NMR detection probe

摘要

A cooled NMR detection probe including a detection coil and an internal structure (65) mounted in a vacuum vessel (58) includes a radiation shield assembly (68), a connecting member (74), and a heat exchanger (80). The internal structure (65) is secured to the vacuum vessel (58) by a holding member (66). If the internal structure shrinks during cooling, the position of an upper portion of the first heat exchanger (80) hardly varies, thus suppressing displacement of a core module (54).

主权项

1. An NMR detection probe comprising:
a vacuum vessel inserted in a static magnetic field generator and extending along a central axis, the vacuum vessel having a bottom at a bottom height; an internal structure mounted in the vacuum vessel and having a detection coil for detecting an NMR signal emanating from a sample and a cooling source for cooling the coil; and a holding member for holding the internal structure to the vacuum vessel above the bottom height of the vacuum vessel as viewed along the central axis, said holding member having an elongated portion extending along the central axis between the vacuum vessel and the internal structure.
