A magnet arrangement arranged radially around a sample volume generates a changing magnetic field B with a z-direction component. A circuit board arrangement () is arranged radially within the magnet arrangement and has electrical conductor tracks () divided into conductor track sections (), at least two adjoining ones of which form a structure section (a,b) spanning an area (A, A). For each conductor track (), two structure sections (a,b) respectively form a structure section pair (), wherein the conductor tracks are arranged on the circuit board arrangement () such that equal and opposite voltages and/or currents are induced by a change in the magnetic field B of the magnet arrangement in the two structure sections of each structure section pair. As a result, eddy currents and resultant interference in the circuit board and the components thereof are avoided or at least minimized.

Imaging device, method for designing a circuit board arrangement, and circuit board arrangement

A winding machine () for winding solenoid-shaped coils () with band-shaped conductors (), comprising a winding means () which holds a circular-cylindrical coil core () of a coil () to be wound, and a winding drive which rotates a coil core (), which is held in the winding means (), about a winding axis W, wherein the winding means () can be moved in a first direction A by an axial drive, the direction A preferably extending approximately parallel to the winding axis W, is characterized in that the winding means () can be rotated about a pivot axis S by a pivot drive, wherein the pivot axis S extends perpendicularly to the direction A. The winding machine winds a solenoid-shaped coil with several layers of a band-shaped conductor without damaging the band-shaped conductor, in particular, when the band-shaped conductor contains brittle superconducting material.
