Special Brazed Assemblies

The electron collector is a component of an ion source and ensures the separation of released electrons and an ion beam. It is made of stainless steel, aluminium oxide and copper. Its interior surface is highly polished. The cylindricity is < 0.05 mm on the bore Ø 0.9 mm (beam guide). With regard to the leakage rate, we achieve a value of < 1×10-¹⁰ mbar x l/sec.

The sputter head developed by REUTER TECHNOLOGIE consists of a layer of strongly ferromagnetic steel and two further layers of copper and boron nitride (BN). The place of use is a PVD coating plant. Here it serves as a holder for rectangular targets. It has to withstand high and homogeneous magnetic flux densities of up to 44 µ Tesla, provide efficient cooling of up to 2 kilowatts, and handle shielding and high-voltage feedthrough.

The GPU from REUTER TECHNOLOGIE ensures a supply of fuel in fuel cells. In it, catalysts are used to convert propane gas, for example, directly into usable hydrogen gas. We use various joining technologies such as vacuum brazing as well as laser and TIG welding in the production process. In vacuum brazing, several special stainless steels such as CroFer or Inconel and over 50 sheets are brazed simultaneously in one process step.

Sample tubes are used for material investigations in the cryogenic range. They consist of thin-walled tubes with wall thicknesses of only 0.3 mm. The length is up to 1000 mm. We typically manufacture our sample tubes in the material combination stainless steel and copper. The components included are joined in a vacuum-tight manner by high-temperature brazing and welded in a laser or TIG process.
