 | | Dr. Heinrich Bräuninger, Garching, Germany, began his preliminary studies on ROSAT in 1973, concentrating his work on reducing the micro-roughness of the X-ray mirrors. On this basis, microroughness of 0.25 nm was achieved in an iterative program lasting several years, during which Carl Zeiss gradually improved the polishing technology. These systematic investigations into X-ray scattering were complemented by theoretical studies. |

 | | Dr. Bernd Aschenbach, Garching, Germany, developed flexible beam tracing programs for real mirrors which are deformed by thermal- mechanical action and are subject to reflection losses due to chemical contamination. This made it possible to make a precise prediction regarding the X-ray optical quality of the ROSAT mirrors. In addition, he proposed a technique for the assembly of the parabolic and hyperbolic mirrors, ensuring maximum compensation of the mirror errors resulting from production. |
