    Abstract: A method and an apparatus for locally applying material to the surface of an anode of an X-ray source as well as a corresponding anode is presented. Anode material such as a repair material for filling a recess (121) in an X-ray emitting surface (115) is applied to the X-ray emitting surface of an anode (101). The location where such material is to be applied may be detected using a laser beam (133). The applied repair material including particles (41) of anode material such as tungsten, rhenium or molybdenum, is subsequently locally sintered using a high-energy laser beam (151). The sintered material may then be melted using a high-energy electron beam (163). Using such method, a damaged surface of an anode may be locally repaired. Alternatively, structures of different anode materials or of protrusions having different levels can be provided on the X-ray emitting surface (115) in order to selectively manipulate the X-ray emitting characteristics of the anode (101).

    Abstract: Disclosed is a cascade voltage amplifier for producing an amplified output in pulse or continuous wave form comprises at least one non-final stage with an electron tube configured as a switching and Class A or C amplifying structure. A final stage comprises an electron tube configured as a Class A or C amplifying structure.

    Abstract: A multiple focal spot X-ray tube (100) comprising an electron source (105), which is adapted to generate an electron beam (106), an anode (110), which is arranged within the electron beam (106) and which comprises a first focal spot portion (120) and a second focal spot portion (130), whereby the second focal spot portion (130) is spatially separated from the first focal spot portion (120). The X-ray tube (100) further comprises a first electron beam manipulation unit (125), which is adapted to interact with the electron beam (106), when the electron beam (106) impinges onto the first focal spot portion (120), and a second electron beam manipulation unit (135), which is adapted to interact with the electron beam (106), when the electron beam (106) impinges onto the second focal spot portion (130). By assigning one electron beam manipulation unit (125, 135) to each of the focal spot portions (120, 130), a precise focusing of the X-ray beam can be realized individually for each focal spot of the X-ray tube (100). Preferably, the first and the second focal spot portions have a distance along the axis of a rotating anode.

    Abstract: A method and apparatus, such as a spectrometer, are provided for facilitating the detection of an gamma signal in a manner that effectively discriminates the gamma signal from noise. A spectrometer may be provided which includes an gamma converter for converting gamma signals which impinge thereupon into corresponding pairs of electrons and positrons. The spectrometer also includes a deflector for separately deflecting the electrons and the positrons as well as electron and positron detectors for separately detecting the deflected electrons and positrons, respectively. As such, an gamma signal can be identified in instances in which the deflected electrons and positrons are detected in coincidence.
