Different instruments devoted to solar physics are required to have high reflecting MultiLayers (MLs) coatings. For example, the Multi Element Telescope for Imaging and Spectroscopy (METIS) coronograph will fly on board of SOLar Orbiter (SOLO) mission to perform simultaneous observation at 30.4 nm (He - II Lyman - α line), 121.6 nm (H - I Lyman - α line) and in the visible range, therefore its optics will require high performances in a wide spectral region. It should be desirable to reach higher reflectivity as well as long term stability and lifetime, then different candidate coatings will be considered. The Sounding - Rocket Coronographic Experiment (SCORE) is a prototype of METIS equipped with Mg/SiC optics and it has flown on board of a NASA sounding rocket. The Mg/SiC multilayers offer good performances in term...

Whatever the application and the engineering purpose, a fine control of the chemical and physical properties is required since the performances of graphene based systems depend on the reduction state of Graphene Oxide and can be strongly affected by interfaces interactions and neighboring effects. Then, a method for a local control of electric, electronic and chemical properties is required. The synergic application of Near Edge X ray Absorption Fine Structure Spectroscopy and Conductive Atomic Force Microscopy is a powerful way for such purpose allowing a full characterization of simple and composite samples, including specimens with dielectric discontinuities. Graphene Oxide/Gold (GO/Au) and Graphene Oxide/Silicon Oxide (GO/SiO2) have been selected as proof by example. The results show that the a...

As a part of the payload, the instrument METIS (Multi Element Telescope for Imaging and Spectroscopy) will provide images of the corona, both in the visible range and at the hydrogen Lyman-α emission line (121.6 nm). The realization of optical coatings, based on Al and MgF2, able to reflect/transmit such spectral component is therefore necessary. Since optical characteristics of materials in the VUV range are not well studied and greatly varying with realization process, we implemented a study of their properties in different deposition conditions. This is aimed to the realization of a custom designed filter, able to transmit the 121.6 nm while reflecting the visible light, and thus separate visible from UV light paths in the METIS instrument.

Laser wavelength and pulse duration were of 46.9 nm and 1.7 ns, respectively. The laser beam was focused onto the sample surface by a spherical Sc/Si multilayer

Calibration of QM and FM instrument are on going. An approach based on the Mueller Matrix formalism is adopted to determine the pure efficiency of the instrument (PHEBUS). The results obtained show that this approach is a complete and versatile method to perform the radiometric calibration of a space instrument.

Optical coatings with high reflectance performances at the interested wavelengths are required to collect enough light at the detector level. Different multilayer structures based on Si/Mo couples with appropriate capping layers have been already designed and tested to achieve this purpose. A model has been developed in order to estimate the efficiency's performances of the instrument on the whole field of view (FoV) by considering the ray paths. The results shown have been obtained taking into account of the experimental results on multilayers structures previously tested and the optical design of the instrument.

We have built a new cleanroom environment, divided in different areas characterized by a different level of contamination control. A vacuum chamber (a tube of 80 cm diameter, and 2 m length), able to accommodate optical components as well as whole instruments, is interfaced with a ISO6 area, allowing the handling of the instrumentation in a clean environment. The vacuum system is dimensioned to reach 10-7 mbar pressure in the chamber. Inside, a two axis platform allows the rotation of the instrument with respect to the incident collimating beam, in order to test the response of the instrument to light coming from different points of the field of view. A monochromator coupled with different sources provides radiation in the 40-350 nm spectral range, while a parabolic mirror is used as a collimator. As source, different spectral lamps can be used to generate emission lines, while a Xe lamp can be used to have continuum spectrum. An high brilliant hollow cathode lamp has been fabricated by the group to generate extreme ultraviolet radiation. Different calibrated detectors and other completing optical components are available.

It will investigate the composition and dynamic of Mercury's exosphere to better understand the coupled surface -exosphere -magnetosphere system of the planet. The radiometric calibration tests are ongoing and an approach based on the Mueller Matrix formalism has been adopted to determine the pure efficiency of the instrument. To our knowledge, this is the first time that a such complete method is applied to the calibration of space instrumentation.

Novel materials couples have been recently considered to improve the efficiency performances in different spectral regions. The deposition of capping layer structures onto standard periodic Mo/Si multilayers is used to add specific properties, such as high resistance to aging and different damage processes, or to regulate the reflectance in other spectral regions. This solution is adopted in the development of multilayer to be used in FERMI@ELETTRA FEL beam transport systems for third harmonics selection.
