Cooled NMR probe
A nuclear magnetic resonance (NMR) probe is offered which can minimize positional shift of the detector portion (1) caused by shrinkage of the support post (17) due to cooling of the detector portion. The NMR probe has a vacuum-insulated container (13) and the detector portion (1) described above. T...

| Zusammenfassung: | A nuclear magnetic resonance (NMR) probe is offered which can minimize positional shift of the detector portion (1) caused by shrinkage of the support post (17) due to cooling of the detector portion. The NMR probe has a vacuum-insulated container (13) and the detector portion (1) described above. The container (13) has a cylindrical portion (41) inserted in a magnet. The detector portion (1) is made up of a detection coil (2) and a tuning and matching circuit (3) that are placed within the container (13). The detector portion (1) is cooled by a cooling means (8) such that NMR signals are detected with enhanced sensitivity. This probe is characterized in that the detector portion (1) is mounted to the upper end surface or a side surface of the cylindrical portion (41). |
