Low-Energy Accelerator Facility

Visit Facility  
A 50 MeV/25 kW electron linear accelerator producing a wide range of radioisotopes for medical, national security, basic science and industrial applications.
Particle accelerators use electric fields to speed up and increase the energy of a beam of particles. These particles are steered and focused with magnetic fields. The Low-Energy Accelerator Facility (LEAF) consists of an electron linear accelerator (LINAC) and a Van de Graaff (VDG) electron accelerator. Originally built in 1969, the LINAC recently underwent a significant upgrade to increase the beam power and energy. Researchers in Argonne’s Nuclear Engineering Division use the LEAF for a wide range of applications. This talented team of radiochemists, chemical and nuclear engineers, health physicists and experienced technicians supports multiple programs on behalf of sponsors such as the U.S. Department of Energy’s (DOE’s) National Nuclear Security Administration, U.S. DOE Office of Science Isotope Program and the Defense Threat Reduction Agency.
