Abstract
At the radiometry laboratory of the Physikalisch-Technische Bundesanstalt a reflectometer for the soft x-ray spectral region is operated for several years utilizing monochromatic radiation from a toroidal grating monochromator or from a high resolution plane grating monochromator. The monochromators cover the photon energy region from 35 eV to 1500 eV. New challenges due to the development of soft x-ray optical components led to the design of a second reflectometer with advanced capabilities. Samples with a diameter of up to 250 mm can be accommodated. The time required for sample exchange is reduced by using a lock chamber. The feasibility of sample positioning with high precision has been improved. Typical uncertainties in the order of 1 - 2%, e.g. for the reflectance of multilayer mirrors, can be achieved. A detailed description of the reflectometer as well as some typical results showing the performance are presented.
