| Zusammenfassung | We present an experimental study of the performance of Distributed Read-Out Imaging Devices (DROIDs), 1- and 2-dimensional photon-counting imaging spectrometers, based on Ta/Al-based STJs placed on a Ta absorber. Results obtained with highly collimated illumination with 10 keV X-ray photons clearly demonstrate the imaging capabilities of 2-dimensional DROIDs. The derived spatial FWHM resolution is 7 µm for a 200 × 200 μm² absorber. With a 1-D DROID we have measured an intrinsic energy resolution of 15 eV FWHM for 6 keV photons. At high energies (E ) 6 keV) the resolution is limited by spatial fluctuations in the qp recombination rate. |
