However, the long mirror length leaded large size of the overall mechanism and the limited height space for multi-dimensional adjustment makes the mechanical design of the KB system with both stability and functionality difficult. In this KB system, each mirror is bent by a four-bar bender universally used in HEPS to obtain the required profile. A combination of parallel and serial mechanism with totally 11-DOF is designed to realize the adjustment requirements. Specifically, the parallel mechanism is a three-point support design that serves as the base of the KB mirror chamber and offers coarse tuning of 5-DOF, exhibiting great compactness and high stiffness. The series mechanism is a stacking of four angle and two displacement adjustment mechanisms up to 6-DOF. These independent stages with high resolution are assigned to VFM and HFM respectively to achieve fine adjustment of their relative positions. In the design of each angle and displacement adjustment stage, the height and rigidity of the mechanism are also fully considered. PB - JACoW Publishing CP - Geneva, Switzerland ER -
