The ion beam laboratory and scanning probe microscopy team

Team Leader: Yongqiang Wang

The team supports and conducts cutting-edge research in ion-solid interactions, ion beam analysis, ion implantation, and radiation damage effects. The work involves varied activities and specific research, including the following capabilities and goals:

• Provide centrally accessible ion beam instrumentation for materials modification and characterization for LANL researchers, maintained and upgraded by experts;
  
• Build, preserve, and upgrade the knowledge and skills required for the optimal operation and customized research capability in ion beam materials research;
  
• Train LANL researchers, post-docs, and students to skillfully apply ion beam techniques and instrumentation to their research; and
• Provide ion beam services to DOE CINT users and other entities external to LANL.
