Description
One of the major projects at the Paul Scherrer Institute (PSI) for the next years is the upgrade of the Swiss Light Source (SLS2) in order to provide higher photon flux and brilliance for the beamline users. The new storage ring Multi Bend Achromat lattice aims at an improvement in emittance and an associated increase in brightness by a factor of forty compared to the current performance while maintaining the locations of the undulator based beam lines and the circumference of 287.25 m. This requires an extremely dense lattice arrangement with a total of 888 electromagnets and 450 permanent magnets. All four types of electromagnets and seven types of permanent magnets have been designed and will be measured at PSI until the end of 2023.
This contribution provides an overview of the design of the SLS2 magnets and presents the magnetic measurement systems dedicated for their characterization, before showing exemplary measurement results for the 70 A Electro-Quadrupole magnet series QS2A, QS2B, QS2F and QS2G measured with an 18 mm rotating coil measurement system.
