“Accelerator Mass Spectrometry, from Ocean circulation 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 archaeological artifacts, to the birth and death of stars.
In this talk, we will explore the research performed in the Nuclear Science Laboratory at Notre Dame. In particular, we 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.
