Vacuum brazed assemblies for basic research and industry
In research centres such as CERN, GSI or SLAC, particle accelerators help to learn more about the basics and constituents of the universe. Final pressures down to < 1·10-10 mbar, outgassing rates below 5·10-10 mbar·ls-1·cm-2, maximum leakage rates of 1·10-10; mbar·l·s-1 the dimensional accuracy of all vacuum components as well as the virtually particle-free surface are the key data for this application. With the development and manufacture of low-temperature collimator systems, ion sources, thermal chambers, storage rings, butterfly valves and various welded parts, REUTER TECHNOLOGIE has already been able to design and produce a large number of different components for this high-technology sector.
Product example: Low-temperature collimator system, operating temperature 4K

Electron storage rings, such as ESRF, HASYLAB, DIAMOND or BESSY accelerate electrons (or positrons) in synchotrons close to the speed of light. After that, they are injected into the circular storage ring. Suitable dipole magnets hold the electrons on their circular path and emit high-quality light at the deviation point. This synchrotron radiation is processed in the connected beam lines using monochromators and mirrors to enable tests in the vacuum at the experiment stations. In addition to this classic dipole radiation, undulators and wigglers likewise generate synchrotron radiation in the straight sections of the storage ring. Further developed versions of the storage rings with a strongly improved brilliance are the free electron lasers such as XFEL, FLASH or FERMI.
