The Terrestrial Cosmogenic Nuclide Facility is a partner lab of AEL AMS Laboratory, and is one of three facilities in Canada that are currently producing cosmogenic nuclide targets, and one of only four facilities in the world to prepare targets for all four cosmogenic radionuclides (10Be, 14C, 26Al, 36Cl) used for Earth Surface Processes research. The TCN facility group is interested in a range of scientific problems in geomorphology and landscape evolution. These problems include stream incision and sediment flux, fault kinematics and seismic slip history, tectonic geomorphology, glacial geochronology, permafrost processes and ice dating, landslide and rock avalanche research, chronology for archeology and paleontology. We collaborate with researchers at universities and insititutions worldwide, and conduct service work for geological surveys (e.g. GSC Atlantic, GSC Ottawa, USGS, Norway).
