Abstract
| In this work we present the results of the measurement campaign of the main bending magnets of the SESAME storage ring, that were fully characterized at ALBA-CELLS magnetic measurements facility. A total of 17 combined function dipoles ' 16 series magnets plus a pre-series one ' has been tested and characterized. This campaign has been performed using a dedicated Hall probe bench. The main measurements include the transfer function at the center of the magnet and field maps of the three components of the field in a plane around the nominal trajectory of the electron beam, at two different operating currents. In this paper we describe the experimental setup and procedures, before reporting the main results, including statistics of magnet-to-magnet reproducibility and integrated field quality. Finally, we show how the measured data can be exploited for an optimal 3D alignment of the dipoles in the machine. |
