| Zusammenfassung | The development of X-ray reflective mirror coatings for the NewAthena optics focuses on achieving the required effective area and ensuring full compatibility with the Silicon Pore Optics technology. Platinum and carbon coating designs have been demonstrated to be suitable for NewAthena, providing good performance across the 0.1 to 10 keV energy range. Multilayer coatings applied to the outermost optics rows can further improve the 6 to 7 keV performance but increasing the number of bilayers N also results in longer coating times. This has motivated an investigating of the trade-off between coating time and high-energy performance. We present two initial approaches to reduce coating time by limiting N for each optics row and evaluate their effect on the effective area at 6.8 keV. Results of X-ray characterisation of representative trilayer and multilayer mirror coatings are presented, including compatibility with the required wet chemistry and annealing processes. |
