Abstract: The invention relates to a method for operating a computed tomography device (150), wherein the computed tomography device (150) comprises at least one x-ray radiation source (131) configured for generating x-ray radiation cones (132) for irradiating an object (134), wherein the computed tomography device (150) comprises at least one detector (136) configured for detecting the x-ray radiation of the x-ray radiation cones (132) that have interacted with the object (134), wherein the x-ray radiation source (131) comprises at least one electron optic arrangement (138) configured for variably arranging at least one electron beam (140) onto a plurality of positions of focal spots on at least one target comprised by the x-ray radiation source (131) in a manner that a plurality of different x-ray radiation cones (132) emerging from the focal spots is generated in order to image different portions of the object (134); the method comprising: performing a projection image scanning sequence (PSS) by using an imaging

Abstract: A sample changer for an X-ray analysis device comprises a tray rotatable around a rotation axis Y and having a plurality of sample positions in a circular pattern, the tray being driven by a motor. The sample changer comprises a telescopic arm having a drive system designed to perform a linear translatory back and forth movement in a Z-direction perpendicular to the rotation axis Y with a gripper arranged on the telescopic arm designed to pick a sample from the tray and to carry the sample to a measurement chamber in the X-ray device and back. The telescopic arm is arranged in an XZ plane perpendicular to the rotation axis Y and is radially directed from the center to an outer circumference of the tray. This mechanism allows pre-selecting and positioning the samples next to a loading opening in order to facilitate a less time-consuming measurement.
