The European Synchrotron Radiation Facility (ESRF), located in Grenoble - France, is a joint facility supported and shared by 22 countries, which started operation in 1994. The ESRF operates the most powerful synchrotron radiation source in Europe. Each year nine thousand researchers travel to Grenoble where they work in a first-class scientific environment to conduct exciting experiments at the cutting edge of modern science.
The ESRF is currently engaged in a major upgrade, the EBS (Extremely Brilliant Source) project, centred on the construction of a brand new storage ring - the world's first high-energy fourth-generation synchrotron light source.
Back in 2009, the ESRF embarked upon an ambitious and innovative modernisation project, the Upgrade Programme, implemented in two phases: Phase I (2009-2015) and the ESRF-EBS (Extremely Brilliant Source) (2015-2022) programmes. With an investment of 330 million euros, the Upgrade Programme is paving the way to a new generation of synchrotron storage rings, that will produce more intense, coherent and stable X-ray beams.
The first phase of the Upgrade (from 2009 to 2015) achieved the following:
The second phase (2015-2022) aims to deliver:
The ESRF operates 30 public beamlines and hosts 13 CRG beamlines, so 43 beamlines in total.
The annual budget for operating the ESRF is around 90 million Euros (not including funds dedicated to the Upgrade programme).
About 700 people work at the ESRF.
About 9000 researchers come each year to the ESRF to carry out experiments.
Applications for beam time:
Around 2500 applications are received each year for beam time at the ESRF.
Our users and staff publish about 2000 papers annually on work carried out at the ESRF.

Standard and BAG proposals:
Long Term Project proposals:
In the case where any of these dates falls on a Friday, Saturday or Sunday, the deadline will automatically move to the following Monday at midnight.
Details for the next calls for standard ESRF proposals are on the web at: http://www.esrf.fr/UsersAndScience/UserGuide.
The ESRF is currently not in operation due to the EBS upgrade programme and so, with the exception of some experiments on the Cryo-EM, no user experiments have been cancelled.
Rapid access for COVID-19 related research
The ESRF is ready to provide rapid access to its facilities for COVID-19 related research projects, including the Cryo-EM electron-microscopy platform, the MASSIF-1 macromolecular X-ray diffraction beamline, and Partnership for Structural Biology facilities. This exceptional access will be granted with the aim to contribute to the international scientific effort to overcome the COVID-19 pandemic. More details as well as information on how to apply can be found here.
