Arrangement for the examination of a body with a radiation source

摘要

The invention relates to an arrangement for the examination of a body with a radiation source for the generation of a primary beam of small cross-section, having means to generate a relative displacement between the body on the one hand and the primary beam on the other hand, having a detector arrangement detecting the radiation scattered elastically at small scattering angles and with means for the detection of the scattering angle and, if necessary, the pulse transmission. In this case, a spatial resolution in the direction of the primary beam can be achieved by arranging a plurality of diaphragm leaves between the body and the detector arrangement so that scattered radiation from different sections of the primary beam falls in each case on various strips on the surface of the detector arrangement, and so that the detector arrangement has a lateral resolution capability in the longitudinal direction of the strips. <IMAGE>
