摘要： A coil (1) for a probe head (2) of a magnetic resonance spectrometer comprising a rotor (3), is configured to transmit a radiofrequency signal in order to excite a sample being received in the rotor (3) and/or configured to receive a radiofrequency signal being emitted by the sample. The coil (1) comprises a plurality of turns (4, 4a, ...) that are arranged along a coil axis (C) extending along the coil (1) and that define an ellipsoid shape, preferably a spherical shape. A probe head (2) for a probe of a magnetic resonance spectrometer comprises a rotor (3), a rotation device (9) being configured to generate a rotation of the rotor (3), and a coil (1).The rotation device (9) comprises a fluid supply device (6) and/or a fluid directing device (10). The fluid supply device (6) comprises a plurality of fluid apertures (7, 7a, ...) being arranged in a common plane (P). The fluid directing device (10) comprises or consists of the coil (1).

摘要： A stator (1) for a probe (2) of a magnetic resonance spectrometer comprises a receptacle (4) for receiving a rotor (3), wherein the receptacle (4) is configured such, that a rotor (3) being received in the receptacle (4) is rotatable about an axis of rotation (R), and at least one rotation device (5) that is configured to generate a rotation of the rotor (3) being received in the receptacle (4) about the axis of rotation (R). The stator (1) further comprises at least one adjustment device (6) that is configured to generate a force on the rotor (3) being received in the receptacle (4) so as to adjust the axis of rotation (R) of the rotor (3) relative to an adjustment axis (A) of the stator (1).
