The cooling disc is part of a dilution cryostat in an accelerator. Water flows through the cooling disc interior as one of various high-efficiency heat exchangers. In addition to the design and manufacture of all components, the special challenge of this component was the assembly, solder application and vacuum-brazing of more than 100 components in
one single process step.


The vacuum-brazed copper / stainless steel structure of this sophisticated waveguide serves for the transfer of high energies. As the electric field strengths are extremely high at such power levels, geometrical irregularities may cause the destruction of the component. This is one of the reasons why a highly precise surface finish must be ensured during manufacture and vacuum-brazing.

Precision in copper –  for tomorrow’s technologies!

Some of the most exciting scientific projects of our time require a very high accuracy and a precision that appeared unfeasible just a few years ago. In mechanical machining and joining technology, the requirements for tolerances and characteristics have increased to the limits of what is technically possible. The represented copper structures of sophisticated waveguides are intended to transfer very high energies in particle accelerators. As the electrical field strengths are extremely high at such power levels, deviations within the waveguide structures might lead to increased field intensities and, with this, to flashovers and ultimately to the destruction of the component. Therefore, an extremely precise execution of the freeform surfaces and surface finishes has to be ensured during manufacture and vacuum brazing.


Roughness depth up to 25 nm without any post-machining!

The shape tolerances for freeform surfaces of 0.02 mm in combination with a mean roughness depth Ra of 0.1
0,1 µm (partly up to 25 nm) are required to meet the requirements of radio frequency and beam dynamics. No deviations are permitted.

In most cases, this precision must be achieved directly on the processing machine, without the possibility of manual reworking such as grinding, lapping or polishing. This also applies to those joining technologies that likewise have to meet extraordinarily high requirements. The brazing alloy applied on single components (gold alloy) must be so exact that no brazing alloy protrusion is possible after brazing. Otherwise, the waveguide structure is damaged and the component becomes unusable.

During and after manufacture, the generated dimensions are verified with the aid of a 3D measuring machine and in a roughness measurement and documented in detail.
