The ESRF-EBS (Extremely Brilliant Source) will have an electron beam horizontal emittance less than 150 picometer-radian.  The project is presently in the procurement phase. The major components of the new 7BA storage ring such as magnets and vacuum chambers are being manufactured.  The new storage ring lattice components will be installed during 2019 with the commissioning phase starting in December 2019.

The magnet lattice will include a number of Permanent Magnet (PM) based structures such as Dipoles with Longitudinal Gradients (DLs).  For the photon sources the migration to the new lattice will keep the Insertion Device (ID) source points identical to present locations, and in the majority of cases, the present ID layout in different straight sections will be used for the initial operation of the ESRF-EBS.  However, a large demand for small-gap undulators such as In-Vacuum Undulators (IVUs) and Cryogenic Permanent Magnet Undulators (CPMUs) is presently being anticipated. 

Because of the unavoidable reduction of the magnetic field strength at the dipole magnets the photon performance for hard X-rays of bending magnet beamlines is significantly reduced.  To overcome this issue, dedicated short magnetic structures, such as Short Bending Magnets (SBM), and two or three pole wigglers (2PW, 3PW) have been studied and proposed for different bending magnet beamlines.
