Extreme conditions X-ray diffraction and imaging beamline ID15B on the ESRF extremely brilliant source

We present, in this overview article, the main features of the ID15B beamline on the new ESRF Extremely Bright Source (EBS). The ID15B beamline was fully reconstructed in 2015, considering the new capabilities of the future EBS machine. We will introduce the ID15 project, the ID15B undulator X-ray source, the optical scheme and the experimental hutch. The beamline ID15B is mostly dedicated to the determination of structural properties of solids at high pressure using angle-dispersive diffraction with diamond anvil cells. We present different selected research examples illustrating the capabilities of this instrument.
