Abstract
A shim device having an HTS shim conductor track (C) and a shim switch (Sw) The track (C) is curved around an axis (z) and the shim switch is arranged in a first conductor track portion (S), to interrupt its superconducting state. The track (C) extends around at least a first opening (O) and a second opening (O) such that the track (C) has a first circumferential current path (L), a second circumferential current path (L) and a third circumferential current path (L). Two of the three paths (L, L, L) each surround only one of the two openings and one of the three paths (L, L, L) surrounds both openings. The first portion (S) is part of only the first path (L) and the second path (L). This produces a persistent HTS shim for field homogenization, allowing both a complex field distribution and a large degree of design freedom.
