THE X-RAY-FLUORESCENCE MEASUREMENT PLACE AT BEAMLINE-L OF HASYLAB

The following article describes the experimental facility for synchrot ron radiation induced X-ray fluorescence analysis (SYXRF) at beamline L of the Hamburger synchrotron radiation laboratory (Hasylab) at the D eutsches Elektronen-Synchrotron (DESY) in Hamburg. At the facility sim ple bulk analysis (SYXRF), high spatial resoluting measurements (mu-SY XRF), total reflection experiments (TR-SYXRF), surface analysis by mea ns of grazing incidence (SY-GIXA) and analysis of crystallographic par ameters by means of Kossel diffraction are possible. A great variety o f excitation spectra can be chosen by absorbers, reflectors and a mono chromator. The beam size is defined either by cross slits or by a focu sing capillary. The measurements take place in air or helium atmospher e, and the fluorescence radiation is detected by either a Si(Li) or HP Ge detector depending on the energy range of interest. The major advan tages are an easy to handle control of the highly flexible setup, smal l beam sizes, and low detection limits.
