SLACSLAC’’s main programs ares main programs are……

Photon Science and Synchrotron Photon Science and Synchrotron RadiationRadiation

The use of ultra high-intensity x-ray beams (10 million times the intensity of x-ray tubes) for studies in physics, biology, chemistry, medicine, and environmental science.

Linac Coherent Light Source Linac Coherent Light Source (LCLS)(LCLS)

Provide laser radiation in the x-ray region that is 10 orders of magnitude greater in peak power and peak brightness than any existing x-ray light source.

High Energy Physics High Energy Physics Particle/Particle AstrophysicsParticle/Particle Astrophysics

Experiments, theory, accelerator development.
