We performed a study to find the optimum injection scheme for SLS2 among the conventional and more advanced schemes; namely multipole kicker injection (off-axis and also on-axis matched to the off-momentum closed orbit) and longitudinal injection.

	An upgrade of the Swiss Light Source (SLS) would replace the existing storage ring by a low aperture multibend achromat lattice providing an emittance of about 100–200 pm at 2.4 GeV, while maintaining the hall, the beam lines and the injector. Since emittance scales inversely cubically with the number of lattice cells, an SLS upgrade is challenged by the comparatively small ring circumference of only 288 m. A new concept for a compact low emittance lattice is based on longitudinal gradient bending magnets for emittance minimization and on anti-bends (i.e bends of opposite field polarity) to disentangle dispersion and horizontal beta function in order to provide the optimum matching to the longitudinal gradient bends while minimizing the contribution to chromaticity.

An upgrade of the Swiss Light Source (SLS) would replace the existing storage ring by a low aperture multibend achromat lattice providing an emittance of about 100–200 pm at 2.4 GeV, while maintaining the hall, the beam lines and the injector. Since emittance scales inversely cubically with the number of lattice cells, an SLS upgrade is challenged by the comparatively small ring circumference of only 288 m. A new concept for a compact low emittance lattice is based on longitudinal gradient bending magnets for emittance minimization and on anti-bends (i.e bends of opposite field polarity) to disentangle dispersion and horizontal beta function in order to provide the optimum matching to the longitudinal gradient bends while minimizing the contribution to chromaticity.
