Abstract

We describe the principles of operation of the STJ spectrometer baselined for XEUS (X-ray Evolving Universe Spectroscopy mission), and describe some of the practical implementation issues that are being developed or trade-offs that are still being studied actively. The instrument is to be optimized for good energy resolution (<2eV FWHM) in the energy range between 0.1 - 3keV. The field of view should be maximized to allow spectroscopic mapping of modestly extended objects (e.g. cluster cores) and to maximize the number of point source objects analysed. This remains the greatest challenge for the instrument design.
