Fermi National Accelerator Laboratory (Fermilab), located just outside Batavia, Illinois, near Chicago, is a United States Department of Energy national laboratory specializing in high-energy particle physics.
The Compact Muon Solenoid (CMS) experiment is one of the largest international scientific collaborations in history, involving 4300 particle physicists, engineers, technicians, students and support staff from 182 institutes in 42 countries (February 2014).
The CMS is a general-purpose detector at the Large Hadron Collider (LHC). It has a broad physics programme ranging from studying the Standard Model (including the Higgs boson) to searching for extra dimensions and particles that could make up dark matter. Although it has the same scientific goals as the ATLAS experiment, it uses different technical solutions and a different magnet-system design.
For almost two decades, Fermilab and its scientists have played a significant role in the Large Hadron Collider (LHC) and particularly in the CMS experiment. Fermilab also provides scientific, technical and organizational support for the 630 scientists and graduate students from 47 US universities and laboratories that participate in the 2,600-member international CMS collaboration.
Fermilab hosts one of 11 Tier-1 computing centers that process data for the CMS experiment and support the research activities of scientists across the country and around the world. It also hosts a Remote Operations Center, where more than 100 scientists conduct thousands of hours of remote shifts for the CMS experiment each year, and the LHC Physics Center, a hub for CMS physics in the United States.
