The CELLS is an approved project to build a national synchrotron light source in Spain. The main goals of the project are to provide a medium energy machine (3 GeV) with low emittance and top up operation, a circumference of ~280 m and at least 12 straight sections available for experiments. At present, two lattices are being considered. The first one is based in QBA optics and provides and emittance of 5 nm-rad, using existing technologies. The second one is a TBA one, with an emittance of 2 nm, where physical aperture are reduced by at least a factor 2 and gradients in the bending magnets are up to 10 T/m. We present the selected lattice, and review the main beam dynamics (energy acceptance, errors) issues.

In May of 2003 the Spanish and Catalan Governments established a public Consortium for the construction, equipment and exploitation of a third generation Synchrotron Light Source. The foundation was based upon a proposal from 1997 to build a 2.5 GeV, 12-fold symmetry machine with a circumference of around 260 m. At present a re-design is being considered, based upon the following decisions: 1.) Electron energy of 3 GeV, 2.) Circumference around 280 m, 3.) Emittance smaller than 5 nm.rad, 4.) 16-fold symmetry lattice 5.) Full energy injector, 6.) Topping-up injection mode foreseen and 7.) Booster synchrotron and Storage ring housed in the same tunnel. Lattice considerations are given in an accompanying paper. In the present one we will give a project overview and explain key design decisions and overall schedule. Five beamlines will be design and construct in a first phase to cover the needs of the Spanish community. The definition of these beamlines will take place during 2004 involving the users community. Planned beam commissioning will be in 2009.
