This webinar explores how next-generation magnetic confinement technologies improve the performance, stability, and quantitative accuracy of atom probe tomography experiments.
Led by presented by Nick Crnkovich and Dr. Kieran Rivers, University of Wisconsin, this session demonstrates how controlled magnetic environments significantly improve sample trajectory stability, reduce measurement uncertainty, and increase mass resolving power—key parameters for high-fidelity 3D nanoscale analysis.
Learn how enhanced magnetic confinement helps mitigate field evaporation artifacts, stabilizes ion trajectories, and enables more robust calibration workflows. By improving data quality at the source, this technology enhances traceability, facilitates compliance with ISO measurement standards, and opens up new analytical possibilities for research and industrial laboratories.
⭐ Key learnings will include:
- Why materials are the key bottleneck to commercial fusion energy
- What extreme environments fusion materials must survive (plasma exposure, high-energy neutron irradiation, and ultra-high heat flux)
- How APT reveals atomic-scale degradation mechanisms in these conditions
- Insights into transmutation product clustering in tungsten
- How APT uncovers phase separation in complex, multi-component alloys
- Why APT is a critical tool for accelerating fusion materials development

🎙️ About the speakers:
Nick Crnkovich, PhD candidate in the Department of Nuclear Engineering and Engineering Physics at University of Wisconsin - Madison is a fourth year PhD candidate in the Department of Nuclear Engineering and Engineering Physics at the University of Wisconsin – Madison. His research focuses on the development of structural materials with enhanced radiation tolerance, usually compositionally complex alloys, through ion beam irradiation experiments and characterization with TEM, APT, and other techniques. His work finds applications for both fusion and fission, and he is also a NASA Space Technology graduate research fellow focusing on materials for nuclear thermal propulsion.
Kieran Rivers , Postdoctoral Research Associate at University of Wisconsin - Madison, has recently started as a postdoc at the University of Wisconsin-Madison focusing on APT and TEM for fission and fusion materials. He completed his PhD in Materials Science at the University of Oxford where his research focused on APT of irradiation damage in tungsten for fusion applications. |
