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

Prof. Philippe Collon

Tuesday September 15th 2015 - 7:00 pm ET

101 Jordan Hall of Science

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.

A live demonstration of X-ray spectroscopy and stargazing (if clear).
