Abstract:
1. A method of operating a configuration for producing electro-magnetic radiation, which comprises: directing particles onto a target by way of an adjustable focusing device, for producing electromagnetic radiation in the target; placing a measurement object in a beam path of the electromagnetic radiation, and radiating the electromagnetic radiation through a measurement object; providing a calibration object and movable mount for moving the calibration object; for adjusting the focusing device, temporarily introducing the calibration object into a predetermined position relative to the target and in the beam path of the electromagnetic radiation by way of the movable mount, in addition to the measurement object and without removing the measurement object from the beam path, recording a radiograph of the object or recording a plurality of radiographs and subsequently removing the calibration object from the beam path by actuation of the mount; automatically evaluating the radiograph or the plurality of radiographs; and adjusting the focusing device in dependence on the evaluation obtained in the evaluating step.
