Non-ambient Powder Diffractometer Legolas - X-ray center

Vienna University of Technology

Wien | Website

Large equipment

Short Description

The instrument in vertical theta/theta geometry is mainly used for crystallographic phase analysis of crystalline solid state materials at non-ambient conditions. By default the instrument is equipped with a Si-based position sensitive detector (PSD), PANalytical X'Celerator, and can be runned also with a point detector in combination with a graphite monochromator. Several sample environment devices can be provided: Anton Paar high temperature chamber up to 1200°C, inert gas atmosphere, vacuum (HTK 1200); Anton Paar reaction chamber up 900 °C and gas pressures up to 10 bar (HTK 900); Oxford He closed cycle cryostate down to 11 K.

Research Services

The X-ray center of the TU Wien (XRC) offers services for X-ray diffraction measurements, phase analysis and stress/texture analysis of crystalline materials mainly for institutes and employees of the TU Wien, respectively. Instituts outside the TU Wien can place an order for analysis within research cooperations with the XRC. On a limited scale also orders from a third part can be accepted.
