Abstract
A method for operating an NMR probehead () with an MAS stator () receiving a circular-cylindrical hollow MAS rotor () with an outer jacket. The MAS rotor is mounted on pressurized gas in a measuring position within the MAS stator via a gas supply device with a bearing nozzle (') and rotates about the cylinder axis of the MAS rotor at a rotation frequency f≥30 kHz. During a measurement, a temperature control gas is blown by a temperature control nozzle () onto the outer jacket of the rotor at an angle α<90° with respect to the longitudinal axis of the cylinder-symmetrical rotor. The flow speed of the temperature control gas corresponds in the nozzle cross section to at least half the circumferential speed of the outer jacket of the rotating rotor and to at most the speed of sound in the temperature control gas.
