"Thanks to the experience achieved in 2010 with ILL on the IN16B vacuum chamber,  we are now participating in other challenging projects, such as the construction of the PANTHER helium vessel with high internal precision requirements, or the WASP helium chamber with high-precision machining."

"We are pleased to have the ILL as one of our valued customers; our expertise in power supplies has enabled us to deliver a robust product that will serve the ILL for many more years of research."

Electrical power supplies for the WASP precession coils and inner compensation coils

Danfysik is proud to have been selected as the ILL's partner in the design and manufacturing of power supplies for the WASP main coils. Our well-proven switch mode power supply Model 859 was considered to be the best solution, since the precession coil required a massive 800A/500V 50ppm long-term-stability power supply, and the inner compensation coils required 480A/170V. 
After installation and commissioning, the ILL was happy to confirm the power supply's conformity with requirements.

In 2017 SwissNeutronics was awarded the contract to produce neutron guides for the refurbishment of the ILL H1-H2 guide system (in-pile “Pink Carter“ and swimming pool sections). The high-precision interface features are directly machined into the neutron guides, mading guide installation and alignment easier. The parallel guide units at the departure of the guide system were combined with precision to enable accurate alignment within a constrained environment. The figure below shows the two triple guide units for the in-pile section of the H1-H2 guide system (one system mirrored in the other).
