Current Experiments
Omega Group members are collaborators on the following experiments.

  • ATLAS Experiment (CERN: Geneva, Switzerland)
      - US ATLAS Collaboration
      - ATLAS Upgrade
  • D0 (Fermilab: Batavia, Illinois)
  • Proton and Deuteron EDM Experiments at the Deep Underground Science and Engineering Laboratory
  • MicroBooNE - an experiment at Fermilab with a large Liquid Argon Time Projection Chamber (LArTPC) to be exposed to the Booster neutrino beam and the NuMI beam at Fermilab.
  • Muon g-2 experiment at Fermilab: - A proposed experiment to measure the muon anomalous magnetic moment to 0.14 ppm, a fourfold improvement over the previous Brookhaven E821 experiment.
  • The Mu2e experiment at Fermilab: - A proposed experiment to improve the sensitivity to muon-to-electron conversion by 4 orders of magnitude.
