    Abstract: The invention relates to a method and to a device for the electromagnetic stirring of electrically conductive fluids in the liquid state and/or in the state of onsetting solidification of the fluid, using a rotating magnetic field that is produced in the horizontal plane of a Lorentz force. The aim is to achieve an intensive three-dimensional flow on the inside of the fluid for mixing in the liquid state up to the direct vicinity of solidifying fronts, and to simultaneously ensure an undisturbed, free surface of the fluid. The solution is to change the direction of rotation of the magnetic field rotating in the horizontal plane at regular time intervals in the form of a period duration, wherein the frequency of the directional change of movement of the magnetic field vector is adjusted such that in the state of mixing the liquid fluid a period duration is adjusted between two directional changes of the magnetic field during a time interval as a function of the adjustment time with the condition (I) 0.5·ti.a

    Abstract: It is an object of the present invention to specify an arrangement for X-ray computed tomography, which allows continuous three-dimensional imaging of the examination object or a partial volume of the examination object at a high temporal and spatial resolution, wherein a high spatial resolution defines both a high resolution within the slice plane and also in the axial direction.

    Abstract: The invention relates to a measuring assembly (10) for determining a distribution of the magnetic gradient force, comprising a probe body (20) in which a hollow space (25) is formed. There is a probe suspension (30) in the hollow space (25), which contains a fluid (31) and at least one diamagnetic particle (35). A measuring device (40) is designed to determine a distance d of the diamagnetic particle/s (35) relative to a reference plane (29) on the probe body (20). A probe positioning unit (60) is designed to determine a geometric location of the hollow space (25) and/or the at least one particle (35) relative to a stationary reference location (69) outside the probe body (20).

    Abstract: The invention relates to an adjusting device for spatially adjusting the position of an object, comprising a plurality of plate elements which are arranged one over the other and which have radial guide structures that engage into one another at mutually facing sides, wherein at least one pair of movement plates and a pair of inclination plates are arranged on a base. The movement plates have a constant thickness, and the respective upper radial guide structures and lower radial guide structures of each movement plate are offset eccentrically relative to one another. The inclination plates have a variable thickness, and the respective upper radial guide structures and lower radial guide structures of each inclination plate are arranged concentrically to one another.

    Abstract: Extremely ultrashort and short-wave light pulses are generated with the aid of the traveling-wave Thomson scattering process. Dispersive elements are arranged between an electron, particle, or radiation source, which is synchronized with a laser system, and an optical element that focuses in a direction. The device is used to superpose a pulse-front tilted light pulse of high power with an ultrashort pulse of relativistic electrons in a laser-line focus. By varying the laser pulse-front tilt, narrow-band radiation pulses in a wide wavelength range from EUV to X-ray wavelengths and having a high number of protons are obtained, and the bandwidth and coherence properties can also be modified. The system can be used, among other things, in EUV lithography, in the planning and optimal design of laser systems and electron sources, in material analysis by phase contrast imaging, and in superconductor research. The assembly is smaller and cheaper than current comparables.

    Abstract: An assembly for electron beam tomography affords continuous and simultaneous recording of two-dimensional slice images of an object in different irradiation planes with a high temporal and spatial resolution. Targets are penetrated by openings of a given width and with a regular arrangement in the circumferential direction. The openings in the targets are respectively situated on a path formed by the cross section of the shell of the electron beam cone with the respective target. The successive targets in the beam direction respectively are arranged with a small angular offset with respect to the optical axis to the respective target situated in front, and so an electron beam circulating along the shell of the electron beam cone successively irradiates the material webs between the openings of all targets with at least part of its cross section and an X-ray detector arc is arranged for each target in coplanar radial fashion in front of or behind the respective target.
