ORION: Alignment of crystals - A guide for triple axis users
These pdf-files contain a commandlist and a short guide to align a crystal on ORION.
The main difference to a triple axis instrument is, that ORION has a closed Eulerian cradle instead of two crossed (90deg) goniometer tables. The advantage of the Eulerian cradle used on ORION is, that the sample can be turned by a full circle (360 deg) around the support axis, allowing to drive almost any axis to a bisecting position. A a consequence, a limited omega range is no disadvantage.
