摘要： An MAS NMR probe head arrangement has a stator (2) aligned along an axis of rotation (RA) to support a rotor (1), a stator mount (32), and a RF coil arrangement (21) to emit/receive RF pulses into/from the measurement substance (40) in the rotor. The stator mount has a stator bearing (41) into which the stator can be axially inserted and extracted. The stator, when inserted, passes through the RF coil arrangement (21), and can be fed through the RF coil arrangement (21). A mechanism fixes the stator axially in the stator bearing (41) when inserted. This arrangement enhances both ease of assembly and maintenance of the arrangement.
