	Funding: This work is partially supported by the EC under the CESSAMag project, FP7 contract 338602. 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.

THPMR035	Low Horizontal Beta Optics for ALBA	3461
	G. Benedetti, J. Campmany, Z. Martí ALBA-CELLS Synchrotron, Cerdanyola del Vallès, Spain
	The ALBA insertion device beamlines have a horizontal and vertical rms source size of 130 and 5.5 microns. Protein crystallography beamlines (Xaloc) would benefit from a reduction of the horizontal and increase of the vertical beam size, to gain spatial resolution and avoid anisotropy effects. A modified lattice with horizontal and vertical beam size of 74 and 9 microns has been setup and tested, breaking the ring symmetry, with different setting of the six neightbouring quadrupoles at each side of the Xaloc insertion device. Such configuration keeps the nominal emittance almost unvaried and the working point is recovered by small changes in the quadrupole strengths of the four symmetric matching sections. A dedicated setting of the nine available sextupole families has been obtained by numerical optimization of the dynamical apertures and tune shifts. The lattice settings have been satisfactorily tested. The measured lifetime is reduced a factor two and the injection efficiency decreases to 60%. Finally, the option of increasing the number of sextupole families, to recover the dynamic aperture and guarantee the injection efficiency, has been studied.
