First accumulation and world record horizontal emittance of 308 pm


News from EBS. Sunday 15 December 2019, at 15:35, the EBS team was able to accumulate electrons in the EBS storage ring at the world record horizontal emittance value of 308 pm. The commissioning continues.

"My warmest congratulations to all those who contributed to this crucial milestone in the EBS storage ring commissioning, coming only 13 days after the start of the storage ring commissioning and beamline restart phase, that began on 2 December 2019. " said Francesco Sette, ESRF Director General.

EBS is a 150 M€ ESRF upgrade programme over 2015-2022, highlighted as a landmark in the ESFRI (European Strategy Forum on Research Infrastructures) roadmap and centred around the construction of a brand-new synchrotron source, based on a brand-new storage ring concept fully developed at the ESRF. State-of-the-art beamlines, an advanced instrumentation programme and a data-management implementation plan – required for the efficient exploitation of the new source – complement the programme.

EBS will be the first high-energy fourth-generation synchrotron, with X-ray performance increased by a factor of 100 compared to previous parameters. EBS relies on an important number of key innovative technologies and solves a decades-long puzzle for the implementation of stable and highly performing diffraction-limited high-energy storage rings. EBS programme efficiently re-uses 90% of previously existing infrastructure, and addresses best practices to lower the ESRF carbon footprint. The new and original EBS concept is based on a Hybrid Multiple Bend Achromat (HMBA) lattice design, which is now paving the way to a new generation of synchrotrons.
