Abstract:
A nuclear magnetic resonance(=NMR) probehead, comprising N basic elements (10a, 10b, 10c), where N≧2, wherein each basic element (10a, 10b, 10c) comprises a measurement sample (11) and a resonator system (12a, 12b, 12c), and wherein the N resonator systems (12a, 12b, 12c) of the N basic elements (10a, 10b, 10c) are coupled to each other, is characterized in that a coupling network for the N resonator systems (12a, 12b, 12c) is provided, with which the totality of the N resonator systems (12a, 12b, 12c) can be operated in one identical, coupled mode during transmission and reception, wherein the coupling network comprises a shared receiver circuit for the totality of the N resonator systems (12a, 12b, 12c). With the inventive NMR probehead, a better signal-to-noise ratio can be achieved in the case of lossy samples than with probeheads according to the prior art.
