Tender Details

Standard Beam-Vacuum Cold-Warm Transitions - SIS100 With the FAIR project (Facility for Antiproton and Ion Research), one of the most modern particle accelerator and experimental facilities in the world is currently being built at the GSI site in Darmstadt. The one under The facility complex, developed and financed with international participation, is used for basic scientific research and experiments in numerous applied scientific disciplines. The responsibility for the realization of the system was taken over in the year FAIR GmbH, founded in 2010. The GSI Helmholtz Center for Heavy Ion Research takes on numerous administrative-technical tasks, including certain procurement processes, within the framework of contractual agreements with FAIR GmbH. For the The main accelerator of the FAIR facility, the heavy ion synchrotron SIS100, requires so-called cold-warm transitions. These are UHV vacuum chambers that contain beam pipe sections of the accelerator ring in the room temperature ranges Connect jet tube sections that operate at liquid helium temperatures. These cold-warm transitions are equipped with two corrugated bellows, have a large cryostat connection flange and provide the connection via CF flanges between the cold and warm jet pipes. At the same time, the assemblies serve to compensate for changes in length and distance that occur as a result of the cooling and reheating of the cold radiant pipe areas and their...
