Bayerisches forschungsinstitut für experimentelle geochemie und geophysik


Principal characteristics of the facility and of the support offered to users
The Bayerisches Geoinstitut is a research institute dedicated to experimental investigations of the physical and chemical properties of materials at high pressures and temperatures. Although the main aim of the institute is to understand the composition, structure and dynamics of the Earth's interior, research directions overlap significantly with the fields of solid-state physics and chemistry and material science. The institute is equipped with a wide range of high-pressure apparatus for synthesis and in-situ studies and with a large variety of equipment for characterising the composition, structure and properties of materials, both in-situ at high pressure and temperature and at ambient conditions. The facilities include a high-pressure laboratory currently equipped with two multianvil presses (25 GPa, 3000 K), which is unique in Europe (a third multianvil press will be installed during 1997). The diamond anvil cell facilities, which in total are unique world-wide, offer a broad range of techniques including single-crystal X-ray diffraction, in-situ spectroscopy (infra-red, Raman, optical absorption and Mossbauer) and in-situ ultrasonics (gigahertz interferometry). Other facilities include piston-cylinder and hydrothermal high-pressure laboratories, calorimeters, NMR, analytical transmission electron microscope, electron microprobe, ultrasonic interferometers and electrical impedance analyser. Although users will have access to all experimental facilities, interest is centred on the multianvil and diamond anvil cell laboratories because of their uniqueness in Europe. Users will receive full scientific and technical support from institute staff in these and other laboratories in terms of training and becoming able to independently perform experiments on an equal basis with internal users.
Quantity of access being offered and number of users who may benefit: The access offered consists of 1140 experiment days over a period of three years. Based on current interest, approximately 34 user groups involving around 50 individual researchers will benefit. The user groups include some which already have access under the current HCM contract and at least 15 new user groups.
