Description

Currently the international accelerator facility FAIR, one of the largest research projects worldwide, is being built in Darmstadt, Germany. At FAIR, matter that usually only exists in the depth of space will be produced in a lab for research. Scientists from all over the world will be able to gain new insights into the structure of matter and the evolution of the universe from the Big Bang to the present. The tender relates to the following procurement. The polished plates are part of the pillow seal system which is used to connect the vacuum chambers along the Super-FRS. They are mounted on the vacuum chamber site to interact as the surface to which the pillow seals are pressed. In total there are 16 polished plates needed in the Super-FRS. Polished vacuum sealing plates 16 plates flat and well polished made of stainless steel shall be built. There are variations in shape, round ones with outer diameter of 730 mm and racetrack shape with length of 1430 mm. In the middle there is an opening for the free aperture of the beam pipe system. The plates are intended for the Super-FRS in the new accelerator facility FAIR under construction in Darmstadt, Germany. Pillow-seals with inflatable metal foils are a way to avoid bolting in dangerous areas and themselves they are radiation hard. As counterparts they require the polished plates in this tender. Different to a normal vacuum seals here not only a groove has to machined for sealing but a larger surface. On the backside these plates are equipped for normal sealing systems like CF or other metal gaskets for the larger ones. The plates will be bolted to vacuum chambers in the Super-FRS beamline. Schematic drawings of the sizes and required surfaces exist, detailed manufacturing drawings have to be made.
