    This thesis describes the research and development of STJs based on Nb/Al technology for application as X-ray detectors in astrophysics conducted by the Low Temperature division of the University of Twente in collaboration with the Stichting Ruimteonderzoek Nederland (SRON). Three topics have been investigated: the spatial inhomogeneous response of STJs which presently limits their performance, the introduction of a thick X-ray absorbing Nb single crystal into the detector design in order to enhance the photon detection efficiency and finally the suitability of Double Relaxation Oscillation Superconducting Quantum Interference Devices (DROSs) as readout amplifiers for cryogenic detectors.
