ATHENA X-ray Optics Development and Accommodation

The ATHENA (Advanced Telescope for High ENergy Astrophysics) mis s ion studies and techno logy preparation are continuing to progress. The optics for this future space ob servatory is based on the Silicon Pore Optics (SPO), and is being evolved in a joint effort by industry, research institutions and ESA. The SPO technology uses the superb properties of monocrystalline Silicon, and spins in technologies developed for the semiconductor industry, benefiting from excellent materials, processes and equipment. In a holistic approach the technical and programmatic challenges of the ATHENA optics are being addressed simultaneously. A comprehensive Technology Development Plan (TDP) was defined and is being implemented to develop this novel X-ray optics technology. The performance, environmental compatibility and serial automated production and testing are being addressed in parallel, aiming at the demonstration of the required technology readiness for the Athena Mission Adoption Review (MAR) expected in 2022.
