Abstract:
1. A method for spatially resolved measurement of parameters in a cross section of a beam bundle of high-energy radiation of high intensity in which beam components at a location of interest in the beam bundle are coupled out to a measuring device, comprising the following steps: shading the beam bundle through a shading element so that the cross section of the beam bundle is imaged on a shading element; coupling out partial beam bundles having a reduced cross section and reduced intensity in relation to the beam bundle by means of at least one opening in the shading element; successively separating the beam bundle in time into variously positioned partial beam bundles through movement of the at least one opening of the shading element to different positions within the cross section of the beam bundle to be measured by a movement of the shading element; successively acquiring measurement values of the partial beam bundles in time by a measuring device, the partial beam bundles being transmitted through the at least one opening, and acquiring an associated position of the partial beam bundles in the cross section of the beam bundle depending on a given path of the opening resulting from the movement of the shading element; and storing measurement data comprising measurement values and associated positions of the successively acquired partial beam bundles.
