An eddy current septum magnet prototype for SOLEIL light source project

One of the prototypes which has been made during the 2.5 GeV synchrotron project SOLEIL design is a passive septum magnet. Standard cross section has been chosen for the three eddy current septum magnets used for the booster injection, the booster extraction and the storage ring injection of SOLEIL. A prototype for SOLEIL project has been realized. In this paper the comparison between 2d and 3d calculations (OPERA-2d, ELEKTRA) and results of magnetic measurements is presented, as well as results of thermal tests in vacuum and influence of all of these on mechanical design for the final magnet.
