Abstract: X-ray system for examining N objects, in particular N battery modules for quality testing, comprising: a linear accelerator configured to emit X-ray radiation with an energy ?1 MeV at a cone-shaped emission angle; N X-ray detectors that are each configured to detect the X-ray radiation in a partial cone of the cone-shaped emission angle; N rotational axes and for N objects that are each assigned to a partial cone and that are arranged in each one; a collimator configured in two stages, wherein a first stage defines the cone-shaped emission angle at which the X-ray radiation is emitted and wherein a second stage defines the N partial cones.
