The ESRF designs a new generation of synchrotron

After the succesful delivery of the first phase of its upgrade programme (2009-2015), the ESRF has launched, on May 2015, the ESRF – Extremely Brilliant Source (ESRF – EBS) project: this project is focused on the construction of a new and highly innovative 844 metres storage ring. It represents an investment of 150M€ over the period 2015-2022.

The ESRF Extremely Brilliant Source is a new challenge taken up together by the 22 partner nations of the ESRF. With the construction and commissioning of the first of a new generation of synchrotrons, fully conceived and designed by ESRF accelerator scientists and engineers, the ESRF consolidates and enlarges its pioneering role in X-ray science. This challenging and unique project will pave the way to provide new tools for the investigation of condensed matter and life science, which will better worldwide scientific cooperation and the quest to finding durable answers to the great technological, economic, societal and environmental challenges facing our society.

Francesco Sette, Director General of the ESRF


A technological and scientific challenge

The ESRF – EBS is a global project that will boost the ESRF partner countries position at the forefront of X-ray science and instrumentation. The ESRF – EBS centers around four main pillars:

  • The construction of a new – the first of a kind – storage ring, inside the existing infrastructure, with performances 100 times superior to present day synchrotrons
  • A new state-of-the-art beamlines portfolio and users’ support facilities adapted to the new research opportunities
  • An important instrumentation programme, in particular for the development of new high performance X-ray detectors
  • An ambitious “data as a service” strategy in order to fully exploit the high performance of the new X-ray source

A revolutionary lattice

EBS new storage ring is based on a ground-breaking lattice concept, the Hybrid Multi-Bend Achromat (HMBA) or Raimondi lattice (Figure 2), which has become the design basis of most future fourth-generation synchro- tron sources in the world. The new lattice will improve the brilliance of the ESRF light source by a factor of 100 while ful lling the constraint to keep the original beamline infrastructure, thanks to an innovative magnet design. With its larger dynamic aperture, smaller sextupole settings, and smaller emittance with respect to previous proposals, the HMBA lattice has made a large impact on the light source community. The ESRF’s Accelerator and Source Director, Dr. Pantaleo Raimondi, was recently awarded the 2017 Gersh Budker Prize by the European Physical Society Accelerator Group (EPS-AG) for the invention of the Hybrid Multi-Bend Achromat (HMBA) lattice.
