The spin of the electron plays an important role in many phenomena in condensed matter physics. Spin and angle-resolved photoemission is a powerful tool to determine the spin resolved band structure and Fermi surface of a variety of material types, especially in combination with synchrotron radiation.In order to extent the measurement possibilities of our spin and angle resolved photoemission set-up at the Swiss Light Source, a new sample manipulator is requested. The proposed manipulator can reach significantly lower temperatures, can be stabilized at any given temperature, has six degrees of freedom (three spatial directions and three rotational axis) and consists purely of non-magnetic materials.This will allow us to measure complex condensed matter phases and novel materials at low temperatures, such as the (quantum) spin Hall effect, momentum dependent spin-structures in low dimensional systems induced by the Rashba effect and related spin-orbit-interaction induced effects, superconductivity and other phases where the spin of the electron is expected to play an important role. Furthermore, the extra degree of rotational freedom of the new manipulator will allow us to measure smaller samples, previously inaccessible regions in reciprocal space and to perform symmetry operations which are currently impossible.The realm of experimental possibilities will be greatly enhanced by the implementation of this new sample manipulator, combined with the unique detection set-up currently available this can constitute the next leap forward in spin and angle resolved photoemission and thus in the understanding of many physical phenomena.
