This webinar, presented by Nick Crnkovich and Dr. Kieran Rivers, will explore how atom probe tomography (APT) is being used for the development of materials to enable commercial scale fusion power.
Fusion energy faces a number of obstacles before it can reach commercial scale, but one of the largest is the development of new materials able to withstand the harshest environments ever created by humans. Plasma facing components will experience degradation from plasma exposure, radiation damage from neutrons at much higher energies and fluxes compared to fission, and heat fluxes an order of magnitude higher than a jet engine.
In this webinar, we will learn about the materials challenges presented by fusion and APT’s role in overcoming them. From identifying the clustering of transmutation products in tungsten to identifying phase separation in compositionally complex alloys, APT is a critical tool in a critical field.
Tuesday February 17 10AM CST.

Presenters:
Nick Crnkovich
PhD candidate in the Department of Nuclear Engineering and Engineering Physics
University of Wisconsin - Madison
Nick Crnkovich 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.
Dr. Kieran Rivers
Postdoctoral Research Associate
University of Wisconsin - Madison
Dr. Kieran Rivers 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.
