How the ALS Works
Electron bunches traveling at nearly the speed of light, when forced into a circular path by magnets, emit bright ultraviolet and x-ray light that shines down beamlines to experiment endstations.
How Bright Is It?
The ALS produces light in the x-ray region of the electromagnetic spectrum that is one billion times brighter than the sun. This extraordinary tool offers unprecedented opportunities for state-of-the art research in materials science, biology, chemistry, physics, and the environmental sciences.
Ongoing research topics and techniques include
