Radiation Interaction with Materials (neutrons, electrons, particles, laser and photons)
Researcher: Prof. Nasr Ghoniem
Radiation interaction with materials results in the generation of copious amounts of defects. Some of these defects “anneal-out,” as a self-healing process. However, a fraction is usually trapped, forming harmful structures in the material, such as gas bubbles or unwanted brittle phases. Research in Ghoniem’s lab addresses how and where radiation deposits its energy and comes to rest in the material. Specialized computer simulation tools (Monte Carlo, Phase Field, and Rate Theory) are developed to describe the formation of the harmful effects of radiation in structural materials, as shown below.
