“…The optical design of the X-ray collimator is based on a Wolter I configuration of about 1.1 m in length and an average grazing incidence angle of about 0.4 • , 9,10 . Mirror mechanical design consists of two separate sections for the parabolic and hyperbolic profiles of the Wolter collimator, respectively (Fig.…”

“…Among the different subsystems comprising the VERT-X facility those that mostly contribute to the HEW measure systematic error budget are considered the most critical. 10 These parts, namely the parallelizing mirror and the X-ray source, both mounted on the raster scan vertical tube, together with the raster scan rotation and translation frames are under development.…”

The mirror assembly of the ESA New - Advanced Telescope for High-ENergy Astrophysics (New-ATHENA) will be the largest x-ray optics ever built. Indeed, its unprecedented size, mass and focal length create great difficulties for the ground calibration. The VERT-X project aims at developing an innovative calibration facility which will be able to accomplish to this extremely challenging task. The design is based on a 2.5 cm2 parallel beam produced by an x-ray source positioned in the focus of a highly performing collimator. In order to cover the whole mirror, the beam will be accurately moved by a raster-scan with the capability to tilt up to three degrees in order to test the off-axis performance and the out of field stray-light. The whole system is enclosed in a cylindrical vacuum chamber about 20 m high and with a diameter ranging from 7 to 4 m. By design, VERT-X will be able to measure the New-ATHENA mirror half energy width (HEW) with a precision of 0.1”, all over the field of view, with the source size, the collimator error and the raster scan tracking accuracy being the most important terms of the error budget. The VERT-X project, started in 2018, is financed by ESA and conducted by a consortium that includes INAF together with EIE, Media Lario, BCV Progetti and Apogeo Space. This paper presents the current state of the development and manufacturing of the most critical systems of the facility, namely the raster-scan mechanism and the source-collimator vertical assembly.

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.

Silicon Pore Optics (SPO) uses commercially available monocrystalline double-sided superpolished silicon wafers as a basis to produce mirrors that form lightweight high-resolution X-ray optics. The technology has been invented by cosine Measurement Systems and the European Space Agency (ESA) and developed together with scientific and industrial partners to mass production levels. It leverages techniques and processes developed over decades by the semiconductor industry to handle, process, and clean silicon wafers and plates. SPO is an enabling technology for large space-borne X-ray telescopes such as Athena and ARCUS, operating in the 0.2 to 12 keV band, with angular resolution aiming for 5 arc seconds. SPO has also shown to be a versatile technology that can be further developed for gamma-ray optics, medical applications and for material research.
