    Abstract: Multi-energy radiation sources comprising charged particle accelerators driven by power generators providing different RF powers to the accelerator, capable of interlaced operation, are disclosed. Automatic frequency control techniques are provided to match the frequency of RF power provided to the accelerator with the accelerator resonance frequency. In one example where the power generator is a mechanically tunable magnetron, an automatic frequency controller is provided to match the frequency of RF power pulses at one power to the accelerator resonance frequency when those RF power pulses are provided, and the magnetron is operated such that frequency shift in the magnetron at the other power at least partially matches the resonance frequency shift in the accelerator when those RF power pulses are provided. In other examples, when the power generator is a klystron or electrically tunable magnetron, separate automatic frequency controllers are provided for each RF power pulse. Methods and systems are disclosed.

    Abstract: The invention relates to an X-ray tube, especially a microfocus X-ray tube (2), comprising means (18) for orienting an electron beam (10) towards a target (4). A control device (20) is used to control the means for orienting the electron beam (10) towards the target (4) in such a way that the electron beam (10) scans the target (4), in addition to a measuring device (22) for measuring the intensity of the target current which flows to different scanning sites when the target (4) is scanned by the electron beam (10), or a measuring variable dependent on the target current, and an evaluation device (24) for associating each measured value of the target flow with the corresponding scanning site. Said X-ray tube enables the easy and economical implementation of a method for checking the operability of the target (4).

    Abstract: A method for obtaining a concentrated, monochromatic x-ray beam from a standard x-ray tube or other source of polychromatic emission. X-rays from the anode of the x-ray tube fluoresce an adjoining, independent target that produces a monochromatic spectrum, a portion of which is focused by the x-ray optical system. This two-stage method gives the system considerably versatility without undue loss in signal. The two-stage concentrator makes practical the use of focusing optics in hand-held and portable instruments.
