We built a quadruple reflection polarizer which can be used in the energy range hν=8–130 eV to convert linearly polarized synchrotron radiation into circularly polarized light of either left or right handedness. The design permits independent adju

The High Energy Transmission Grating Spectrometer of the Chandra X-Ray Observatory is a high spectral resolution instrument utilizing gold X-ray transmission gratings. The gratings have been subjected to a rigorous program of calibration, including t

We have developed optical filters for ESA's x-ray astronomy project XMM (x-ray multi mirror mission). Specific CCDs will be used as detectors in the focal plane on board the observatory. Since these detectors are sensitive from the x- ray to the NIR

We report about the diffraction efficiencies of two new types of multilayer diffraction gratings, one of them being proposed for high spectral dispersion ability due to a high line density in the photon energy range around 90 eV, while the other is b

Soft x-ray detectors for astronomical applications are often also sensitive to visible and UV photons. Filters of a new design have been developed, which could be used in future missions to suppress the flooding of x-ray detectors by low energy photo

In order to characterize the instrumentation on AXAF, each of the science instrument teams carries out sub-assembly calibrations. For the high energy transmission grating (HETG) group, this means individual measurements of the diffraction efficiencie

C/Ti multilayers with a period thickness of 2.1-2.7 nm were produced by electron-beam evaporation in ultrahigh vacuum as soft-x-ray mirrors in the water window (lambda = 2.3-4.4 nm). For smoothing the individual interfaces and thus enhancing the tota
