Plasma and fusion research

Plasma and fusion research depends on high cooling capacity at very low temperatures and therefore requires large cooling systems. In addition to the large cryogenic power required for the superconducting magnets, this power is also of great importance for the cooled radiation shielding, cryogenic pumping systems and test benches.

Liquid helium is usually used as a cooling medium at temperatures just above absolute zero around -271 °C. Greatest attention is being paid to achieve lowest heat loss. For this very reason WEKA has developed and manufactured solutions for these demands. They have been used in research for many years.​

Cooling of superconducting magnets and the accelerating cavities is an important impulse for the production of cryogenic equipment and distribution systems.

The cold fluid has to be distributed efficiently over the whole area of the experiment, so that the cooling takes place where it is needed. The fluids flow is supervised by means of control and shut-off valves. In addition to the process parameters, there are often other boundary conditions, such as magnetic fields or neutron radiation, which must be taken into account when designing the valves.

Our control and shut-off valves are available with either pneumatic, electric or manual actuators. Check valves, safety valves, transfer line couplings and ejectors are also part of our wide range of technologies for this area.
