Abstract
Nanometer scale structures such as multilayers, gratings and
natural crystals are playing an increasing role in spectroscopic applications
for X-ray astrophysics. A few examples are briefly described as an introduction
to current and planned applications pursued at the Danish Space Research
Institute in collaboration with the FOM Institute for Plasma Physics,
Nieuwegein, the Max-Planck-Institut für Extraterrestrische Physik,
Aussenstelle Berlin, the Space Research Institute, Russian Academy of Sciences,
the Smithsonian Astrophysical Observatory, Ovonics Synthetic Materials Company
and Lawrence Livermore National Laboratory. These examples include : 1. the
application of multilayered Si crystals for simultaneous spectroscopy in two
energy bands one centred around the SK-emission near 2.45 keV and the other
below the CK absorption edge at 0.284 keV; 2. the use of in-depth graded period
multilayer structures for broad band spectroscopy in the energy range up to
100 keV; 3. the potential use of large perfect asymmetrically cut Si or Ge
crystals combined with a short focal length multilayer telescope for ultra high
energy resolution solar/stellar spectroscopy with
and; 4.
high throughput multilayer coated telescope for high resolution Fe K line
spectroscopy with microcalorimeters.
