Our department is located on the third floor of the Institute of Inorganic Chemistry, part of the Georg-August-University in Göttingen. The photo shows the institute building, located in between the Institutes of Physical and Organic Chemistry (to the left and right, respectively). The northern university campus is the location of several faculties of natural sciences.
X-Ray Facilities
As external X-Ray source for macromolecular data collections at higher resolution and/or in case of smaller crystals, we generally use the EMBL beamlines at the DESY synchrotron in Hamburg. For screening of macromolecular crystals and collection of derivative or native anomalous data for phasing, there are two rotating anodes with focussing optics and modern area detectors in our laboratory. All our beamlines are equipped with low-temperature devices.

We still determine small molecule structures, and indeed every new Diploma student is expected to determine about ten small molecule structures before she or he is allowed to start on a macromolecular structure: this has many didactic and psychological advantages. For the small molecule work we have access to two area detector systems with MoKa radiation. Of particular historical interest is 'Quatermas', one of the first CCD systems used in an X-ray lab.

Quatermas was one of the first science fiction programs to be shown on television in the UK (in the early 1950's). For reasons that will be clear to those who are old enough to remember the program, Quatermas is an appropriate description of a machine put together from pieces from several different manufacturers, as well as sounding like a four-circle.

Quatermas (donated to the Dept. of Physics, University of Ulanbaatar, Mongolia) consists of Huber offset chi and phi circles, Stoe X-ray optics, omega and 2-theta circles, Bruker (nee Siemens) sealed tube (Mo) generator and CCD-detector, and home-made low-temperature attachment and X-ray safety enclosure that also serves as a dry-box. A video-CCD camera (not shown) is used to center the crystal, and the goniometer head is heated ensuring completely ice-free operation.

How to reach us ...
Göttingen is a city of about 130,000 inhabitants close to the geographical centre of Germany. For those arriving from abroad, Göttingen can be reached in two hours by ICE train from Frankfurt airport. The smaller and closer Hannover airport is an alternative for European flights.
The natural sciences campus is located to the northeast of Göttingen. Coming from the motorway by car, it is reached very straight-forward. Taking a taxi from the station, you will reach our institute within 10 minutes.
