Establishment of a new Electron Microprobe Laboratory

Meenu Garg • DATE: October 17, 2014

The University of Notre Dame’s Integrated Imaging Facility (NDIIF) is now home to an operational Electron Microprobe (EMP) instrument.  In brief, an EMP is a high-powered microscope that uses electrons to examine the chemical composition and morphological characteristics of samples at high spatial resolution, typically in the order of 1 to 5 microns (10-6 meters). The EMP instrument is a Cameca SX-50, which can be used to conduct fundamental research in many types of research disciplines, such as: securing our nation’s energy future; understanding the origin and evolution of Earth and the Moon; the role of biomineralization in the transport of heavy metals and radionuclides in the environment; nanoscience; understanding human bone degradation; and nuclear forensics analysis. The laboratory will operate as a recharge facility, and will be managed on a daily basis by Dr. Ian Steele, who formerly conducted research at the University of Chicago. Dr. Steele comes to Notre Dame with vast experience and expertise in EMP-related research acquired over the past ~35 years.

This initiative was led by Profs. Antonio Simonetti, Clive Neal, and Peter Burns from (CEEES) and Prof. Alex Mukaysan (Chemical & Biomolecular Engineering), and financial support provided by Notre Dame’s Office of Research, the College of Engineering, and CEEES.
