The requirement that the analyser was to be mounted on a diffractometer meant the construction needed to be as lightweight and as compact as possible. This provided opportunities to explore new collaborative ways of working with both in-house and external suppliers. The paper describes the approach taken to develop lightweight aluminium vacuum chambers working with a company specialising in additive layer manufacturing. In addition, the design of lightweight and compact slit assemblies are detailed; these were developed in collaboration with a supplier of driven linear stages. A novel requirement for the analyser is to have a detector mounted on a rotation axis in vacuum. The results of working with the in-house detector group to develop a design to with all the necessary thermal and electrical connections are described. The paper also describes further use of additive layer manufacturing to produce prototypes that allows the design of a cable management system to be optimised where previously using 3d CAD models had proved unsatisfactory.
