MODELING RESULTS FOR THE ALBA BOOSTER

The 3rd generation light source ALBA is in the process of being commissioned. The full energy 3 GeV booster synchrotron was commissioned during 2010, ramping the beam extracted from the linac at an energy of 110 MeV to the 3 GeV required for injection into the storage ring. The lattice is based in combined function bending magnets, providing a small emittance beam at extraction. This paper reviews the agreement between the optics modeling and the measures performed during the commissioning, with special regard to the tune, chromaticity and emittance measurement along the ramping process. The results from the magnetic measurements of the combined magnets during the ramping are included in the model to explain the movement of the tunes during the ramp.
