Core Functions
IMPACT (The Interaction of Materials with Particles and Components Testing experimental facility) and PRIME (Particle Radiation Interaction with Matter Experiments) facilities 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 to investigate radiation-induced modification of materials and surfaces with applications to fusion science, nanotechnology and detector development.The philosophy behind experiments in IMPACT/PRIME relies heavily on its ability to provide a wide array of characterization techniques and conditions that properly simulate complex environments. The IMPACT/PRIME 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.
