“…Performing an extensive set of simulations with the BEaTriX simulation code and modeling variable levels of optical finishing, [19] this time up to a 45 arcsec HEW for the mirror (which was not far, indeed, from the initial quality of the pre-formed mirror), [15] we obtain the trends in Figure 13. The vertical collimation, essentially depending on the source size, is the least sensitive to the mirror quality.…”

The BEaTriX (Beam Expander Testing X-ray) facility, being assembled at INAF-Brera Astronomical Observatory, will represent an important step in the acceptance roadmap of Silicon Pore Optics (SPO) mirror modules, and so ensure the final angular resolution of the ATHENA X-ray telescope. A paraboloidal mirror, manufactured at INAF-Brera, will provide a collimated X-ray beam to a monochromating system and to a beam expansion unit, enabling the full illumination of the mirror modules under test with a broad, highly monochromatic, and parallel X-ray beam. Such a beam will be used to directly diagnose SPO modules in their focusing performances. This requires, indeed, the expanded beam to have a divergence smaller than the expected angular resolution of the modules under test. This condition is subject, in turn, to the optical quality and to the alignment of the optical components. Aiming at establishing the final angular resolution that can be reached and the respective fabrication/positioning tolerances, we have been dealing with a comprehensive set of optical simulations. Modeling based on wave optics and ray-tracing was carried out to predict the collimation performances of the paraboloidal mirror, including the effect of surface errors obtained from metrology. Ray-tracing routines were subsequently employed to simulate the full beamline. This paper reports the simulation results and the methodologies we have adopted.

The next generation X-ray observatory ATHENA (Advanced Telescope for High ENergy Astrophysics) requires an optics with unprecedented performance. It is the combination of low mass, large effective area and good angular resolution that is the challenge of the X-ray optics of such a mission. ATHENA is the second Large Class mission in the Science Programme of ESA, and is currently in a reformulation process, following a design-to-cost approach to meet the cost limit of an ESA L-class mission.The Silicon Pore Optics (SPO) is the mission enabler being specifically developed for ATHENA, in a joint effort by industry, research institutions and ESA. All aspects of the optics are being addressed, from the mirror plates and their coatings, over the mirror modules and their assembly into the ATHENA telescope, to the facilities required to build and test the flight optics, demonstrating performance, robustness, and programmatic compliance.The SPO technology is currently being matured to the level required for the adoption of the ATHENA mission, i.e., the start of the mission implementation phase. The monocrystalline Silicon material and pore structure of the SPO provide this optics with excellent thermal and mechanical properties. Benefiting from technology spin-in from the semiconductor industry, the equipment, processes, and materials used to produce the SPO are highly sophisticated and optimised.
