This educational website, FusEdWeb, provides access to resources that explain the fundamentals of nuclear fusion. It offers an online fusion course, fusion and plasma glossary, student and teacher resources, and links to other fusion-related websites. The text is accompanied by numerous charts, diagrams, and images. Major topics include energy sources and conversions, two key fusion processes, how fusion reactions work, creating the conditions for fusion, plasmas, and achieving fusion conditions. FusEdWeb was created by the Contemporary Physics Education Project (CPEP), a group of educators and physicists who create materials for introductory physics courses.
