The construction and delivery of the EBS magnets is complete, marking a major milestone four years into the project.
Over 1000 new magnets have been produced for the innovative new storage ring, which will be transformed from the old double-bend lattice design to a brand new hybrid multibend achromat (HMBA) with seven bending magnets per cell.
The revolutionary new design, which will deliver an X-ray beam 100 times more brilliant and coherent than before, requires squeezing twice as many magnets into the existing space as compared with the old machine, so many magnets have had to be redesigned to be more compact and to generate stronger magnetic fields.
Many of the magnets push engineering technology to the limits, taking advantage of today’s better materials and increased expertise.
ASD director and EBS project leader Pantaleo Raimondi said, ”When you think of a synchrotron, the magnets are often the first components that come to mind. The magnets of the EBS project stand out in terms of innovation, from the combined function dipole-quadrupoles to the permanent magnet dipoles or high gradient quadrupoles. This reflects the capacity of the ESRF team to move forward in magnet technology.”
With the magnets ready, the next important steps of the project approach. On 10th December 2018, the last beam of the old machine will fade away and teams will have 18 months to dismantle the existing accelerator and install and commission the new magnet lattice, before bringing the new Extremely Brilliant Source online in September 2020.
