The European Synchrotron Radiation Facility (ESRF) is a research facility located in Grenoble, France. It produces intense beams of synchrotron radiation, which are used for a variety of scientific studies. This radiation is generated when charged particles, such as electrons, are accelerated to nearly the speed of light and forced to change direction. ESRF supports a wide range of research fields, including materials science, biology, and chemistry. Scientists use the facility to investigate the structure and properties of materials at the atomic and molecular levels, leading to advancements in technology and medicine.
