Abstract
A resonator which is arranged on a hollow cylindrical support (1) for the taking of high resolution magnetic nuclear resonance spectra from a sample extending along the cylinder axis within the resonator, and having a shielding (2) which defines the sensitive region of the resonator axially along a certain length which is shorter than the axial extent of the support (1), is characterized in that the resonator is configured as an axially symmetric bird-cage resonator. It only produces static field distortions in its sensitive region which are easily correctable, has an improved fill-factor and reduced ohmic losses, and produces a homogeneous RF field while avoiding topological problems occurring with quadrature detection.
