There are 6 in-vacuum eddy current septum magnets used for booster injection,extraction,and storage ring injection in SSRF.Special attention was paid to coils and their support designs because of the shock force they bear in the magnetic fields and the high heat which is hard to be dissipated in vacuum environment.For the storage ring magnets,good transverse homogeneity in the gap was achieved by careful design,precise machining and accurate assembly;and an extremely low leakage field on the stored beam is another key feature thanks to the high permeability Mu metal.Magnetic field measurement was conducted with both a point coil and a long integral coil,and the results agree well with the OPERA-2d/3d simulations.An inner tube is added to keep the continuity of impedance for the circulating beam with two RF finger flanges at each end.There is no vacuum separation between the inner tube and the magnet chamber.Sputter ion pumps integrated with NEG are used to acquire the UHV for the chamber.
