The more than 50 synchrotron light sources now in operation around the world include facilities in Brazil, Korea, and Taiwan which started their programs in the 1980's when they were developing countries. They came on line in the 1990's and have since trained hundreds of graduate students locally, without sending them abroad and losing many of them. They have also attracted dozens of mid-career diaspora scientists to return. Their growing user communities have demanded more advanced facilities, leading to the funding of higher performance new light sources that are now coming into operation. Light sources in the developing world now include the following: SESAME: A collaboration of 8 countries in the Middle East (Cyprus, Egypt, Iran, Israel, Jordan, Pakistan, Palestinian Authority, and Turkey) uses scientific cooperation to promote peace and understanding in the Middle East – an excellent example of Science Diplomacy. Under the umbrella of UNESCO and modelled on CERN. It started research in 2018. www.sesame.org The African Light Source, in planning stage.
