This course is intended for undergraduate and postgraduate students, who are interested in the application of accelerator mass spectrometry to the Geosciences. Dr. George Burr, the key joint lecturer, will discuss both theoretical and practical aspects of AMS and the measured isotopes and their applications. Accelerator Mass Spectrometry (AMS) was first introduced as an analytical method in the late 1970s. AMS is one of the most sensitive analytical tools available today. It is used primarily for the study of cosmogenic isotopes, including 14C, 10Be, 26Al, 36Cl and 129I, among others. The course is divided into three parts. The first part of the course will discuss the theoretical design, implementation, and refinement of AMS instruments. The second part of the course will focus on significant geologic findings made possible by AMS technology. The third part of the course will discuss current challenges, latest findings, and future directions in the field. Paper reading and discussion will play essential roles in class.
