Synchrotron light: A success story over six decades

Synchrotron radiation research continues to be a major factor in the progress of science and technology, as it has been for more than half a century. We present different aspects of its history, starting with an unconventional approach: a fictional version, which should bring to light the reasons that make this field so broadly important. Then, we narrate the real history from three different points of view: the progress of electron accelerators, the evolution of synchrotron-based experiments, and the human factors. Finally, we discuss the present situation, characterized by the arrival of a new generation of sources with exceptional performances: the x-ray free electron lasers (x-FEL’s).
