A recent and considerable milestone for the ESS Target Division was the delivery of the twister shaft from its German manufacturer, Saarschmiede. Designed by in-kind partner Forschungszentrum Jülich (FZJ), the five-metre-long, 6050-kilogram steel component shields cold and thermal neutrons, and acts as a support for piping, the beryllium reflector, and the moderator. The twister shaft was developed to allow replacement of moderator and reflector components as required without dismantling the target wheel. It sits parallel to ESS Bilbao’s six-metre-long main target wheel shaft.
