Abstract

With the introduction of the multi-bend achromats in the new fourth-generation storage rings the emittance has decreased by an order of magnitude resulting in increased brightness. However, the higher brightness comes with smaller beam sizes and narrower radiation cones. As a consequence, the requirements on mechanical stability regarding the beamline components increases. Here an innovative five-Axis parallel kinematic mirror unit for use with soft X-ray beamlines using off-Axis grazing-incidence optics is presented. Using simulations and measurements from the HIPPIE beamline at the MAXIV Laboratory it is shown that it has no Eigen frequencies below 90Hz. Its positioning accuracy is better than 25nm linearly and 17-35μrad angularly depending on the mirror chamber dimensions.
