30 feet) below ground and passes underneath Interstate 280.
There is a lot of stuff and things going on at the SLAC, so if your viewing found other things and you would like more feedback about the SLAC, visit the Virtual Visitor's Center by clicking here.
