Abstract
Development and qualification of X-ray reflective mirror coatings for the NewAthena mission is progressing with a focus on enabling scientific capabilities of the telescope, given the updated requirements of the redefined mission. In this work, we consider both design and development of Ir/C multilayer coatings optimised to ensure the required performance across the spectral range, facilitating the mission science objectives. We present demonstration of manufacturing capability for the optimised Ir/C multilayer coatings, and compatibility with the Silicon Pore Optics (SPO) technology. Characterisation of X-ray mirror coatings is performed using X-ray reflectometry with a focus on mirror design qualification and long-term stability.
