An NMR (nuclear magnetic resonance) sample head comprising a microwave resonator comprising at least two elements which are reflective in the microwave range, at least one of which is focusing, wherein the reflective elements at least partly delimit a resonance volume of the microwave resonator, is characterized in that at least one of the reflective elements is embodied as a DBR ("Distributed Bragg Reflector"), and in that the NMR sample head comprises at least one NMR coil integrated into the DBR. Thus, an NMR detection coil can be positioned particularly near to the sample and the distortions of the static field by resonator components are reduced, such that the detection sensitivity and the spectral resolution of the experiment are significantly improved. |
