Abstract

A diffraction apparatus (10) for determining crystalline and polycrystalline materials of an item in objects, preferably in luggage, having a collimation/detector arrangement (11) and an X-ray source (12) and which is mounted to be adjustable in an X-ray testing machine (13). The collimation/detector arrangement (13) is adjustable in height relative to the X-ray source (12), and the two are also laterally and synchronously adjustable via respective adjustment elements (5,6). The collimator (13) has a conically-expanding round slot (15), which simulates a predetermined angle (&THgr;M) of a scatter-beam path.
