History of Fermilab
● originally named the National Accelerator Laboratory
● On May 11, 1974, the laboratory was renamed ● Two major components of the Standard Model of
Fundamental Particles and Forces were discovered at Fermilab– the bottom quark (May-June 1977)
– top quark (February 1995).
– the first direct observation of the tau neutrino In July 2000
Fermilab Mission
“Fermi National Accelerator Laboratory advances the understanding of the fundamental nature of matter and energy by providing leadership and resources for qualified researchers to conduct basic research at the frontiers of high energy physics and related disciplines. “

Experiment at Fermilab
● The best chance for a discovery in the next five years that would change the direction of particle physics is at Fermilab experiments.CDFDZero
● Astrophysics experiments explore the interactions of quarks and the cosmos
● Fermilab contributes to the Large Hadron Collider at CERN.
