ESRF EBS storage ring and new opportunities in synchrotron science.
The presentation reviews the ongoing Upgrade Programme (UP) of the ESRF, which was launched in 2009 in two phases. The first phase is concluded, and it delivered 19 new instruments aiming to develop X-ray science in the study of the structure and dynamics of condensed and living matter down to nanometer space resolution, and time-scales down to the nanosecond in the ESRF Purple Book (http://www.esrf.fr/Apache\_files/Upgrade/ESRF-SciTechProg2008-2017.pdf). The ongoing second phase is centred on the construction of the first of a new generation of storage rings for synchrotron science. This new hybrid multiple bend achromat storage ring lattice design efficiently enables the delivery of diffraction-limited hard X-rays by drastically reducing the electron beam horizontal emittance; its adaptation to the existing ESRF storage ring tunnel will improve today's performances by 100 in terms of brightness and transverse coherence. This exciting project, following the footsteps of the MAX-IV multiple bend storage ring implemented in Lund, has been under construction at the ESRF for two years and will be operational in 2020. This ESRF Extremely Brilliant Source (EBS) programme has attracted worldwide attention, triggering similar conceptual studies in almost all existing and future synchrotron laboratories on the planet. The ESRF Orange Book (http://www.esrf.eu/Apache\_files/Upgrade/ESRF-orange-book.pdf) describes the whole ESRF EBS programme including the new scientific investigation opportunities. The ESRF-EBS will deliver a new and first-of-a-kind storage ring, new adapted beamlines, and an ambitious instrumentation programme centred on X-ray detector developments and data handling strategies.
