Abstract
The exemplary embodiments produce successive x-ray beams with different wavelengths and may comprise a rotating anode whose anode body has x-ray generating parts of different materials. Heretofore, the x-rays arising at the parts have been conducted through filters outside the tube which, synchronously moved, are allocated to the parts of the rotating anode. Since, however, the allocation of the filters to the parts of the anode is difficult in such a subsequent synchronization, according to the disclosure a fixed allocation ensues in that the filters are incorporated into the tube and are integrated in the rotation of the anode. To that end, they are designed as walls lying at right angles in the discharge path of the x-rays and are rigidly connected to the shaft of the anode arrangement. Such x-ray tubes are particularly suitable as a radiation source for employment in medical x-ray diagnostics.
