The FinEstBeaMS beamline is under construction at the 1.5 GeV
storage ring of the MAX IV Laboratory at Lund, Sweden. It has been
designed to cover an unusually wide energy range from ultraviolet (4.3
eV) to soft X-rays (1000 eV) but experiment will also be possible at the
Mg and Al Ka energies. Instead of having two insertion devices and a
deferent optical scheme for low and high photon energy regions, we have
based our design on a single long-period, elliptically polarizing
undulator and a plane grating monochromator. This solution will provide
very good conditions for planned experiments in the whole photon energy
region. The beamline will have two branches: one will be used to
investigate free atoms, molecules and clusters with photoelectron/photoion
coincidence spectroscopy as well as solids with photoluminescence
spectroscopy whereas the other one will be dedicated to ultra-high vacuum
studies of surfaces and interphases, utilizing X-ray photoelectron
spectroscopy and X-ray absorption spectroscopy. This paper focuses on the
optical design of the beamline and general design concepts of the gasphase
and solid-state end stations.
