When was the stanford linear accelerator built
It was also a look ahead at the lab's continuing evolution and growth into new frontiers of scientific research that will keep it at the forefront of discovery for decades to come.
Department of Energy Office of Science. Panofsky Gregory A. Employee Portal Research Resources. SLAC History. A history of discovery. These discoveries and others that reshaped our understanding of matter were empowered by a series of colliders and detectors: The Positron-Electron Project PEP , a collider ring with a diameter almost 10 times larger than SPEAR, ran from The Stanford Linear Collider, completed in , allowed scientists to focus electron and positron beams from the original linear accelerator into micron-sized spots for collisions.
The SLC hosted a decade of seminal experiments. About Our Name. Logo Resources. News Center. He stands in front of a clean room sealed to keep contaminants away from delicate electronics.
Here is an illustration of the wide swath of night sky the LSST will be able to photograph in a single image. It's big enough to photograph the entire sky every three or four nights, so astronomers and astrophysicists can track changes in the appearance and position of stars, galaxies and solar system objects. SLAC is assembling the camera's image sensor, made of square, megapixel sensors, each 42mm on edge. Hogan describes how SLAC's accelerator components work.
The biggest pipe behind him houses laser beams that ensure the accelerator components stay aligned correctly. When X-ray laser experiments are under way at the LCLS, scientists leave the experimental rooms, close the doors, and oversee the activity from control rooms. Visitors to SLAC are greeted with a large aerial photo showing the accelerator stretching in a straight line west of Stanford University and underneath Interstate Stephen Shankland Nov.

SLAC X-ray Correlation Spectroscopy experiment Purple tracks let researchers steer a camera at the X-ray Correlation Spectroscopy XCS experiment station through a wide range of angles and distances to measure light scattered off subjects blasted with X-ray lasers. Older SLAC accelerator chamber This section of SLAC shows the basic structure of a linear accelerator: modules built side by side, each giving electrons a bit more of a speed boost. SLAC Klystron Gallery This above-ground building, called the Klystron Gallery, contains nearly klystrons that generate microwave energy that's piped underground into the accelerator chamber to speed up electrons.
SLAC microwave copper waveguide SLAC accelerates electrons and positrons with bursts of high-power microwave energy originating from dozens of devices called klystrons.
SLAC accelerator magnetic quadrupole A quadrupole magnet uses magnetic "lenses" to focus the high-energy electron beams to a width about one-tenth the diameter of a human hair. SLAC leakproof vacuum pipe SLAC's electron beam must travel through a vacuum, or else acceleration would be limited by short-circuit problems.
SLAC simulation This SLAC simulation, run inside a massive supercomputer, shows a phase of the universe's formation when the blasting output from the ionized interstellar hydrogen gas of new stars. SLAC access hatch to accelerator chamber The original access ladders down to the linear accelerator chambers look like like they belong in a submarine.
SLAC's two-mile accelerator This view shows SLAC's two-mile linear accelerator, looking east from the point where electrons begin their quick trip to near light speed. SLAC control room When X-ray laser experiments are under way at the LCLS, scientists leave the experimental rooms, close the doors, and oversee the activity from control rooms. There's a device containing plasma and molten lithium that doubles the acceleration of the particles pictured here with Hogan.
And there's this device , which uses magnetic power for the accelerator rather than against it, hoping to further focus the electrons. The Linac Coherent Light Source is an X-ray producing, free electron laser that sheds enough light to see things on almost an atomic level before ultimately destroying samples, of course.
SLAC has been observing photosynthesis in the act with this kind of hardware. The setup cost the university half a billion dollars to build. It's a partial reconstruction of the last third of the original linear accelerator, but it uses a separate "injector. It happens to be the most powerful device of its kind in the world. Pictured above is one of the magnets that prevents the electron beam from becoming too wide.
The beam eventually makes it to this hall, where all the undulators reside—appropriately named the Undulator Hall. Each section contains magnetic poles, three centimeters each, that wiggle the beam in order to produce the X-ray beam.
In total there are 33 of these in operation, keeping things crucially aligned. In unison, these produce 10 billion times more light than just one undulator could alone. Vertical shot of the room here ; tour co-guide John Bozek pictured in each. He also happens to be an atomic, molecular, and optical instrument scientist.
The SLAC team accepts proposals for projects to utilize the space in addition to their own work real scientists at work here in the room nearby.
