For the first time in the Synchrotron or FEL world, the large bending needed to focus the beam will be coupled with a cooling system, since the full FEL power is delivered through all of the optics to the sample. In this paper we will discuss the key design elements of the KB mirror system. We will cover the flexure hinge based bender mechanism which provides a well-defined axis of rotation. The flexure based twist and height correction mechanisms which allow correction for manufacturing and assembly tolerances. The parallel leaf spring lever arms which allow the use of relatively low bending forces with high resolution and do so while maintaining a constant direction of force application. The epoxy joint which was designed to minimize the tensile loading of the epoxy to increase its performance. We will then go on to discuss the cooling scheme which allows us to mechanically decouple the cooling system from the mirror. PB - JACoW Publishing CP - Geneva, Switzerland ER -
