Abstract: An electromagnetic pump for pumping an electrically conductive liquid, including a first conduit section and a second conduit section. The electromagnetic pump further includes a current generator arranged to provide an electric current through the liquid in the first conduit section and the liquid in the second conduit section such that a direction of the electric current is intersecting the flow of the liquid in the first conduit section and in the second conduit section, and a magnetic field generating arrangement arranged to provide a magnetic field passing through the liquid in the first conduit section and the second conduit section such that a direction of the magnetic field is intersecting the flow of the liquid and the direction of the electric current.

Abstract: The invention relates to an x-ray source (100; 100a; 100b; 100c), comprising an electron source (110) for providing electrons (e) in the form of an electron beam (es) and a target element (120), on which the electrons (e) of the electron beam (es) of the electron source (110) are able to impinge, and at least one deflection device (140) enabling the electron beam (es) to be deflected from a propagation direction produced by the electron source (110), wherein the at least one deflection device (140) is configured to deflect the electron beam (es) at least intermittently with a trajectory (180) incident on the target element (120), but outside a center of the target element (120) or a region (150) of the target element (120) on which the electron beam (es) is incident in the case of a propagation direction without deflection, or wherein the at least one deflection device (140) is configured to deflect the electron beam (es) at least intermittently in such a way that the electron beam (es) is not incident on the target element (120).

Abstract: A monolithic housing for an x-ray source can wrap at least partially around a power supply and an x-ray tube. The monolithic housing can include Al, Ca, Cu, Fe, Mg, Mn, Ni, Si, Sr, Zn, or combinations thereof. Mg can be a major component of the monolithic housing. The monolithic housing can be formed by injection molding. The monolithic housing can provide one or more of the following advantages: (a) light weight (for easier transport), (b) high electrical conductivity (to protect the user from electrical shock), (c) high thermal conductivity (to remove heat generated during use), (d) corrosion resistance, (e) high strength, and (f) high electromagnetic interference shielding (to shield power supply components from external noise, to shield other electronic components from power supply noise, or both).

Abstract: Electrons can rebound from an x-ray tube target, causing electrical-charge build-up on an inside of the x-ray tube. The charge build-up can increase voltage gradients inside of the x-ray tube, resulting in arcing failure of the x-ray tube. Also, the electrical charge can build unevenly on internal walls of the x-ray tube, causing an undesirable shift of the electron-beam. An x-ray tube (10 or 20) with multiple protrusions (19) on an interior wall of a drift-tube (18) can reduce this electrical-charge build-up. The protrusions (19) can reflect stray electrons back to the anode target (14), thus suppressing backscatter. Each protrusion (19) can have a peak (19p) extending into the hole (18h), and receding to a base (19b) farther from the electron-beam, on an entry-side (19en) nearest the drift-tube-entry (18en) and on an exit-side (19ex) nearest the drift-tube-exit (18ex).
