Within the MooNpics project, a special mirror holder for long X-ray mirrors was developed that provides reproducible and well defined mounting conditions in each participating laboratory. The goal is to understand mechanical and stress influences and hence to improve mounting methods. Before the actual start of the roundrobin, measurements were done to investigate the influence of the mirror mounting. A procedure was developed to reduce the induced stresses and increase the reproducibility with regard to the planned round-robin. |
