AB  - The Extremely Brilliant Source (EBS) is a low emittance storage ring based lightsource installed at the ESRF. The EBS storage ring is built with more than one thousand small aperture magnets, including dipoles with stair-like field profile, combined dipole-quadrupoles, high gradient quadrupoles and higher order multipole magnets. All of these magnets were magnetically characterized and fiducialised with Moving Stretched-Wire (MSW) measurement benches developed at the ESRF. The multipole strengths of all magnets, including curved combine magnets, were obtained from MSW measurements. A detailed fiducialisation uncertainty analysis was made and estimated to about 20 µm for the bench and 33 µm when the mechanical shimming of the magnet axis is taken into account. Measurement and fiducialisation statistics will be shown and compared to design expectations.
