Nuclear and Particle Physics and Applications is composed of three teams.
The High Energy Nuclear Physics team studies nucleon structure and the matter formed in high energy heavy ion collisions, using the Relativistic Heavy Ion Collider facility at BNL, the Large Hadron Collider at CERN, and the Fermilab accelerator facilities.
The Neutron team studies fundamental symmetries using neutrons at the LANSCE Ultracold Neutron facility and the Spallation Neutron Source at ORNL.
The Low Energy Nuclear Physics team exploits the unique characteristics of intense beams of neutrons at the Weapons Neutron Research Facility and Lujan Center as well as protons at Target 2 to study nuclear structure and reactions of interest to both fundamental and applied physics.
P-3 operates the Ultracold Neutron Source (UCN) facility at LANSCE and carries out experiments in fundamental and applied physics at UCN.
