. It has an annual budget of around 80 million euros, employs over 600 people and is host to more than 3500 visiting scientists each year.

Research in the ESRF focuses, in large part, on the use of X-ray
X-ray
X-radiation is a form of electromagnetic radiation. X-rays have a wavelength in the range of 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz and energies in the range 120 eV to 120 keV. They are shorter in wavelength than UV rays and longer than gamma...

Protein
Proteins are biochemical compounds consisting of one or more polypeptides typically folded into a globular or fibrous form, facilitating a biological function. A polypeptide is a single linear polymer chain of amino acids bonded together by peptide bonds between the carboxyl and amino groups of...

Crystallography
Crystallography is the experimental science of the arrangement of atoms in solids. The word "crystallography" derives from the Greek words crystallon = cold drop / frozen drop, with its meaning extending to all solids with some degree of transparency, and grapho = write.Before the development of...

Beamline
In particle physics, a beamline is the line in a linear accelerator along which a beam of particles travels. It may also refer to the line of travel within a bending section such as a storage ring or cyclotron, or an external beam extracted from a cyclic accelerator.In materials science, physics,...

Laboratory
A laboratory is a facility that provides controlled conditions in which scientific research, experiments, and measurement may be performed. The title of laboratory is also used for certain other facilities where the processes or equipment used are similar to those in scientific laboratories...

, preparation suites, and offices connected to the ring by a pedestrian bridge. The linear accelerator electron gun and smaller booster ring used to bring the beam to an operating energy of 6 GeV are constructed within the main ring. Until recently bicycles were provided for use indoors in the ring's circumferential corridor. Unfortunately they have got removed after some minor accidents. But even before it was not possible to cycle continuously all the way around, since some of the beamlines exit the hall.

The ESRF site forms part of the "Polygone Scientifique", lying at the confluence of the Drac
Drac River
The Drac is a 130 km long river in southeastern France, left tributary of the Isère. It is formed by the confluence of the Drac Noir and the Drac Blanc, that both rise in the southern part of the Massif des Écrins. It flows through several reservoirs, including the Lac de Monteynard-Avignonet....
