cosine partners with SRON to pioneer X-ray interferometry for groundbreaking space observation

cosine and SRON, the Netherlands Institute for Space Research, have recently signed a collaboration agreement. The collaboration focuses on cosine’s pivotal role in the manufacturing and delivery of extremely precise X-ray mirrors for the development of an X-ray interferometer demonstrator.

This collaborative venture aims to push the boundaries of space observation by harnessing the promises of X-ray interferometry. The X-ray interferometer testbed, designed by SRON, will try to demonstrate the feasibility of X-ray imaging in space with ultra-high resolution. A single spacecraft interferometer could achieve 100 microarcsecond resolution, comparable to the Event Horizon Telescope’s performance, creating potential for groundbreaking discoveries. A constellation of X-ray interferometers in space could even potentially reach resolutions below one microarcsecond, enabling imaging at an unprecedented level of resolution.

Under this new contract, cosine will produce and deliver the highly precise X-ray mirrors at the heart of the prototype X-ray interferometer. The project will be led by cosine’s High Energy Optics (HEO) development team and executed at our cutting-edge facilities in Sassenheim, The Netherlands.

Based on SPO technology
The X-ray interferometer leverages cosine’s Silicon Pore Optics (SPO) technology, developed by cosine in collaboration with the European Space Agency (ESA) for the NewAthena mission. This enables cosine to build upon its extensive knowledge and experience gained through development projects for the NewAthena mission, showcasing our company’s ability to translate research and development into tangible solutions with far-reaching implications.

X-ray interferometry holds immense potential for a myriad of astronomical applications, including testing general relativity, measuring cosmological parameters, and studying phenomena such as gamma-ray bursts and supermassive black holes, all within the confines of a compact spacecraft.
