Abstract

A resonator for magnetic resonance applications has a conductor element that extends from a first conductor end to a second conductor end. During operation of the conductor element at a resonance frequency, a resonance current-oscillates from the first conductor end to the second conductor end and back. The conductor ends are coupled with one another via a circuit that tunes the conductor element to the resonance frequency. The conductor element is fashioned as a multi-layer conductor with a number of layers that have first and second layer ends at the conductor ends. The circuit causes layer currents that are of equal magnitudes to flow in the layers themselves during active operation of the conductor element at the resonance frequency.
