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:
- Improved mass resolving power and data fidelity through optimized magnetic fields
- Reduced trajectory aberrations for more accurate 3D reconstructions
- Enhanced stability in evaporation conditions across challenging materials
- How magnetic confinement supports quantitative nanoscale analysis beyond conventional methods
