Abstract :
LISA, a Light Source for industrial and Scientific Application, has been proposed to be built in the Bonn region of Germany. For the lattice a modified “Quadrupole Bend Achromat” (QBA) will be used. The novel feature of this lattice is the application of two types of bending magnets with a vertical focusing component and different deflection angles to keep the radiation integrals small. The long bending magnets (20°) will be used in the are of the achromat and the small (10°) are foreseen to perform the matching of the twiss functions from the are to the straight sections without blowing. Up the emittance determined by the magnets in the arcs. With a sixfold symmetry, a circumference of 125 m an emittance smaller than 20 nm rad can be obtained. The natural chromaticities and the sextupole strength are moderate, the dynamic aperture is +/- 30 mm (100 σx and 170 σy), the momentum acceptance is more than +/- 9% and the tune shift with amplitude is very promising
