The Americas host some of the world’s most productive light sources, concentrated in the national laboratories of the United States, with major facilities in Canada and Brazil. They span the full range of the field — from veteran soft and hard X-ray synchrotrons to a brand-new fourth-generation ring and two of the world’s leading X-ray free-electron lasers.
