Neutron Guide Alignment

IMG_9751
3D CMS S-DH ++

The alignment of the neutron guides is based on our coordinate measuring machine (CMM). Each guide unit is measured on the Renishaw CMM in house and aligned with the laser tracker Leica 406, a total stations Leica T5000 and two theodolites on site.

We measure the front and back face of the guide units with respect to an additional measuring feature.

alignment plate for the extensions

The Extensions: The alignment plates are made of glass. They have a bore, a groove and a plane.

Extensions from a Chopper guide

The Extensions, the best solution. It consists of two parts: alignment plate and extension. The plates are glued onto the units and the extension stands on top of the plates.

Extensions on a chopper guide

The extensions have three ceramic spheres, which fits perfectly to the alignment plates. The repeatable accuracy is 5 microns.

Extensions at work

On site, the extensions allow for very quick and precise alignment.
