Abstract
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.
Claims23
A magic angle spinning (MAS) nuclear magnetic resonance (NMR) probe head arrangement, comprising:
- a stator aligned along an axis of rotation and configured to support a rotor holding a measurement substance,
- a stator mount,
- a radio frequency (RF) coil arrangement configured to emit RF pulses into the measurement substance held in the rotor and/or to receive RF signals from the measurement substance held in the rotor, and
- a mechanism,
- wherein the stator mount is formed with a stator bearing configured for axial insertion and extraction of the stator,
- wherein the stator is configured to pass through the RF coil arrangement for insertion into and extraction from the stator mount, and
- wherein the mechanism is configured to fix the stator axially in the stator bearing when the stator is inserted into the stator mount.
