Accelerator Mass Spectrometry: From Tracing Ocean Currents to the Life and Death of Stars

Evolving from methods and techniques developed in nuclear physics, accelerator mass spectrometry (AMS) is a highly sensitive detection technique developed to search for the proverbial nuclear "needle in the haystack." Using this method, we can identify specific isotopes to investigate phenomena from ocean current flows, to the age of archeological artifacts, to the birth and death of stars.

In the talk, we will explore the research performed in the Nuclear Science Laboratory at Notre Dame. In particular, we will focus on tracing Atlantic Ocean circulation, galactic radioactivity, and the early formation of the solar system. Join us as we identify materials in the universe around us with a demonstration of testing everyday objects.

Following the presentation, enjoy stargazing on the Jordan Hall rooftop (weather permitting).

Our Universe Revealed: Physics for Everyone Lecture Series aims to provide an avenue to access current physics research and an opportunity for everyone to expand their understanding of the universe around us.
