CAPILLARY CARTRIDGE FOR MINIATURIZED NUCLEAR MAGNETIC RESONANCE (NMR) DEVICES

摘要

A shim coil assembly for positioning shim coils in a narrow gap between magnetic poles of miniature NMR devices around the magnetic center includes electric traces on multiple levels of printed circuit board layers in various, overlapping configurations. Mirror image shim coils can be connected in series in a symmetric sense or connected in series in a antisymmetric sense.
