ESRF

European Synchrotron Radiation Facility

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:

  • 19 new and refurbished beamlines with capabilities unique in the world
  • Continued world leadership for X-ray beam availability, stability and brilliance
  • Major new developments in synchrotron radiation instrumentation
  • Study for a revolutionary storage ring

The second phase (2015-2022) aims to deliver:

  • The construction of a new storage ring, the world's first high-energy fourth-generation synchrotron light source
  • The construction of new state-of-the-art beamlines
  • An ambitious instrumentation programme (optics, high-performance detectors)
  • An intensified big data strategy, designed in order to exploit the enhanced brilliance, coherent flux and performances of the new X-ray synchrotron source

Beamlines:

The ESRF operates 30 public beamlines and hosts 14 CRG beamlines, so 44 beamlines in total.

Budget:

The annual budget for operating the ESRF is around 90 million Euros (not including funds dedicated to the Upgrade programme).

Staff:

About 700 people work at the ESRF.

Visiting researchers:

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.

Scientific papers:

Our users and staff publish about 2000 papers annually on work carried out at the ESRF.

call for proposals

Deadlines

Standard and BAG proposals:

  • 1st March (for the period 16th August to 28th February)
  • 10th September (for the period 1st March to 15th August).

Long Term Project proposals:

  • 15th January each year.
Due to the long shutdown for the EBS construction, there will be no proposal deadlines in September 2018 or in 2019.
Details for the next calls for standard ESRF proposals are on the web at: http://www.esrf.fr/UsersAndScience/UserGuide
Due to its intrinsic organisation, the ESRF does not process Transnational Access proposals. Please check their website for more information.
