Settore FIS/05 - Astronomia E AstrofisicaX-ray detectors for astrophysics optical blocking filters CNT synchrotron absorption spectroscopy X-ray photoelectron spectroscopy mechanical testsdescription
In this paper, we present the first results from an investigation performed on nanometric thin pellicles based on carbon nanotubes (CNT) of potential interest for manufacturing large area optical blocking filters to protect soft X-ray detectors in astrophysics space missions. In order to evaluate the effective capability of such materials to block UV/VIS/IR radiation, while being highly transparent in the soft X-rays and strong enough to withstand the severe launch stresses, we have performed a suite of characterization measurements. These include: UV/VIS/IR and X-ray absorption spectroscopy, X-ray Photoelectron Spectroscopy and Scanning Electron Microscopy on bare and Al coated small self-standing pellicles; static mechanical tests on small freestanding samples.
