The first experimental hutch of P09 (EH1) is equipped with a highly flexible and precise Psi-diffractometer with open Chi-circle. At the sample position, a simple goniometer mount, Displex cryostats or other small sample environments (<15 kg), like ovens or electromagnets, can be mounted on the motorized xyz-translation stage. The detector arm consists of two translations separated by 25 degrees. One is used for the setup with polarization analyzer and point detector, whereas the other is used with an area detector. Currently, here a Pilatus 300k detector is installed. A silicon drift detector can be used for fluorescence measurements mounted from the side. Various analyzer crystals are available to be used as with the polarization analyzer. All edges between 2.8 keV and 15 keV are covered.
