Upgrading of the PETRA-2 beamline at HASYLAB for materials science analyses

The high energy synchrotron radiation beamline PETRA-2 at HASYLAB has been extended by two 2D-position sensitive multi-wire Xe/CO2 detectors with an active area of (300 mm)(2) and a detection probability of similar to 10% for 100 keV photons. The detectors may be placed at distances between similar to 1 m and 8 m from the sample in order to cover large space angles or to measure with high resolution, respectively. Fast 3D-data acquisition systems allow for analyses of continuous processes with excellent time resolution and sample movements during measurements with continuously operating detectors. The experimental set up will be especially used for analyses of residual stresses, local textures and kinetics of phase transformations. (C) 2001 Elsevier Science B.V. All rights reserved.
