SDB aims in-situ real-time diagnosis in dynamic compression science and additive manufacturing. Nano-experimental environment requires highly multilayer KB mirror system in thermal deformation and stability of mechanism. This paper illustrates the KB cooling scheme and mechanical design. Only using variable-length water cooling to control the temperature and thermal deformation of mirror has limitations here. First, the installation of cooling system should be non-contact so that the surface shape can be sophisticatedly controlled without deformation of chucking power. Second, the distance between the HKB and the sample stage is too small to arrange the cooling pipe. Third, the KB mirror has multi-dimensional attitude adjustment. Cu water cooling pipe would be dragged with adjustment thus it has to be bent for motion decoupling, which occupies considerable space. Thus, the Cu cooling block and water cooling pipe are connected by copper braid. Eutectic Gallium-Indium fills a 100 ¿m gap between the cooling block and KB mirror to avoid chunking power deformation. Finally, the structural stability and chamber sealability is analyzed.
