Figure 5
Four permanent-magnet assemblies delivering at the sample position (i.e. on the central axis) a total static field of up to 1 T. (a) Cut of the 3D engineer design. (b) Photogaph of the setup, here shown during the commissioning phase. (c)–(e) Magnetic field measured along the s, x and z directions for a single magnet, as a function of distance and of magnet rotation angle. (f) Resultant field for the ensemble of the four magnets. Vertical bars indicate optimal magnet rotations for maximizing the field along the s direction while canceling it in the x direction. |
