    摘要: The invention concerns an NMR (nuclear magnetic resonance) high field magnet coil system comprising superconducting conductor structures for generating a homogeneous magnetic field B0 in a measuring volume (23) with several radially nested solenoidal coil sections (12, 13, 31), which is characterized in that the radially innermost coil section (31) is wound with a band-shaped superconductor with an aspect ratio (width to thickness) >3 on a coil support which axially projects, at least at one axial end, past the winding packet of the radially neighboring coil section (12) and the band-shaped superconductor is guided on this side tangentially towards the outside to a region of reduced magnetic field strength and terminates in at least one electrical connecting point (16). This permits use of a brittle band-shaped superconductor for the innermost coil system (31) which cannot be strongly bent at the upper edge.

    摘要: A superconducting very high field magnet coil with several solenoidal multi-layer coil sections which are wound in layers onto a hollow cylindrical support body (3) about a common central axis a, and which are electrically connected in series to carry a current in excess of 100 A is characterized in that the radially innermost coil section (1) comprises superconducting wire (2) which contains oxidic, high temperature superconductor (HTS) material, wherein the layers of the radially innermost coil section (1) are helically wound such that there is a free axial space between the walls, which is then sealed. The corresponding production method comprises the steps of helically winding a layer of superconducting HTS wire together with a filler wire onto the support body; removing the filler wire from the support body; repeating steps (a) and (b) until a desired number of layers of the coil section is obtained; thermally treating the winding packet for reacting the HTS material under a gaseous atmosphere containing O2 with optimized annealing parameters; and sealing the hollow spaces of the coil section. This permits production of an NMR-capable solenoid coil having only a few superconducting joints, of topologically simple construction that can carry a current of a few hundred amperes and which contains HTS material to produce magnetic fields in excess of 21 Tesla.

    摘要: An X-ray analysis device makes use of a variable aperture for controlling the position and cross section of the X-ray beam. The variable aperture is configured to allow changes in the cross section and/or position of the beam by movement of one aperture component in one direction. In one embodiment, the aperture medium is a perforated disk that is rotated to expose different aperture holes to the beam. In another embodiment, the aperture medium is a perforated tape that is moved in a linear direction to expose different aperture holes to the beam. The tape may be wound about two axes to control its movement, or may be a continuous loop. A cassette may also be used to house the tape.
