Metallic Neutron Guides

Neutron guides usually are made of glass. Thanks to its amorphous structure, glass can be polished more easily than other materials. But glass is fragile and the lifetime under high radiation is limited. Our solution: metallic substrates. We manufacture neutron guides made of aluminium, copper and AluBor.
The new material AluBor was developed in close collaboration with the Institut Laue-Langevin in Grenoble.

In the year 2015 we invented the free standing, self evacuated, metallic neutron guide. It can be directly pumped and don't need an additional vacuum housing. We advise against doing it with glass, with aluminium and Alubor, it is possible.

Aluminium: we are able to polish aluminium in the same quality as glass.


Copper is planned to use for the In-monolith parts at the ESS. For test purpose we manufactured a guide unit with m=2.5 coating. Our supermirrors on copper shows the same performance as on glass.

Borated Aluminium neutron guide

Borated Aluminium: Our AluBor.

It combines the best of two worlds: the good access and no additional vacuum housing from the open system and the stability and security of the closed system.

Free standing, self evacuated neutron guide. An advanced sealing technique guarantee vacuum tightness. We produce directly pumped neutron guides from aluminium and Alubor substrates.
