Abstract
An RF resonator for resonant transmission and/or reception of RF-pulses at a desired resonance frequency into or out of a sample (5) within an investigational region in a homogeneous magnetic field B.sub.0 of an (NMR)-apparatus has at least two spatially separated superconducting components (1, 1a, 1b, 1c, 1d) which do not constitute, either alone or in combination, a closed resonance system capable of resonating at the desired resonant frequency. Normally conducting connection elements (2a, 2b) are therefore provided to connect the superconducting components conductively and/or capacitively in such a fashion that the superconducting components, together with the normally connecting components, form one or a plurality of closed resonance systems capable of resonating at the desired resonant frequency. In this fashion, despite use of flat superconducting materials, a substantially higher fill factor, a very good homogeneity of the B.sub.0 -filed, and a signal-to-noise ratio corresponding to that of prior art are achieved but with high RF-power and a short excitation pulse decay time.
