The four circle goniometer can be conveniently used for carrying out powder diffraction in ambient as well as in different sample environments, e.g. low and high temperature and high pressure. A cryostat for low temperature measurement is mounted on the goniometer. Samples can be in the form of powders or thin films/multilayers on solid substrates. An aluminized mylar window as the radiation shield and Be window for the vacuum shield is used in the cryostat. Typical scans are theta�2theta and sample temperature down to 10 deg K and in specific cases up to 4.2 deg K. The usable energy range of the synchrotron x-ray radiation is 7 to 20 keV. One can use either point detector (Cyberstar) or 100K 2D Pilatus detector for data collection.
