The Beam Physics and Astrophysics Group is developing tools to produce and accelerate intense charged-particle beams, and is investigating dynamical processes that influence the evolution of these beams. The Group also investigates galactic dynamics and matters concerning the large-scale structure of the Universe.
NIU participates in the D0 experiment at Fermilab and the ATLAS experiment at CERN.
The NICADD detector group is involved in the development of hardware and software for the future electron positron linear collider.
NIU is initiating R&D efforts in medical physics.
