Its success is inextricably linked with the use of large-scale equipment at national and international research centres. "With the new concept, basic research in Germany will start from an excellent position when entering a new decade of successful work", Minister Bulmahn said. Together with European partners, the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt is to develop further its equipment in a phased approach and become a leading european physics centre. At least 25% of the costs amounting to €675 million are to be shouldered by foreign partners.
