General-purpose compact synchrotron radiation sources

Abstract

General-purpose sources of synchrotron radiation are proposed to satisfy those future needs of basic, applied and industrial research as well as of industrial production which cannot be covered adequately by the existing machine types. Their spectrum extends into the hard X-ray range. They feature a mixed lattice composed of superconducting and normal conducting bending magnets, and dispersion-free straight sections to accommodate insertion devices. The mixed lattice offers an additional way of minimizing the emittance by optimizing the distribution of bending angle among the different types of bending magnets. At an energy of 1.5 GeV the emittance in a six-period triple bend achromat lattice can be brought into the 10 −7–10 t-8 m rad range.
