- Core Functions
- IMPACT facility have been designed to study in-situ dynamic heterogeneous surfaces at the nano-scale exposed to varied environments that modify surface and interface properties. These facilities are used to investigate radiation-induced modification of materials and surfaces with applications to fusion science, nanotechnology and detector development. The philosophy behind experiments in IMPACT relies heavily on its ability to provide a wide array of characterization techniques and conditions that properly simulate complex environments. IMPACT experiment achieves this by atomic-scale characterization of the evolution of elemental, chemical, and thermodynamic states of ultra-thin film surface and interfaces using complementary surface-sensitive characterization techniques.

About Us
The Nuclear Science User Facilities (NSUF) is the U.S. Department of Energy Office of Nuclear Energy's only designated nuclear energy user facility. Through peer-reviewed proposal processes, the NSUF provides researchers access to neutron, ion, and gamma irradiations, post-irradiation examination and beamline capabilities at Idaho National Laboratory and a diverse mix of university, national laboratory and industry partner institutions.
