“…Each radius demonstrates different aspects of the optics, from very long (110 mm) and narrow (50 mm) mirror plates at the innermost radius, to very short (20 mm), but wide (102 mm) plates of the outer mirror modules. X-ray testing of recent optics takes place at two facilities: One is the XPBF 2.0 (X-ray parallel beam facility) [10,11], operated by PTB at the BESSY II synchrotron radiation facility. The other is the PANTER facility operated by the Max Planck Institut für extraterrestrische Physik (MPE) [12].…”

“…In 2017 we performed a first production run for second generation f=12 m middle radii mirror modules, to meet the requirement to supply 4 mirror modules [23] for the two parallel Assembly, Integration and Verification (AIT) activities [24,25] of ESA, another part of ESA's TDP plan, to develop methods to co-align and integrate mirror modules into the Athena optical bench. Such a production run allows testing all parts of the stacking chain, from plate inspection, cleaning to stacking on two different types of mandrels, using several stacking robot operators working in shifts, to x-ray testing them at XPBF 1 (X-ray pencil beam facility) [26,27] or the new XPBF 2.0 (X-ray parallel beam facility) [28,29], both operated by PTB at the BESSY II synchrotron radiation facility. As preparation for the production run we had in the first half of 2017 upgraded the stacking facilities, water supplies, control equipment and trained additional stacking robot operators.…”

Silicon Pore Optics (SPO) has been established as a new type of x-ray optics that enables future x-ray observatories such as Athena. SPO is being developed at cosine with the European Space Agency (ESA) and academic and industrial partners. The optics modules are lightweight, yet stiff, high-resolution x-ray optics, that shall allow missions to reach an unprecedentedly large effective area of several square meters, operating in the 0.2 to 12 keV band with an angular resolution better than 5 arc seconds. In this paper we are going to discuss the latest generation production facilities and we are going to present results of the production of mirror modules for a focal length of 12 m, including x-ray test results.

“…The mirror modules are characterised in two independent X-ray facilities, operated by two independent teams: the the Xray Parallel Beam Facility (XPBF 2.0) in the laboratory of the Physikalisch-Technische Bundesanstalt (PTB) at the BESSY II synchrotron radiation facility in Berlin, and the PANTER long beam facility of the Max-Planck-Institut für Extra-terrestrische Physik located near Munich [53][54][55][56][57]. The contiguous area fraction is defined as the fraction of the total MM optical face area, which extends over many plates of the MM, but is laterally limited by baffles.…”

“…Dedicated X-ray metrology, verification and calibration facilities are required for the assembly and characterisation of the mirror modules, and the verification and calibration of the complete ATHENA optics. Recently a new beamline (XPBF 2.0) was completed [56], where mirror modules of 12 m focal length can be assembled, using a collimated synchrotron radiation beam ( figure 12). This beamline is located in the laboratory of the Physikalisch-Technische Bundesanstalt (PTB) at the BESSY II facility in Berlin.…”

The development of the X-ray optics for ATHENA (Advanced Telescope for High ENergy Astrophysics)[1-4], the selected second large class mission in the ESA Science Programme, is progressing further, in parallel with the payload preparation and the system level studies. The optics technology is based on the Silicon Pore Optics (SPO) [5-48], which utilises the excellent material properties of Silicon and benefits from the extensive investments made in the semiconductor industry. With its pore geometry the SPO is intrinsically very robust and permits the use of very thin mirrors while achieving good angular resolution. In consequence, the specific mass of the resultant ATHENA optics is very low compared to other technologies, and suitable to cope with the imposed environmental requirements. Further technology developments preparing the ATHENA optics are ongoing, addressing additive manufacturing of the telescope structure, the integration and alignment of the mirror assembly, numerical simulators, coating optimisations, metrology, test facilities, studies of proton reflections and meteorite impacts, etc. A detailed Technology Development Plan was elaborated and is regularly being updated, reflecting the progress and the mission evolution. The required series production and integration of the many hundred mirror modules constituting the ATHENA telescope optics is an important consideration and a leading element in the technology development. The developments are guided by ESA, implemented in industry and supported by research institutions. The many ongoing SPO technology development activities aim at demonstrating the readiness of the optics technology at the review deciding the adoption of ATHENA onto the ESA Science flight programme, currently expected for 2021. Technology readiness levels of 5/6 have to be demonstrated for all critical elements, but also the compliance to cost and schedule constraints for the mission.
