Design considerations for a Swiss Light Source (SLS)

An outline of a design of an intense VUV to X-ray synchrotron light source at the Paul Scherrer Institute (PSI) is presented. Envisaged is a machine with very flexible parameters allowing several modes of operation. Among them: very small emittance (∼1nm) at lower energies; high flux, high photon energy operation at the maximum possible energy of around 2 GeV; a bypass option for production of very short pulses with possible operation of a single pass high gain FEL. Under study is the incorporation of superconducting bending magnets into the lattice to increase the critical photon energy into the. The lattice accommodates two long straight sections (∼20m each) for flexible use of insertion devices including the production of switchable circularly polarized light.
