Abstract

The new Incoatec Microfocus Source IμS™ with molybdenum anode, a 30 W air cooled sealad tube microfocus X-ray source, with a new type of 2-dim beam shaping Montel optics, the so called Quazar™ optics, was mounted at a mar desktop beamline equipped with mar345 imaging plate detector (figure 1). This setup was used to investigate phase transitions of different samples under high pressure and high temperature. For this purpose a diamond anvil cell or a heater was mounted on the goniometer respectively.

To process the data precise information about the sample to detector distance and the detector orientation is necessary. To receive this information, measurements of the standard LaB6 were done under the same conditions as the measurements of the samples. The data were processed using the program package Powder3D (Dinnebier et al.) for integration and visualisation.
