“…NiCo has better stiffness and microyield properties than Ni, therefore providing shells with a better image quality for the same thickness. This alloy was developed in the study of Simbol-X [7] and now of NHXM [8] . The effective area and the angular resolution are reported in Fig.…”

The Energetic X-ray Imaging Survey Telescope (EXIST) will continuously survey the full sky in scanning mode for 2-years followed by a 3-years pointing phase. The mission includes three instruments: a High Energy coded mask Telescope; a 1.1m aperture optical-IR Telescope; and a Soft X-ray Imager (SXI), sensitive in the 0.1-10 keV band. SXI is proposed as a contribution of ASI-Italy, fully developed by Italian institutes. Here we will present the optical and mechanical design of the SXI mirror module, that includes also a pre-collimator and a magnetic diverter to ensure a low background on the detector. In particular we will describe the mirror module characteristics in term of effective area, imaging capability, thermal requirement and mechanical properties. The current optical design foresees 26 shells providing an effective area comparable to one XMM-Newton mirror module up to 3 keV. The realization of these shells is based on the well-proven Nickel replication-process technology.

Focusing mirrors manufactured via galvanic replication process from negative shape mandrels is the candidate solution for some of next future X-ray missions. Media Lario Technologies (MLT) is the industrial enabler developing, in collaboration with Brera Astronomical Observatory (INAF/OAB), the Optical Payload for future Hard X-ray mission. Concerning mandrel technology, MLT is engaged in a development programme aiming at improving the mandrels performance and their production rate. The angular resolution and the reflectivity of the mirrors replicated from the mandrels are strongly dependent on the mandrel performances and their stability. High throughput X-ray missions, require the massive production of mandrels in a short time, with angular resolution better than 7 arcsec Half Energy Width (HEW) and a surface micro-roughness in the order of 0.3 nm RMS. In order to achieve these results, several technological aspects are under investigation using a proprietary multistep surface finishing process. In particular, the metrology and the estimated optical performances of the mandrel are computed by means of dedicated post-processing and herein reported. Microroughness, medium scale errors, azimuthal slope error, axial slope errors, and mechanical dimensions are the quantities that have been measured by using atomic force microscope, high resolution optical profiler, contactless rotondimeter and high accuracy axial profilometer.

High throughput lightweight Hard X-ray Optics manufactured via electroforming replication process from supersmooth mandrels are the primary candidate for some of future New Hard X-ray missions. Media Lario Technologies (MLT) is the industrial enabler exploiting the electroforming technology initially applied for the ESA XMM-Newton mission and further developed in cooperation with Brera Astronomical Observatory (INAF/OAB). The current and ongoing development activities in Media Lario Technologies complement the electroforming technology with a suite of critical manufacturing and assembly of the Mirror Module Unit. In this paper, the progress on mandrels manufacturing, mirror shell replication, multilayer coating deposition, mirror module integration, and relevant metrology is reported in view of the upcoming production phase. Mandrel production is a key point in terms of performances and schedule; the results from of NiP prototype mandrels fabricated using a proprietary multistep surface finishing process are reported. The progress in the replication of ultrathin Nickel and Nickel-Cobalt substrates gold coated mirror shells is reported together with the results of MLT Magnetron Sputtering multilayer coating technology for the hard x-ray waveband and its application to W/Si. Due to the criticality of low thickness mirror handling, the integration concept has been refined and tested on prototype mechanical structures under full illumination UV vertical optical bench.
