Located at the University of Saskatchewan in Saskatoon, the Canadian Light Source (CLS) is a national research facility and one of the largest science projects in Canada's history. The CLS speeds up electrons to produce intensely-bright synchrotron light that allows scientists to study materials at a molecular level. Over 1,000 researchers from around the world use the CLS every year. The CLS offers free public tours several times a week and you can reserve your tickets online. On your tour, you'll learn about the facility’s history, how its technology works, and examples of how researchers have used the facility to conduct groundbreaking research in the fields of health, agriculture, the environment, and advanced materials.
